Answer:

Step-by-step explanation:
We have the equation
.
The ordered pairs of this equation have the form 
Where x is the independent variable and y is the dependent variabe.
That is, the points belonging to the line
have the form 
For
.
So, we need to find
for x_0 = -3.
Then we substitute x = -3 into the equation and clear the value of y.

.
Then the ordered pair is:

Answer:
80%
Step-by-step explanation:
Percent increase is calculated as
× 100%
Increase = $27 - $15 = $12 , then
percent increase =
× 100% = 0.8 × 100% = 80%
Answer: where is them model
Step-by-step explanation:
Answer:
= 2.8
Step-by-step explanation:
If the quadrilaterals are similar, then the ratios of corresponding sides will be equal:
KL : QR = 4 : 5.6 = 4 / 5.6 = 5/7
JM : PS = 7 : 9.8 = 7 / 9.8 = 5/7
LM : RS = 3 : 4.2 = 3 / 4.2 = 5/7
This shows that the ratio of KJ : QP = 5/7
KJ : QP = 2 :
= 2 / 
Therefore, 
cross multiply: 14 = 5
Divide both sides by 5:
= 2.8
