Please help :) idk what the answer is
Varvara68 [4.7K]

Answer:

\large\boxed{\dfrac{4}{3}}

Step-by-step explanation:

Look at the picture.

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

From the graph we have two points (0, -4) and (3, 0).

Substitute:

m=\dfrac{0-(-4)}{3-0}=\dfrac{4}{3}

What is the solution to the following system of equations? 3x-4y=35 and 3x+4y=5
natta225 [31]
3x - 4y = 35
3x + 4y = 5
------------------add
6x = 40
x = 40/6 which reduces to 20/3

3x - 4y = 35
3(20/3) - 4y = 35
20 - 4y = 35
-4y = 35 - 20
-4y = 15
y = -15/4

solution is (20/3, -15/4)

iris [78.8K]
No but there's a website where you can calculate what grade you need in order to get a certain grade in the class. Just add the extra credit grade to the grade you have first. 
Also, it's extra credit. Why wouldn't you do it? It's FREE points (sort of).

Just copy+paste this URL into your search bar:
