Answer:
h(x) = 2x - 8
Step-by-step explanation:
Step 1: Define
f(x) = -2x
g(x) = 4x - 8
h(x) = f(x) + g(x)
Step 2: Find h(x)
h(x) = -2x + 4x - 8
h(x) = 2x - 8
Answer:
10
Step-by-step explanation:
If we plug in any negative number as x, the result will always be greater than 4, which rules out answers A and B
lets try plugging in 4 as x to test answer C:
2(8-4)
2(4)= 8
8 is greater than 4, therefore C is wrong.
Lets try 10 as X (answer D):
2(8-10)
2(-2)
-4
We know that -4 is less than 4, therefore it makes the inequality true! :)
Answer:
The first one would be 30.
Step-by-step explanation:
First you multiply the 8 x 4, because the 4 and P are multiplying you just substitute the variable, and then substract 2.
Answer:
they are equidistant from the origin
Step-by-step explanation:
when the 2 points are swung around the origin they must stay the same distance away from the origin meaning that option a is correct
Answer:
k=f(x)+2x+2
Step-by-step explanation:
f(x)=-2x-2+k
-2x-2=f(x)-k
f(x)-(-2x-2)=k
f(x)+2x+2=k
