5^20= 9.5367432e+13
4^13= 67108864
Use the y value in equation one and substitute it in equation two.
y=4x-3
y=-x-13
4x-3=-x-13
solve for x
add x to both sides
5x-3=-13
add 3 to both sides
5x=-10
divide both sides by 5
x=-2
Use x=-2 to solve for y in either equation
y=4x-3
y=4(-2)-3
y=-8-3
y=-11
(x, y) = (-2, -11)
Top right is the answer
Hope this helps! :)
So you multiply because you want to find out the cost of the total amount of apples per pound bought. You multiply 3 and 1.75 and you should get $5.25 for red apples. You multiply 4.2 pounds and 1.75 and you should get $7.35 for green apples.
The system of equation that will represent her purchase is as follows:
1.39b + 2.49m = 50.73
1.29b + 2.69m = 51.63
<h3>How to represent system of equation?</h3>
At store A she will pay a total sum of $50.73 for bread and milk.
At store B she will pay a total sum of $51.63 for bread and milk.
Therefore, the system of equation that will represent her purchase is as follows:
where
b = number of bread
m = number of milk
Therefore,
1.39b + 2.49m = 50.73
1.29b + 2.69m = 51.63
