Answer:
-7x + 24
Explanation:
(13x + 30) - (20x + 6)
13x + 30 - 20x - 6
-7x + 30 - 6
-7x + 24
Answer:
The answer is D
Step-by-step explanation:
Plug any x value for the y values of f(x) and g(x)
Let's do 0 since it is easier.
f(x)=-2(0)-4=-4
g(x)=-2(0)+2=2
So, g(x) is 6 greater than f(x).
Thus, g is most likely moved 6 units up from f.
Graph the 2 functions on Desmos for a better picture.
Step-by-step explanation:
but that is the easiest of all 4 questions (by far) :
3g(x) + h(x) = 3×(5x² + 3) + 9x² = 15x² + 9 + 9x² = 24x² + 9
which is exactly f(x) = 24x² + 9
so, yes, they are equal.
I really have to wonder, since you correctly solved 1-3, what was the issue with 4. ?
Answer:
1
Step-by-step explanation:
f(x)=x^3+2x^2-x-1
f(1)=1^3+2(1)^2-1-1
f(1)=1+2*1-1-1
f(1)=1+2-1-1=3-1-1=2-1=1
