Answer:
-7000,-6000,-5000,-4000,-3000,-2000,-1000,0, 1000,2000,3000,4000,5000,6000,7000
5x - 3y = -11 (×2)
2x - 6y = -14 (x5)
10x - 6y = -22
10x - 30y = -70
---------------------- -
24y = 48
y = 2
The formula for percentage is:
is/of = %/100
In the given problem,
is = ?
of = 25
% = 80
We get,
?/25 = 80/100
"is" is unknown so let "is" be "x"
x/25 = 80/100
We have to cross multiply. Meaning, we will multiply the numerator of one fraction by the denominator of the other fraction. Therefore,
100x = (80)(25)
100x = 2000
x = 20
The answer is 20. The basketball player is expected to make 20 free throw shots out of 25 in the entire game.
Slope is -1/5
Y-intercept is 21
Equation is y=-1/5x+21
Yes it’s proportional :)
