Parallel lines have the same a slope.

The slope-intercept form:

$y=mx+b$

A line passes through the points (-2, -4) and (3, 5).

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

Substitute:

$m=\dfrac{5-(-4)}{3-(-2)}=\dfrac{5+4}{3+2}=\dfrac{9}{5}$

Substitute to the slope-intercept form:

Answer: $y=\dfrac{9}{5}x+b,\ b\in\mathbb{R}$

Answer:

r = √(3V/(πh))
r ≈ 1.78 cm

Step-by-step explanation:

Multiply by the inverse of the coefficient of r², then take the square root.

$V=\dfrac{1}{3}\pi r^2h\\\\V=\dfrac{\pi h}{3}r^2\\\\r^2=\dfrac{3V}{\pi h}\\\\\boxed{r=\sqrt{\dfrac{3V}{\pi h}}}$

For V=50, h=15, this is ...

${r=\sqrt{\dfrac{3(50)}{\pi(15)}}=\sqrt{\dfrac{10}{\pi}}\approx\boxed{1.78\quad\text{cm}}$

Outta Luck Towing Company charges $50 to hook a vehicle to the truck and $2.75 for each mile the vehicle is towed. Write an equa

Nana76 [90]

Outta Luck Towing Company charges $50 to hook a vehicle to the truck and $2.75 for each mile the vehicle is towed.

Let the number of miles towed is m, and the total charges is c

2.75 for each mile the vehicle is towed

for 1 miles , the charge is 2.75

For m miles , the charge is 2.75m

$50 to hook a vehicle to the truck. so basic charge is 50

Total charge = charge of m miles + basic charge

C = 2.75 m + 50
