Answer:

Step-by-step explanation:
-5x - 10y = 15
<u>-3x + 10y = 25 </u>+
-8x = 40

x = -5
.
Substitute the value of x to one of equations
-5(-5) - 10y = 15
25 - 10y = 15
-10y = 15 - 25
-10y = -10

y = 1
You look for two good points on the graph, then you rise and run.( go up then move right or left)
Answer:
The correct option is D.
Step-by-step explanation:
It is given that Issouf claims that the scale factor is 1/2.
From the given figure it is clear that

Answer:
the cost each of one cherry pie and one lemon meringue pie is 9 and $12 respectively
Step-by-step explanation:
The computation of the cost of one cherry pie and the lemon meringue pie is shown below:
Let us assume the cherry pie be x
And, the lemon meringue pie be y
So according to the question
x + 5y = $69
5x + 7y = $129
Now multiply by 5 in the equation 1
5x + 25y = $345
5x + 7y = $129
18y = $216
y = $12
And, x would be
x + 5($12) = $69
x = $9
Hence, the cost each of one cherry pie and one lemon meringue pie is 9 and $12 respectively
The graph moves 8 units to the right.
