5 0

Answer:

x = - 4

Step-by-step explanation:

Given

5x - 11 = 7x - 3 ( subtract 7x from both sides )

- 2x - 11 = - 3 (  add 11 to both sides )

- 2x = 8 ( divide both sides by - 2 )

x = - 4

A student walks 1/4 Mile from her home to the store on her way to a friend's house if the store is 1/3 of the way to a friend's
exis [7]

the store is 1/3 the way to her friend's house, not 1/3 mile.

this explains solution:

1/3x = 1/4

x = 1/4 * 1/3

x = 3/4

Notes:

X: is the total distance.

1/3 is the one portion of total distance.

1/4 mile is the distance store.

(5x^2+20x) ÷(x+4) divide, it's really important, I thank you for the people who help me in this :)
Sergio [31]

Answer:

5x

Step-by-step explanation:

Given expression: \frac{5x^2+20x}{x+4}

Take the common number 5 outside in the numerator.

\frac{5x^2+20x}{x+4}=\frac{5(x^2+4x)}{x+4}

Now, take x common in both the terms in numerator.

\frac{5(x^2+4x)}{x+4}=\frac{5x(x+4)}{x+4}

Cancel out the common factor in the both numerator and denominator.

\frac{5x(x+4)}{x+4}=5x

Hence, the answer is 5x.

How does y=mx+c work
kolbaska11 [484]
Ok so, y = mx + c is the equation of a line
When a graph is written in this form, m is the slope/gradient and c is the y - intercept.
This form is needed when a question asks for the equation.
Lets say they give 2 sets of coordinates, we can use the point slope formula to find the slope (m)

point slope formula:
(y₂ - y₁) = m(x₂ - x₁)

Then we substitute any of the two set of coordinates to find c, the y - intercept. 

So the line has a gradient of m and y - intercept of c
