Answer:
-21 and 63 are the possible values
Answer:
the answer is 20
Step-by-step explanation:
20/2= 10. 10-6= 4.
Answer:
-1 and -2, or 9 and 10
Step-by-step explanation:
If x is the smaller integer:
x (x + 1) = 14 + 4 (x + x + 1)
x² + x = 14 + 4 (2x + 1)
x² + x = 14 + 8x + 4
x² − 7x − 18 = 0
Factor using AC method:
(x − 9) (x + 2) = 0
x = -2 or 9
x is the smaller integer, so the larger integers are -1 and 10. Check each pair of solutions.
-1 and -2:
(-2) (-1) = 14 + 4 (-2 + -1)
2 = 14 + 4 (-3)
2 = 2
9 and 10:
(9) (10) = 14 + 4 (9 + 10)
90 = 14 + 4 (19)
90 = 90
Both solutions work.
Answer:
Perpendicular lines have opposite reciprocal slopes, so the slope of the line is -.5
Now, y=.5x+b, so you plug in the point -2,6.
6=.5(-2)+b
6=-1+b, so b=7.
The equation is y= .5x+7
