2<br> Graph y = 2/3x - 4
AysviL [449]

ANSWER:

(IMAGE ATTACHED)

EXPLANATION:

This equation is called a slope intercept form. The formula is y=mx+b.

"b" or -4 in this case is the y-intercept. It's where the line meets the y line (vertical line). The "m" or 2/3 is the slope. All slopes are written in y/x.

So, starting from (0, -4), you will go up 2 and go right 3. You will end up at (3, -2). Now, just draw a line through (0, -4) and (3, -2).

Your graph should show up like this:

Second option. 1.5% of 2,700 is 40.5. Multiply that by 5 and you get 202.5 add that to 2,700 and you get 2,902.5. Round that and you get 2,903. Hence, the second option is correct.

You need to cover the playground of a child development center with mulch. The playground is 125 feet long and 60 feet wide. You
alexira [117]
Volume of this child development center=long x width x deep.
we expressed all magnitudes (long, width and deep) in yards.
Data:
long=125 ft=125 ft * (1/3 yd/ft)=125/3 yd
width=60 ft=60 ft * (1/3 yd/ft)=20 yd
deep=6 in * (1 yd / 36 in)=1/6 yd

We calculate the volume:
volume=(125/3 yd)*(20 yd)*(1/6 yd)=138.8888....yd³≈139 yd³

Answer: 139 yd³

Which point can be found using the vertical line x = –9 and the horizontal line y = 8?
Fudgin [204]
ANSWER

The point is
(-9,8).

EXPLANATION
When two nonparallel lines are drawn on the same plane, they will intersect at a unique point. This point represents the solution to the two systems of equations represented by the lines.

The vertical line
x = - 9

and the horizontal line
y = 8

will intersect at
(-9,8).

This is the unique solution to the two equations.

See graph.
