p = 32
Solution:
Given p represents the amount of air pressure in a tire.
t represents the time it takes for the tire to go flat and t = –8.
To find the value of p, if .
⇒
Substitute t = –8 in the above equation.
⇒
Do cross multiply, we get
⇒ p = (–8) × (– 4)
⇒ p = 32
Hence, the value of p is 32 if the quotient is –4.

Answer
Find out the percentage of students from the north side of the city in the program .
To prove
Formula
As given
A magnet school program was set up to bring in students from all over the city. With the first 112 students .
the magnet program had 50% from the south side of town, 12.5% from the north side l, and 37.5% from the east side.
12 .5 % is written in the decimal form.
= 0.125
North side student be = 0.125 × 112
= 14
As given
If 6 more student from the north side and 2 students from the west side side enrolled in the program .
than north side student becomes = 14 + 6
= 20
Total number of student becomes = 112 + 6 + 2
= 120
put in the above formula
= 16.66% (approx)
Therefore 16.66% (approx) students from the north side of the city in the program .
Answer:
y = -3x - 3
Step-by-step explanation:
Slope m = (y2-y1)/(x2-x1)
Using both (-1,0) and (1,-6)
then m = (-6 - 0)/(1 - -1) = (-6)/(1 + 2) = -3
then y = mx + b => y = -3x + b
Using (-1,0)
then 0 = -3(-1) + b => 0 = 3 + b => b = -3
so y = -3x - 3
