Answer
x= -7, -1
Step-by-step explanation:
x^2= -7x- 8
x^2+ 7x+ 8 =0
x+7=0 x+1=0
x=-7 x=-1
Step-by-step explanation:
3x+2y=22
5x-2y=42
by adding both equation
8x. =64
x=64/8=8
substituting x in the 1st equation
we get,
3*8+2y=22
24+2y=22
2y=22-24
y=-2/2=-1
therefore,
x=8
y=-1
Answer:
21x - 42, see below :)
Step-by-step explanation:
Hello!
We know that f(x) is equal to 3x - 6
We want to know what 7 * f(x) is so we should first substitute f(x) for 3x - 6
7 * f(x)
7(3x-6)
We use distributive property to open the parenthesis:
7 * 3x + 7 * -6
21x - 42
