Answer: y = (-1/2)x + (-3)

Step-by-step explanation:

x + 2y + 6 = 0

2y + 6 = -x

2y = -x - 6

y = (-x - 6) / 2

y = -x/2 - 6/2

y =(-1/2)x - 3

y = (-1/2)x + (-3)

Find the gradient of the line segment between the points<br> (-1,2) and (-2,3).
Svetach [21]

Answer:

The gradient of the line segment between the two points is -1

Step-by-step explanation:

The gradient of the line segment between two points is also known as the slope,

We  can find this by using the formula; y₂ - y₁ /  x₂ - x₁

The points given to us are;(-1,2) and (-2,3).

This implies x₁ = -1  ,     y₁=2         x₂ =  -2        y₂= 3

We can now proceed to insert our values into the formula;

Gradient = y₂ - y₁ /  x₂ - x₁

                = 3 - 2  /  -2-(-1)

                 = 1  /  -2 + 1

                  =1/-1

Gradient = -1

Therefore the gradient of the line segment between the two points is -1

Simplify: 3x(x^2 + 4x - 5)
Alina [70]

Answer:

3x^3+ 12x^2-15x

Step-by-step explanation:

First, you would have to distribute the 3x to everything in the parentheses. So you can write it out as (3x*x^2)+(3x*4x)+(3x*5). Solving this will give you the answer. We'll start off with (3x*x^2). Because we are MULTIPLYING, this part will equal to 3x^3. There is ONE x with 3x (think of it as 3x^1) and 2 x's in x^2, having a total of 3 x's, or x^3. Since the 3 is being multiplied as well, we can write it as 3x^3.

Second, we will solve (3x*4x). We are multiplying, so first we multiply 3*4 and then x*x. 3*4 is 12 and x*x is x^2.  There are 2 x's being mutipled by each other, so the x becomes squared. Now we finish and multiply 12*x^2 wich is 12x^2.

Lastly, we solve (3x*5). 3x is being multiplied 5 times which gives us 15x.

I hope this helped :)
