Answer:

(-3.1, -32.5)

Step-by-step explanation:

Set the equations equal to each other: 25x+45=15x+14

Solve for x: 10x = -31

Solve for x: x=-3.1

Plug the x value back into one of the equations to find the value of y:

y = 15 (-3.1) +14

y = -32.5

Answer:

7,68

Step-by-step explanation:

y=2x+54

y=15x+14

you can do elimination so you need to multiply the x's by -15 and 2

y=-30x+54

y=30x+15

the x's are canceled out and you add the remaining

y=54. y=68

y=15

To find x you makes an equation of one of the equations given

68=2x+54

14=2x

7=x

IgorC [24]

Answer:

$13540

Step-by-step explanation:

Divide 100 from $59000 in which you get 1% of that worth.  If he gets 6% of that commission rate then he would get $3540 since 1% is $590 and you multiply by 6 to get that number.  Since he makes $10000 a month as stated, you would then add the amount $3540 for his salary to get $13540.

The probability is 0.69.

We find the z-scores that correspond with each end of the range we're looking for.  To find a z-score, we use the formula:
z=\frac{X-\mu}{\sigma}&#10;\\&#10;\\=\frac{350-500}{75}=\frac{-150}{75}=-2

z=\frac{400-500}{75}=\frac{-100}{75}=-1.33

Using a z-table (http://www.z-table.com) we see that the area under the curve left of the score 350 would be 0.228.  The area under the curve left of the score 400 would be 0.918.  To find just the range between 350 and 400, we subtract the area left of 350 from the area left of 400; this will give us just from 350 to 400:

0.918-0.228 = 0.69.
