Answer:   700x+1700

This represents the total amount spent over the x weeks that have gone by.

===========================================

Explanation:

x = number of weeks

700x = amount spent over those x weeks ($700 per week)

700x+1700 = total amount spent when adding on the $1700 tv.

------

An example:

Let's say x = 10 weeks have elapsed. He spends $700 a week, so 700x = 700*10 = 7000 dollars have been spent so far if we ignore the tv. Then add on the $1700 tv cost to get 7000+1700 = 8700 dollars total spent.

Then note how 700x+1700 = 700*10+1700 = 8700 matches what we got earlier.

I recommend trying out other values of x to get a better idea of what's going on.

The t test statistic for the bank's claim that wait times are not longer than five minutes is 4.29.

T - test statistic

T test statistic refer an inferential statistic used to determine if there is a significant difference between the means of two groups and how they are related.

Given,

Wait times for customers once they enter the bank. wait time is defined as the time between when a customer enters the bank until they reach a teller. a random sample of customers are recorded and their wait times in minutes are as follows: (4.21, 5.55, 3.02, 5.13, 4.77, 2.34, 3.54, 3.20, 4.50, 6.10, 0.38, 5.12, 6.46, 6.19, 3.79).

Here we need to determine the t test statistic for the bank's claim that wait times are not longer than five minutes.

In order to find the t test statistic, we have to calculated the average for the given waiting time,

Here the given wait times are:

(4.21, 5.55, 3.02, 5.13, 4.77, 2.34, 3.54, 3.20, 4.50, 6.10, 0.38, 5.12, 6.46, 6.19, 3.79).

In this list there are 15 members timings are presented.

Therefore, the average is calculated as,

=> (4.21 + 5.55 + 3.02 + 5.13 + 4.77 + 2.34 + 3.54 + 3.20 + 4.50 + 6.10 + 0.38 + 5.12 +  6.46 + 6.1 + 3.79) /15

=> 64.3/15

=> 4.29.

Therefore, the t test statistic for the bank's claim that wait times are not longer than five minutes is 4.29.

Step-by-step explanation: :)

The option that must be true of triangle RST include:

m∠R > 90°

m∠S + m∠T < 90°

m∠R > m∠T

m∠R > m∠S

From the information illustrated in the triangle, R > S + T. It should be noted that based on the information, one angle is more than the sum of the other two angles.

Sum of angles in a triangle = 180°

If an angle is 90°, the sum of the other two angles will be 90°.

Therefore, if R = 120°, it so greater than 90°. The correct options are illustrated above.

The graph that indicates the transformation translating of the parent function to get, y = |x| + 3, created with MS Excel is attached

A function ix transformed when the graph of the function is translated, resized or reflected.

The formula for the transformation of a function, f(x) is y = a·f(b·(x + c)) + d

Where;

a indicates the graph of the function is dilated vertically

b  indicates a dilation horizontally

c indicates a translation horizontally

d indicates a vertical translation

The transformation applied to the parent function is the f(x) is an addition of a term, d = 3, which is a vertical translation

In a vertical translation of the form f(x) ± d

When d > 0, the graph of f(x) is moved up d units to get the graph of f(x) + d

When d < 0, the graph of f(x) is moved down d units to get f(x) - d

The graph of y = |x| + 3, obtained from the parent function, y = |x|, by a transformation of d = +3, therefore, the graph of y = |x| is moved up 3 units to get the graph of y = |x| + 3

If 8 cows can graze a field in 28 days as a result, 14 cows take 12 days to graze the same field.

It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.

It is given that, 8 cows can graze a field in 28 days.

Suppose x is the number of days required to graze the same field.

A proportionality relationship is one that has an inverse proportion. When two quantities are inversely related when one quantity rises, the other falls. The number of hours needed to construct a wall serves as an illustration of inverse proportion. By the inverse proportional relationship,

6:x :: 14:28

x=(28×6) / 14

x=2 × 6

x=12 days

Thus, if 8 cows can graze a field in 28 days as a result, 14 cows take 12 days to graze the same field.

The y-intercept is y = 10, and that is the initial height of the flower in inches.

And the rate of change between n = 1 and n = 5 is:

R = 0.21

For any function y = f(x), the y-intercept is the value that y takes when we evaluate in x = 0.

In this case, we have the exponential function:

g(n) = 10*(1.02)^n

Evaluating in n = 0 we get:

g(0) = 10*(1.02)^0 = 10*1 = 10

The y-intercept is y = 10, and it means that the initial height of the flower is 10 inches.

Now we want to get the average rate of change on the interval [1, 5].

Remember that for a function f(x) the average rate of change on an interval [a, b] is:

R= [ f(b) - f(a)]/(b - a)

In this case we will have:

R = [ g(5) - g(1)]/(5 - 1) = [g(5) - g(1)]/4

Where:

g(5) = 10*(1.02)^5  =11.041

g(1) = 10*(1.02) = 10.200

Replacing that:

R = [11.041 - 10.200]/4 = 0.21

This means that the plant increases about 0.21 inches per day on these 4 days.

Area[tex]{}[/tex]              1     4     9   16   25  36

A quadratic function is a function which is of the general form;

f(x) = a·x² +  b·x  + c, where;

a, b, c, are numbers and the value of 'a' is not zero

The side lengths of a square are the same

The area of a square = Length of Side × Length of side

Therefore;

Area of a square = (Side length)²

The quadratic equation that gives the area, A, from a side length, x, is therefore;

The table in the question can completed using the following calculations

When the side length = 1, The area = 1² = 1

Therefore;

When the area = 4, the side length = √4 = 2

When the area = 9, the side length = √9 = 3

When the side length = 4, the area = 4² = 16

When the area = 25, the side length = √(25) = 5

When the side length = 6, the area = 6² = 36

The statement 'If an integer is negative, its absolute value is also its additive inverse.' is True.

In this question, we have been given a statement 'If an integer is negative, its absolute value is also its additive inverse.'

We know that for any non zero real number 'm', the additive inverse is '-m'

as m + (-m) = 0

We know that the absolute value of any non-zero real number is always positive.

Consider a negative integer -p.

The absolute value of -p is |-p| = p

We can observe that -p + p = 0

-p + |-p| = 0

Therefore, the statement 'If an integer is negative, its absolute value is also its additive inverse.' is True.

The solution to the given system of linear equations is x = -2 and y = -8. That is, (-2, -8).

From the question, we are to determine the solution to the given system of linear equations.

The given system of linear equations is

y = 5x + 2         ---------- (1)

4x - y = 0          ---------- (2)

Substitute equation (1) into equation (2)

4x - y = 0

4x - (5x + 2) = 0

4x - 5x -2 = 0

-x -2 = 0

-2 = x
