Answer: D

Step-by-step explanation:

The first matrix contains the coefficients of the x- and y- values for both equations (top row is the top equation and the bottom row is the bottom equation. The second matrix contains what each equation is equal to.

[tex]\begin{array}{c}2x-y\\x-6y\end{array}\qquad \rightarrow \qquad \left[\begin{array}{cc}2&-1\\1&-6\end{array}\right] \\\\\\\begin{array}{c}-6\\13\end{array}\qquad \rightarrow \qquad \left[\begin{array}{c}-6\\13\end{array}\right][/tex]

The product will result in the solution for the x- and y-values of the system.

Answer:

The answer is A, D=65h

Step-by-step explanation:

This is because D is representing how far you drove, so you can only drive 65 mph. And that will be 65*h=D. Hope this helps!

The solution is Option A.

The distance traveled is calculated by Distance D = 65h , where h is the number of hours

What is Speed?

Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude

Speed = Distance / Time

Given data ,

Let the distance traveled be represented as D

Now , the value of D will be

Let the speed be represented as S = 65 miles per hour

Let the time required to travel a distance of D be represented as = h

where h is the number of hours

So , the distance D is calculated from the formula

Speed = Distance traveled / Time required

Substituting the values in the equation , we get

65 = D / h

Multiply by h on both sides of the equation , we get

D = 65h

Therefore , the value of D is 65h

Hence , the equation will be D = 65h where h is the number of hours and D is the total distance

Answer:

-5x + 0y = -11

The y terms are eliminated

Step-by-step explanation:

- 4x – 2y = -2

X - 2y = 9

We want to subtract the second equation from the first

Distribute a minus sign to all the terms in the second equation

- 4x – 2y = -2  

X - 2y = 9

= (-5x + 0y = -11)

Answer:

Pretty easy (if you know geometry)!

Step-by-step explanation:

First, we know that A and B have angle bisectors. This means the angles that are divided by that angle bisector are equal (or their measures).

Thus, m<DBA= 1/2 Beta; m<DAB=1/2 Alpha.

Time to find m<ADB. Using the sum of all angles in a triangle = 180* theorem, we can come up with this equation:

[tex]180= m<ADB+\frac{1}{2} \alpha +\frac{1}{2} \beta[/tex]

So, solving:

[tex]180-\frac{1}{2} \alpha -\frac{1}{2} \beta =m<ADB[/tex]

Answer:

201, 500ft²

Step-by-step explanation:

The formula for calculating area in this case is;

A = w × l

This means we're going to take the width of the runway (65ft) and multiply it by the length of the runway (3100ft).

(To make it easier on paper, you can swap the two numbers around, so the higher number is on top, and the smaller number is on the bottom - 3100 × 65. It won't change the answer, but it will make it quicker and easier to get to the result, and lessens the chances making a mistake.)

So the equation you need to do is;

3,100 × 65 = 201, 500.

Add on the units, and there's your answer;

201, 600ft²

Answer:

a. 60 boys

b. 228 total students

Step-by-step explanation:

a. If there are 45 girls and the ratio of girls to boys is 3:4, then there are 60 boys. The common multiple is 15.

3 * 15 = 45

4 * 15 = 60

45:60 = 3:4

——————————

b. First we need to find out how many boys there are.

95 / 5 = 19

19 * 7 = 133

So, there are 133 boys and the given number of girls is 95. To find out how many total students there are, we need to add 133 and 95.

133 + 95 = 228

You travel 15 units of distance along the x-axis

Step-by-step explanation:

You want the distance from (0, 0) to (15, 5) in the x-axis. It is 15. If the question were the distance between the two points, you may use the distance formula or pythagorean theorem.

Answer: 55 degrees

By definition of how the term "central angle" is defined, it is simply equal to the arc measure it cuts off. The central angle JOI subtends or cuts off the minor arc JI which is 55 degrees, so the central angle is also this measure as well.

Put another way, minor arc JI is 55 degrees of a full 360 degree rotation, and so is the angle JOI.

Answer:

142

Step-by-step explanation:

∠2=38 ( corresponding angles)

definition: the angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal.

sum of straight angle=180

∠5+∠2=180

∠5+38=180

∠5=180-38=142 degrees
