Answer:
8x^2 - 26x + 33
Step-by-step explanation:
Add the expressions.
2x^2 - 13x + 12 + 6x^2 - 13x + 21 =
= 2x^2 + 6x^2 - 13x - 13x + 12 + 21
= 8x^2 - 26x + 33
Answer:
(-1, 3)
Step-by-step explanation:
y=5x+8
y= -4x-1
5x+8= -4x-1
5x+4x= -1-8
9x= -9
x= -1
y=5(-1)+8
y= -5+8
y= 3
(-1, 3)
To find the decimals you would have to picture that each of the little lines on the number line are points, for example.
In between 8 and 9, there are 9 lines. The first line would be 8.10, then 8.20, 8.30, and so on...
