12feet<br> 12 feet<br> HELP ME PLS SNJSNAKSKW
Flauer [41]

Answer:

20 feet.

Step-by-step explanation:

Pythagoreans theorem states that a^2 + b^2 = c^2

a = 12, squared = 144

b = 16, squared = 256

144 + 256 = 400

√400 = 20

20 feet is the answer.

Hope this helps.

3) Y-3=4(n=2)<br>*to draw graph​​​​
Kazeer [188]

Answer:

[see below]

Step-by-step explanation:

I am assuming that you mean: y-3=4(x-2).

The equation is in point slope form...

y-y_1=m(x-x_1)

The point used in the equation is (2, 3). 2 replaces 'x1' and 3 replaces 'y1'.

If you convert the equation in to slope intercept form:

y-3=4(x-2)\\\\y-3=4x-8\\\\y-3+3=4x-8+3\\\\\boxed{y=4x-5}

You get -5 as the y-intercept.

So, the line you draw would pass through points (2,3) and (0,-5).

Hope this helps.
