First you distribute. 4 to x-1 and 3 times 2x-5 you should get 4x-4-6x+15 because -3 times -5 is positive 15. Combine like terms 6x-4x is 2x and 15-4 is 11

Answer:

11-2x

Step-by-step explanation:

4(x-1)-3(2x-5)

Open the brackets

4x-4-6x+15

Collect like terms

4x-6x-4+15

11-2x

For which rational expressions is –5 an excluded value? Check all that apply.

Anika [276]

Answer:

option C and F

Step-by-step explanation:

Given excluded value is x=-5

Excluded value are the values that makes the denominator 0

Now we check out each option and see , in which option the denominator becomes 0 when x=-5

When denominator has (x+5) then when we plug in x=-5

(x+5) becomes (-5+5) =0

So we look at the options that has factor (x+5) in the denominator

In option C we have x^2 -25

When we plug in -5 for x then it becomes (-5)^2 - 25 =0

So x=-5 makes the denominator 0

-5 is an excluded value for option C

Last option f has x+5 in the denominator

x=-5 make the denominator 0

so , -5 is an excluded value for option F

Which are the x-intercept and y-intercept of the line drawn through the points A and B?

ladessa [460]

First you have to figure out what the equation of the line is. Let's use the slope formula to find the slope, and then one of the points to find the y-intercept. We'll put the line's equation in y=mx+b form.

$slope = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1} } \\ slope = m \\ m = \frac{5 - 1}{-7 - 1} \\ m = \frac{4}{-8} \\ m = - \frac{1}{2}$

Now, we'll use that slope in y=mx+b form with one of the coordinates in order to find what b (which is also the y-intercept) equals
$y = - \frac{1}{2}x + b \\ 1 = 1(- \frac{1}{2}) + b \\ 1 = - \frac{1}{2} + b \\ 1 \frac{1}{2} = b$

therefore your y-intercept is equal to 1.5. In order to find the x-intercept we'll take our new equation $y = - \frac{1}{2} + 1 \frac{1}{2}$ and make y = 0, because the line intersects with the x-axis when y is equal to zero.

$y = - \frac{1}{2}x + 1 \frac{1}{2} \\ 0 = - \frac{1}{2}x + 1 \frac{1}{2} \\ -1 \frac{1}{2} = - \frac{1}{2}x \\ x = 3$

therefore, your x-intercept is 3 and your y-intercept is 1.5
