Answer:

4/7

Step-by-step explanation:

Let's start by moving like terms to one side. Remember that when you change the side of a term, the sign flips.

-5x-2x=-3-1

-7x=-4

Divide both sides by -7

x=4/7

I think the answer is........

-5x+3=2x-1

-5x-2x=-1-3

-7x= -4

-7x/-7=-4/-7

x=4/7

Answer:

Step-by-step explanation:

Given

- 3 ÷ - $\frac{2}{5}$

Leave the first number, change division to multiplication and turn the fraction upside down, that is

= - 3 × - $\frac{5}{2}$

= $\frac{3(5)}{2}$

= $\frac{15}{2}$

= 7 $\frac{1}{2}$ → D

Please help me if you can ‼️

Answer:

$y=14.5x+5$

Step-by-step explanation:

Let

x ----> the number of tickets

y ----> the price of tickets

we have the ordered pairs

(4,63) and (6,92)

step 1

<em>Find the slope of the linear equation</em>

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{92-63}{6-4}$

$m=\frac{29}{2}=\$14.5\ per\ ticket$

step 2

Find the y-intercept or initial value of the linear equation

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope b is the y-intercept

we have

$m=14.5$

$point\ (4,63)$

substitute

$63=14.5(4)+b$

solve for b

$b=63-14.5(4)$

$b=\$5$

In this context the y-intercept is a one charge fee for the ticket service

The equation is equal to

$y=14.5x+5$
