Find the equation of a line passing through the point (2, 3) and having a slope of 3.
Delvig [45]

Answer:

The answer to your question is the letter B) y = 3x - 3

Step-by-step explanation:

Data

Point = (2, 3)

slope = m = 3

Process

To solve this problem just substitute the values given in the slope-point equation.

Formula

               y - y1 = m(x - x1)

   x1 = 2      y1 = 3

-Substitution

              y - 3 = 3(x - 2)

-Expand

              y - 3 = 3x - 6

-Solve for y

             y = 3x - 6 + 3

-Result

             y = 3x - 3

What is the result when 6x^3+25x^2+20x+46x
goldenfox [79]

Answer:

The answer to your question is 2x² - 29x + 26

Step-by-step explanation:

dividend =  6x³ - 25x² + 20x + 4

divisor    =  3x + 2

                             2x² - 29x + 26

               3x + 2    6x³ - 25x² + 20x + 4

                            -6x³ -   4x²  

                              0   - 29x² + 20x

                                   + 29x² + 58x

                                       0         78x + 4

                                                 -78x - 52

                                                    0   - 48

quotient =   2x² - 29x + 26

remainder = -48

Result =  2x² - 29x + 26 - 48/6x³ - 25x² + 20x + 4

the measure of ∠D is 5 times the measure of ∠E the two angles are supplemanty find the measure of each angle
hammer [34]
Because the angles are supplementary, they add to 180 degrees.

I solved this by dividing \frac{180}{6} which gives me 30 degrees.

multiply 30 by 5 gives you 150.

and 30 + 150 = 180
