2 answers:
Answer:
y=mx+bx
Step-by-step explanation:
You could either use (7,19) or (9,29) to find the equation....
Y=mx+b
You plug in you x and y, then we are trying to solve for b
x=7, y=19
19=m(7)+b
7m+b=19
-7m -7m
b= 19 - 7m
Y=7m+1

Step-by-step explanation:
so 17 squared minus 8 squared is 225. the square root of 225 is 15
4p - 2 when p=8
(4 x 8) - 2
32 - 2
30
answer: 30
hope it helped :)
3/x=5/y multiply both sides by y
3y/x=5 divide both sides by 3
y/x=5/3
Answer:
30
Step-by-step explanation:
Each z-score = 1 standard deviation from the mean, so 18 + (6 x 2) = 30
for the red it is 5out of 15 or 3/5
and for the blue it is 4/15
and if it wants it together it is 9/15 or 3/5
hope this helps
