If there’s a graph, draw a triangle and do rise/run.
If there are two given points use formula: (y2-y1)/(x2-x1) to find slope

Answer:

The slope is the rise over run. The change in y over the change in x. Pick two points on a line and find the change. It is usually represented by m in the slope intercept form.

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

Pick two points on a line and use the formula m to find the slope, which represents the rate of change.

The polynomial equation x3- 4x2 + 2x+ 10 = x2 - 5x-3 has complex roots 3+2i. What is the other root? Use a graphing
Ivahew [28]

Answer:

Step-by-step explanation:

Given Equation:

x^3- 4x^2 + 2x+ 10 = x^2 - 5x-3

which simplifies to

x^3- 5x^2 + 7x+ 13 = 0

Given one of the roots is x = 3x+2i, the conjugate is therefore x = 3-2i.

The product is real, (x-3+2i)(x-3-2i) = x^2-6x+13

The other root can therefore be obtained by long division

(x^3- 5x^2 + 7x+ 13)/(x^2-6x+13) = x+1, or x=-1

Therefore the three roots are:

{x=3-2i, x=3+2i, x=-1 }

What is the value of a?<br><br> 5(a-4)-8a=55? <br> Please help :)
Ad libitum [116K]
If you want to calculate 5*(a-4) - 8*a = 55, you have to do few steps to get to know the value of the a.

5*a - 20 - 8*a = 55
-3*a = 55 + 20
-3*a = 75   /(-3)
a = - 25

The correct result and the value of the a is -25.

PLS PLS HELP!!! I NEED THIS DONE PLS!!!

The domain and the range are 0 ≤ ∅ ≤ 2π and -1 ≤ cos(∅) ≤ 1, respectively.

<h3>The domain and the range</h3>

The domain is the set of input values i.e. the ∅ values.

On the table, we can see that the ∅ value is from 0 to 2π.

This means that the domain is 0 ≤ ∅ ≤ 2π

On the other hand, the range is the set of output values i.e. the cos(∅) values.

On the table, we can see that the cos(∅) value is from -1 to 1.

This means that the range is -1 ≤ cos(∅) ≤ 1

Hence, the domain and the range are 0 ≤ ∅ ≤ 2π and -1 ≤ cos(∅) ≤ 1, respectively.

<h3>The points on a graph</h3>

<h3>The graph of the function</h3>
