2y-7>15
2y> 15+7
2Y > 22
2Y/2>22/2
y > 11
put any number below 11 in the left side it will be less then 15


2x-5> 1
2x > 1 +5
2x > 6
2x/2 > 6/2
x > = 3
put 3 instead of x in the left side it will be equal to the right side or put anything less then 3 then the left side will be less then 1

2x+5>1
2x > 1-5
2x > -4
2x/2>-4/2

x> -2

put -2 instead of x it will be equal to the right side anything less then -2 then it will be less the the right side

What is the average rate of change from x = 0 to x = −2?
Sergio039 [100]
<h3>Answer is    -3</h3>

How I got that answer:

The graph shows the two points (0,-4) and (-2,2) are on the parabola. The x coordinates of both points are from x = 0 and x = -2 as given in the instructions. Compute the slope of the line through those points. The slope of this line is the exact same as the average rate of change from x = -2 to x = 0.

m = (y2 - y1)/(x2 - x1)

m = (2 - (-4))/(-2-0)

m = (2 + 4)/(-2-0)

m = 6/(-2)

m = -3

A negative slope means the line slopes downhill as you move from left to right. This is a negative average rate of change.

Suppose you start an annuity where you invest $2,000 at the beginning of each year and 4% interest is paid at the end of the yea
olga55 [171]

Answer:

$10,400

Step-by-step explanation:

If 2,000 dollars are being invested at the beginning of each year and gets a 4% interest at the end that means 2,000*104%=$2,080

It also continues on for 5 years so 2,080*5=$10,400

30 points! would really appreciate the help!
katrin2010 [14]

Answer:

Step-by-step explanation:

cos43=60/AC

AC=60/cos43=82.04

cos27=60/BC

BC=60/cos27=67.34

sin(90-43)/BC=sin(43+27)/AB

AB=BCsin70/sin47

AB=67.34sin70/sin47

AB=86.522

P=86.522+67.34+82.04

P=235.9m
