What is the missing variable?​

Mathematics
1 answer:
zhuklara [117]3 years ago
5 0

Answer:

137°

Step-by-step explanation:

So, both are equal to each other due to them being the same degree angle.

5x + 7 = 8x - 71

subtract 5x on both sides

7 = 3x - 71

add 71 to both sides

7 + 71 = 3x - 71 + 71

78=3x

divide both sides by 3

78/3 = x

x = 26

insert x into the equations

5(26)+7°

= 137°

8(26)-71°

= 37°

If f(x) = - x + 4 and g(x) = x ^ 2 - 5 , then f(g(-2))=?
kkurt [141]

Answer:

Step-by-step explanation:

using your f(x) I want to show you how to plug in different things itnot he function.

f(x) = -x + 4

f(1) = -1 + 4 = 3

f(2) = -2 + 4 = 2

f(m) = -m + 4

f(abc) = -(abc) + 4

f(h(x)) = -h(x) + 4

Does that help?  what if you replaced h(x) with g(x)?  Of course you already have that x so you could make it a little simpler as well.  Let me know if you don't quite get it.
