9x^3 - 5x^3 = 4x^3

2x^2 doesn’t substitute with anything

-5x - (-7x) = -5x + 7x = 2x

4 - 4 = 0

Reminders

4x^3 + 2x^2 +2x

If you have have to simplify

2(2x^3 +x^2 +x)

A cab company charges $4 per cab ride, plus an additional $3 per mile driven. How long is a cab ride that costs $22?​
Doss [256]

Answer:

6 miles

Step-by-step explanation:

Flat fee is $4

Per mile is $3

Equation :

4 + 3m = 22

subtract 4 from both sides

3m = 18

divide each side by 3

m = 6

The ride is 6 miles.

If my answer is incorrect, pls correct me!

What is an equation of the line that passes through the point (-4,-6) and is perpendicular to the line 4x+5y=25
elixir [45]

Answer:

y =  \frac{5}{4} x - 1

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx+c, where m is its gradient and c is its y-intercept.

First rewrite the equation of the given line in the form of y=mx +c.

4x+5y=25

5y= -4x +25

y =  -  \frac{4}{5} x + 5

The gradient of the given line is -  \frac{4}{5}

The product of the gradient of perpendicular lines is -1.

( -  \frac{4}{5} )(gradient \: of \: line) =  - 1 \\ gradient \: of \: line =  - 1  \div ( -  \frac{4}{5} ) \\ gradient \: of \: line =  \frac{5}{4}

Thus, m= \frac{5}{4}

y =  \frac{5}{4} x + c

Substitute a coordinate to find c.

When x= -4, y= -6,

- 6 =  \frac{5}{4} ( - 4) + c \\  - 6 =  - 5 + c \\ c = 5 - 6 \\ c =  - 1

Hence, the equation of the line is

y =  \frac{5}{4} x - 1
