Answer:
7
Step-by-step explanation:
An "additive inverse" refers to a number that when added to a specific number equals to "zero."
In the question above, the additive inverse of -7 is 7 because: -7 + 7 = 0
Other examples:
1. The additive inverse of 2 is -2 because: 2 + (-2) = 0
2. The additive inverse of -100 is 100 because: -100 + 100 = 0
3. The additive inverse of [tex]\frac{1}{2}[/tex] is -[tex]\frac{1}{2}[/tex] because: [tex]\frac{1}{2}[/tex] + -[tex]\frac{1}{2}[/tex] = 0
The additive inverse of -7 is equal to 7.
The additive inverse of a number is the number that, when added to the original number, gives a sum of zero.
To determine the additive inverse of -7, we need to find the number that, when added to -7, results in zero.
To do this, we can multiply -7 by -1, which is the multiplicative inverse of 1. Multiplying a number by its multiplicative inverse always gives the additive inverse of that number.
So, -7 multiplied by -1 is:
-7 x -1 = 7
Therefore, the additive inverse of -7 is 7.

A bag contains white,blue and red balls in the ratio 8:3:2.There are 10 red balls if 10 white balls and 10 blue balls are removed from the bag the new ratio is
Answer:
If you have 10 red balls, you have blue balls in proportion 3:2, so you have 15 blue balls. Moreover, you have white balls in proportion 8:2=4:1, so you have 40 white balls.
Removing 10 white and blue balls causes you to have 30 white, 10 red and 5 blue balls.
Since 30=5*6 and 10=5*2, the new proportion of white, red and blue balls is 6:2:1.

given the following function list the first 4 terms
f (n) = 5 (n + 2)
Answer:
15,20,25,30
Step-by-step explanation:
f (n) = 5 (n + 2)
Let n=1
f (1) = 5 (1 + 2)
= 5(3) = 15
Let n=2
f (2) = 5 (2 + 2)
= 5(4) = 20
Let n=3
f (3) = 5 (3 + 2)
= 5(5) = 25
Let n=4
f (4) = 5 (4 + 2)
= 5(6)=30
Answer:
15, 20, 25, 30
Step-by-step explanation:
To calculate the value of a term, you plug in the term value into the equation, which, in this case, means replacing the n with the term number.
Term 1:

Suppose that a family wants to increase the size of the garden which is currently 16 feet long and 8 feet wide without changing the basic shape of the garden. That is, the family wants to ensure that the length of the garden remains twice the width (see figure).
1. Write an equation for the area of the new garden.
2. Write an equation that calculates how much more area the new garden will have as compared to the current garden. Simplify the equation into a quadratic equation in standard form.
3. Using the equation from Exercise 2, determine what effect increasing the width of the garden by two feet will have on the length of the garden and the total area of the garden.
4. Using the equation from Exercise 2 and factoring, determine how much the width of the garden will need to be increased in order for the garden area to be 160 square feet larger than its original area.
5. Using the equation from Exercise 2 and factoring, determine how much the width of the garden will need to be increased in order for the garden area to be four times its original area.
Answer:
See below
Step-by-step explanation:
Sides of the garden
16 feet and 8 feetNew dimensions of the garden
16 + 2x and 8 + x1. The area of the new garden
(16 + 2x)(8 + x) = 2x^2 + 32x + 1282. The difference in area
2x^2 + 32x + 128 - 16*8 = 2x^2 + 32x3. x= 2 effect on the area
2*2^2 + 32*2 = 8 + 64 =72 ft²4. Area difference = 160
2x^2 + 32x = 160x^2 + 16x - 80 = 0Solving we get positive root of 4 ft5. Area difference = 4 times
2x^2 + 32x = 128*32x^2 + 32x - 384 = 0x^2 + 16x - 192= 0Solving we get positive root of 8 fteach term of a sequence is 2 more than the previous term. if the third term is 8 find the first five terms of the sequence

Step-by-step explanation:
Given F(h)=9h+8 , find : f(3)
Answer: f(x) = x9h(x)
h(-1) = 2
h'(-1) = 5
We need to find h(x) first. Once we have h(x), we can find the derivative of f(x). Then evaluate the derivate when x = -1.
We know that derivative is the slope of the tangent line. In this case, the slope of the line tangent to h(x) at x=-1 is 5.
h(-1) = 2 has a coordinate point of (-1, 2).
2 = 5(-1) + b
2 = -5 + b
7 = b
h(x) = 5x + 7 -----> equation of the tangent line
f(x) = x9(5x + 7)
f(x) = 5x10 + 7x9
Take the derivative of f(x).
f'(x) = 50x9 + 63x8
f'(-1) = 50(-1)9 + 63(-1)8
f'(-1) = -50 + 63
f'(-1) = 13
Step-by-step explanation:
Answer:
f(3) = 35
Step-by-step explanation:
Since we are given f(3), that means h = 3
f(3) = 9(3) + 8
f(3) = 27 + 8
f(3) = 35

Jamal drew the function below. Which explains whether or not his function is linear?
A)It is linear because it has a constant rate of change.
B)It is linear because it does not have a constant rate of change.
C)It is not linear because it has a constant rate of change.
D)It is not linear because it does not have a constant rate of change.
*the function drawn by Jamal is the attachment below
Answer:
A) It is linear because it has a constant rate of change.
Step-by-step explanation:
When you plot all the coordinates of a linear function on a graph, the line that passes through all the points plotted is typically a straight line. There would be absence of any curve or bends. All you'd have is a straight line.
Consequent on this, a straight line indicates that the rate of change remains the same along the line slope.
If you pick any two points on the line and calculate the rate of change, it would give you the same rate of change you'd get when you calculate the rate of change of another two points on the line.
A straight line indicates a constant rate of change. Therefore, the function drawn by Jamal is a linear function because it has a constant rate of change.

4(h + 12) = 80
Answer:
h=8
Step-by-step explanation: can u make me brainliest plz?
Step 1: Simplify both sides of the equation.
4(h+12)=80
(4)(h)+(4)(12)=80(Distribute)
4h+48=80
Step 2: Subtract 48 from both sides.
4h+48−48=80−48
4h=32
Step 3: Divide both sides by 4.
4h/4=32/4
h=8

Determine the intercepts of the line.
2x + 5y = -6
y-intercept: ?
r-intercept: ?
Answer:
y-int = (0,-6/5)
x-int = (-3,0)
Step-by-step explanation:
to find the ints you have to replace the values by zero
y-int :
2(0) + 5y = -6
0 + 5y = -6
5y = -6
y = -6/5
y-int = (0,-6/5)
x-int:
2x + 5(0) = -6
2x + 0 = -6
2x = -6
x = -6/2
x = -3
x-int: (-3,0)
Mrs. Chip bought 2 sheets and a blanket and paid $41. Mrs. Dale bought a sheet and 4 blankets and paid $80.
Answer:
Sheet = $12Blanket = $17Step-by-step explanation:
Let the cost of a sheet be s and cost of a blanket be b
2s + b = 41s + 4b = 80From the first equation we get:
b = 41 - 2sSubstitute in the second equation
s + 4*(41 - 2s) = 80s + 164 - 8s = 807s = 84s = 12Then
b = 41- 2*12 = 17Select ALL the sequences of transformations that could take Figure P to Figure Q

Solve for y.
-4y+7=-10v+37
Simplify your answer as much as possible.
Answer:y= 5/2v + −15/2
Step-by-step explanation:
−4y+7=−10v+37
Step 1: Add -7 to both sides.
−4y+7+−7=−10v+37+−7
−4y=−10v+30
Step 2: Divide both sides by -4.
−4y/−4 =−10v+30/−4
y= 5/2v + −15/2
