Answer:
= -x^2 +x
Step-by-step explanation:
(x) = 1 - x^2
g(x) = 1-x,
(f-g)(x) = 1-x^2 - ( 1-x)
Distribute the minus sign
= 1-x^2 -1 +x
Combine like terms
= -x^2 +x
Answer: E. 40
Step-by-step explanation:
The x-intercept of a line is when the y coordinate is equal to zero, so input zero in for y and solve for x to find the x-intercept.
1/2x + 3/5(0) = 20
1/2x = 20
x = 40
Answer:
The product of 3 and a variable n plus 7
Step-by-step explanation:
So this is easy counting
so 5x^2-3x-9
we have 5 x^2's
-3 x's
-9
wat do we add to that to get
1 x^2's
-5 x's
+6
so we do each
5x^2+what=1x^2
subtract 5x^2
from both sides
what=-4x^2
first is -4x^2
then we have -3x to -5x
-3x+what=-5x
add 3x to both sides
what=-2x
second is -2x
-9 to 6
-9+ what=6
ad d9
what=15
last is 15
thereffor add -4x^2-2x+15
