Find the solutions to x2 = 24.<br> O A. x = +216<br> O B. x = 16.6<br> O C. x= 46<br> O D. x = +62

babymother [125]

Answer:

x =±2 sqrt(6)

Step-by-step explanation:

x^2 = 24

Take the square root of each side

sqrt(x^2) = sqrt(24)

x = ±sqrt(4*6)

x =±sqrt(4) sqrt(6)

Given f(x) = 10 -2xfind f(7). –4 3 7 56

strojnjashka [21]

Answer: $f(7)=-4$

Step-by-step explanation:

1. You have the following function given in the problem:

$f(x)=10-2x$

2. Then, to find $f(7)$ asked in the exercise, you only need to substitute $x=7$ (which is the input value) into the given function.

3. Therefore, keeping the above on mind, you obtain that $f(7)$ is:

$x=7$

$f(7)=10-2(7)$

$f(7)=10-14$

$f(7)=-4$
