You can solve this using the Quadratic Formula, x =.

a = 1, b = -12, c = 59

x =    Multiply 4 and 1

x =    Multiply 2 and 1

x =    Multiply -4 and 59

x =    Square 12

x =    Subtract

x =    You can't find the square root of negatives, so factor the -92 out.

x =    You can find the square of 4, so take that out.

x =    Split the expression into two parts

x =  (+ or -)    The 2 in the numerator and the 2 in the denominator cancel each other out

x =  (+ or -)    Divide 12 by 2

x = 6 (+ or -)    Now, split the solution into the plus and minus parts.

A ship traveling east at 45 mph is 15 mi from a harbor when another ship leaves the harbor traveling east at 60 mph. How long do
Harman [31]

Answer:

  1 hour

Step-by-step explanation:

I find these easiest to work by considering the initial difference in distance and the speed at with that gap is closing.

__

The gap is 15 miles, the distance the first ship is from harbor when the second ship starts.

The rate of closure is the difference in the speeds of the two ships:

  60 mph -45 mph = 15 mph

Then the closure time is ...

  time = distance/speed

  time = (15 mi)/(15 mi/h) = 1 h

It will take the second ship 1 hour to catch up to the first ship.

Estimate the solution to the system of equations. 7x−y=7<br><br> x+2y=6<br> ​
ElenaW [278]

Answer:

I am not sure how your teacher wanted you to estimate the answer but I solved it for you. Hopefully this helps.

Step-by-step explanation:

7x-y=7

x+2y=6

14x-2y=14

x+2y=6

add both equations

15x=20

x=20/15

x=4/3

x+2y=6

4/3+2y=6

2y=6-4/3

2y=18/3 -4/3

2y=14/3

divide both sides by 2

y= 14/3 divided by 2

y=14/3(1/2)

y=14/6

2y=
