Ok here it is:
4x-5y=40
2x+10y=20
I used the second equation and decided to get x
2x+10y=20
Subtract 10y from both sides.
2x=-10y+20
Divide both sides by 2
x=-5y+10
Put that in for x for first equation
4(-5y+10)-5y=40
Distribute the 4
-20y+40 -5y =40
Combine like terms
-25y+40=40
Subtract 40 from both sides
-25y=0
Divide by -25 on both sides
y=0
Substitute the y in for the 2nd equation
2x+10(0)=20
2x=20
Divide both sides by 2
x=10
So x=10 and y=0
Answer:
The answer is 4a+20....
Step-by-step explanation:
Use the distributive property.
According to which when using the distributive property, you have to distribute (multiply) the 4 to the a and then the 4 to the 5. It looks like this.
4(a+5)
4(a)= 4a
4(5)=20
Thus the expression becomes:
4a+20
Thus the answer is 4a+20....

Answer:
Part a) 
, 
Part b) The graph of the reduced image in the attached figure
Step-by-step explanation:
Let
z-----> the scale factor
x----> the length side of the reduced image
y----> the length side of the original image
so
----> equation to find the length side of the reduce image
we have
Part a) Calculate the length of each side of the reduced image
Part b) Draw the new image and label it
I assume that AB is the length of the original rectangle and AC is the width of the original rectangle
Using a graphing tool
see the attached figure
