Answer:
Step-by-step explanation: both graphed is D
The graph D represents the solution of the system of the equation.
What is the system of equation?One or many equation having same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
Given, the system of equation;
y = -3x - 5 {equation 1}
y = 3x + 1 {equation 2}
Add both of the equation:
2y = -4
y = -2
And x = 1
And the solution set is (1 , -2).
And only D have the solution set (1 , -2)
Therefore, the graph D represents the solution of the system of the equation.

What is the area of this compound shape?
Answer:
139.36
Step-by-step explanation:
first you do 8*8 because that would be the area of the square part
8*8=64
then find the area of the semicircle
first the Radis of it is 4 because 8/2=4
A=3.14R^2/2
3.14*4^2/2
3.14*16/2
50.24/2
25.12
now because there are 3 of the semicircles you do
25.12*3
75.36
then you add the 64 from the square to get your answer
75.36+64
139.36

Step-by-step explanation:
I need help with this equation for math
Answer:
The answer would be B
Step-by-step explanation:
the y-intercept would be a postive 4 and because it's a negative slope, it would rule out all of them except B.
Answer:
y = -1/2x +4
Step-by-step explanation:
We have two points so we can find the slope
m = (y2-y1)/(x2-x1)
= ( 0-4)/(8-0)
= -4/8
= -1/2
We know the y intercept is 4
The slope intercept form of the line is
y = mx+b where m is the slope and b is the y intercept
y = -1/2x +4
On a bicycle, Caitlyn rides for 4 hours and is 46 miles from her house. After riding for 7 hours, she is 79 miles away. What is her rate?
Answer:
Caitlyn's average is roughly 11.4.
Step-by-step explanation:
You get this by dividing 46 by 4, which gets you 11.5.
You then divide 79 by 7, that equals 11.3, rounded.
The number in-between the two numbers is 11.4.

2. A water tank is in the shape of a right circular cylinder with a height of 9
feet and a volume of 225 pi cubic feet. What is the diameter of the water
tank? *
Answer:
10 ft.
Step-by-step explanation:
V = Bh where B = area of the base, which is a circle in your problem.
So, B = [tex]\pi r^{2}[/tex]
225π = π[tex]r^{2}[/tex](9)
[tex]r^{2}[/tex] = 25
r = 5 ft
diameter = 2r = 10 ft.

the graph of g(x) =x -5 is a translation of the graph of the parent function 5 units
Answer:
the answer is: 8(x)= 4 -5
Step-by-step explanation:
The graph of parent function and translated function are given below. Therefore, the transformation is shifted down 5 units.
The given function is g(x)=x-5.
What is the translation?A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.
Here, parent function is g(x) = x
To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.
Shifted down: 5 units
The graph of parent function and translated function are given below. Therefore, the transformation is shifted down 5 units.

Answer:
Step 1 and step 2
Step-by-step explanation:
she has to subtract 30 not add 30.
2(3x+6)=3(x-10)
6x + 12 = 3x-30
6x +12 - 12 = 3x - 30 - 12
6x = 3x - 42
6x - 3x = 3x - 42 - 3x
3x = -42
3x/3 = -42/3
x = -14
Answer:
B
Step-by-step explanation:
Hey There!
So the first thing we're going to do is solve it and then compare it to Maya's steps to see where she made the mistake
2(3x+6)=3(x-10)
step 1 distribute the 2 to whats inside of the parenthesis (3x+6)
2*3x=6x
2*6=12
now we have
6x+12=3(x-10)
step 2 distribute 3 to what's inside of the parenthesis
3*x=3x
3*-10=-30
we're left with
6x+12=3x-30
step 3 add 30 to each side
12+30=42
now we have
6x+42=3x
step 4 subtract 6x from each side
3x-6x=-3x
now we have
-3x=42
step 5 divide each side by -3
42/-3=-14
so x = -14
now lets compare our steps to maya's
as we look at the steps we notice that she messes up on step 2
when distributing 3 to -10
she gets positive 30 but its supposed to be -30
so we can conclude that she mad a mistake from step 1 to step 2
therefore the second one is your answer
Find the measure of the given angles. Show work!!
Answer:
m∠A = 45⁰
m∠B = 75⁰
Step-by-step explanation:
Given question 4;
m∠A = x + 51
m∠B = 81 + x
m∠C = 60⁰
The value of the missing angles can be determined by the finding the value of x first;
m∠A + m∠B + m∠C = 180⁰ (sum of angles in a triangle)
(x + 51) + (81 + x) + 60⁰ = 180
(x + x) + (51 + 81 + 60) = 180
2x + 192 = 180
2x = 180 - 192
2x = -12
x = -12/2
x = -6
Thus, the values of the angles are calculated as follows;
m∠A = x + 51
= -6 + 51
= 45⁰
m∠B = 81 + x
= 81 - 6
= 75⁰

a large painting has a length of 18 inches and width of 12 inches. If each dimension is reduced by x inches to make the ratio of length to width 5 to 3, what is the value of x
Answer:
The value of x = 3.
Step-by-step explanation:
The ratio between length and width is given by:
[tex]\frac{L}{W}=\frac{5}{3}[/tex]
Where:
L represents the new length W represents the new widthNow, we know that each dimension is reduced by x inches, it means:
[tex]L=18-x[/tex]
[tex]W=12-x[/tex]
Then, we will have:
[tex]\frac{18-x}{12-x}=\frac{5}{3}[/tex]
Finally, we just need to solve it for x.
[tex]3(18-x)=5(12-x)[/tex]
[tex]5x-3x=60-54[/tex]
[tex]2x=6[/tex]
[tex]x=3[/tex]
Therefore, the value of x = 3.
