Answer:

x = -3

Step-by-step explanation:

-4x + 2(5x - 6) = -3x - 39

-<u>4x</u> + <u>10x</u> - 12 = -3x - 39

-4x + 10x = 6x

6x - 12 = -3x - 39

<u>+3x</u><u>      _ </u><u>+3x        </u>

9x - 12 = -39

<u>     </u><u>+ 12</u><u>   </u><u>+12</u>

<u></u>

\frac{9x}{9} = \frac{-27}{9}

x = -3

-30 = -30

What is the equation of the line in slope-intercept form?
kolbaska11 [484]

Answer:

The equation of the line in the slope-intercept form will be:

  • y = -7x

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where  

  • m is the slope
  • b is the y-intercept

From the attached graph, taking two points

  • (0, 0)
  • (-10, 70)

Finding the slope between (0, 0) and (-10, 70)

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(0,\:0\right),\:\left(x_2,\:y_2\right)=\left(-10,\:70\right)

m=\frac{70-0}{-10-0}

m=-7

Determining the y-intercept:

We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.

From the graph, it is clear that:

at x = 0, y = 0

Thus, the y-intercept b = 0

Now, substituting m = -7 and b = 0 in the slope-intercept form

y = mx+b

y = -7x + 0

y = -7x

Therefore, the the equation of the line in slope-intercept form will be:

  • y = -7x

Phil’s age is 7 years more than times Peter’s age. Also, 4 times Phil’s age is 2 years less than twice Peter’s age. If x is Pete
Rom4ik [11]

Answer:

2x-4(x+7)=2

Step-by-step explanation:

Peter's age:x.... twice age:2x

Phil's age:x+7...4times age:4(x+7)

Difference if ages is 2

Hence; 2x-4(x+7)=2
