You just add all of it. You can use a calculator.
$19.36 + $21.75 + $32.26 =
$41.11 + $32.26 =
$73.37
The answer is B. $73.37
A number squared would be x squared (x^2)
The product of x squared and ten is 10x^2
Then subtract nine
10x^2 - 9
Answer:
Options A and C
Step-by-step explanation:
<u>To have a unit rate of change of 4.5 means to have the slope at 4.5</u>
A. y = 62 + 4.5x GOOD
B. c = 4.5 + 3h - 1 WRONG
C. c = 12 + 4.5h - 4.5 GOOD
D. y = 3.5x + 1 WRONG
E. y = 4.5 + 20x WRONG
Answer: Options A and C
2x+y=1 can be rewritten as y=-2x+1, with the slope as -2 and the y-intercept at 1. The equation you can use for the table would be (x*-2)+1, or you can just use this:
-2=5
0=1
3=-5
(-2, 5)
(0, 1)
(3, -5)
Answer:
y=3
Step-by-step explanation:
Subtract 30 from both sides
-5y+30=15
-5y=-15
Divide by -5 on both sides
y=3
Hope this helps! :)
