Answer: The graph is attached.
Step-by-step explanation:
1. Solve for y, as following:

2. The equation of the line in slope intercept form is:

Where m is the slope and b is the y-intercept.
3. In this case the equation of the line is:

then:

4. Find the x-intercept. Make y=0. Then:

5. Then, plot the line that passes through the points (0,7) and (4.9, 0).
6. The symbol of the inequality is < therefore, the line must be dashed and indicates that the region under the line must be shaded.
Then you obtain the graph attached.
Answer:
$48.96
Step-by-step explanation:
Given data
Length= 10inches
Width=14 inches
Let us find the perimeter of the certificate
P=2L+2W
P= 2*10+2*14
P=20+28
P= 48 inches
Hence if 1 inche cost $1.02
Then 48 inches will cost x
cross multiply we
x= 48*1.02
x= $48.96
Hence it will cost $48.96 to frame the certificate
Answer:
Maybe -12?
Step-by-step explanation:
Because sometimes variables on their own symbolize 1, so we can subtract 13 from 1 to get -12.
Answer:
4
Step-by-step explanation:
If ten people each get three slices, they will need 30 pieces.
10 x 3 = 30
Each pizza has 8 slices, so we divide 30 by 8 to get the number of pizzas needed.
30 / 8 = 3.75
You can't buy 3.75 pizzas, so you must get 4 to ensure everyone gets enough.
