Answer:

x = 5

Step-by-step explanation:

Since ∠P ≅ ∠P and ∠PST≅ ∠PRQ (corresponding angles are congruent when the lines are parallel), ΔPST is similar to ΔPRQ by the AA postulate

Therefore, corresponding sides are in proportion.

PS ↔ PR and ST ↔ RQ

$\frac{PS}{PR} = \frac{ST}{RQ} \\\frac{x + 7}{2x + 6} = \frac{6}{8}$ Note: PR = PS + SR = x + 7 + x - 1 = 2x + 6

8(x + 7) = 6(2x + 6)

8x+56 = 12x + 36

4x = 20

x = 5

Answer:

Graph of Option D represents $y=\sqrt{x}$

Step-by-step explanation:

we are given our function as

$y=\sqrt{x}$

squaring on both sides we get

$y^2=x$

It represent a parabola opening towards the positive side of x axis. Hence it gives us some preliminary idea about the graph of the function we are given .

However our original function is $y=\sqrt{x}$

Domain of $y=\sqrt{x}$ is all positive values of x

And square root of positive values will always result in positive values. Hence y can not be negative as the range is All positive values of y

Hence we erase the graph of $y^2=x$ below x axis to obtain the graph of

$y=\sqrt{x}$
