Answer:

Step-by-step explanation:

f(-2) means you want to find the y value when x=-2. Plug in x=-2 into the f(x) equation to get: [-3(-2)]-2 = 6-2 = 4.

so f(-2)=4

But the question asks for f(-2)+9. So you add 9 to f(-2) which is 9+4 = 13

Please solve and i’ll give u brainliest

Usimov [2.4K]

Solution:

Note that:

Given angles: w + 8° and 48°
w + 8 + 48 = 180

Solve for w in the equation "w + 8 + 48 = 180".

=> w + 8 + 48 = 180
=> 56 + w = 180
=> w = 180 - 56
=> w = 124°

The value of w is 124.
