Answer:

J. y = -1/2x + 3

Step-by-step explanation:

The y intercept is 3 & the slope is -1/2. For the slope, you have to go up 2, then left 4. Since it's -2/4, you can simplify that by 2, & get -1/2 as your slope. For your y-intercept, it's 3 because that's where the line begins/starts.

Clara is growing her hair out and wants it to be no longer than 15 cm but more than 11 cm. Her hair is 7 cm right now and grows
DedPeter [7]

Answer:

16, 32

Step-by-step explanation:

We need to solve for t in this compound inequality. Let's do that!

11 < 7 + 0.25t ≤ 15

4 < 0.25t ≤ 8

16 < t ≤ 32

Therefore, we know that it will take Clara more than 16 weeks and up to and including 32 weeks to grow out her hair.

Answer:

The correct option is 1 and 4 are correct.

Step-by-step explanation:

The dilation is the enlargement and comparison of a figure according to the scale factor from the given center of dilation.

The rule DO,2(x,y)(2x,2y) express the dilation with factor 2 and the center of dilation is origin. It shows the enlargement of the triangle. The sides of image is twice of the preimage.

In dilation the corresponding angles remains same and the corresponding sides are equal.

\angle P=\angle P'

\angle PQR=\angle Q'

\angle R=\angle P'QQ'

PR=P'Q

PQ=P'Q'

RQ=QQ'

Therefore option 1 and 4 are correct.
