Answer:
Slope (m) is the number being multiplied by x (make sure you include the sign in front of it).
y- intercept (b) is the number other than the x
Step-by-step explanation:
Answer:
5,2
Step-by-step explanation:
Clockwise rotations for 90 is
The preimage of (x,y), or for this problem, (-2,5) into (y,-x).
So, a clockwise rotation is from x,y into y,-x
So we do -2,5 into 5,2
We flipped the x and y, and the 2 became positive because two negatives equal a positive
Answer:
it is a right angle triangle therefore
h²=b²+p²
8²=4²+p²
64-16=p²
48=p²
under root 48 =p
6.928
so 6.93 is the answer
To calculate the average you add up all the scores and divide by the number of scores (5)
add all the current test scores and allow X to be the unknown score:
92+80+88+93+X: or 353 + X
set up equation:
(353+X)
______ = 90
5
Multiply both side of the equation by 5 to clear the fraction resulting in:
353+X=450
Subtract 353 from both sides of the equation:
x = 97
So the test score needed to get a 90 average is 97.
