The graph the system of linear equations on a coordinate plane is added as an attachment and the solution is (2, 2)

A system of linear equations is a collection of at least two linear equations.

In this case, the system of equations is given as

y=-1/2x+3 and y=2x-2

Rewrite the equations in the system of equations as follows:

So, we have the following representation

y = -1/2x + 3

y = 2x - 2

Next, we plot the graph of the system of equations

See attachment for the graph of the system of equations

In this case, the point of intersection of the equations represent the solution to the system

From the graph, the lines intersect at (2, 2)

This means that the solution to the system of equations is (2, 2)

Recall that

y = -1/2x + 3

y = 2x - 2

Solution = (2, 2)

So, we have

2 = -1/2 x 2 + 3 = 2 --- true

2 = 2 x 2 - 2 = 2 --- true

The probability of bike can travel more than 50 miles without refueling is 0.1151, according to the question.

What do you mean by probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

According to data in the given question,

We have the given information:

Mean = 44

deviation = 5

Let X be the random variable that represents the population's average number of motorcycle kilometers; in this instance, we know the distribution for X is provided by:

X ~ N(44.5)

Where μ=44 and σ=5,

We are interested on this probability,

P(X>50)

We can also apply the z score formula from:

z=x-μ/σ

Using this formula, we obtained:

P(X>50) = P(X-μ/σ > 50-μ/σ) = P(Z > 50-44/5) = P(z > 1.2)

Using the normal standard distribution and the complement rule, we can determine this probability, giving us:

P (z > 1.2) = 1 - P(z > 1.2) = 1 - 0.8849 = 0.1151

Therefore, the probability is 0.1151.

The graph of the new function compared to the first one will be shifted down.

Vertical translation describes the movement of a function graph upward or below. The function's form is preserved in this case. The graph moving or shifting along the y-axis is another name for it. Each point on the graph moves k units vertically during vertical translation, and the graph is said to have translated k units.

The two functions are

f(x) = x + 2

g(x) = x - 1

You can see that all you need to do to transform f into g is just take 3 off of it.

f(x) - 3 = (x+2) - 3

= x + 2 - 3

= x - 1

= g(x)

Every transformation, such as f(x) f(x) + k, now produces a vertical translation, which is translated upward if k > 0 and downward if k 0. The correct response is C since the function is translated three units down in our situation where k = -3.

The number of pounds of strawberries sold and the number of pounds of blueberries sold are 50 and 23 respectively.

As in the question Keilantra runs a farm stand that sells strawberries and blueberries. Each pound of strawberries sells for $2.25 and each pound of blueberries sells for $4. Keilantra made $204.50 from selling a total of 73 pounds of strawberries and blueberries.

Let x be a number of strawberries and y is that of blueberries.

2.25x + 4y = 204.5-----------------------(1)

And

x + y = 73--------------------------------------(2)

On solving equation (1) and (2), we get,

x = 50 and y = 23

If $10,000 is invested at x percent simple annual interest for n years, the total amount of interest would be F = 10,000n(x/100)

Simple interest is a quick and straightforward technique to compute interest on money. In the simple interest method, interest always applies to the initial principle amount, with the same rate of interest for each time cycle. When we put our money in a bank, we receive x percent simple annual interest on it. Banks charge many kinds of interest, one of which is simple interest. Now, before delving further into the idea of simple interest, let's first define what a loan is.

A loan is an amount borrowed by a person from a bank or other financial institution to meet their requirements. Home loans, auto loans, student loans, and consumer lending were just few examples of loans.

How to solve?

F = P(1+rt), where Future value is F, Present value is P, Rate is R, Time is t

F = 10,000(1+xn)

F = 10,000(xn)

F = 10,000(n * x/100)

F = 10,000n(x/100)

hi

Phil's final debt after 20 years will be around $320,679.

To purchase a home, Phil borrowed $150,000 from a bank at a 3.5% annual interest rate.

The annual compounding of interest causes the amount of interest for each year to rise in proportion to the debt. Phil will be required to pay the initial sum plus interest after the first year, which comes to

$150,000 + 3.5% of $150,000 = $155,250.

Since interest is charged on the new amount owed for the second year, Phil will owe

$155,250 + 3.5% of $155,250, which

= $160,551.75.

For the next 20 years, this procedure is repeated, with the amount owed rising yearly by the sum of the year before plus interest. Phil's debt after 20 years will be around $320,679.

The speed of current and average speed of paddling is 3 and 7 respectively.

Let p represents paddling speed of kayack guide  and c represents speed of current.

If paddling downstream, the total speed is p + c because you’re paddling with the current. Similarly, if paddling upstream, the total speed is p - c because you would be paddling against the current.

Since paddling downstream took  2 hours so distance covered 2*(p + c)

which is equal to 20 miles.

2*(p + c) =20.

p + c = 10. -----i

Paddling upstream took 4 hours so distance covered 4*(p-c).

which is equal to 16 miles.

4*(p-c) = 16.

p - c = 4.  -------ii

adding both equation c will be cancelled. 2*p=14 p =7.
