Answer:
The slope is zero. Since both coordinates have the y-value of -1, they are on the same line on the graph and form a horizontal line with a slope of zero. (a straight horizontal line)
Step-by-step explanation:
use the formula
(y2-y1)/(x2-x1)
to calculate the slope using 2 points
so where (x1,y1) (x2,y2) can be subsituted
so putting it in the formula ...
(-1-(-1))/(7-10)=
0/-3=0
The percentage of Chang from 7.50 to 9.00 is 20
Might be 134 because since angle 2 and 8 are lined up like that it is same side exterior angles which means they are supplementary from each other so they will equal 180. So I did 180-46 to get 134, I’m not sure if I’m correct
Answer:
D
Step-by-step explanation:
You have to be careful that you treat 21 as special. It is the only positive number. As you do the problem, keep an eye on 21.
f(-2) = 3x^2 - 2x + 5 Put -2 wherever you see an x
f(-2) = 3(-2)^2 - 2(-2) + 5 Calculate the first term.
f(-2) = 3(4) - 2(-2) + 5 Remove the brackets of the second term
f(-2) = 12 + 4 + 5 Combine
f(-2) = 21
