Answer:
Ryan is correct.
Step-by-step explanation:
Laura says that the distance between (4, -2) and (4, -7) in the coordinate plane is equal to 1-2-(-7) units.
Here, x-coordinates are same, so the distance between these points is the difference between y-coordinates.
Distance between (4, -2) and (4, -7) = -2-(-7)
= -2+7
= 5 units.
So, Laura is incorrect.
Ryan says that the distance between the points (2, 3) and (-9,3) in the coordinate plane is equal to 2 + 9 units.
Here, y-coordinates are same, so the distance between these points is the difference between x-coordinates.
Distance between (2, 3) and (-9,3) = 2-(-9)
= 2+9
= 11 units.
Therefore, Ryan is correct.
find the value of h
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.
An is climbing down a ladder. Each time he descends four rungs on the ladder, he stops to see how much farther he has to go. Which word in the problem indicates that a negative integer should be used?
Answer:
Descends
Step-by-step explanation:
The word descend is what indicates that a negative integer should be used.
When we talk about height we should be regarding it in increments which makes its integers positive, that is something that increases. But the question says descends, descends means a reduction in height. which is a way of describing height in an opposite or negative direction.

The statement “1cm represents 2m” is the scale of the drawing. It can also be expressed as “1cm to 2m” or “1cm for every 2m.” What do you think the scale tells us?
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

Under which conditions does the commutative property apply to compositions of f(x) and g(x)?
A) when f(g(x)) and g(f(x) are inverse functions
B) when f(g(x)) and g(f(x) are equal for at least one value of x
C) when f(g(x)) and g(f(x) are equal for all values of x
D) when f(g(x)) and g(f(x) are not inverse functions
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.

Jamal borrowed 4000 to buy a used car he borrowed some of the money from a bank that charged 9.2% simple interest and the rest from a friend who charged 12% simple interest. If the total interest for a one year loan was 424.00 how much did jamal borrow at each rate
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

What do you think is going to be the most challenging part of Alg.1 and why?
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.
The third angle of an isosceles triangle is 16 o less than the sum of two equal angles. Find
three angles of the triangle.
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

Is the function even or odd?
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!

Step-by-step explanation:
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

In city A, the temperature rises 9° F from 8am then the temperature drops 8°F from 9am to 10am in city B the temperature drops 1°F from 8am to 9am then the temperature drops 3°F from 9am to 10am write an expression that represents the change In temperature from 8am to 10am for each city. Simplify and interpret each sum. Which expression represents the change in temperature for city A?
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
