7×14=98 the area of a rectangle
Answer: 98 ft²
Step-by-step explanation:
Length (L) = 2w
width (w) = w
Perimeter (P) = 2L + 2w
42 = 2(2w) + 2w
42 = 4w + 2w
42 = 6w
7 = w
L = 2w
= 2(7)
= 14
Area = L · w
= 14 · 7
= 98
-4|7 – 6k|= 14 solve for k
Answer:
no solution
Step-by-step explanation:
-4|7 – 6k| = 14
Divide both sides by -4.
|7 - 6k| = -14/4
|7 - 6k| = -7/2
An absolute value can never equal a negative number since an absolute value is always non-negative. Therefore, there is no solution.

Write the equation of the line in slope-intercept form that passes through the points (2, -2) and (-3, -17)
Answer: y = 3x - 8
Step-by-step explanation: If you’re given two points that lie on a line, and you’re asked to write the equation of the line, your first task will be to find the slope of that line using the slope formula.
The slope formula is m = y₂ - y₁ / x₂ - x₁
Substituting our points in, we have -17 - -2 / -3 - 2 which is -15/-5 or 3.
So the slope of our line is 3 which can be used with either one of our
two points to write the equation of the line in point-slope form.
So let's go with the point (2, -2).
Point-slope form is written y - y₁ = m(x - x₁).
Since we're using the point (2, -2), y - y₁ would be y - -2 or y + 2.
Now, m would be 3 and x - x₁ would be x - 2.
So we have y + 2 = 3(x - 2).
To put this equation into slope-intercept form, we would first distribute
the 3 through the parentheses which gives us y + 2 = 3x - 6.
Move the number to the right side of the equation by
subtracting 2 from both sides and we have y = 3x - 8.
So the equation of the line would be y = 3x - 8.

HURRY NEED ANSWER ASAP NOW PRONTO Simplify (−8.5)(−5)( −2). 850 85 −85 −850
Answer:
−85
Step-by-step explanation:
Let us restate the problem once more;
(-8.5)(-5)(-2) = ?
In mathematical problems as such, it is best to apply the order of operation called PEMDAS;
P = Parentheses
E = Exponent
M = Multiplication
D = Division
A = Addition
S = Subtraction
Between multiplication and division, we can carryout anyone first since division can be expressed as multiplication. This is also the case of addition and subtraction.
Note also, the negative sign.
+ x + = +
+ x - = -
- x - = +
Now, let us solve the problem;
(-8.5)(-5)(-2);
we simply solve from left to right; to remove the parentheses simply introduce the multiplication sign;
- 8.5 x - 5 x - 2 = 42.5 (-2)
= -85
Therefore, the expression resolves into -85.

Two numbers total 63 and have a difference of 31. Find the two numbers
Answer: 47 and 16
Step-by-step explanation:
- Make Two Equations
x + y = 63
x - y = 31
- Set one of the equations equal to one of the variables
x + y = 63
x = 31 + y
- Substitute the equation back into the other one
(31 + y) + y = 63
31 + 2y = 63
2y = 32
y = 16
- Substitute the answer back into the equation
x + y = 63
x + 16 = 63
x = 47
Answer:
47 and 16
Step-by-step explanation:
Start by writing this question as two equations, lets call the two numbers x and y.
"Two numbers total 63" we can write that as x+y=63
"...and have a difference of 31" we can write that as x-y=31 or y-x=31 or |x-y| = 31 or |y-x| = 31. There a lot of ways to write that.
So lets use y-x=31 as the second equation, you can ignore the other possible ways since it doesn't matter in this problem to use absolute value
Using subsitution solve for x using x+y = 63, x = -y + 63
Plug that into the other equation, -y+63-y=31
−2y+63=31 (Simplify both sides of the equation)
−2y+63+−63=31+−63 (Add -63 to both sides)
−2y=−32
y=16 (Divide both sides by -2 to get Y by itself)
We solved for Y(of of the numbers), now for X (the other number)
Substitute 16 for y in x= − y + 63:
x=−y+63
x=−16+63
x=47

Step-by-step explanation:
George Johnson recently inherited a large sum of money;he wants to use a portion of this money to set up a trust fund for his two children. The trust fund has two investment options: (1) a bond fund and (2) a stock fund. The projected returns over the life of the investments are 6 percent for the bond fund and 10 percent for the stock fund.Whatever portion of the inheritance he finally decides to commit to the trust fund, he wants to invest atleast 30 percent of that amount in the bond fund. In addition he wants to select a mix that will enable him to obtain a total return of atleast 7.5 percent.A) Formulate a linear programming model that can be used to determaine the percentage that should be allocated to each of the possible i nvestment alternativesB) Solve the problem using the graphical solution procedure.
The solution to the given question is "Optimal B = 0.3 and S = 0.7 where 0.088 was its optimal value", and further calculation can be defined as follows:
linear programmingIt is a mathematical formula with something like a system of linear as well as a set of linear programming in which there is a linear optimization problem to the Nonnegative parameters. In this, Let B compensate also for percentages of money held throughout the bond portfolio and S for both the percentage of money held throughout the bond fund.In a fund for stocks.
[tex]Max \ \ 0.06 \ b+0.1 \ S \ \ \ \\\\B \geq 0.3 \ \ \ \ \ \ \ \ \ \ \ \ \text{Bond fund minimum} \\\\0.06 \ B+ 0.1 \ S \geq 0.075 \ \ \ \ \ \ \text{Minimum return} \\\\B+S=1 \ \ \ \ \ \ \ \text{All funds invested}\\\\B,S\geq 0 \\[/tex]
For a maximization problem, just use 5 phases of the visual solution process. Start by measuring the rows which fit the disparities.[tex]B = 0.3 \\ \\0.06 \ B+0.1 \ S = 0.75\\\\ B+s =1[/tex]
It is the very first main principle to use a sign[tex]\geq[/tex], greater than or equal to, that answer is just all points because the third limitation uses an exclamation point, both places on the graph are the answer. Its colored area contains each resolution stage that concurrently fulfills all limitations its Viable Area was named as its location of the approaches to any inequalities. That ideal option exists in which there is limited restriction mostly on bond portfolio and all funds. Making investment constraints converge. Replacement B= 0.3 throughout the restriction invested throughout all resources and settle to S.[tex]B+s=1=10 \\\\0.3+s = 1 \\\\The \ \ s= 0.7 \\[/tex]

Make each expression a true statement
Answer:
( d / c ) < ( a / d )
( b / d ) < ( a / d )
( d / a ) < ( a / d )
Step-by-step explanation:
For this problem, we need to consider the given information that a > b > c > d > 0. Note that a is the greatest number and that d is the least number.
Given this fact, we can create a fraction that will result in a maximum value by simply doing the following:
a / d
The reason the fraction ( a / d ) results in a maximum, is because of the given information where a is the furthest from 0, and d is the closest to 0. Therefore, we can say that no other combination will result in a value greater than ( a / d).
So in the three given statements, we have different combinations of fractions being compared to our maximum value fraction. Our maximum value fraction ( a / d ) will always be greater than any other combination.
Thus, we will choose the sign that makes ( a / d ) greater than the other choice fractions.
Cheers.

A certain car rental location charges a daily fee as well as a mileage charge. On one trip a businessman rented a car for the day, drove it 150 miles. He was charged $79 (plus taxes). On another occasion when he rented a comparable car for the day, he drove it 65 miles and was charged $63.70 (plus taxes).
How many miles could the car be driven for $100 (without regard for any taxes that might be applied)? Round to a whole number of miles.
Answer:
[tex]x\approx 267\ miles[/tex]
Step-by-step explanation:
Linear Modeling
Some events can be modeled as linear functions. If we are in a situation where a linear model is suitable, then we need two sample points to make the model and predict unknown behaviors.
The linear function can be expressed in the slope-intercept format:
[tex]f(x)=mx+b[/tex]
For the problem at hand, we must pick the adequate variables according to the data provided.
The question states the charge for renting a car is a function of the mileage. It also provides two points from which we can build our model. Let's set the following variables:
c = the charge for renting a car in dollars
x = the distance driven by the businessman in miles
Representing the ordered pair as (x,c), we have the points: (150,79) and (65,63.70). Our model will be expressed as:
[tex]c = mx+b[/tex]
We must find the values of m and b with the data provided. Substituting the first point:
[tex]79 = 150m+b[/tex]
Substituting the second point:
[tex]63.70 = 65m+b[/tex]
Both equations form the following system:
[tex]\left\{\begin{matrix}150m+b=79\\ 65m+b=63.70 \end{matrix}\right.[/tex]
Subtracting both equations:
[tex]150m-65m=79-63.70[/tex]
Note the variable b was canceled out in the operation, leaving only the variable m to solve. Joining like terms:
[tex]85m=15.3[/tex]
Solving:
[tex]m=15.3/85=0.18[/tex]
From the first equation
[tex]79 = 150m+b[/tex]
Solving for b:
[tex]b=79-150m=79-150(0.18) = 52.[/tex]
The model for the problem is:
[tex]c=0.18x+52[/tex]
Now we need to calculate how many miles (x) could be driven for c=$100. From the equation above, substitute c=100
[tex]100=0.18x+52[/tex]
Solve for x:
[tex]0.18x+52=100[/tex]
[tex]0.18x=100-52=48[/tex]
[tex]x=48/0.18=266.67[/tex]
Rounding to the closest integer:
[tex]\boxed{x\approx 267\ miles}[/tex]
