To solve this, we must first put both lines in Slope Intercept Form (y=mx+b where m is the slope and b is the y-intercept).

y=3x-5 is already in SIF, so we only need to work on the other one.

 x+3y=6
-x       -x
 3y=-x+6
 /3      /3
 y=-1/3x+2

Now we have both equations in slope intercept form, so we can start graphing from the y-intercepts and just follow the slopes.

When we do this, we will see that the lines meet at an exactly 90° angle. When a pair of lines does this, it means they are perpendicular.

Below I have attached an image that has both lines graphed so that you may visualize it. The green dots show the slopes, while the highlighted areas show the y-intercepts. Note that the lines intersect at a 90° angle, making them perpendicular.

Answer: The y is going to be 7

Explanation: Because 5y/35 divide 5 both sides cancel the both 5's and y stays by itself and 35/5 equals 7. 7*5= 35

Jones has a 100-acre farm. he sells it to a developer who is going to build houses. the developer will use 10% of the land for s
Sholpan [36]
The first thing we must do is find the amount of land that will be used for the 120 lots.
 We must remember that 10% of the land will not be used for the lots.
 We have then:
 100 - (0.10) * (100) = 100 - 10 = 90 acres.

 Then, we must consider the following conversion of units:
 1 acre = 43560 ft ^ 2

 Applying the conversion we have:
 (90) * (43560) = 3920400 ft ^ 2

 Then, the amount of square feet for each lot is given by:
 3920400/120 = 32670 ft ^ 2

 Answer:
 
There will be 32670 square feet in each lot.

dangina [55]

Answer:

The wingspan of his model is <u>2.75 feet</u>.

Step-by-step explanation:

Given:

Raul is making a scale model of an airplane that had a wingspan of 44 feet.

If Raul's scale model is 1/16 the size of the actual airplane.

Now, to find the wingspan of his model.

Length of the airplane wingspan = 44 feet.

<em>As given, Raul's scale model is 1/16 the size of the actual airplane.</em>

Now, to get the wingspan of his model:

\frac{1}{16} \ of\ 44

=\frac{1}{16}  \times 44\\\\=\frac{44}{16} \\\\=2.75\ feet.

Therefore, the wingspan of his model is 2.75 feet.
