65 less than a number equals -49
Answer:
x-65=-49 (x=16)
Step-by-step explanation:
65 less (_-65)
than a number (x)
equals -49 (=-49)
combined x-65=-49
extra part: -49+65=16
Answer:
The answer is 16
Step-by-step explanation:
-49 + 65 = 16
Since it says 65 less than a number the equation would look like ?-65= -49. What I did was add -49 to 65 and I got 16.
Find an equation of the vertical line through (- 1/8, 4/3)
The equation of the line is
(Type an equation. Use integers or fractions for any numbers in the equation.)
Answer:
[tex]x=-1/8[/tex]
Step-by-step explanation:
Since this is a vertical line, our x-value stays constant no matter what y is.
So, the x is constant while the y changes.
Therefore, the equation of our vertical line will simply be the x-value of our coordinate point.
Our point is (-1/8, 4/3).
The coordinate is -1/8.
Therefore, our equation is:
[tex]x=-1/8[/tex]
And we're done!

find the circumference of a circle that has a radius of 212 mm
Answer:
1332.04
Step-by-step explanation:
C=2πr=2·π·212≈1332.03529
Answer:
1332.035 millimeters
Step-by-step explanation:
If you know the diameter or radius of a circle, you can work out the circumference. To begin with, remember that pi is an irrational number written with the symbol π. π is roughly equal to 3.14. You can also work out the circumference of a circle if you know its radius. Remember that the diameter is double the length of the radius. We already know that C = πd. If r is the radius of the circle, then d = 2r. So, C = 2πr.

Answer:
[tex]x<4[/tex]
Step-by-step explanation:
[tex]-3x-5-2x>-25[/tex]
Subtract the x terms:
[tex]-5x-5>-25[/tex]
Add 5 to both sides:
[tex]-5x-5+5>-25+5[/tex]
[tex]-5x>-20[/tex]
Multiply both sides by -1 and flip the inequality symbol:
[tex]5x<20[/tex]
Divide both sides by 5:
[tex]\frac{5x}{5}<\frac{20}{5}[/tex]
[tex]x<4[/tex]
Answer:
Option 1
Step-by-step explanation:
Step 1: Write inequality
-3x - 5 - 2x > -25Step 2: Solve for x
Combine like terms: -5x - 5 > -25Add 5 to both sides: -5x > -20Divide both sides by -5: x < 45x^2+5x-x^2+3x-7-12

Write and solve an equation and then check your answer. Complete the statements. Graciella divided her grapes equally among 6 friends. If each friend received 16 grapes, how many grapes did Graciella have? The variable, g, represents . The equation that correctly models the problem is . To undo what has been done to the variable, on both sides of the equation. The solution of the equation is . Check the solution by substituting in for g and simplifying.
Answer:
The variable, g, represents
✔ the number of grapes Graciella had
.
The equation that correctly models the problem is
✔ g/6 = 16
.
To undo what has been done to the variable,
✔ multiply by 6
on both sides of the equation.
The solution of the equation is
✔ g = 96
.
Check the solution by substituting
✔ 96
in for g and simplifying.
The solution of the equation will be g = 96.
What is an expression?In mathematics, expression is defined as the relationship of numbers, variables, and functions using mathematical signs such as addition, subtraction, multiplication, and division.
The variable, g, represents the total number of grapes that Graciella had.
The equation that correctly models the problem is:
g/6 = 16
To undo what has been done to the variable, we can multiply both sides of the equation by 6:
g = 6 x 16
g = 96
Therefore, Graciella had 96 grapes.
To check the solution, we substitute 96 for g in the original equation:
g/6 = 16
96/6 = 16
16 = 16
The equation is true, so our solution of g = 96 is correct.

Determine the domain of (f/g)(x) when f(x)=1/x and g(x)= sqrt x+8
(answer choices in photo)
Answer:
(−8,0)∪(0,∞)
Step-by-step explanation:
This is composition, which I'm going to assume you've covered (sorry if I use any weird terms because of that).
So, anyway, (f/g)(x) is basically [tex]\frac{f(x)}{g(x)}[/tex].
In this case, the answer would be [tex]\frac{\frac{1}{x} }{\sqrt{x+8} }[/tex]
I'm going to assume we're using the real number system.
In that case, x can't be less than 0 (can't even be equal to because divide by zero error
So, [tex]\sqrt{x+8} > 0[/tex]
Solve for x by squaring.
[tex]\sqrt{x+8} > 0[/tex]
[tex]x > -8[/tex]
However, in the numerator, there is 1/x. A number divided by 0 is undefined. So, x has to be greater than -8, and it can't be 0.
So, with that, the interval notation is like this.
(−8,0)∪(0,∞)

Digital Cameras
The cost and revenue equations for a company that sells digital cameras are given by
R(x) = x(125 -0.0005x)
And
C(x) = 3.5x + 185000
Where R and C are measured in dollars and x represents the number of cameras sold. How many
cameras must be sold to obtain a profit of at least $6,000,000?
Answer:
283,957 cameras
Step-by-step explanation:
Profit generated = cost - Revenue
Given
Cost function C(x) = 3.5x + 185000
Revenue function R(x) = x(125 -0.0005x)
Profit = $6,000,000
To get the value of x, we will substitute the given parameters into the formula as shown;
$6,000,000 = 3.5x + 185000 - x(125 -0.0005x)
$6,000,000 = 3.5x + 185000 - 125x +0.0005x²
0.0005x²-121.5x + 185000 - 6,000,000 = 0
0.0005x²-121.5x-5815000 = 0
On solving the resulting quadratic equation
x = 283,956.91736581 and -40956.917365805
Ignoring the negative value, the minimum camera that must be sold is approximately 283,957 cameras

Wade and Alexandra are 240 feet apart when they start walking toward one another. Alexandra walks twice as fast as Wade so whenever Wade travels x feet, Alexandra travels 2x feet. Let z represent the number of feet Wade has
traveled since he started walking toward Alexandra.
Answer:
The initial distance between Wade and Alexandra is 240ft.
They walk towards each other.
Alexandra walks twice as fast as Wade.
Now, because they are walking towards each other, when the distance walked by both of them equals 240 ft, they will meet.
Then:
if Wade walks z ft, Alexandra walks 2*z ft.
So we have the equation:
Distance that Wade walked + Distance that Alexandra walked = 240ft
z + 2*z = 240ft
3*z = 240ft
z = 240ft/3 = 80ft
They will meet when Wade walks 80ft.
Complete question :
Wade and Alexandra are 240 feet apart when they start walking toward one another. Alexandra walks twice as fast as Wade so whenever Wade travels x feet, Alexandra travels 2x feet. Let z represent the number of feet Wade has
traveled since he started walking toward Alexandra.
Write an expression in terms of z to represent the total number of feet Wade and Alexandra have walked toward one another.
b. Write an expression in terms of z to represent the distance (in feet) between Wade and Alexandra
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Initial distance between Wade and Alexandra = 240 feets
Alexandra walks twice as fast as wade :
Feets traveled by Wade = x
Feets traveled by Alexandra = 2x
Let z = feets traveled by wade since he started walking towards Alexandra
A.) Number of feets they've traveled towards one another in terms of z:
Number of feets traveled by wade = z
Number of feets traveled by Alexandra = 2z
Hence, total feets traveled towards one another :
(distance covered by Wade + distance covered by Alexandra)
= ( z + 2z) = 3z feets
B.) Distance between Wade and Alexandra:
Initial distance - distance covered
(240 - 3z) feets
A rectangle has a perimeter of 30 ft. Find a function that models its area A in terms of the length x of one of its sides. What side length, x, yields the greatest area. What is that area?
Answer:
Step-by-step explanation:
Let the other side of the rectangle be y. The perimeter of the rectangle is expressed as P = 2(x+y)
Given P = 30ft, on substituting P = 30 into the expression;
30 = 2(x+y)
x+y = 15
y = 15-x
Also since the area of the rectangle is xy;
A = xy
Substitute y = 15-x into the area;
A = x(15-x)
A = 15x-x²
The function that models its area A in terms of the length x of one of its sides is A = 15x-x²
The side of length x yields the greatest area when dA/dx = 0
dA/dx = 15-2x
15-2x = 0
-2x = -15
x = -15/-2
x = 7.5 ft
Hence the side length, x that yields the greatest area is 7.5ft.
Since y = 15-x
y = 15-7.5
y = 7.5
Area of the rectangle = 7.5*7.5
Area of the rectangle = 56.25ft²
