F(x) = -1 g(x) = x-4 Can you evaluate (gof)(o)? Explain why or why not.

1 answer:

7 0

Answer: Yes. (gof)(0) = -5

(gof)(0) means you will find the function of g(f(0)), which means we will find f(0) and plug that value in for x in the function g(x)

We know f(0) is -1, so we can plug -1 into the equation of g(x)

(gof)(0) = (-1) - 4
(gof)(0) = -5

How do you do this?????

$y = 2x - 9$

Step-by-step explanation:

Let's rewrite the given equation such that only y is on the left side and everything else on the right side:

$3x + 6y = -30 \Rightarrow 6y = -3x - 30$

Simplifying this by dividing by 6, we get

$y = -\frac{1}{2}x - 5$

This line has a slope of -1/2, which means that a line perpendicular to this has a slope of 2 (i.e., negative reciprocal). So we can write its equation as

$y = 2x + b$

This is the slope-intercept form of the equation of the line perpendicular to our given line. To complete this form, we need to find the value of b. Since this line passes through (1, -7), put these numbers into our equation to get

$-7 = 2(1) + b \Rightarrow b = -9$

Therefore, the slope-intercept form of the equation can be written as

$y = 2x - 9$

How do I do this as I need help but don’t know how to solve it ??

Answer: 14 tickets weren't sold.

Step-by-step explanation:

14 times 15 = 210

So there are 210 seats in the cinema.

The total is $1274 so you would divide

$6.50\sqrt{1274 \\$ which equals 196

Your final step is to subtract

210 (the total seats) minis 196 (seats sold) equals 14 seats not sold

HOPE THIS HELPED!!!!

Use the table to predict the number of times you will spin 3 when you spin the spinner 100 times. Spinning a Spinner Number spun

Naily [24]

Step-by-step explanation:

I am not sure i understand the text you put there.

what I think is clear is to find the expected number of the appearances of the number 3 when spinning the spinner 100 times.

to do this we start by checking the given information.

and we see that the given table based on the result of in total 50 spins (7+8+9+7+11+8).

when spinning the spinner additional times, we can expect the same structure of distribution of the individual possible results as before. we just scale everything to the new size of the overall sample.

before, with 50 spins, we saw the number 3 9 times.

so, with 100 spins, which is 2×50, we expect to see the number 3 then 2×9 = 18 times.
