Answer:
Step-by-step explanation:
f(x) = x + 7
g(x) = x^2 - 1
Part A: f(x^2 - 1) = x^2 - 1 + 7 = x^2 + 6
Part B: g(x+7) = (x + 7)^2 - 1 = x^2 + 14x + 49 - 1 = x^2 + 14x + 48
Answer:
18/18
Step-by-step explanation:
18 divided by 18 is one
Answer:
the first one is graph c and the second, graph b.
Step-by-step explanation:
They are both linear inequalities, so for both, you have to solve for x first. For the first one, since x is basically multiplied to 2 (2x), you have to divide both sides to get x by itself, and you get x>25. The graph has to have an opened circle, and the arrow should go to the right because all the numbers greater than 25 can be x. For the second one, you have to subtract 6 to both sides to get x by itself which then leaves you with ×<26. This one should also be an opened circle, and is going to the left, because all the numbers less than 26 can be x.
Hi, there.
For this question, we can apply the Pythagorean theorem .
I'm sure you've seen this equation before, and they kind of tried to trip you up with this problem. Trust me, it's easier than it looks. Let's break it down.
Lengths a and b both have the value of 48, which means that the value s in is 48, because the length of the hypotenuse is the same as the length and height squared multiplied by 2.
Plug in the value for c:
Plug in the value for s:
Do the innermost exponents first:
The square root symbol and the power of 2 cancel each other out, so we are left with:
s = , so the hypotenuse is 4608 inches.
