Answer:

Y=3x+2, Y= -3x-2

Step-by-step explanation:

If you need a consistent (parallel) line you must have very similar equations, with only positives and negatives being changed. If it's Y=3x+2, only the 2 is changed from negative to positive changing the lines position. If it's Y= -3x-2 then the X value is moved to a different coordinate and the -2 keeps the change.

Hope this helps and please critique what I've done if im wrong.

What is the volume of a cylinder with a height of 2 feet and a radius of 6 feet? Use 3.14 for pi. Enter your answer in the box.

erastovalidia [21]

Answer:

$V=226.08\ ft^3$

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

$V=\pi r^{2} h$

where

r is the radius of the base of the cylinder

h is the height of the cylinder

we have

$r=6\ ft\\h=2\ ft\\\pi=3.14$

substitute the given values in the formula

$V=(3.14)(6)^{2}(2)\\ V=226.08\ ft^3$

the figure is made up of a semicircle and a triangle. Find the area of the figure. Use pi equals 3.14

valentinak56 [21]

Answer:

The area of the figure is 63.25 square feet

Step-by-step explanation:

we know that

The area of the figure is equal to the area of semicircle plus the area of triangle

step 1

Find the area of semicircle

The area of semicircle is

$A_1=\frac{1}{2}\pi r^{2}$

we have

$r=10/2=5\ ft$ ----> the radius is half the diameter

$\pi =3.14$

substitute

$A_1=\frac{1}{2}(3.14)5^{2}$

$A_1=39.25\ ft^2$

step 2

Find the area of the triangle

The area of triangle is equal to

$A_2=\frac{1}{2}bh$

we have

$b=8\ ft\\h=6\ ft$

substitute

$A_2=\frac{1}{2}(8)(6)$

$A_2=24\ ft^2$

step 3

The area of the figure is equal to

$A=A_1+A_2$

substitute

$A=39.25+24=63.25\ ft^2$

How do u solve -8+10

Pachacha [2.7K]

If you were on a number line you go over 10 numbers to the left. Therefore, you will pass all of these numbers...
-7,-6,-5,-4,-3,-2,-1,0,1,2. Your answer will be 2.

A chess club with 55 members is electing a new president. Lucy received 33 votes. What percentage of the club members voted for

bonufazy [111]

You would put it up into proportions so 33 over 55 equals x over 100. Then you would cross multiply so 55x=3300. Then you would divide 3300 by 55 and get 60%.
