( 2x − 27 ) ( −x + 15 )
= ( 2x + −27 ) ( −x + 15 )
= ( 2x ) ( −x ) + ( 2x ) ( 15 ) + ( −27 ) ( −x ) + ( −27 ) ( 15 )
= −2x^2 + 30x + 27x − 405
= −2x^2 + 57x − 405
When solving the slope you have to do this formula

The answer is -4/-5
Answer:
f(-1) = 6
Step-by-step explanation:
f(x) = x + 7 when x = -1
~Substitute
= (-1) + 7
~Simplify
= 6
Best of Luck!
Slope intercept form is y = -2x + 14
Step-by-step explanation:
- Step 1: The original equation is 4x + 2y = 14.
- Step 2: Rearrange so that x is first in the right hand side of the equation.
⇒ 2y = - 4x + 14
- Step 3: Subtract 4x from both sides of the equation.
⇒ 2y = 14 - 4x
- Step 4: Divide both sides of the equation by 2 so that coefficient of y is 1.
⇒ y = - 2x + 7
This is the slope intercept form y = mx + b
