b.
y = 3x + 7, y = x / 3 + 11
c.
y = − 3x + 7, y = x / 3 + 11

Answer:
The line pairs that are pendicular are shown in option c.
c. y = − 3x + 7, y = x / 3 + 11
Step-by-step explanation:
Perpendicular lines have slopes that are the negative inverse of each other. For example, a line with slope of 5 would have a line perpendicular to it if the second line has a slope of -(1/5) [the negative inverse of +5].
Cmpare the slopes of each pair of linear equations:
a. -3 and 3 The negative inverse of -3 would be (1/3), not 3. These lines are not perpendicular.
b. 3 and (1/3). The negative inverse of 3 would be -(1/3), not (1/3). These lines are not perpendicular.
c. -3 and (1/3). The negative inverse of -3 would be (1/3). These lines are perpendicular.
d. -3 and (-1/3). The negative inverse of - 3 would be (1/3). These lines are not perpendicular.

Step-by-step explanation:
1. Question: 2x+1=9
2. Subtract 1 from the 9
Answer to step 2: 2x=8
3. Divide 8/2 (4x2)
4. Answer: x=4
Answer: X= 4; look below for the explanation of algebra tiles
Step-by-step explanation: First, we need to determine the value of x. We can use the rule of inverse operations. So, the opposite of addition is subtraction, and the opposite of multiplication is division. Now, using that, we start with the inverse operations of 1 + 9. That'd be 9 - 1. So, that's 8. Now, according to the order of inverse operations, we divide the 2 by 8. So, 8 divided by 2 is 4. Therefore x = 4.
Now, using the tiles, we need to get 8 tiles, + 1 tile, which should get you your answer. I hope this helped!
why is the product of the circumradius and the area of the triangle equal to the product of the sides of the triangle
Answers
Answer:
It isn't.
The correct relation is 4r·Area = abc.
Step-by-step explanation:
You want to show the relation between the product of triangle side lengths and the product of the triangle area and the radius of the circumcircle.
Triangle areaThe area of the triangle in the attached diagram can be found by ...
Area = 1/2(bc)sin(α)
Side lengthThe inscribed angle theorem tells you the measure of the arc subtended by an inscribed angle is twice the measure of the inscribed angle. That means the opposite chord will be twice the length of the product of the radius and the inscribed angle value:
a = 2r·sin(α)
Circumradius productThe product of the circumradius and the area of the triangle is ...
r·Area = r·(1/2)(bc)sin(α) = 1/4(bc)(2r·sin(α)) = 1/4abc
Without the fractions, the relation is ...
4r·Area = abc
__
Additional comment
As a simple example, consider a 3-4-5 right triangle. The area of the triangle is ...
A = 1/2(3)(4) = 6
The circumradius is half the length of the hypotenuse, r = 5/2.
The relation of interest is ...
4r·Area = abc
4(5/2)(6) = 3·4·5
60 = 60 . . . . . . . . . . as expected
This could be a very simple way to find the circumradius of a triangle.

What should be done to these equations in order to solve a system of equations by elimination?
Answers
To solve the problem of a system of equations by elimination, we can start with both equations in standard form. Then we can decide which variable will be easier to eliminate.
How can we decide? We want to have the coefficients of any one of the variables be opposites so that we can put the equations together and eliminate that variable.
To solve a simultaneous equation by using the elimination method, you eliminate any one variable first.
Before you can do that, the coefficient of one of the variables in the two equations must be the same.
From the given questions, for the coefficient of one variable in the two equations to be the same, we multiply the first equation by 3.
If we can do this, the coefficient of Y in the two equations will now be 3.

A bar over a digit in a decimal number, such as 0.133 with a bar over the 3, indicates that the number is a repeating decimal. In this case, 0.133 is a repeating decimal and the digit 3 is repeating infinitely.
What is repeating decimal?A repeating decimal is a decimal number whose digits are periodic and repeat infinitely. They are also called recurring decimals. For example, 0.333... is a repeating decimal, with the digit 3 repeating indefinitely. The same goes for 0.666... and so on. They can also be represented in the form of a fraction, where the numerator is the repeating decimal and the denominator is a power of 10 with a 1 followed by as many zeroes as the number of digits in the repeating block. Repeating decimals can also be represented with a bar over the repeating block of digits, for example 0.133 with a bar over the 3, indicating that the digit 3 is repeating infinitely. It's also written as 0.133(3) where (3) means the repeating decimal. Another way is to use a dot above the repeating digit.To learn more about decimal refer:

Solve the equation t − 3 = 17 for t.

I already searched the question and none of the answers I saw were an option.
Answers
The equation can be solved by adding 3 to both sides of the equation.
Solve the equation t − 3 = 17 for t?To solve the equation t − 3 = 17, we need to add 3 to both sides of the equation. Doing so, we get t = 17 + 3 = 20. Therefore, the value of t is 20.In this case, the variable is t. The equation t - 3 = 17 has 3 subtracted from t on the left side, so to isolate t, we must add 3 to both sides to make the equation equal. Once we do this, we are left with t = 20.The equation t − 3 = 17 is an equation with a single variable, t.The equation t - 3 = 17 is a simple algebraic equation that can be solved by performing the inverse operation of subtraction. To solve this equation, we must first add 3 to both sides of the equation.Therefore, the solution to the equation t - 3 = 17 is t = 20.The equation can be solved by adding 3 to both sides of the equation. When 3 is added to the left side of the equation, it cancels out the -3, leaving just t. When 3 is added to the right side of the equation, it increases the value of the right side from 17 to 20. Therefore, the equation t − 3 = 17 can be solved by adding 3 to both sides, which results in the equation t = 20.This means that the value of t is 20.To learn more about the value of the unknown variable refer to:

The circumference of a circle is 125.6 millimeters. What is the circle's radius?
Answers
Answer:
20 millimeters.
Step-by-step explanation:
To find the radius of a circle with circumference, you must divide the circumference by pi (3.14).
After dividing the circumference by pi, you now have the diameter of the circle.
Secondly, to get the radius, divide the quotient (the diameter) by 2.
The quotient is the radius of the circle.
----------------------------------------------------------------------------------------------------------------
Now, I will repeat these steps using the circumference of 125.6 millimeters.
125.6 ÷ 3.14 = 40.
40 ÷ 2 = 20.
Therefore, 20 millimeters is the radius of this circle.
The circle's radius is mathematically given as
r=20
What is the circle's radius?Question Parameter(s):
The circumference of a circle is 125.6 millimeters.

Which inequalities represent Susan's weekly goal of earning money?
Answers
Inequalities represent Susan's weekly goal of earning money are:
c + e ≤ 20
15c + 10e ≥ 240
What is an inequality?The term "inequality" in mathematics refers to a connection between two expressions or values that is not equal to each other. Inequality originates from an imbalance, thus. The majority of the time, size comparisons between two numbers on the number line are made.
The most notable instances of social inequality include those related to health care, social class, gender inequality, and wealth disparity. Comparatively speaking, some people in the healthcare system receive better and more skilled care. For these services, they are also likely to pay more.
Given that,
Susan earns $10 per hour tutoring elementary students in math.
She also earns $15 per hour cleaning in the library.
Her goal each week is to earn at least $240 while working not more than 20 hours.
Thus, the equation of inequality:
c + e ≤ 20
15c + 10e ≥ 240

c represent the number of hours Susan works in one week cleaning the library.
