3. Rewrite -2x + 3y = 6 in slope intercept form.

zaharov [31]

The equation in slope-intercept form is:

$y=\frac{2}{3}x+2$

Further explanation:

The standard slope-intercept form is:

$y=mx+b$

Given equation is:

$-2x+3y=6$

In order to bring the equation in slope-intercept form we have to isolate y on left hand side of equation

So,

Adding 2x on both sides

$-2x+3y+2x=6+2x\\3y=2x+6$

Dividing both sides by 3

$\frac{3y}{3}=\frac{2x+6}{3}\\y=\frac{2x+6}{3}$

Simplifying

$y=\frac{2x+6}{3}\\y = \frac{2x}{3}+\frac{6}{3}\\y=\frac{2}{3}x+2$

The equation in slope-intercept form is:

$y=\frac{2}{3}x+2$

Susan is 5.5 ft tall and casts a shadow that it is 4 ft long on the ground. She is walking through a park and finds the shadow o

Vika [28.1K]

Answer:

22 ft

Step-by-step explanation:

Height of Susan/Length of shadow = Height of sculpture/Length of Shadow of sculpture

5.5 ft/4 ft = x/16ft

Cross Multiply

4 × x = 5.5 × 16

x = 5.5 × 16/4

x = 22 ft

The height of the sculpture is 22 ft

Adding or subtracting fractions with different denominators

Bas_tet [7]

Step-by-step explanation: You can't continue on with the problem until the denominators are the same. So you need to find the LCD (Least Common Denominator). For example...

$\frac{1}{2} +\frac{1}{3}$ The LCD is six

$\frac{1*3}{2*3}=\frac{3}{6} =\frac{1}{3}$

$\frac{1}{2}+ \frac{1}{3}= \frac{3}{6} +\frac{2}{6}$

$\frac{3+2}{6}= \frac{5}{6}$

Hope this helps, have a BLESSED and wonderful day! :-)

Suzanne wants to put a fence around her square garden. If the garden covers an area of 49ft^2, how many feet of fencing does she

lina2011 [118]

Answer:

The area for a square is given by:

$A = x^2$

And we can find the dimension for one side like this:

$x = \sqrt{A}$

Replacing we got:

$x = \sqrt{49 ft^2}= 7ft$

Then since we are interested in the how many feet of fencing does she need, we can find the perimeter given by:

$P = 4x$ and replacing we got:

$P = 4*7 ft = 28 ft$

Step-by-step explanation:

For this case we know that Suzanne want to put a fance around a square garden with an area of 49 ft^2

The area for a square is given by:

$A = x^2$

And we can find the dimension for one side like this:

$x = \sqrt{A}$

Replacing we got:

$x = \sqrt{49 ft^2}= 7ft$

Then since we are interested in the how many feet of fencing does she need, we can find the perimeter given by:

$P = 4x$ and replacing we got:

$P = 4*7 ft = 28 ft$
