Rebecca is a Texas resident and she plans to attend Texas Tech for all 4 years of college. She has a yearly scholarship of $10,0

andrezito [222]

Answer:

To complete the required $m dollars for her college, she needs $(m - 60,000).

Step-by-step explanation:

Suppose Rebecca needs $m to complete her college education,

because she has a yearly scholarship of $10,000, she would have $10,000 × 4 = $40,000 for the four years she would spend in college.

Together with her savings of $20,000, she has $20,000 + $40,000 = $60,000 in total.

Therefore to complete the required $m dollars for her college, she needs $(m - 60,000).

Find the domain of f(x). f(x) = √9x+36

horsena [70]

Answer:

The domain in interval notation is [-4,∝) or set build: {x|x $\geq$

Step-by-step explanation:

I'm assuming the 9x and the 36 are in the root

$\sqrt{9x+36}$

first we must solve for x

${9x+36}\geq 0$

substract 36 to both sides

${9x}\geq -36$

divide by 9 to both sides

$\frac{9x}{9} }\geq \frac{-36}{9}$

simplify left side

$x\geq \frac{-36}{9}$

simplfy right side

$x\geq -4$

The domain in interval notation is [-4,∝) or set build: {x|x $\geq$ -4}
