Answer:
x^2+x-4
Step-by-step explanation:
(f-g)=(x^2+1)-(5-x)
=x^2+1-5+x
=x^2+x-4
Answer:
the slope increases
Step-by-step explanation:
Write a new equation using the new y-intercept and same slope as the original equation. Analysis: What effect does changing the y-intercept of an equation have on the graph? Increasing a y-intercepts moves the graph up. Decreasing a y-intercept moves the graph down.
Answer: 24
Step-by-step explanation: 180-114=66
66+90=156
180-156=24
Which sequence matches the recursive formula? an=2an-1+5, where a1=5. A) 5,10,15,20 B) 5,15,35,75. C)5,15,25,35. D) 5,20,35,40

The recursive formula

means that, to compute the next value, you have to double the previous one and then add 5.
So, we start with 5. To get the second term, we double it and add five, so we have

Next, we will double 15 and add 5:

So, the answer is B, because it's the only option starting with 5,15,35.
Just to check, let's compute the last step:

Which confirms option B
133 112
---- = -------
x 16
112x = 133 . 16
112x = 2128
x = 2128/112
x = 19
answer: x = 19
