The answer is y + 2 = -3(x - 1)

This is point slope form so you start with
y-b = m(x-a)
then you would find a point (5, - 1)
then fill in
y-5 = 3(x-1)
then if you want solve it for slope intercept form
y = 3x + 2
graph that and check your work

Two cars travel at the same speed to different destinations. Car A reaches its destination in 17 minutes. Car B reaches its dest

Goryan [66]

Answer:

speed of car A =Speed of car B=0.8 miles/minutes.

Step-by-step explanation:

We are given that speed of car A is equal to speed of car B.

Also let car A travels x miles.

and car B travels y miles.

Car A reaches its destination in 17 minutes.

this means that speed of car A is given by: $\dfrac{x}{17}$ miles/minutes ( since speed is defined as the ratio of distance and time).

Car B reaches its destination in 32 minutes.

This means that the speed of car B is given by: $\dfrac{y}{32}$ miles/minutes

as speed of both cars are equal this means:

$\dfrac{x}{17}=\dfrac{y}{32}$ ------(1)

Also we are given Car B travels 12 miles farther than Car A.

this means $y-x=12$

$y=12+x$ ------(2)

on using equation (1) and (2) we have:

$\dfrac{x}{17}=\dfrac{12+x}{32}\\ \\32x=17(12+x)\\\\32x=17\times12+17x\\\\32x-17x=17\times12\\\\15x=122\times17\\\\x=13.6$

Hence the speed of car A is 0.8 miles/minutes ( since x/17 is the speed of car A)

Speed of car B=0.8 miles/minutes.

What are the factors of 5(x-7)=5x-35

astra-53 [7]

Answer:

0=0

Step-by-step explanation:

Simplifying

-5(x + -7) = 35 + -5x

Reorder the terms:

-5(-7 + x) = 35 + -5x

(-7 * -5 + x * -5) = 35 + -5x

(35 + -5x) = 35 + -5x

Add '-35' to each side of the equation.

35 + -35 + -5x = 35 + -35 + -5x

Combine like terms: 35 + -35 = 0

0 + -5x = 35 + -35 + -5x

-5x = 35 + -35 + -5x

Combine like terms: 35 + -35 = 0

-5x = 0 + -5x

-5x = -5x

Add '5x' to each side of the equation.

-5x + 5x = -5x + 5x

Combine like terms: -5x + 5x = 0

0 = -5x + 5x

Combine like terms: -5x + 5x = 0

0 = 0

Solving

0 = 0

Couldn't find a variable to solve for.

This equation is an identity, all real numbers are solutions.
