Answer:
3 hours times 6.80= 20.40
2 hours times 6.20= 12.40
20.40 + 12.40 = 32.80
32.80 ÷ the 5 hours= $6.56 per hour average
Answer:
b
Step-by-step explanation:
Answer:
Step-by-step explanation:
The general formula for slope-intercept form is y = mx + b
We can see that m (slope) equals 1/3 here. We can also see that the y-intercept (b) is -2. Another way to find the y intercept is to make x equal to 0. You get 0 - 2 which equals -2
Note:
If youre ever asked for the x-intercept, make y equal to zero and solve for x.
Answer:
y = -x - 4
Step-by-step explanation:
Plug in the point and slope into the equation y = mx + b, and solve for b:
y = mx + b
-6 = -1(2) + b
-6 = -2 + b
-4 = b
Then, plug in b and the slope into y = mx + b
y = -1x - 4
y = -x - 4 is the equation of the line
Answer:
16 cm^2/min
Step-by-step explanation:
dV/dt=24
V=a^3, differentiate with respect to t
dV/dt=3a^2*da/dt, a^2*da/dt=8
S=6a^2, 216=6a^2. a=6. da/dt=(8/36)
dS/dt=12*a*da/dt=12*(8/6)=16 cm^2/min
