Answer:
(-1, 3)
Step-by-step explanation:
In order for a point to be a solution to a system of equations, the lines have to intersect at that point in the graph. We can see that the two lines at the graph intersect at (-1,3), so that must be the solution.
Answer:
4(7y-8)
Step-by-step explanation:
When you multiply a base with an exponent by a base with an exponent, you add the exponents together. (But you can only combine the exponents when the bases are the same)
For example:
(they have the same base of x)
(you can't combine the exponents because they have different bases of y and x)
When you have a negative exponent, you move the base with the negative exponent to the other side of the fraction to make the exponent positive.
For example:
or
or
Add the exponents together
Make the exponent positive
