Answer:
1.
-2 = x/4 + 1
Subtract 1 from both sides:
-2 - 1 = x/4 + 1 - 1
-3 = x/4
Multiply both sides by 4:
-3 * 4 = x/4 * 4
-12 = x
2.
3x+5
3.
X= 12 or 18
This could be read two different ways.
0=2/3x-12
12=2/3x
12÷2/3=x
12*3/2=x
18=x
—-OR—-
0=2/3(x-12)
0=2/3x-8
8=2/3x
8÷2/3=x
8*3/2=x
12=x
Answer:
12 * 3x
Step-by-step explanation:
x is equal to the minutes
A.
from the question,
the total speed for the pedestrian is
40km and the total time is 10hr
substitute them in the formula, we get
speed = 4km/hr
B. 10hrs - 6hrs = 4hours
C. BC is deacceleration = -dv/dt
CD is constant acceleration = dt = 0
2450 miles / 35 inches = 70 miles / inch

Answer:
y=mx+b is the equation for a line, x and y being coordinates, m as your slope and b as your y intercept. Slope is rise over run.
