Answer:
A
Step-by-step explanation:
Given the 2 equations
y = x + 3 → (1)
y = 8x - 4 → (2)
Substitute y = 8x - 4 into (1)
8x - 4 = x + 3 ( subtract x from both sides )
7x - 4 = 3 ( add 4 to both sides )
7x = 7 ( divide both sides by 7 )
x = 1
Substitute x = 1 into either of the 2 equations for corresponding value of y
Substituting into (1)
y = 1 + 3 = 4
solution is (1, 4 ) → A

Answer:
$88.75
Step-by-step explanation:
since he bought two tickets for $25.5 each you have to do 2(25.50) and since he also spent $10 and $27.75 you have to add that as well.
y=2(25.50)+10+27.75
y=51+10+27.75
y=61+27.75
y=88.75
Answer:G
Step-by-step explanation:
4/9 times 2/8= 1/9
Vertex angle = x
1 base angle = 1/2x - 8
180-x = (1/2x-8)x2
180-x = x-16
196-x = x
196 = 2x
x=98

Easy, using
to find the intercept:
=
=3
This is your slope. m=3
To find y=mx+b form
-4=3(-1)+b
-4=-3+b
-1=b
y=3x-1 in y=mx+b form
