Answer:

Option E x=x^2-10x+21

Step-by-step explanation:

we have

x-5=\sqrt{x+4}

we know that

For x> 5 both sides of the equation will be positive

Squared both sides

(x-5)^2=(\sqrt{x+4})^2

(x-5)^2=(x+4)

x^2-10x+25=(x+4)

Subtract 4 both sides

x^2-10x+25-4=(x+4)-4

x^2-10x+21=x

Rewrite

x=x^2-10x+21

A farm stand sold 12 ears of corn for 4$ .the farm stand sold 180 ears of corn at the same rate
oksano4ka [1.4K]
To answer this first we set up a proportion and then solve. Lets do it:-

\frac{4}{12}= \frac{x}{80}

Cross Multiply:-

80 · 4 = 320

Divide:-

420 ÷ 12 = 60

So, 180 ears of corn are for $60.

Hope I helped ya!!

Answer:

3) all \: real \: numbers, (  - \infty , \infty ), or -  \infty  \leqslant x \leqslant  \infty (same thing)

4) -  \infty  < y < 0 or ( -  \infty ,0) (same thing)

5) -2 or (0, -2) (same thing)

Step-by-step explanation:

3) Domain represents the amount of x-values in a function. The image shows that the function's arrows point in both directions (right and left), infinitely, so the domain would be all \: real \: numbers, (  - \infty , \infty ), or -  \infty  \leqslant x \leqslant  \infty(same thing).

4) Range represents the amount of y-values in a function. The function goes downward forever (- \infty  < y) by the indication of an arrow and halts just under the y-axis (y < 0). After combining these two inequalities, you see that the range is -  \infty  < y < 0 or ( -  \infty ,0) (same thing).

5) The y-intercept is where the function crosses the y-axis. In this function, the y-intercept is -2 or (0, -2) (same thing).
