Answer:

(100,113) is on the graph of y = 1.2x -7

Step-by-step explanation:

y=1.2x−7

Substitute the point in and see if the equation is true

113 = 1.2 (100) -7

113 =120 - 7

113 = 113

This is true, so the point is on the graph

9.1(6)+8.7(7)=_+60.9 How do I solve this?

timurjin [86]

Answer:

The answer is 54.6.

9.1(6)+8.7(7)=54.6+60.9

Step-by-step explanation:

Given:

9.1(6)+8.7(7)=_+60.9

Now, to solve it:

9.1(6)+8.7(7)=_+60.9

Let the _be x.

So, we remove parenthesis first that makes it multiply with the number next to it:

$9.1\times 6+8.7\times 7=x+60.9$

$54.6+60.9=x+60.9$

Now adding on L.H.S:

$115.5=x+60.9$

Subtracting on both sides by 60.9 we get:

$54.6=x$

$x=54.6$

Therefore, the answer is 54.6.

A 20 foot ladder is resting against the side of the house the base of the latter is 4 feet away from the house approximately how

notka56 [123]

The ladder resting against the house forms a triangle similar to the one in the image below

To answer this question you must use Pythagorean theorem

$a^{2} +b^{2}=c^{2}$

a and b are the legs (the sides that form a perpendicular/right angle)

c is the hypotenuse (the side opposite the right angle)

In this case...

a = x

b = 4

c = 20

^^^Plug these numbers into the theorem

$x^{2} +4^{2} =20^{2}$

solve for x

$x^{2}$ + 16 = 400

$x^{2}$ = 384

x = 8√6

x ≈ 19.5959....

Hope this helped!
