Graph -27x+18y=54??????????

Mathematics
1 answer:
Sindrei [870]4 years ago

Answer:

There should be 3 points that you have.  (0, 3), (2, 6), and (-2, 0)

Step-by-step explanation:

Alright so since everything there is divisible by 9 you can divide each number by 9 to get:

-3x + 2y = 6

Now, to graph this you need to put it in y = mx + b form. So, add the 3x to both sides of the equation.

-3x +2y = 6

+3x            +3x

2y = 3x + 6

Now you would divide 2 on both sides because you need y to be alone, to get:

y = 3/2 x + 3

Now Graphing:

Since 3 is positive that is your y-axis.  So put a dot on + 3 on the y-axis.  That's your (0, 3) point.  

Then 3/2 is your slope.  Slope is rise / run.  So you start at your dot from the y-axis go up 3 (because that's your rise from slope) then you go to the right 2 (therefore, your run) then place a dot there.  This is your (2, 6) point)

Usually you want to do the negative side of that also.  To do that you would once again start at the 3 (y-axis point).  Now you would pretty much make your slope negative.  Starting at 3, you would go down 3 (your rise for slope) then go to the left 2 (your run for slope).  This is your (-2, 0) point.  

Do you understand it?

the length of a rectangle is 3 ft more than twice the width, and the area of the rectangle is 77ft. Find the dimensions of the r
gladu [14]
Let x = width
2x + 3 = length

Area of rectangle is length times width

x(2x + 3) = 77
2x² + 3x = 77
2x² + 3x - 77 = 0
2x² + 14x - 11x - 77 = 0
2x(x + 7) - 11(x + 7) = 0

(2x - 11)(x + 7) = 0

x = 11/2, - 7

Distance/measurements can't be negative so x = 11/2

The length:
2(11/2) + 3
11 + 3
14

Your width is 11/2 feet and your length is 14 feet.

Jack crawled 3 ft and Christine crawled 3⁄4 the distance Jack crawled. If you add the distance they each crawled together, what
LUCKY_DIMON [66]
Christine crawled:
3 ft* (3/4)= 2.25 ft.

3 ft+ 2.25 ft= 5.25 ft

We already know that 1 ft= 12 in.

5.25 ft* (12in/ 1 ft)= 63 in.

The total distance the two children crawled together is 63 in~

What is the answer? how do i find it?
Dovator [93]

The answer is C. 8,000 kg/m³.

Density is calculated by dividing the mass by the volume.

D= \frac{3,200 kg}{0.4 m^{3}}

D= 8,000 kg/m³
