Answer:
3(5-y)
Step-by-step explanation:
He's driving 42mph. 42m/60h=0.7mpm. 12 minutes x 0.7 mile per minute= 8.4 miles. 21-8.4=12.6 miles left . 12.6 x 0.7= 8.86 minutes left or about nine

We can deduce that the graph is a negative parabola from
-0.002x^2. Therefore, the graph is increasing < 1250 and decreasing > 1250.
P(x) is increasing from

and decreasing from
![(1250,\infty]](https://tex.z-dn.net/?f=%281250%2C%5Cinfty%5D)
.
Answer:
<h2>x= 37/16</h2><h3>
y=199/8</h3>
Step-by-step explanation:
1....y=11+6x
-77-2x+3y=-7
replace y by ..1..
so -77-2x+3(11+6x)=-7
-77-2x+33+18x=-7
-44+16x=-7
16x=37
y=11+6x
replace x by 37/16
y=11+6*37/16
y=199/8
