It states reflected over the y-axis, so treat the y axis as a mirror and you will realise that the x is always the inverse number. For example, if it is -2, the reflected value will be 2. (y remains unchanged)
X: (10,2)
Y: (8,-7)
Z: (-9,5)

Solve the system by substitution.
y=-x
-2x+5y=-28
Answer:
(4,-4)
x=4
y= -4
Step-by-step explanation:
We know that y is equal to and so we can plug the y value in for x into the other equation
-2x+5(-x)= -28
Solve for x
-2x-5x= -28
-7x= -28
x=4
Now that we know that x= -4 we can plug this into one of the two starting equations and solve for y
y= -(4)
y= -4
Which of the following is NOT an arithmetic sequence?
a
1, 2, 3, 4,...
b
0.25, 0.5, 0.75, 1, ...
c
2, 2.5, 3, 3.5,...
d
-2, 4, -6, 8,...
Answer:
D
Step-by-step explanation:
To be an arithmetic sequence, the numbers have to be added or subtracted by a constant number. D is not the answer because -2+6 equals 4, but 4+6 doesn't equal -6, so D cannot be a arithmetic sequence.

Check:
x=3
3*3+2=11*2=22
7*3+10=31*2=62
62+22=84
20*3+24=84
Answer:
B.) 3x+2
Step-by-step explanation:
2(7x+10)+2y=20x+24
14x+20+(6x+4)=20x+24 because there are two sides where you have to
20x+14 multiply the height and width by two o account for
both the actual number before multiplied was 3x+2
x= 1 /3 y+ −2/ 3
x=3y+2

Jayla is a salesperson. She sold a guitar for $96 and earned 20% commission. How much
commission did jayla earn
Answer:
$115.20
Step-by-step explanation:
Hi! We need to find 1% of 96 to multiply by 20.
96 / 100 = .96
Now we multiply by 20.
20 x .96 = 19.2.
Now, we add 19.2 to what she earned in the first place (96).
19.2 + 96 = 115.20
