Answer: C

Step-by-step explanation:

(fog)(3) is the same as finding f(g(3)). To solve, we first need to solve g(3). then, we solve for f(g(3)).

g(3)=5(3) [multiply]

g(3)=15

Now, we plug in 15 into f(x).

f(g(3))=-2(15)+8 [multiply]

f(g(3))=-30+8 [add]

f(g(3))=-22

Now, we know that C is the correct answer.

-BARSIC- [3]

Answer:

A. 13

Step-by-step explanation:

Note: It seems typo in the question. 5% should read 59.

Let 3 credit courses = x, 4 credit courses = y

As per given we have following equations:

x + y = 18
3x + 4y = 59

Solve the system by elimination. Multiply the first equation by 4 and subtract the second one:

4(x + y) - (3x + 4y) = 4(18) - 59
4x + 4y - 3x - 4y = 72 - 59
x = 13

The answer is 13

Correct choice is A

A small explanation would be really appreciated

Step-by-step explanation:

the 2 angles marked with orange and green are equal becos the question said that the indicated angles are congruent meaning same deg. so 180 - that given angle = the 2 marked angles (based on the rule known as angles on a str line are supplementary)

since the 2 marked angles are same, you can say that d and k are parallel due to the rule of alternate angles
