Answer:

Terrell drove 200 miles one way

Step-by-step explanation:

Since his trip concluded at 9 hours, let's say that x = time traveled at 40 mph

and 9 - x = time traveled at 50 mph

D = (rate) x (time)

40x = 50(9 - x) -----Use Distributive property on the right side of the equation

40x = 450 - 50x -----Add 50x on both sides

90x = 450 ------Divide by 90 on both sides

We end up with x = 5 which is the value we need to determine the distance of our first trip, calculated by

D = 40x, or 40(5) = 200 mi

Which expression is equivalent to 6m+(m-2)(m+7)+3

Vika [28.1K]

Answer:

$m^{2}$ + 11m - 11

Step-by-step explanation:

6m+(m-2)(m+7)+3 = 6m + [ m*m - 14 -2m + 7m] + 3

= 6m + mm - 14 + 5m + 3

= mm + 11m - 11

6m+(m-2)(m+7)+3 = $m^{2}$ + 11m - 11

Write the equation of the line that passes through the points (3,5) and (-1,1). Put

dangina [55]

Given:

A line passes through the two points (3,5) and (-1,1).

To find:

The equation of the line in fully reduced point-slope form.

Solution:

If a line passes through two points, then the point slope form of the line is

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

The line passes through the two points (3,5) and (-1,1). So, the point slope form of the line is

$y-5=\dfrac{1-5}{-1-3}(x-3)$

$y-5=\dfrac{-4}{-4}(x-3)$

$y-5=1(x-3)$

Therefore, the point slope form of the line in fully reduced form is $y-5=1(x-3)$ , here 1 is the slope of the line.

Coefficient of 24x+32+4x+3

coldgirl [10]

Firstly, you can combine like terms, or terms that have the same variable and exponents.

24x and 4x both have the variable "x" so it can be combined to make 28x

A coefficient is basically just the number that's used to multiply the variable

In this case, the variable is "x" and the number that will be multiplied to x is 28.

The coefficient is 28.
