He messed up in the beginning with the 4.

It's supposed to be
(3 - -4)
(3 + 4)

and not

(3-4)

That's where he messed up.

I find it interesting how he uses Xa Ya and Xb Yb. In my school we use X1 Y1 and X2 Y2.

What is the answer to this!!!!

prisoha [69]

All you have to do is set up an equal proportion $\frac{height}{length}$ or $\frac{x}{180 inches(15 feet)}$ = $\frac{85}{51}$ cross multiply to get 51x = 180*85 which is simplified to 51x = 15300 divide both sides by 51 to get x = 300 inches. Since the answer choices are in feet, divide 300/12 to get 25 feet

Write an equation in slope intercept form for the line that passes through (-6,-2) and has a slope of 1/3

BabaBlast [244]

Answer:

y=1/3x-2

Step-by-step explanation:

Since the slope intercept form formula is y=mx+b all we need to do is input the values. So m is the slope. Input 1/3. X is next to it because we solve for this. B is the y intercept. Meaning its the point that crosses the line on the graph that is vertical. And you already have -2. Since we know: (x,y) so choose the y. And you have your equation.

Hope this helps!! If so please mark brainliest and rate/heart to help my account if it did!!

2^-3/2^-5 A)2^2 B)1/2^2 C)2^8 D)1/2^8

CaHeK987 [17]

Here is your answer

A) $\huge{2}^{2}$

REASON :

CONCEPT USED: $\frac{{a}^{m}}{{a}^{n}}$

= ${a}^{m-n}$

So,

$\frac{{2}^{-3}}{{2}^{-5}}$

= ${2}^{-3-(-5)}$

= ${2}^{-3+5}$

= ${2}^{2}$
