Answer:

simplifies to -2x -17 = 5x -10
x = -1 . . . . the solution

Step-by-step explanation:

-2(x+5)-7=3x+2(x-5) . . . . starting equation

-2x -10 -7 = 3x +2x -10 . . . eliminate parentheses using the distributive property

-2x -17 = 5x -10 . . . . . . . . . collect terms

-7 -2x = 5x . . . . . . . . . . . . . add 10

-7 = 7x . . . . . . . . . . . . . . . . . add 2x

-1 = x . . . . . . . . . . . . . . . . . . . divide by 7

Answer:

x intercept is 8

y intercept is 4

Step-by-step explanation:

x-intercept -> format is (x, 0)

We know that y=0, so we can substitute that in and solve for x to find the x-intercept. x-2y = x - 2(0) = x = 8. Therefore, the x-intercept is 8.

y-intercept -> format is (0, y)

We know that x=0, so we can substitute that in and solve for y to find the y-intercept. x-2y = 0 - 2y = 2y = 8 -> y =4. Therefore, the y-intercept is 4.

I hope this helps! :)

A line is drawn so that it passes through the points (-3,0) and (1.4). What is the slope of the line?

vladimir2022 [97]

Answer: $m=1$

Step-by-step explanation:

For this exercise you can use the following formula for calculate the slope:

$m=\frac{y_2-y_1}{x_2-x_1}$

In this case you know that the given line passes through the points (-3,0) and (1.4). Therefore you can identify that:

$y_2=0\\y_1=4\\\\x_2=-3\\x_1=1$

Then, in order to calculate the slope of this line, you must substitute the coordinates of the points into the formula:

$m=\frac{0-4}{-3-1}$

Finally, evaluating, you get that the slope of this line is the following:

$m=\frac{-4}{-4}\\\\m=1$
