Answer:
Step-by-step explanation:
To factor an expression you have to first find the highest common factor (HCF) of the numbers in the expression. You divide them by their HCF, bracket it and place the HCF outside the bracket.
To check if it is factored properly you can do the opposite of what you just did by clearing the bracket.
9 (7 + 9)
(9 x 7) + (9 x 9)
= 63 + 81
Answer: First Option (2,-7)
Step-by-step explanation:
We have a system of equations formed by the following equations:
To answer this question we must solve the system of equations. There are several ways to solve it. The easiest way to solve it for this case is to multiply the second equation by -1 and then add it to the first equation.
----------------------
Now substitute x = 2 in any of the system equations and solve for y.
Therefore the solution of the system is the point: (2, -7)
