The most appropriate choice for slope will be given by -
1) Initially, as x increases, y also increases
2) Slope of the graph between x = 3 and x = 5 is 2
3) Slope of the graph between x = 5 and x = 9 is -1
4) Greatest value of y is y = 4 and it occurs when x = 5
What is slope of a line?
Slope of a line is equal to the tangent of the angle that the line makes with the positive direction of x axis.
If [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, slope = tan [tex]\theta[/tex]
Suppose [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex]be two points on a line then the slope of the line is calculated by the formula
slope = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Here,
1) Initially, as x increases, y also increases
2) Slope of the graph between x = 3 and x = 5 = [tex]\frac{4 - 0}{5 - 3}[/tex]
= [tex]\frac{4}{2}[/tex]
= 2
3) Slope of the graph between x = 5 and x = 9 =
[tex]\frac{4 - 0}{5 - 9}\\-\frac{4}{4}\\-1[/tex]
4) Greatest value of y is y = 4 and it occurs when x = 5

Carlos is a receptionist at a law firm. He spends 2 minutes routing each phone call as it

Write an equation that shows how the total number of minutes Carlos spends routing calls, y,

Answers
The linear equation that relates the time with the number of calls is:
Y = (2min)*X
How to write the linear equation?We know that Carlos is a receptionist at a law firm. We know that he spends 2 minutes routing each phone as it comes in.
So if we define Y as the number of minutes Carlos spends routing calls, and X as the number of calls that come in, the linear equation resulting will be:
Y = (2min)*X
By evaluating that linear equation in the correspondent value of X, we will get the time it took to connect those calls.

Which graph best represents -2y =4x - 8 ? ASAP like RIGHT NEOW
Answers
The equation - 2y = 4x - 8 in slope intercept is y = - 2x + 4.
Consider the function,
- 2y = 4x - 8
The equation of a line in slope intercept form is y = mx + b where m is the slope and b is the y-intercept.
So,
- 2y = 4x - 8
y = - 2x + 4
Now,
When x = 0
y = - 2(0) + 4 = 4
When x = 1,
y = - 2(1) + 4 = 2
When x = 2,
y = - 2(2) + 4 = 0
When x = - 1,
y = - 2( - 1 ) + 4 = 6
When x = - 2,
y = - 2( - 2 ) + 4 = 8
When x = 3,
y = - 2( 3 ) + 4 = - 2
So, the point on the graph are ( 0, 4 ), ( 1, 2 ), ( 2, 0 ), ( 3, - 2), ( - 1, 6 ), ( - 2, 8 ).
Therefore, the graph of the function is:

Which is the BEST next step for solving the inequality shown?

A. Subtract x from both sides of the inequality.
B. Subtract 7 from both sides of the inequality.
C. Combine the like terms on the right-hand side of the inequality.
D. Add 1 to both sides of the inequality.
Answers
The next step is Add 1 to both sides of the inequality.
what is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
For example, In the 12U Softball division, Olivia gets chosen. What is Olivia's age? Olivia's age is unknown to you because the word "equals" is missing. However, since you are aware that she should be under or equal to 12, you can write Olivia's Age ≤ 12. This is a real-world example of an inequality.
Given:
14 > x + 7(x+1) -1
14 > x + 7x + 7 -1
now, Add 1 to both sides of the inequality.
14+ 1 > x+ 7x + 7- 1 +1
15> x+ 7x +7
again, Subtract 7 from both sides of the inequality.
15 - 7 > x+ 7x + 7 -7
8 > x+ 7x

the framed picture is 64 inches. Find the width of the frame. x.
Answers
Answer:
x=6in
Step-by-step explanation:
to find x, we need to figure out what side a(8in) + side b(12in)
8+12=20. what we need to be is 32 because 32 is half of 64, and we did half of the perimeter by only adding side b to side a, instead of adding them both twice.
the distance from 20 to 32 is 12.
x=6 because you have to add 6 to side b, and side a, and you will get 14in and 18in. 14+18=32
the reason i said, "the distance from 20 to 32 is 12." is because if you divide it by 2, you get the answer. this works is because we are dividing into two sides, like i said, so 12/2=answer

In the third option, we can see the same slope in the two functions so is parallel

The value of the base in the given triangle is 22.96.
What is a triangle?Three edges and three vertices make up the three sides of a triangle, which is a three-sided polygon in geometry. The fact that a triangle's internal angles can be added up to equal 180 degrees is its most significant characteristic. Triangle's angle sum property is what this characteristic is known as.
We have given to find m, we will use cosine rule
cos ∅ = base/hypotenuse
Here ∅ = 35°
Base = m
Hypotenuse = 28
lets substitute the values and we get,
⇒ cos 35° = m/28
⇒ m = cos 35° × 28
⇒ m = 0.82 × 28 ( cos 35° = 0.82)
⇒ m = 22.96
Thus, the value of the base in the given triangle is 22.96.

Part 1
Point B has coordinates (5,1). The x-coordinate of point A is −3. The distance between point A and point B is 10 units. What are the possible coordinates of point A?
Answers
The possible coordinates of the point A is (-3, -5) and (-3, 7)
How the coordinates of point A can be calculated?The given parameters are:
Point B = (5, 1)Distance between the two points, D = 10 unitsx-coordinate of point A = −3 i.e. A = (-3, y)The distance between any two points is calculated as
D = √[(x₁ - x₂)² + (y₁ - y₂)²]
Substitute the known values in the above equation
So, we have
10 = √[(-3 - 5)² + (y - 1)²]
Evaluate
100 = 64 + (y - 1)²
Evaluate the like terms
(y - 1)² = 36
Take the square roots
y - 1 = ±6
This gives
y = 1 ± 6
So, we have
y = -5 and 7
Hence, the value of point A are (-3, -5) and (-3, 7)

4. Name a point non-coplanar to plane K.
Answers
Considering the given line and plane, it is found that:
1. Points E and F are colinear to point D.
2. Another name for line p is line AB, as these two points form the line.
3. The intersection of line r and plane K is at point X.
4. One point non-coplanar to plane K is of W.
Item 1Two points are colinear if they belong to the same line. In the context of this problem, points D, E and F belong to line q, hence points E and F are colinear to point D.
Item 2
Given two points, there is only one line that can pass through these points. Line p in this problem is composed by points A and B, hence the line can also be called line AB.
The intersection of a plane and a line is at a single point, and the point of line r that is coplanar to plane K is point X, hence it is the intersection of the line with the plane.
Item 4
A point is coplanar to a plane when the point belongs to the plane. In this problem, points W and Y do not belong to plane K, hence both are non-coplanar to plane K.

Please also give 1 example for each law.
Answers
Law of Syllogism
The law of syllogism, also called reasoning by transitivity, is a valid argument form of deductive reasoning that follows a set pattern. It is similar to the transitive property of equality, which reads: if a = b and b = c then, a = c.There are also three parts involved in the law of syllogism, and each of these parts is called a conditional statement. A conditional statement has a hypothesis, which follows after the word if, and it has a conclusion, which follows after the word then. A letter is used to represent each phrase of the conditional statement. Let me introduce the pattern, and then we can look at some examples. Statement 1: If p, then q. Statement 2: If q, then r. Statement 3: If p, then r. Statements 1 and 2 are called the premises of the argument. If they are true, then statement 3 must be the valid conclusion.Law of Detachment
The law of detachment states that if a conditional statement is true and its antecedent is true, then the consequence must also be true.There are endless examples both in mathematics and beyond of the law of detachment. One example is a coffee shop that gives a free drink to every 25th customer. As a conditional statement, this is “If someone is the 25th customer, then they get a free drink. ”Thus, if you are the 25th customer, you know you will get a free drink. Likewise, if your friend is the 25th customer, you know he will get a free drink.Sources: https://www.storyofmathematics.com/law-of-detachment/
