Answer:
2.5
Step-by-step explanation:
5x+3x=20
8x=20
x=20/8=2.5
The answer is 7x-3 if you add like terms which are 4x, 2x, and x then take 2, 3, -2 and subtract from each other
Answer:
-2x² - 8x - 15
Step-by-step explanation:
-(2x² + 4x + 11) + (-4)
-2x² - 8x - 11 - 4
-2x² - 8x - 15
Answer:
The endpoint coordinates are (3,12)
Step-by-step explanation:
You multiply 4 by 2 which gives you 8 and write the equation
then you subtract 5 from 8 to get 3 for the x coordinate.
You multiply 3 by 2 which gives 6 and writhe the equation
then you substitute the -6 for +6 and add +6 and 6 to get 12 for the y coordinate.
To check use the midpoint formula with coordinates D and your endpoint coordinates
and you get the answer for the midpoint which is (4,3)
