Answer:
(x - 2) and (x + 3) is a factor of: 2x² + 2x - 12
Step-by-step explanation:
2x² + 2x - 12 given equation
Now divide it by 2 we get,
x² + x - 6
then
x² + x - 6
x² + 3x - 2x - 6
x(x + 3) - 2(x + 3)
<em><u>(x - 2) (x + 3)</u></em>
<span>x= -8 + y
-9x + 6y= 9
substitute </span>x= -8 + y into -9x + 6y= 9
-9x + 6y= 9
-9(-8 + y) + 6y= 9
72 - 9y + 6y = 9
-3y = -63
y = 21
<span>x= -8 + y
</span><span>x= -8 + 21
x = 13
solution (13, 21)</span>
The answer would be An = -1.3n + -3.7
2x+7x= 180
9x=180
x=20
Plug the x value in to both expressions
2(20)=40
7(20)=140
Final answer: 40 degrees, 140 degrees
To find the number you can set up a small equation (x being the number) and solve for x.
It can be written as 2 ( x + 4) < 12
Solve for x to find the number.
2 ( x + 4) < 12
Distribute the 2
2x+8<12
Subtract 8 on both sides
2x<4
Divide by 2 on both sides
x<2
Therefore the number is any number less than 2
