Answer:

300 = x

Step-by-step explanation:

150= 100(.60) + x(.30)

150 = 60 + x(.30)

150 - 60 = 60 - 60 + x(.30)

90 = x(.30)

90/.30=x(.30)/.30

300 = x

Could someone explain this to me
Bond [772]

Answer:

Step-by-step explanation:

The question is asking you to graph the equations.

The equations are in slope intercept form so y=mx+b

M is the slope and b is the y-intercept

First draw the y & x axis and label/number them

The y-intercept for the first equation is -1 so draw a dot on the -1 on the y-axis

The slope is 2/5 and you use rise/run to continue the slope.

you rise 2 on the y-axis and go right 5 times on the x-axis (for a negative number you go left/down)

For the second equation, you have to turn it into slope intercept form.

You should get y=2/3x+3

You graph this equation the same as you did the first one.

What is the value of 10C3?
Zigmanuir [339]
The answer is B. 120

nCr = n! / ((r! * (n - r)!)

n = 10
r = 3

10C3 = 10! / ((3! * (10 - 3)!)
         = 10! / ((3! * 7!)
         = (10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1) / (3 * 2 * 1 * 7 * 6 * 5 * 4 * 3 * 2 * 1)
         = 3628800 / 30240
         = 120
