Let f(x) = x + 8 and g(x) = x2 - 6x - 7. Find f(g(2)).

OLga [1]

If you have double functions, solve the one in the parentheses first.

in f(g(2)), solve g(2) first.

So, substitute 2 in the function.

g(x) = x^2 - 6x - 7

g(2) = 2^2 - 6(2) - 7 = -15

If you substitute -15 in f(g(2)), it becomes f(-15).

f(x) = x + 8

f(-15) = -15 + 8

f(-15) = -7

The answer for f(g(2)) is -7.

What is the x and y intercept of each equation?

Talja [164]

The "x" intercept is where a line would mark across the "x" axis.

The "y" intercept is where a line would mark across the "y" axis.

X is horizontal and Y is vertical.

hram777 [196]

Answer:

For #9 it can be 4,6, or 7

#10 is angle 3

#11 is 134

#12 is 49

Step-by-step explanation:

#9 just look at the picture given and see which one is opposite from it

#10 look at which one is beside it but that the ’half‘ circles are facing each other

#11 and #12 subtract the angles they give you and see if they are next to each other and if they are that subtract the number they give you by 180-the degrees of a line

PLEASE HELP ME MI AMOR

PilotLPTM [1.2K]

Answer:

A: 5/18

B. 17/36

Step-by-step explanation:

ONLY COZ U CALLED ME "MI AMOR"

Event A: It is observed that there are 10 cases where the sum is greater than 8.

The cases are, (3,6), (4,5), (4,6), (5,4), (5,5), (5,6), (6,3), (6,4), (6,5), (6,6).

Thus, the probability for event A is $\frac{10}{36}=\frac{5}{18}.$

Event B: The sum is not divisible by 3 and not divisible by 5.

There are 17 where the sum is not divisible by 3 and not divisible by 5.

The cases are, (1,1), (1,3), (1,6), (2,2), (2,5), (2,6), (3,1), (3,4), (3,5), (4,3), (4,4), (5,2), (5,3), (5,6), (6,1), (6,2), (6,5).

Thus, the probability for event B is $\frac{17}{36}$ .

hope this helps:)
