Answer: C
Steps: 4x + y = -4, x + y = 2
Isolate the x for (x + y = 2): x = 2 - y
Plug the value of x into the other equation: 4(2 - y) + y = -4
Simplify: -4y + 8 + y = -4
Combine like variables (letters): -4y + y = -3y
So -3y + 8 = -4
Subtract eight from both sides: -3y + 8 - 8 = -4 - 8
-3y = -12
Divide both sides by negative three: -3y ÷ -3 = -12 ÷ -3
Simplify: y = 4
Plug the value of y into one of the original equations (I'll use x + y = 2):
So x + 4 = 2
Isolate the x variable: x = -2
Division property of equality because you divide the same by the same number on both sides of the equation
It has a 31% chance. i used a calculator. so i guess the best answer is B.
Just do what you would do if you multiply double digit numbers expect with an extra digit. then count how many numbers are behind the decimal and when your down put the decimal point as much to the left from how many numbers are originally behind the decimal.
Answer:
4(a-1)(a-2)
Step-by-step explanation:
take out 4 (common factor)
4(a^2-3a+2)
then use box method to factor
<u> a -1</u>
a<u> a^2 -a</u>
<u>-</u>2<u> -2a 2</u>
4(a-1)(a-2)
