g(x) = x - 7
(f + g)(-3) =
(f - g)(-3) =
(g - f)(-2) =
Answer:
See attached image.
Step-by-step explanation:
Calculate the vales of each function (f and g) for the value of x as indicated. Then perform the arithmetic operation on the results. For example:
f(-3) = 10
g(-3) = -10
Then (f+g)(-3) is 10 - 10 = 0
(f-g)(-3) is 10 -(-10) = 20
and so on, as shown.

A rectangular prism has the volume of 528 cubic
feet and a base area of 88 square feet. What is the
height of the rectangular prism?
A. 2 feet
B. 8 feet
C. 4 feet
D. 6 feet
Answer:
D. 6 feet
Step-by-step explanation:
The volume of a rectangular prism can be found by using L * W * H, or B * H
-> The length (L) times the width (W) is equal to the base (B)
V = B * H
528 = 88H
6 = H
Alexa always gives a 15% tip when she eats at a
restaurant. She gives a $2.13 tip. What was the
cost of her meal?
the cost of her meal was "x", which is the 100% of her bill, we also know that $2.13 is 15% of that, so
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 2.13&15 \end{array}\implies \cfrac{x}{2.13}=\cfrac{100}{15}\implies \cfrac{x}{2.13}=\cfrac{20}{3} \\\\\\ 3x=42.6\implies x=\cfrac{42.6}{3}\implies x=14.2[/tex]
Which of the following functions, when graphed, is a line with a downward slant?
Answer:
Step-by-step explanation:
A function with a downward slant must have a negative slope.
All these lines are in the format y = mx + b where m is the slope's value.
The only one that fits the requirement is choice (B) which has a slope of -4.
Hope that helps!
Please help! I’ll mark as brainliest
Answer:
see below
Step-by-step explanation:
domain is all x values for which a graph has
and range is all y values for which a graph has
domain in this case is -4<x<4. The range is -3<= x <= 3
Function is increasing when slope of the line is positive, function is decreasing when slope of the line is negative.
When 2 lines meet and there is an edge like at (-1,3) there is no increase of decrease of the function. If you are in calculus, this is because the derivative of the function will not be valid at those points. If you are not in calculus, then don't pay attention to the derivative stuff.
Function is increasing on interval -4<x<-1 and 2<x<4
Function is decreasing on interval -1<x<2

Construct a circle with a radius of 8cm, and draw an equilateral triangle inside it. Make sure the length of each side measures to 15.6 cm.
Answer:
Diagram 1
Draw a circle with a radius of 8 cm, ensuring you have clearly marked the center point (black circle with center C1)
Add a point on the circumference of the circle (point C2)
Draw a second circle of radius 8cm with point C2 as its center (red circle with center C2).
Diagram 2
The red circle intersects the black circle at two points (D and E).
Connect these 2 points of intersection with a line segment.
Diagram 3
Draw a third circle with center D and radius DE (shown in blue)
This circle intersects the black circle at point F.
Diagram 4
Draw 2 line segments to connect points D and E with point F - this is your equilateral triangle inside the circle!

which of these functions is linear?
The only linear function is:
y = x - 5
So the correct option is B.
How to identify a linear function?
A linear function is a polynomial of degree 1, and can be written as:
y = a*x + b
So we have a coefficient multiplying the variable and a constant term, nothing else.
By comparing this with the options, we can see that the only linear function given is the one in option B.
y = x - 5
Where a = 1, and b = 5.

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
We are given that;
Length of string=8feet
Now,
This is a word problem on fractions that requires division. To solve it, you need to follow these steps1:
Define a variable. Let x be the number of bracelets Sienna can make.
Write an equation using the variable. Since she uses 1/4 of a foot of string for each bracelet, we can write: x * (1/4) = 8
Solve the equation. To isolate x, we need to multiply both sides by 4: x = 8 * 4
Simplify the expression
x = 32
Therefore, by the unitary method the answer will be 32.

Which are equivalent to 2 1/3 x
3/14 .? Check all that apply.
Answer:
The answer is 1, 3, and 5
Step-by-step explanation:
First, you have to solve the equation, making the mixed number fractions into improper fractions. You then get 7/3 x 3/14. You can cross cancel, and thus the equation on the top is equal to 1/2.
Solve the rest of them, the same way you did in the first, and you would get 1, 3, and 5.

A plumber charged x dollars per hour for a 4-hour job plus $175 for parts. The to- tal charge for the service call was $415.00. Which equation can be used to deter- mine how much the plumber charged per hour?
Answer:
4x + 175 = 415
Step-by-step explanation:
4 is the hours, so it should be multiplied by x to see how much you get every hour (and a total of 4 hours).
175 is the constant and should be added to the equation so that all fees are included.
415 is the total amount so the equation should equal that number.

You have a puppy named Fido and 60 feet of fencing. You want to make him the largest play area possible. What are the dimensions of the rectangular area that has the greatest area? Show why this is the biggest with diagram or charts
Answer:
15 feet x 15 feet
Step-by-step explanation:
I'm worried about Fido, so I'll use three different approaches to maximizing his play space: Graphing, Chart, and First Derivative. This is perhaps more than Fido wants, but it hopefully offers ideas on how these types of problems can be answered.
=========================
Fido is limited to 60 feet of fence, which will form the perimeter. The area of a rectangle is (length)*(width). Let's set length to L and width to W. I'll use A for area.
Therefore A = L*W
The rectangle's perimeter will be 2L + 2W, and this is equal to 60 feet:
2L + 2W = 60
Let's rearrange this equation to isolate either W or L. I chose L:
L + W = 30
L = 30 - W
Now let's use this definition of L in the Area equation:
A = L*W
A = (30-W)*W
A = 30W - W^2
Graphing
We can graph this function (A = 30W - W^2) to find the maximum area. See the attached image. We find a maximum area of 225 ft^2 when the width is 15 feet. 15 feet would mean that Fido's roaming pen will be in the shape of a square; 15 feet for each side equals 60 feet total fence.
Chart
One can also find a maximum by calculating a variety of conditions set by L = 30 - W. I randomly picked lengths from 2 to 24 feet and calculated the resulting width and then the resultant area for each condition. See attached image. Although I did not pick 15 feet, we can see that the area increases until the length transitions from 14 to 16 feet. It reverses direction at that point. A closer inspection around those values will show that 15 feet is, in fact, the optimum value to produce a pen with the most area.
First Derivative
One could also take the first derivative of the equation A = 30W - W^2 and set it equal to zero. The fist derivative tells us the slope of the line at any point (for a value of W in this example). The slope is zero only when the curve hits a maximum.
A = 30W - W^2
A' = 30 -2W
0 = 30 - 2W
2W = 30
W = 15 feet
The slope is zero when the width is 15 feet. 15 feet is the optimum for creating a pen with the most area possible with 60 feet of fence.
===
All three approaches yield the same result. Graphing is fun when you have access to DESMOS. Charts are fun if you like Excel. Derivatives can also be fun, mostly because I always ponder "Who had the audacity to think this might work?" (Didn't they have something more important to do? Raid a village, etc.?).
