Answer:

2000 ; 2000

Step-by-step explanation:

Given the following :

Total amount borrowed = 4000

Total interést paid = 424

Simple interést = (principal * rate * time)

Rate 1 = 9.2% = 0.092

Rate 2 = 12% = 0.12

Let amount borrowed at 9.2% = x

Amount borrowed at 12% = y

x + y = 4000 - - - - (1)

x * 0.092 + y * 0.12 = 424

0.092x + 0.12y = 424 - - - - (2)

from (1):

x = 4000 - y

0.092(4000 - y) + 0.12y = 424

368 - 0.092y + 0.12y = 424

368 + 0.028y = 424

0.028y = 424 - 368

0.028y = 56

y = 56/0.028

y = 2000

x + y = 4000

x = 4000 - 2000

x = 2000

Answer:

The correct option is;

C) When f(g(x)) and g(f(x)) are equal for all values of x

Step-by-step explanation:

To have commutative property is to have the property to move around or change position, as such the commutative property is the property concerns the changing of the positioning of items

The commutative property for addition is a + b = b + a while the commutative property for multiplication is a×b = b×a

For functions , the commutative property can therefore, be expressed as follows;

Commutative property of f(x) and g(x) gives f(g(x)) = g(f(x)) for all values of x.

Step-by-step explanation:

I got it right on edge2021

The order of differences ordered from least to greatest

Pang, Ruben, Adela, Tony.

The arranging of numbers from least to largest is known as ascending order. For instance, the digits 3, 15, 28, and 49 are listed in ascending order.

Given:

             Age Difference

Adela: 0.75 year

Tony:  1 1/10 years = 11/10= 1.1 year

Pang: –0.8 year

Ruben: -1 / 2 year = -0.5 year.

So, the differences ordered from least to greatest

-0.8 < -0.5 < 0.75 < 1.1

Hence, Pang, Ruben, Adela, Tony.

Answer:

For City A, the expression for temperature change is 9 + (-8)

The amount the temperature changes for City A = 1°F

For City B, the expression for temperature change is -1 + (-3) = -4°F

The amount the temperature changes for City B = -4°F

Step-by-step explanation:

The given information are;

In City A, the temperature rise from 8 am to  9 am = 9°F

In City A, the temperature drop from 9 am to  10 am = 8°F

In City B, the temperature drop from 8 am to  9 am = 1°F

In City B, the temperature drop from 9 am to  10 am = 3°F

The expression for that represents the temperature change from 8 am to 10 am is therefore;

For City A

Temperature change from 8 am to 10 am are

8 am to  9 am = +9°F

9 am to  10 am = -8°F

Sum, change from 8 am to 10 am = 9 + (-8) = 1°F

For City B

Temperature change from 8 am to 10 am are

8 am to  9 am = -1°F

9 am to  10 am = -3°F

Sum, change from 8 am to 10 am = -1 + (-3) = -4°F

Answer: The value of h is -1.

Step-by-step explanation:

The function F(x) = ║x║ has been shifted 1 unit to the right. H in this case represents if the function has been shifted to the right or to the left. If the function is being shifted to the right then H is negative and if the function is shifted to the left, x is positive. In this case the value of h  is -1.

Answer:

A scale is a way to resize drawings or figures to make them fit into a particular size.

Step-by-step explanation:

In 2D drawing or diagrams, a  scale factor greater than 1 enlarges the object, while a scale factor between 0 and 1 shrinks the objects, also using a scale factor of 1 changes nothing or leaves the drawing the way it is.

Furthermore, scales are represented in ratio form 1:2, telling us that say 1cm in the virtual environment or paper represents 2km in reality

Answer:

[tex]f(\theta)=\cos(\theta)[/tex] is an even function.

Step-by-step explanation:

Recall when it means when a function is even or odd. An even function has the following property:

[tex]f(-x)=f(x)[/tex]

And an odd function has the following property:

[tex]f(-x)=-f(x)[/tex]

So, let's test some values for cos(x).

Let's use π/3:

[tex]f(\pi/3)=\cos(\pi/3)[/tex]

From the unit circle, was can see that this is 1/2 (refer to the x-coordinate).

Now, let's find -π/3. This is the same as 5π/3. Thus:

[tex]f(-\pi/3)=\cos(-\pi/3)[/tex]

And again from the unit circle, we can see that this is 1/2.

Therefore, despite the negative, the function outputs the same value.

Cosine is an even function.

Notes:

Cosine is an even function and sine is an odd function. It's helpful to remember these as they can help you solve some trig problems!

0.75x -5 = 0.583333333333...

Answer:

x = 7.4444

Step-by-step explanation:

3/4 x - 5 = 7/12

3x/4  - 5 = 7/12

3x/4 = 7/12 + 5

3x/4 = 7/12 + 60/12

3x/4 = 67/12

3x = 4*67/12

3x = 268/12

3x = 22.3333

x = 22.3333/3

x = 7.4444

Check:

3*7.4444/4 - 5 = 7/12

5.58333 - 5 = 0.58333

Answer:    49°, 49°, 82°

Step-by-step explanation:

Let x represent the base angles

then 2x - 16 is the vertex angle.

Triangle Sum Theorem states that the sum of the angles is 180°

(x) + (x) + (2x - 16) = 180

                 4x - 16 = 180

                       4x = 196

                         x = 49

Base angles: x = 49

Vertex angle: 2(49) - 16 = 82

Answer:

I think Factoring is going to be the most challenging part of Alg.1 because it seems like there are a lot of steps before finding the answers.

Explanation:

When I took algebra I, the most difficult part for me was inequalities.

I had been used to linear equations and even quadratic equations, where the operative rule is "keep the equal sign sacred" (whatever you do to one side must also be done to the other side). Once I figured out that multiplying or dividing inequalities by a negative number reverses the comparison, I was good to go.

__

These days, algebra I also includes a good dose of statistics. That seems to trip up a number of people, including me. The main thing, I think, is to stay clear on the definitions, and whether you're talking about a population or a sample. A lot of the math is easily handled by a graphing calculator or spreadsheet, so familiarity with the use of those is a great bonus (almost required).

__

You will be better equipped to go into algebra I if you have memorized multiplication tables, rules of divisibility, some mental math procedures, and squares and cubes of small integers (square ≤ 20^2, cubes ≤ 10^3). This will help immensely when it comes to factoring. Similarly, you need to be familiar with arithmetic involving decimals, fractions, and mixed numbers. Numbers in one form should offer you no more challenge than numbers in any other form.

__

A big challenge for many people is the fact that math builds on previous learning. If you don't learn the early stuff well, and practice it a lot, then you will find you have difficulty drawing on that knowledge to make the later stuff easier. It's NOT a "test and forget" sort of deal. It's a "remember this forever" sort of deal.
