Answer:

Answer:

Step-by-step explanation:

hello :

The equation of a linear function in point-slope form is y – y1 = m(x – x1)

The point is A (x1 , y1)

in this exercice : y + 3 = -4(x - 5)     the slope is m= -4

3(x - 4) + 6 = 5(x - 1) + 1 solve for x and show work

Answers

Answer:

x= -1

Step-by-step explanation:

open brackets and calculate

3x - 12 + 6 = 5x -5 + 1

Calculate

3x - 6 = 5x - 4

transpose

3x - 5x = - 4 + 6

Calculate

- 2x = 2

x= 2/-2

x= -1

Answer:

X = -1

Step-by-step explanation:

3(x - 4) + 6 = 5(x - 1) + 1     -distribute

3x - 12 + 6 = 5x - 5 + 1     -combine like terms

3x - 6 = 5x - 4        -subtract 3x

-6 = 2x - 4        -add 4

-2 = 2x      -divide by 2

-1 = x

what is the simplelest form of the following expression? 6c^2+2.5d-d+2c^2-3d a) 4c^2-1.5d b)6c^2+0.5d c)8c^2-1.5d d)8c^2+1.5d

Answers

6c^2 + 2.5d - d + 2c^2 - 3d combine like terms 6c^2 + 2c^2 = 8c^2 2.5d - 1d - 3d = 2.5d - 4d = - 1.5d now put them together 8c^2 - 1.5d any questions ?

Answer:

The correct option is c.

Step-by-step explanation:

The given expression is

6c^2+2.5d-d+2c^2-3d

Like terms are those terms which have same variable having same degree.

On combining like terms we get

(6c^2+2c^2)+(2.5d-d-3d)

On simplification we get

(8c^2)+(-1.5d)

8c^2-1.5d

The simplest form of given expression is 8c^2-1.5d.

Therefore the correct option is c.
