Black shirts / total shirts
3/(5 + 3 + 8) = 3/16 <=== the probability of picking a black shirt

The area in square feet of a rectangular field is x^2-100x+2400. The width, in feet is x-40. What is the length, in feet?

sattari [20]

Answer:

x-60

Step-by-step explanation:

You have to factor out the quadratic.

You know that one of the factors is x-40.

To factor:

Find a number that when added to -40, gives you -100, and also when multiplied, gives you 2400.

That such number is -60.

Add an x before it, and you get (x-60)

Find the equation of line parallel to y=-2x+1 and passing through the point (2,4)

SOVA2 [1]

Answer:

$y=-2x+8$

Step-by-step explanation:

Hi there!

<u>What we need to know:</u>

Linear equations are typically organized in slope-intercept form: $y=mx+b$ where m is the slope and b is the y-intercept (the value of y when x is 0)
Parallel lines always have the same slopes

<u>1) Determine the slope (m)</u>

$y=-2x+1$

The given line has a slope of -2. Because parallel lines always have equal slopes, we know that the line parallel to this would also have a slope of -2. Plug this into $y=mx+b$ :

$y=-2x+b$

<u>2) Determine the y-intercept (b)</u>

$y=-2x+b$

Plug in the given point (2,4) to solve for b

$4=-2(2)+b\\4=-4+b$

Add 4 to both sides to isolate b

$4+4=-4+b+4\\8=b$

Therefore, the y-intercept of the line is 8. Plug this back into $y=-2x+b$ :

$y=-2x+8$

I hope this helps!
