Answer: y = -5x - 3.


Explanation:


When you know the slope and the y-intercept you can directly write the slope-intercept equation of the line.


The slope-intercept equation of the line has the form: y = mx + b, where m is the slope and b is the y-intercept.


Here you know m = -5 and b =  -3, hence you just have to substitute those values in the general slope-intercept form, which is:

  • y = -5x - 3.

That equation represents the line, which means tha every point in the line will be an ordered pair of the function. For example:


  x            y = -5x - 3

- 10          -5(-10) - 3 = 50 - 3 = 47

  0            0 - 3 = - 3 (this is the y-intercept)

10            -5(10) - 3 = - 50 - 3 = - 53

lions [1.4K]

In the question it is given that,

The students at Midtown Middle school sold flowers as a fundraiser in September and October. In October, they charged $1.50 for each flower

And the October price was a 20% increase of the September price.

Let the price of the flower in October be $x

So we have

x+  \frac{20}{100}x = 1.50 \\ \frac{120x}{100} = 1.50 \\ x = \frac{1.50*100}{120} = 1.25

So the price of the flower in Septembet is $1.25 .

We know the area of the middle rectangle is 48 (length * width). removing that rectangle leaves us with two semicircles. you can combine those semicircles to be the equivalent of one circle. the area for a circle is r^2 * pi. we know the diameter is 4 because that is where we cut the semicircles. radius is half the diameter, so r is 2. 2^2 is 4, 4* pi is 12.56. add 12.56 (area of semicircles) with 48 (area of rectangle) and we get 60.56
