Solution:

<u>Note that:</u>

  • 64 × x/100 = 28

<u>Simplifying the LHS:</u>

  • 64 × x/100 = 28
  • => 64x/100 = 28

<u>Using cross multiplication:</u>

  • 64x/100 = 28
  • => 64x = 2800

<u>Divide 64 both sides.</u>

  • => x = 2800/64 = 43.75%

28 is 43.75% of 64

28 is 43.75% of 64
you can calculate this by making a fraction of 28/64 and timing this by 100!

Find the slope and y intercept of y= -3x - 2
sergejj [24]

Answer:

slope = -3

y-intercept = -2

Step-by-step explanation:

y = mx + <em>b</em>

m = slope; <em>b</em> = y-intercept

y= -3x <em>- 2</em>

m = -3 = slope

<em>b = -2 = y-intercept</em>

Answer:

1. -3/6 is negative, because it descends by 3 and goes over by 6.

2. My first answer literally gives the keyword negative, therefore it's a negative line because it has a <em>negative slope</em>.

1. -8/0 is undefined, because there is a rise but there is no run, which also means that it's a:

2. vertical line

1. -5/-10 simplifies to 5/10 or 1/2, which is positive because it rises by 5(or 1) and runs over by 10(or 2).

2. Thus, this means that it's a positive line since it has a <em>positive slope</em>.

1. 0/-2 is zero, because when you actually solve the equation it'll equal 0.

2. This means that it'll have a horizontal line since there is no rise but there is a run only.

3. Write the equation of a line that passes through the point (24, 25) and is
IceJOKER [234]

Answer:

y=-1/3x + 33

Step-by-step explanation:

You can start by writing this in point slope form and converting to slope intercept later. Since the slope of the perpendicular line is y=3x-30, this line must have a slope of -1/3. It's point slope form is therefore:

y-25=-1/3(x-24)

Now, you can convert to slope intercept by isolating y:

y=-1/3(x-24)+25

y=-1/3x+8+25

y=-1/3x+33

Hope this helps!
