The equation of the line in slope - intercept form is y=\frac{-7}{4}x-5


Explain what the slope-intercept form is?

Simply put, the slope-intercept form is the way to write a line's equation so that the y-intercept (where the line crosses the vertical y-axis) and slope (steepness) are instantly visible. This expression is sometimes referred to as y = mx + b form


Given:
x = -4 , y = 2 and b = -5

y = mx + b

2 = m (-4) + (-5)

m = \frac{-7}{4}
By putting the value of m we get equation of line
y=\frac{-7}{4}x-5

A cylindrical well is 15 meters deep and has a diameter of 1.6 meters. Approximately how many cubic meters of soil were dug out
Lisa [10]
We can dig out the soil from the well equal to volume of well.

Height(h) of well is = 15 meters.

Diameter = 1.6 meters.

So radius(r) = \frac{1.6}{2} = 0.8 meter.

As well in cylindrical shapes.

So volume of well = \pi r^2h
                               = \pi * (0.8)^2 * 15
                                = 9.6 * \pi
 In general \pi = 3.14

So volume of well is = 9.6 * 3.14
                                   = 30.144 cubic meter.

So we can dig out 30.144 cubic meter soil from well.

Brian needs $315 to buy a new cell phone. He has already saved $115 and plans to save an additional
Juliette [100K]

Answer:

34 weeks

Step-by-step explanation:

Hello!

We can set up an equation to solve for the number of weeks.

Let w = the number of weeks he is saving up.

The equation is 315 = 115 + 10w - 140

  • 315 is the target amount
  • 115 is the current amount
  • 10w is the rate of growth
  • 140 is the current debt

<h3>Solve for w</h3>
  • 315 = 115 + 10w - 140
  • 315 = -25 + 10w
  • 340 = 10w
  • 340/10 = w
  • 34 = w

He needs to save up for 34 weeks.
