Answer:
The simplified expression of (4-5r+8s)(5r-9) is
40r s-25r^2-72s+65r-36
(hope this helped)
This will not factor so you can use the quadratic formula
x = [- (-3) +/- sqrt(9 - 4*5*-4) / 10
= (3 +/- sqrt 89) / 10
= 3 + 9.434 / 10 or 3 - 9.434 / 10
= 1.24 , -0.64 to the nearest hundredth
The answer is $26.00 because
$6.50*(4+1)= $6.50*5, which is $26.00.
hope this helps you.
Let the number of baskets be x
Let the number of points be y
32 +3x = y
19 + 4x = y
Rearrange both equations then solve them as simultaneous equations
32 = y - 3x
19 = y - 4x
y - 3x = 32
- y - 4x = 19
x = 13
Substitute x into one of the equations
y - 3x = 32
y - (3 x 13) = 32
y - 39 = 32
y = 32 + 39
y = 71
Number of baskets (x) = 13
Number of points (y) = 71
