1/21x = 1/7
 x = 1/7 * 21
x = 21/7
x = 3 <===

7.96/2 = 3.98 <==

Write the equation of the line fully simplified slope-intercept form.
zmey [24]

Answer:5y=x-35

Step-by-step explanation:

The given line passes through the points (0,-7),(10,-5).

Let the slope of the line be m.

If a line passes through (x_{1},y_{1}) and (x_{2},y_{2}),then

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

So,m=\frac{-7-(-5)}{0-10}=\frac{1}{5}

Y-intercept of a line is defined as the y-coordinate of the point where the line touches y axis.

Let the y intercept be b

From the graph,b=-7

The equation of the line with slope m and y-intercept b is y=mx+b

So,y=\frac{1}{5}x-7

5y=x-35

You install 580 feet of fencing along the perimeter of a rectangular yard. The width of the yard is 144 feet. What is the length
muminat
<h3>Answer:   146 feet</h3>

==========================================================

Explanation:

  • P = 580 is the perimeter of the rectangle
  • W = 144 is the width
  • L = unknown length

The units for each are in feet.

The formula tying together all three variables is

P = 2(L+W)

which is the same as saying

P = 2L+2W

We can think of it having two copies of L and two copies of W, four sides total, added together to get the full perimeter.

I'll go with the first version. Plug in the given values and solve for L

P = 2(L+W)

2(L+W) = P

2(L+144) = 580

L+144 = 580/2

L+144 = 290

L = 290-144

L = 146 feet is the length

---------------

We can confirm this by saying

P = 2(L+W) = 2(146+144) = 2*290 = 580

Or we could say

P = 2L+2W = 2*146+2*144 = 292+288 = 580

or,

P = L+W+L+W = 146+144+146+144 = 580
