Solving the first equation for y:

We can see both equations are exactly the same, so there is only one equation and one line.

Let's give x some values and graph the line.

x = 0:

x = 2

With the points (0, 2) and (2, 1) we graph the line as follows.

Since the number of equations is greater than the number of unknowns, the system has infinitely many solutions. For example, (0, 2) and (2, 1) are solutions for the system.

Step-by-step explanation:

It is assumed you need to convert the given function into vertex form.

Converting in below steps:

We got:

The slope intercept form of the line for (-1,0) and (4,-5) is y = -x -1.

We know that,

Slope intercept form of a line is given by:-

y = mx + c

Where,

m is the slope of the line,

c is the y -intercept of the line and,

(x,y) is the ordered pair of each point on the line

We know that,

m = (-5-(-1))/(4 - 0) = (-5 +1)/4 = -4/4 = -1

Putting (-1,0) in the line, we get

0 = (-1)*(-1) + c

0 = 1 + c

c = -1

Hence, the equation of the line is given by:-

y = -1x -1 = -x - 1

The value of X is ([tex](A-CB)^{-1}[/tex] CD.

Given,

AX[tex](D+BX)^{-1}[/tex] = C

Multiply both sides on the right by (D+BX):

AX[tex](D+BX)^{-1}[/tex] × (D+BX) = C × (D+BX)

AX ([tex](D+BX)^{-1}[/tex] (D+BX)) = C(D+BX)

AX × I = CD + CBX

AX = CD + CBX

Subtract CBX on both sides and factor:

AX – CBX = (CD + CBX) – CBX

AX – CBX = CD + (CBX – CBX)

AX – CBX = CD + 0

(A – CB)X = CD.

Multiply both sides on the left by [tex](A-CB)^{-1}[/tex] :

([tex](A-CB)^{-1}[/tex] × (A – CB)X = ([tex](A-CB)^{-1}[/tex]  × CD

([tex](A-CB)^{-1}[/tex] × (A – CB)) X = ([tex](A-CB)^{-1}[/tex]  CD

IX = ([tex](A-CB)^{-1}[/tex] CD

X = ([tex](A-CB)^{-1}[/tex] CD.

Earthquakes are caused by human activity, like tunnel construction, filling reservoirs that leads to a sudden release of stress along faults in the earth's crust.

An earthquake is caused as a result of a sudden slip on a fault in the earths outermost layer.

The genesis of this discussion is that the tectonic plates are usually moving slowly. However, these tectonic plates may  get stuck at their edges as a result of undergoing friction. Now, after the stress on the edge overcomes the friction, there would be an earthquake that would release energy in form of waves travelling through the earth's crust that leads to the shaking of the earths surface that humans experience in an earthquake.

Given that the triangles are corresponding triangles, then ∠B ≅ ∠E, therefore:

m∠B = m∠E

Replacing with data:

3v + 4 = 8v - 6

3v is adding on the left, then it will subtract on the right

6 is subtracting on the right, then it will add on the left

4 + 6 = 8v - 3v

10 = 5v

5 is multiplying on the right, then it will divide on the left

10/5 = v

2 = v

Then, the measure of B is:

m∠B = 3v + 4 = 3(2) + 4 = 10°

The measure of angle B is 10°

The angle the pole makes with the tent is 39.7°.

What is an angle?

An angle is a figure in Euclidean geometry created by two rays, called the sides of the angle, that share a common termination, called the vertex of the angle.

Angles formed by two rays are located in the plane containing the rays.

Trigonometric ratio: the trigonometric ratio is used to demonstrate the relationship between the sides and angles of a right-angled triangle.

Let θ represent the angle the pole makes with the tent.

Using trigonometric ratios:

cos(θ) = 20/26

θ = 39.7°

Therefore, the angle the pole makes with the tent is 39.7°.

The function which represents the phone rate is a straight line, which can be gotten by the following formula:

Where m is the slope, and b the point where the y-axis is crossed by the line.

Let's get the slope first:

And b = 25 because (0, 25) is where the line has crossed the cost axis.

Therefore:

Since the segment MN is the diameter of the circle, the arc MACN has an angle with a measure of 180°, Then by adding the measures of the angles of the arcs MA, AC and CN we should get 180°, like this:

mMA + mAC + mCN = 180

By replacing 55° for mMA and 65° for mCN, we can solve for mAC to get:

55 + mAC + 65 = 180

120 + mAC = 180

120 - 120 + mAC = 180 - 120

mAC = 60

The measure of the arc ACN is calculated by adding the measures of the angles AC and CN, then we get:

mACN = mAC + mCN

mAC = 60 + 65

mAC = 125

Then, the angle of ACN has a measure of 125°

The given experiment is a die that is tossed three times.

X is the sum of the three numbers obtained.

You need to determine if the random X variable has a binomial distribution.

First, we need to understand what makes a random variable has a binomial distribution. There are 4 conditions to be met:

1. There are a fixed number of trials N

2. Each trial has only two possible outcomes: success or failure

3. The probability of success is equal in each trial

4. The trials are independent.

In this case, condition 1 is met, but condition 2 is not met, since in each trial we can obtain 6 different numbers, then there are not only two possible outcomes, but 6, then the sum of the three numbers has more than two possible outcomes. So, the random X variable doesn't have a binomial distribution.

Note that the graph shows us that the minimum and maximum value of the ages are 40 and 75, respectively.

We can count the number of bars on the histogram. We see that the are 7 bars in total.

Each bar consider the same age span, so that means that each bar represent an age span of the same amount of years.

To calculate this range, we first find the difference between the maximum and the minimum, that is

Now, we divide this number by the total number of bars. That is

So, each bar represents a range of 5 years .

Since the minimu is 40, this means that the first bar should represent ages from 40-44. Note that despite the difference between 44 and 40 is only 4, since we are including age 40 in the first bar, we have numbers 40,41,42,43,44 (5 numbers ) associated to the first bar.

This means that for the next one, which is the range T we are looking for, the correspondent age range should be 45-49

Considering the definition of percent of error, the Stephanie’s percent of error in this case is 5.042%.

Percent of error is a measure of how inaccurate a measurement is, standardized based on the size of the measurement.

In other words, the percent of error allows knowing the differences between the estimated value and the real value. The error may be due to the measurement method (tool or human error) or due to approximations used in the calculation (for example, rounding errors).

To calculate the percent of error you must:

Therefore, the expression for calculating the percent of error is

percent of error= [|real value - estimated value|÷ real value]×100

In this case, you know:

Replacing in the definition of percent of error:

percent of error= [|8.33 pounds - 8.75 pounds|÷ 8.33 pounds]×100

Solving;

percent of error= [|-0.42 pounds|÷ 8.33 pounds]×100

percent of error= [0.42 pounds÷ 8.33 pounds]×100

percent of error= 0.05042×100

percent of error= 5.042%

Finally, the percent of error in this case is 5.042%.
