What is the domain of the function shown in the graph?
The domain of the function from the graph.
{10, 20, 40, 80}.
Option B is the correct answer.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
The coordinates from the graph:

since it's square units and this is a right triangle
area = (width * height) / 2
area = 6 * 3 / 2
area = 18 / 2
area = 9 square units²
Answer:
9 [tex]units^{2}[/tex]
Step-by-step explanation:
The formula to find the area of a triangle is [tex]A=\frac{1}{2}b*h[/tex] where b is the base or bottom of the triangle and h is the height of the triangle.
The base of the triangle in the picture is 6 units.
The height of the triangle in the picture is 3 units.
Substituting these values into the area formula:
[tex]A=\frac{1}{2}(6*3)=\frac{1}{2}(18)=9[/tex]
So the area of the triangle is 9 [tex]units^{2}[/tex]

Brenda thought of a number divided it by 5 and then added seven to her answer she got the final number 11 what was her starting number
Answer:
20
Step-by-step explanation:
lets assume the number she thought of was x
[tex] \frac{x}{5} [/tex]
then she added 7 to it and got 11
[tex] \frac{x}{5} + 7 = 11[/tex]
l.c.m
[tex] \frac{x + 35}{5} = 11[/tex]
cross multiply
[tex]x + 35 = 11 \times 5[/tex]
[tex]x + 35 = 55 [/tex]
[tex]x = 55 - 35[/tex]
x = 20
Compare the weather on two different days using an inequality. Then see if their comparisons change by finding the absolute value of each.
Day 1:
Day 2:
Inequalities are used to compare unequal expressions.
The actual comparison is:[tex]\mathbf{-3.5 < 5}[/tex] or [tex]\mathbf{5 > -3.5}[/tex]
The temperatures are given as:
[tex]\mathbf{Temperature = -3.5F,\ \ 5F,\ \ 1.5F,\ \ -0.5F,\ \ -2F,\ \ 2.5F,\ \ -4F}[/tex]
From the above list, we have:
[tex]\mathbf{Day \ 1= -3.5F}[/tex]
[tex]\mathbf{Day \ 2= 5F}[/tex]
By comparison,
[tex]\mathbf{-3.5 < 5}[/tex] or [tex]\mathbf{5 > -3.5}[/tex]
Using absolute values, the inequalities are:
[tex]\mathbf{|-3.5| < |5|}[/tex] or [tex]\mathbf{|5| > |-3.5|}[/tex]
Hence, the actual comparison is:

Jennifer has run many marathons and keeps track of all of her finishing times. At a marathon last month, she finished in 350 minutes. The other day, she ran another marathon and finished with a time of 406 minutes. What is the percent of increase in Jennifer's marathon time?
Answer:
16%
Step-by-step explanation:
406 / 350 = 1.16
406 is 116% of 350
so 350 + 16% is 406
because 350 * 0.16 = 56
56 is 16%
350 + 56 = 406

Answer:
I believe it should be (-7,-2)
Step-by-step explanation:
Anyone know these answers for math??
Answer:
7) No
8) Yes
Step-by-step explanation:
7) 15 + 2y = -12 - 4y when y = -0.5
15 + (2*-0.5) = -12 - (4*-0.5)
15 + -1 = -12 - (-2)
15 - 1 = -12 + 2
14 = -10
The numbers are different on both sides so -0.5 is not a solution
8) 5 - 2( 3x + 5 ) = 3 - 10x when x = 2
5 - 2( (3*2) + 5 ) = 3 - (10*2)
5 - 2( 6 + 5 ) = 3 - 20
5 - 2*11 = 3 - 20
5 - 22 = 3 - 20
-17 = -17
The numbers are similar on both sides so 2 is a solution

2. Deon wants to find the perimeter of a square with side length 6m - 3. Write two expressions that represent the perimeter, including one expression in simplest form. Perimeter of a square- p = 4(s) or p = s + s + s + s
Step-by-step explanation:
The perimeter of the given square is: a + a + a + a = 4 a units. Hence, the formula of the perimeter of a square = 4 × (length of any one side).
The expressions that represent the perimeter of the square are p = 4(6m-3) and p = 24m - 12. And p = 24m - 12 is the simplest form of the expression.
What is perimeter?A closed shape's perimeter is the sum of the lengths of its outside boundaries. The lengths of all the sides are added to determine the measurement.
Given:
The side of the square is 6m-3 unit.
And all the sides of the squares are equal.
And the perimeter p of the square is,
= the sum of all the sides.
p = 4 x one side.
p = 4(6m-3)
The above expression represents the perimeter of the given square.
Simplifying,
p = 24m - 12
This is the simplest form of the expression.
Therefore, the required expression are p = 4(6m-3) and p = 24m - 12.

What is the slope of the line that passes through the points (-10, 9)(−10,9) and (-12, 7) ?(−12,7)? Write your answer in simplest form
Answer:
I Had A Problem In This Too Lol Here Was Correct For Me
Step-by-step explanation:
Identify the coordinates (x₁,y₁)and(x₂,y₂). We will use the formula to calculate the slope of the line passing through the points (3,8) and (-2, 10).
Input the values into the formula. This gives us (10 - 8)/(-2 - 3).
Subtract the values in parentheses to get 2/(-5).
Simplify the fraction to get the slope of -2/5.
Answer:
slope = 1
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}x_{1} }[/tex]
with (x₁, y₁ ) = (- 10, 9 ) and (x₂, y₂ ) = (-12, 7 )
m = [tex]\frac{7-9}{-12-(-10)}[/tex] = [tex]\frac{-2}{-12+10}[/tex] = [tex]\frac{-2}{-2}[/tex] = 1
