Answer:

B

Step-by-step explanation:

The zeros are where the function crosses the x-axis. In this case, it is 5/2 and -3, which eliminates options C and D. Next, the y-intercept is the point as to where the function crosses the y-axis. Here, it is (0,15), but does not help us to narrow down our options. Finally, the maximum is the highest y-value that the function touches. If you observe the graph at its highest point, it can be inferred that it's y-value is slightly above 15, and so it is at 15.1 (x-value has no importance in this context).

Help me !?! I don’t get it
emmasim [6.3K]

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)
