Answer:
1) C
2)C
3)C
Step-by-step explanation:
in y=mx+b the
m is the slope, b is the y-intercept
y is the output, x is the input
1) The slope is -2 and y-intercept is 3
so y= -2x+3 which is C
2) Slope:6/5 and y-intercept is -4
so y= 6/5x-4 which is C
3) Slope: -1 and y-intercept is 2
You don't put 1x or -1x it's just x.
so y= -x+2 which is A
Hope this helps:)
Answer:
r = 44
Step-by-step explanation:
12 = r - (34 - 2)
Solve for r
___________
To solve, we need to isolate r.
Distribute the negative sign with the numbers within the parenthesis :
12 = r - 34 + 2
Add like terms :
12 = r - 32
Add 32 to both sides :
44 = r
r = 44
Answer: C
Step-by-step explanation:l
Answer:
Yes, this is a function.
Step-by-step explanation:
This is a function because every input goes to exactly one output. Although 1 is listed twice in this example, it still goes to the same output of 15.
<span>Old Surface Area = 202 ft^2
New Surface Area = 1818 ft^2
Notice we have this ratio:
(new area)/(old area) = 1818/202 = 9
and how 3^2 = 9. This is no coincidence.
The old surface area is multiplied by 3^2 = 9 to get the new surface area
.
If you asked "What would the surface area of the prism be if each dimension were quadrupled?"
, then you would multiply the old surface area by 4^2 = 16 to get the new surface area So really thats how you would solve that </span><span />
