Let f(x) = x2 - 8x 5. Find f(-1).
Ymorist [56]
In the equation you have to replace all x's with -1

f (-1) = (-1)^2 - 8(-1) +5
f (-1) =  1 + 8 + 5
f (-1) = 14

the f(-1) stand for the function of -1. it is also equivalent to y

How do u solve 4(3x-1)=9-x
Nastasia [14]

Answer:

x = 1

Step-by-step explanation:

Well the first step is to apply the distributive property:

4(3x - 1) is equal to (12x - 4). You DISTRIBUTE a '4' to what is inside the parentheses.

And btw, to make it easier, you can make 9 - x so that x is first. For example, (-x + 9). They're both the same thing, just written differently.

Your new equation is 12x - 4 = -x + 9. You want to now solve the equation.

Add the (-x) to both sides. It cancels out on the right side and you add it to 12x on the left side.

[If there's no number in front of a variable, you can always just put 1 in order to make it easier]

12x + 1x = 13x. Your new equation is 13x - 4 = 9. This should look very familiar. You simply add 4 to both sides. 9 + 4 = 13

Finally, 13x = 13. Divide 13 ÷ 13 to get 1.

x = 1
