If you look carefully at the graph, you'll see that the line goes smack through the intersection of x=4 and y=3, and thus "rise" is 3 and "run" is 4.

The slope is then m = rise/run = 4/3.

1.3n-0.03=-9 (solve for n) grade lvl. 7

bazaltina [42]

Hello from MrBillDoesMath!

Answer:

-6.9

Discussion:

1.3n - 0.03 = -9 => multiply both sides by 100

130n - 3 = -900 =>

130n = -900 +3 = -897 => add 3 to both sides

n = -897/130 =>

n = - (69 * 13)/ (10*13) =>

n = - 69/10 = - 6.9

Thank you,

The height of a cylinder is 5 centimeters. The diameter of the base of the cylinder is 16 centimeters. Find the lateral surface

soldier1979 [14.2K]

Answer:

Lateral surface area of the cylinder = $251.2 cm^2$

Step-by-step explanation:

Lateral surface area of he cylinder = $2*\pi*r*h$ i.e area of side surface.

$Height(h) = 5 cm$

$Diameter = 16 cm$

$radius(r)= 16/2= 8 cm$

Lateral surface area of the cylinder = $2*\pi *8*5$

$\pi =\frac{22}{7}=3.14$

L.S.A= $2*3.14*8*5$

L.S.A= $251.2 cm^2$

The lateral surface area of the cylinder with radius 8 cm and height 5 cm is $251.2 cm^2$

When graphing any equation what is a great fall back plan if you can't remember the learned procedure? (on all kinds of equation

miv72 [106K]

Answer:

GOOGLE :)

equation:

y=mx+b

m= slope (how steep the line is(negative is \ positive is /))

b= y intercept (where it is on the vertical line(up and down line))

step by step

1. locate y intercept and plotthe point

2.from that point use slop to find second point and plot
