wariber [46]

Answer:

Option A. $x=10\ in$

Step-by-step explanation:

we know that

The combined area of the 3 windowpanes and frame is equal to

$(3x+12)(x+12)=924\\ \\3x^{2}+36x+ 12x+144=924\\ \\ 3x^{2}+48x-780=0$

using a graphing tool to solve the quadratic equation

The solution is $x=10\ in$

Hello! :)

Step-by-step explanation:

$Slope=\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN}$

$\frac{3-4}{3-0}=\frac{-1}{3}=-\frac{1}{3}$

Therefore, the slope is -1/3.

-1/3 is the final answer.

Hope this helps!

Have a nice day! :)

Answer:

(3) y = (x -3)²

Step-by-step explanation:

Try the first value of x in each function:

(1) y = 3² -3 ≠ 0

(2) y = (3 +3)² ≠ 0

(3) y = (3 -3)² = 0 . . . . . . matches the table value for f(3)

(4) y = 3² +3 ≠ 0

The only viable choice is (3).
