I’ll explain how to graph them since there are quite a few problems. :)

The easiest way to graph is to first put down the y-axis, which is the end number on the end of the equation. For example, on the first problem the y-intercept is 5, so for this point you would just plot down (0,5).

Next you would just plot down points that follow the slope, which is the first number in the equation, and in the first problem it is 1/2.
The top number determines if you go up and down the bottom number determines where you go right. *only when the slope is negative will you go down for the top part of the slope*
For example, in the first problem you would start plotting from where you put your y-axis and go 1 up and 2 down to plot your next point. You would follow this trend another time or two until you can make your line.

A rectangle has an area of 36 inches squared. Write an equation to show how the length (l) varies inversely the width (w).
Anastaziya [24]
Start with the first sentence, and the definition of the area of a rectangle:
l * w = 36

Rewrite the equation to get
l = 36 / w
or
w = 36 / l
Either one shows the inverse relationship between w and l.

Assuming the last part wants you to write an equation for an x-y graph, the equation would be
y = 36 / x

3. A children's slide is 10 feet long and inclines 64° from the ground. The
Nata [24]

Answer:

  87.0°

Step-by-step explanation:

The law of sines can be used to solve this. We have two sides of a triangle and the angle opposite one of them. We want to find the angle opposite the other known side.

In the attached, the triangle is ΔACS. We have side "a" = 9, and side "c" = 10. Angle A is given as 64°. The law of sines tells us ...

  sin(C)/c = sin(A)/a

  sin(C) = (c/a)sin(A)

  C = arcsin((c/a)sin(A)) = arcsin(10/9·sin(64°)) ≈ 87.03°

The ladder makes an angle of about 87° with the ground.

How √225 and √223 are different by their nature ??
denis23 [38]
Here, we know, √225 = 25 (perfect squared)
whereas √223 is not a perfect squared.

So, √225 would be "Rational" whereas √223 would be "Irrational" by the nature.

Hope this helps!
