Answer:

2

Step-by-step explanation:

The equation of a horizontal line is y = c

where c is the value of the y- coordinates the line passes through

Thus y = 3 ← is the equation of a horizontal line

Variable y varies directly with variable x, and y = 6 when x = 9.

lesantik [10]

X and y are proportional hence when y is multiplied by a number, x is multiplied by the same number.

18=6*3 hence when y=18,x=9*3=27

x=27

write the standard form of the line that passes through the given points include your work in your final answer type your answer

Gemiola [76]

The slope is change in "Y" divided by the change in "x"
1-(-3)/2-(-1)
= 4/3

Standard Form
y-y1=m(x-x1)
y-(-3)=4/3(x-(-1)
y+3=4/3x+4/3
y=4/3x-5/3

Rewrite in standard form
-4/3x+y=-5/3
Can't have fractions so multiply by 3 to get rid of the denominator
-4x+3y=5
Divide by -1 to get rid of the negative sign

4x-3y=-5

You want to put a 5 inch thick layer of topsoil for a new 16 ft by 34 ft garden. The dirt store sells by the cubic yards. How ma

shepuryov [24]

Answer: About 8.5 cubic yards

Step-by-step explanation:

Given : The length of the garden = 16 ft.

The width of the garden = 34 ft.

The depth of the thick layer of topsoil on the garden = 5 inch

= $\dfrac{5}{12}\text{ ft.}$ [Since 1 foot = 12 inches]

The volume of a rectangular prism :-

$V=l*w*h$ , where l is length , w is width and h is height.

The number of cubic feet of topsoil required will be

$V=16\times34\times\dfrac{5}{12}=\dfrac{680}{3}\text{cubic feet}$

Since 1 yard = 3 feet

$1\text{ foot}=\dfrac{1}{3}\text{ yard}$

$V=\dfrac{680}{3}\times\dfrac{1}{3}\times\dfrac{1}{3}\times\dfrac{1}{3}=8.3950617284\approx8.50\text{cubic yards}$
