Answer:

2/5x-1

Step-by-step explanation:

In order to solve this you just have to multiply the factors that are inside the parenthesis by 1/3:

\frac{1}{3}(\frac{6}{5}x-3)\\\frac{6}{3(5)}x -\frac{3(1)}{3} \\\frac{2}{5}x-1

By reducing the fraction you get that the result would be 2/5x-1 when expanding the multiplication of  1/3(6/5x-3)

A line with a slope of –2 passes through the point (–4, 8). What is the equation of the slope-intercept form?
zloy xaker [14]

Answer:

y= -2x

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.

Given that the slope is -2, m= -2.

subst. m= -2 into the equation:

y= -2x +c

To find the value of c, substitute a coordinate.

When x= -4, y=8,

8= -2(-4) +c

8= 8 +c (expand)

c= 8-8 (-8 on both sides)

c=0 (simplify)

Thus, the equation of the line is y= -2x.

what are the steps to solve 3.5(c-8)+c=12.5? I already went on a different website and found out the answer is nine. I plugged i
LekaFEV [45]
3.5(c-8)+c = 12.5
⇒ 3.5c- 3.5*8+ c= 12.5 (distributive property)
⇒ (3.5c+ c) -28= 12.5
⇒ 4.5c= 12.5+ 28
⇒ 4.5c= 40.5
⇒ c= 40.5/ 4.5
⇒ c= 9

The correct answer is 9~
