Direct Variation: If y = 12, when x = 4, find y when x = 20. a.40 b.48 c.12 d.60

d

Step-by-step explanation:

Given the x and y are in direct variation then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 12 when x = 4, that is

12 = 4k ( divide both sides by 4 )

3 = k

y = 3k ← equation of variation

When x = 20 , then

y = 3 × 20 = 60 → d

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.
