Answer:

x = -2

Step-by-step explanation:

-9x + 1 = -x + 17

To solve this equation

Note if there is more than one variable like x, y, or z

Also note the power of the variables, for example, x^2 or y^3

In this equation, there is only one variable which is x and it's also in the power of 1 ie x

Step 1 : rearrange according to like terms

-9x + x = 17 - 1

( don't forget that the sign always change on crossing an equals to, either + to - or - to +

-9x + x (also means 9 - 1 but only carries a negative sign)

= - 8x = 16

Dividing both sides by -8 to get the value of x

-8x / 8 = 16 /- 8

x = 16/ -8

x = -2

What is the rate of change in decimal form for the points (1,5) (0,-3)

seraphim [82]

Answer:

The rate of change between (1, 5) and (0, -3) would be 8.0.

Step-by-step explanation:

"What is the rate of change between these two points" is the same as asking "what is the slope between these two points".

We are given the two points (1, 5) and (0, -3) and we are asked to find the rate of change (slope) between these two points. To do this, we could use the slope formula to find the rate of change between the two points. The slope formula is:

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

where (x₂, y₂) and (x₁, y₁) are the two points that we are trying to find the slope between.

Lets make (x₂, y₂) = (1, 5) and (x₁, y₁) = (0, -3). (It does not matter which is (x₂, y₂) and which is (x₁, y₁)). Now plug (x₂, y₂) = (1, 5) and (x₁, y₁) = (0, -3) into the equation:

$\frac{5-(-3)}{1-0} =\frac{8}{1}=8$
