Write the sentence as an equation and solve. Twice the difference between 5 times a number and 6 is 18. please help!​
Dmitry_Shevchenko [17]
Twice the difference between 5 times a number and 6 equals 18:

2(5x-6)=18

We need to solve for x:

5x - 6 = 2(difference) = 18

The difference must equal 9.
In order for the difference to equal 9, x must equal 3.

5(3) - 6 = 2(difference) = 18

Let's solve:

15 - 6 = 2(9) = 18

Therefore, in this equation, x = 3.

Answer:

d. y = x + 6

Step-by-step explanation:

Equation of AD can be written in the slope-intercept form, y = mx + b

First, find the slope (m) and y-intercept (b) of line AD.

✔️Slope (m) = change in y/change in x

Using two points on line AD, (-5, 1) and (0, 6):

Slope (m) = (6 - 1)/(0 - (-5))

Slope (m) = 5/5

m = 1

✔️y-intercept (b) is the point where the line cuts across the y-axis = 6

b = 6

✔️To write the equation, substitute m = 1 and b = 6 into y = mx + b

y = 1(x) + 6

y = x + 6
