Answer:
g(f(x))=(−3x+7)2−8 (a. -55/7)
Step-by-step explanation:
f(x)=−3x+7g(x)=x2−8g(f(x))=(−3x+7)2−8
and i like you pfp! Hope i helped if wrong tell me.

First, I’m going to the line is question into slope intercept form.
y + 10 = -5x + 5
y = -5x + 5 -10
y = -5x -5
y + 10 = -5 (x - 1) becomes y = -5x -5 in slope intercept form. I will call this line ‘line 1’
A becomes y = 5x -15 in slope intercept form
B becomes y = -5x + 25 in slope intercept form
C becomes y = -5x -5 in slope intercept form
D becomes y = -5x + 10 in slope intercept form
C is the same line as line 1. Any point that is on line 1 is also on line C, so C cannot be it.
Notice that line B and D have the same slope but different y-intercepts as line 1. That means these lines are parallel (not the same line though - different y intercepts) to line 1, so they will never intercept.
Line A has a different slope vs line 1, so they will eventually intersect only once
Answer:
77/200
Step-by-step explanation:
B is the correct answer because 32*4+34=162 which is half of the boys and 162*2=324 so there are 324 boys and 32 girls
Answer: 0.76
Step-by-step explanation:
We know that the sample proportion is the best estimate of the population proportion. (1)
Given : Gallup reported that of the 1,005 people surveyed, 76% of U.S. workers believe that they will continue working past retirement age.
Let p be the population proportion.
We have sample proportion:
Therefore, the estimated proportion of U.S. workers believe that they will continue working past retirement age from the sample =
