Step-by-step explanation:
Answer:
TS = 22
x = 49
Step-by-step explanation:
(5x-2)/39 = (3x+1)/26
Multiply both sides by 78:
10x-4 = 9x+3
x=7
3x+1 = 22
:::::
(x+5)/36 = 30/20
x+5 = 54
x = 49
The common factors for 28 and 42 are 1, 2, 7 and 14.
Answer:
A
Step-by-step explanation:
A. because the line of best fit has to be at best fit between the points so is a good approximation of where all the points are heading when you try to predict something.
Answer:
-8x^2-10x+12
Step-by-step explanation:
first set up the problem:
(-3x^2-7x+5)-(5x^2+3x-7)
Since you are subtracting you need to distribute the (-) sign:
(-3x^2‐7x+5)(-5x^2-3x+7)
Now just combine like terms
-3x^2+(-5x^2= -8x^2
(-7x+(-3x= -10x
5+7= 12
set answer in standard form:
-8x^2-10x+12
