Answer:

Step-by-step explanation:
step 1
Determine the slope of the dashed line
The formula to calculate the slope between two points is equal to

we have
(-3,1) and (0,3)
substitute


step 2
Find the equation of the dashed line in slope intercept form

we have

---> given problem
substitute

step 3
Find the equation of the inequality
we know that
Is a dashed line and everything to the left of the line is shaded
so

see the attached figure to better understand the problem
F =

c + 32 Subtract 32 from both sides
F - 32 =

c Mutliply both sides by <span>

to cancel out the fraction
</span>

F - 17

= c Switch the sides to make it easier to read
c =
F - 17 <span>
</span>
C= 3
1. divide 39 by 13= 3
2. then plug 3 in
3. 13 (3)=39
4. and it makes sense.....:-)
Answer: 18 in.
Step-by-step explanation:
the formula for perimeter is A=2l+2w
Since 0.5ft is 6 inches and you have to multiply it by 2 you will get 12 inches
3 in x 2 is 6 inches
Then you add your products === 12+6
And you get 18 in.
