Answer:
9) slope of AC = slope of FH
Equation of the line is y = - x + 5
10) Area = 320
Step-by-step explanation:
For 9, the only thing similar IS the slope of the hypotenuse because the triangles are along the same line. Unless they're asking for the equation of the line, then that's just using the point slope equation which is:
y = - x + 5
For 10, just multiply 4 and 5 by 4 to get 16 and 20. Then multiply 16 and 20 to get 320.
Your percentage of change would have to be about 21.05, but the full answer is 21.05263. Since we are going to need to round to the nearest percent, you would have 22% decrease. The difference in the change is -20.
Answer:
the MEAN for class a is 72.6
the MEAN for class b is 84.0
if you take these means and compare them, you can see that on average, class B performed better.
the MEDIAN for class a is 72
the MEDIAN for class b is 85
Step-by-step explanation:
Answer:
-9x + 3
Step-by-step explanation:
You would distribute first.
− ( x + 3 ) − 2 ( 4x − 3 ) → -x − 3 − 8x + 6
(If you see a negative sign in front of a parenthesis without a number, its usually a negative 1)
From there, you would combine like terms.
-x − 3 − 8x + 6 → -9x + 3
