13. No
14. No
15. Yes; Domain: (-4,3) Range: (-4)
Answer:
The slope:

Step-by-step explanation:
-To determine the slope of the following points shown, you need this formula:

(
represents the slope,
represents the first coordinate and
represents the second coordinate)
-Apply the following points to the formula:

Then, solve:


So, the slope is
.
Answer:
m<−18
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
m+12<−6
Step 2: Subtract 12 from both sides.
m+12−12<−6−12
m<−18
Answer:
481 whole miles
Step-by-step explanation:
Total cost would be 3 x 24.95 + 0.26m, where m is the miles driven.
Total cost has to be under or equal to $200, so
3 x 24.95 + 0.26m <= 200
74.85 + 0.26m <= 200 ( 3 x 24.95)
0.26m <= 125.15 ( subtract 74.85)
m <= 481.35 ( divide 0.26)
We are given two points of a line
(-2, -2) and (1,4)
Equation of line:
Firstly , we will find slope
(-2, -2) and (1,4)



now, we can find equation of line

now, we can plug values
and we get


Distance:
now, we can use distance formula

firstly , we will find a and b
a=2 and b=-1
point is (6,-1)
so, xo=6 and yo=-1
we can plug values
and we get
