Answer:
y = 7
Step-by-step explanation:
Firstly multiply each and every term by 9
17/9 - y/3 = -4/9
; 17 - 3y = -4...then move the variabkes without (y) to one side,
; 21 = 3y....then divide both sides by 3
; 7 = y
;Hence..., y = 7
Answer:
btw it olny 8 points but it is c
Step-by-step explanation:
First you have to put all of your common numbers together. 4a and 9a go together. You then subtract those because 9 is negative (-9). Then you get -5a. Now move on to your other numbers. You have 26 and 17. 17 is negative as well (-17), so you subtract it from 26. That gives you 9.
Your new equation is -5a + 9 = 26
Now you subtract 9 from both sides. Your positive (+9) will cancel out with your negative (-9). Then subtract it from 26. 9 minus 26 is 17.
Now your equation is -5a = 17
Since it's negative, you're going to add it (5) to both sides.
Your 5's cancel out, and 17 + 5 is 22.
a = 22
22 is the answer
The equation that models the difference in the projected enrollments for
public schools and private schools as a function of the number of years
since 1985 is B - R = (-18.53t^2 + 975.8t + 48140) - (80.8t + 8049) = -18.53t^2 + 975.8t + 48140 - 80.8t - 8049 = -18.53t^2 + 895t + 40091
They both equal 78 degrees because they are the same angle which means that they have the same degrees for f and e.
