c. Laptop (1.08 x 299.99)
d. Video Game (1.04 x 39.95)
In which step did the student first make an error?
Answer: Step 2
Step 2 should be:
−3y = -45 + 6z
Answer: -54
Step-by-step explanation:
Answer:
D.
Step-by-step explanation:
To see if a line is parallel to y = -(2/3)x + 8 you need to check if the coefficients at y and x are of the same ratio. This immediately removes answers A and C, because of the wrong sign at x compared to y.
What's left is to see which of the answers B and D passes through (4, -5) by inputting x = 4 and y = -5
B.
left = -5 - 5 = -10
right = -(2/3)(4 + 4) = -16/3
So it's D. Let's verify:
D.
left = -5 + 5 = 0
right = -(2/3)(4 - 4) = 0
Checks out.
