Well, it went down from 95 to 85.5, so it dropped by $9.5.
if we take 95 to be the 100%, what is 9.5 off of it in percentage?
Slope-intercept form y = mx + b
where m------> slope
b-------> y-intercept
m= (y1-y2)/(x1-x2)
P1(-3,5) (x1,y1)
P2(2,10) (x2,y2)
m= (5-10)/(-3-2)
m= (-5)/(-5)
m=1
Until now, the equation is y=mx+b
y=1.x+b
y=x+b
But, whe can plug the point P2(2,10) in y =x+b
10 =2 + b
10 - 2 = b
b= 8
Then, the equation is y=mx+b
y= x+8 <-------------------Solution
Verification P1(-3,5) y = x+8 5=-3+8 Ok
P2(2,10) y = x +8 10 = 2+8 Ok
Answer:
x = −2
Step-by-step explanation:
the steps are super long but this is the answer
Answer:
√40 ≈ 6.32
√75 ≈ 8.66
√90 ≈ 9.49
√245 ≈ 15.65
√450 ≈ 21.21
√640 ≈ 25.30
√675 ≈ 25.98
Step-by-step explanation:
You can use your calc or estimate your answer by simplifying (like √640 is 8√10, and estimate the square root of 10). However, getting decimals will require you to use a calc.
