So it seems to me that you just have to figure our how many minutes it would take for Curtis to ride 6+3=9, so 9 miles. If it takes him one hour to ride 12 miles, how many minutes would it take for him to ride 9? so, 60/12 is equal to x/9, and solve. If you cross multiply and solve, you will get x=45, therefore it takes Curtis 45 minutes to ride 9 miles.

Mt. Mickey is 14,831 feet tall, whereas Mr. Minnie is 18,940 feet tall. How much taller is Mt. Minnie than Mt. Mickey?

kari74 [83]

Answer: 4109 feet.

Step-by-step explanation:

You must subtract the height of Mt. Mickey from Mt. Minnie.

18940 - 14831 = 4109

Please explain on how to get the solution for each variable please

By algebraic handling we find that the unique solution of the system of linear equations is: (x, y, z) = (- 2, 4, 3). (Correct choice: A)

<h3>What is the nature of a system of linear equations?</h3>

If the system of equations has no solutions, then the determinant of the dependent coefficients of the system of linear equations must be zero. Let see:

$D = \left|\begin{array}{ccc}1&1&1\\4&-1&-8\\-1&-1&7\end{array}\right|$

This determinant can be determined by Sarrus' rule:

D = (1) · (- 1) · (7) + 4 · (- 1) · 1 + (- 1) · 1 · (- 8) - (- 1) · (- 1) · 1 + 4 · 1 · 7 - 1 · (- 1) · (- 8)

D = - 7 - 4 + 8 - 1 + 28 - 8

D = 16

The system of linear equations have at least one solution. This system has only one solution any of the three equations is not a function of the other two. By algebraic handling we find that the unique solution of the system is: (x, y, z) = (- 2, 4, 3).

Complete the equation for the linear function whose graph contains the points (-1,-2) and (3.10)

tatuchka [14]

That's point-slope form:

y - y1 = m(x - x1)

Where y1 is the y-value of a point on the line, x1 is the x-value, and 'm' is the slope.

So let's find out what goes in the first blank.

As we can see, they replaced 'x1' with -1, and one of our points have an x-value of -1, that point is (-1, -2), this means y2 must be -2:

y + 2 = m(x + 1)

Now let's find the slope between the two points.

m = y2-y1/x2-x1

m = (10+2)/(3+1)

m = 12/4

m = 3

So the slope is 3, plug that in:

y + 2 = 3(x + 1)
