Step-by-step explanation:

x² + 10x + 24 = 0

∆ = 10² - 4.1.24

∆ = 100 - 96

∆ = 4

$x' = \frac{- 10 + 2}{2} \\\\\ x' = - 4 \\\ x" = \frac{- 10 - 2}{2} \\\\\ x" = - 6$

To solve this system of equations using substitution, what could be substituted in place of y in the first equation? 4x = 5 − 2y

erik [133]

Answer:

y = $-\frac{4x-5}{2}$

Step-by-step explanation:

Step 1: Switch sides

5 - 2y = 4x

Step 2: Subtract 5 from both sides

5 - 2y - 5 = 4x - 5

Step 3: Simplify

-2y = 4x - 5

Step 4: Divide both sides by -2

$\frac{-2y}{-2} = \frac{4x}{-2} - \frac{5}{-2}$

Step 5: Simplify

y = $-\frac{4x-5}{2}$

What is the inverse of the function f(x) = 1/4x - 12?

madam [21]

Hello,

y=1/4 x-12
x=1/4 y -12 (exchange x and y)
1/4y=x+12
y=4(x+12) solve for y
y=4x+48
