Answer: 1=x
Step-by-step explanation:
34-7x=15+12x
Add 7x to both sides of equation because the oppisite of -7x is +7x
34-7x+7x=15+12x+7x
34=15+19x
Subtract 15 from both side of equation because the oppisite of 15 is -15
34-15=15-15+19x
19=19x
Divide both sides by 19 to get x alone
19/19=19x/19
1=x
Answer:
D. They have the same slope ( rate of change) and the same y-intercept.
Step-by-step explanation:
I y = 1.2x + 0.4.
II The slope is (10-4)/(8-3) = 6/5= 1.2.
Its equation is
y - 4 = (1.2)(x - 3)
y = 1.2x - 3.6 + 4
y = 1.2x + 0.4.
Theres 2 solutions.........
Answer:
79/9 or 8.4 or 8 4/9
Step-by-step explanation:
Answer:
y = (2/9)(x + 1)² + 2
Step-by-step explanation:
y = a(x - (-1))² + 2
y = a(x + 1)² + 2
4 = a(2 + 1)² + 2
4 = 9a + 2
9a = 2
a = 2/9
y = (2/9)(x + 1)² + 2
