When Kenneth opened her account, her account balance was 30.

A function is an expression that assigns each input value, say x, a unique output value, say y. Mathematically, a function can be represented as-

F(x) = x + a

Here, we are given that Kenneth's bank account is modeled by the following equation-

f(x) = 13x + 30

here, x =  number of weeks

and  f(x) = total amount

When Kenneth must've opened his account, the number of weeks would've been zero.

⇒ x = 0

Substituting the value of x = 0 in f(x), we get-

f(0) = 13(0) + 30

f(0) = 0 + 30

f(0) = 30

Thus, when Kenneth opened her account, her account balance was 30.

Answer:

Step-by-step explanation:

Because 32+8=40

32

- 08

-----

40

Answer: -24 feet

Step-by-step explanation: ascending is rising so you would subtract feet, which in this case is 8 feet. after that you would consider that since she is underground the feet would be negative because she is below ground level which is zero. once you subtract it then you would get a grand total of -24 feet or 24 feet below the earth's surface but more than likely the answer would be -24 ft.

Answer:

C) corresponding angles

Step-by-step explanation:

AE is a transversal that crosses two parallel lines. Notice Angle ABC and BED are on the same corner. Hence, they are corresponding angles

Using translation concepts, the series of transformations that shows that pentagon A is congruent to pentagon B is:

B. Rotate pentagon A 90° clockwise about the point (1, 1), reflect it over the x-axis, and translate it 3 units to the left.

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

In this problem, we have that the Pentagons have different orientations, meaning that it was rotated, eliminating options A and D.

For the vertices to reach the position they reached in Pentagon B, there had to be a shift left, and before the shift left, the Pentagon must have been entirely at the fourth quadrant, meaning that it was reflected about the point (1,1), and option B is correct.

Ruguru need $15 more to rent a car for 3 days.

Given,

Number of days Ruguru wants to rent a car = 3 days

The amount Ruguru has with him = $115

The cost for the rental of the car:

C = 25 + 35D

Where,

D is the number of days

Now,

Lets find the total rent of the car for 3 days

C = 25 + 35D

C = 25 + 35 × 3

C = 25 + 105

C = 130

The total rent of a car for 3 days is $130

We have to find the amount needed by Ruguru to rent a car for 3 days.

That is,

Total rent - Amount Ruguru has = Amount needed

130 - 115 = 15

Therefore,

Ruguru need $15 more to rent a car for 3 days.

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. The probability of an occurrence is a number between 0 and 1, with 1 representing certainty and 0 representing impossibility. The higher the likelihood of an event, the more likely it is to occur. A straightforward illustration is tossing a fair (impartial) coin. Since there are no other conceivable outcomes and the coin is fair, the odds of both the possibilities, "heads" and "tails," are equally likely to occur. As a result, the probability of either occurrence is half.

Time is the continuous flow of existence and the events that take place in what appears to be an unbreakable sequence from the past, present, and forward into the future. Time is often referred to be a fourth spatial dimension in addition to the three others.

Philosophers, theologians, and scientists have long considered time to be an important subject of study, but they have never been able to agree on a definition of time that can be used across all of these fields without becoming circular. However, a wide range of fields, including business, industry, sports, the sciences, and the performing arts, all include some form of the concept of time into their own measurement schemes.

when we take x = 9.33, the equation becomes true, which means that the linear equation has one solution.

Here we have the following linear equation:

15 + 3*(2x - 9) = 44

And we want to see if this has a solution, it means that there is a value of x such that the equation becomes true. Let's see that.

To do it, we need to isolate the variable, x, in one of the sides of the equation.

Expanding the product we get:

15 + 3*2x - 3*9 = 44

Moving the terms without x to the right side:

15 + 6x - 27 = 44

6x = 44 + 27 - 15 = 56

Now we can divide both sides by 6 so we get:

x = 56/6 = 9.33

So, when we take x = 9.33, the equation becomes true, which means that the linear equation has one solution.

Answer:

Using linear functions, the system of inequalities that matches the graph is given by:

A linear function is modeled by:

y = mx + b

In which:

Given two points, the slope is given by change in y divided by change in x. For the first line, the points are:

(-1, -3) and (0,0).

Hence the slope is:

m = (0 - (-3))/(0 - (-1))

m = 3.

When x = 0, y = 0, hence the y-intercept is of b = 0 and the line is given by:

y = 3x.

Everything to the right of the solid line is shaded, hence the values that are equal(line is solid) or greater than the line compose the inequality, as follows:

y ≥ 3x.

For the second line, the points are:

(-2,3) and (1,-3).

Hence the slope is:

m = (-3 - 3)/(1 - (-2)) = -6/3 = -2.

Then:

y = -2x + b.

When x = -2, y = 3, hence:

3 = -2(-2) + b

b = -1.

Hence the line is:

y = -2x - 1.

Everything to the right of the dashed line is shaded, hence the inequality is:

y > -2x - 1.
