Help me !?! I don’t get it

Answer:

11) x = 11

12) x = 11

Step-by-step explanation:

11) Δ RQP and Δ RLK are similar.

Hence, the ratios of the corresponding sides of the two triangles will be constant.

So, \frac{RK}{PR} = \frac{RL}{QR}

⇒ \frac{x - 4}{49} = \frac{11}{77}

⇒ \frac{x - 4}{49} = \frac{1}{7}

⇒ x - 4 = 7

⇒ x = 11 (Answer)

12) Δ QRS and Δ QDC are similar.

So, \frac{QD}{QR} = \frac{QC}{QS}

⇒ \frac{2x - 14}{32} = \frac{6}{24}

⇒ 2x - 14 = 8

⇒ 2x = 22

⇒ x = 11 (Answer)

3. Write an equation in slope-intercept form of the line that passes
kirill115 [55]

Answer:

B. y = 2x - 9

Step-by-step explanation:

All of the answer choices has a slope of 2, but B is the only answer choice that has (4,-1) on its line.

You can tell by plugging the point into the equation and seeing if the result is true.

y = 2x - 9

-1 = 2(4) - 9

-1 = 8 - 9

-1 = -1
