You can spend 86 on each family member. 386-42=344
344/4=86
Answer:
-2
Step-by-step explanation:
We have two points we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( -11-1)/(-3 - -9)
= (-11-1)/( -3+9)
= (-12)/6
= -2
Answer:
up
Step-by-step explanation:
A graphing calculator, spreadsheet, or web site can help you with this one, or you can simply plot some points on a graph.
___
Only the highest-degree terms matter for answering this question. Leaving the others out, the form is ...
y = x^2
This tells you that y gets more positive for larger and larger values of x, regardless of their sign. Thus the graph of it is U-shaped, opening upward.
Answer:
Factor out a -1 from one of the terms so they are the same
Step-by-step explanation:
15x^2 – 3x – 20x + 4
(15x2 – 3x) + (–20x + 4)
3x(5x – 1) + 4(–5x + 1)
Talia should notice that the terms in the parentheses are opposites of each other and factor out a -1 out of the second term
3x(5x-1) +4 (-1) (5x-1)
Now the terms have a common factor
(5x-1) (3x+(-1)4)
(5x-1) (3x-4)
Answer:
r = 10
Step-by-step explanation:
You want to find r such that ...
-20 = 60/-6 -r
r = 60/-6 +20 . . . . . add 20+r
r = -10 +20 = 10
_____
If you mean h(x) = 60/(x -r), then the answer is different.
-20 = 60/(-6-r)
-6-r = 60/-20 . . . . . multiply by (-6-r)/(-20)
-r = -3 +6 = 3 . . . . . add 6, simplify
r = -3 . . . . . . . . . . . . multiply by -1
