The equation y=my+b is the slope- intercept form of a linear equation solve y=mc+b for m
SVEN [57.7K]

We need to leave m alone on the right hand side, so let's move everything else to the left hand side.

First of all, we can subtract b from both sides to get

y-b = mc

Now, we can divide both sides by c to get

\dfrac{y-b}{c}=m

And so we solved the expression for m, because we have written an expression in the form m=\ldots, where the right hand side doesn't depend on m.

What is the volume of a hemisphere with a radius of 2.3m round to the nearest tenth of a cubic meter
kodGreya [7K]

Answer: 25.5 m^{3}

Step-by-step explanation:

If the volume of a sphere is

V=\frac{4}{3} \pi r^{3}

Where r=2.3 m is the radius

The volume of a hemisphere is half the volume of the total sphere:

V_{hemisphere}=\frac{V}{2}=\frac{\frac{4}{3} \pi r^{3}}{2}

V_{hemisphere}=\frac{2}{3} \pi r^{3}

Solving this equation:

V_{hemisphere}=\frac{2}{3} \pi (2.3 m)^{3}

Finally:

V_{hemisphere}=25.48m^{3} \approx 25.5 m^{3}

The cost for renting a weed trimmer varies directly with the number of hours used. A weed trimmer rented for 5 hours costs $32.5
wlad13 [49]
Let the cost for renting be y and the number of hours be x
then:
y=kx
where:
k is the constant of proportionality
k=y/x
y=$32.5 when x=5 hours
thus;
k=32.5/5
k=6.5
hence the equation is:
y=6.5x
thus the value of y when x=8 hours will be:
y=6.5(8)=$52
Answer:'

<span>A y = $6.5x, y = $52.00</span>
