Which pairs of angles are supplementary?
1 and 6
5 and 7
5 and 8
2 and 3
Answer:
1 and 6
5 and 7
Step-by-step explanation:
Supplementary angles are 180 degrees and so is a linear pair
1 and 6 add up to 180 degrees meaning they are supplementary. Angle 1 and angle 2 are a linear pair so 180-120=60 which is the degree of angle 1, angle 2 corresponds to angle 6, so angle 1 + angle 6 would equal 180 degrees. (120+60)
5 and 7 are a linear pair which automatically makes them supplementary
The others are vertical angles which don't add up to 180. (120+120=240)(60+60=120)

Write an equation for a line that contains the point (0,4) that is parallel to the
equation below.
y= -7x+1
Step 1: Find the Slope
Parallel lines have the same slope, therefore the slope of our new line is also -7.
Step 2: Find the Y-Intercept
Once we have the slope and a point on the line, we can solve for the y-intercept. Plug in the slope and the given point into slope-intercept form and solve for b.
Slope-Intercept Form: y = mx + b
Slope = -7
Point = (0, 4)
4 = -7(0) + b
b = 4
Step 3: Form the Equation of the Line
Now that we have both the slope and the y-intercept of the new line, all that's left to do is plug those values into slope-intercept form.
Slope-Intercept Form: y = mx + b
m = -7
b = 4
Equation of the New Line: y = -7x + 4
Answer: y = -7x + 4
Hope this helps!
Answer:
y = -7x + 4
Step-by-step explanation:
Given
point = (0, 4)parallel to y = -7x + 1Solving
Slope of new line is also -7y - 4 = -7(x - 0)y - 4 = -7xy = -7x + 4find the measure of angle 8

Suppose that a classmate asked you why (2x + 112 is not (4x² + 1). What is your response to this classmate?
O A. An expression such as (2x + 1)2 is called the square of a monornial. The expression (2x + 1)2 is equal to (22• 2xX1. 1), thus it is not equivalent to
(4x2 +1)
B. The classmate is correct. An expression such as (2x + 1)2 is called the square of a binomial. The expression (2x + 1)2 is equal to (2)?(x} = (132, thus it is
equivalent to (4x + 1)
OC. An expression such as (2x + 1)2 is called the square of a binomial. The expression (2x + 1)2 is equal to (2x+ 1x2x + 1), thus it is not equivalent to
(4x + 1)
OD. An expression such as (2x + 1)2 is called the product of the sum and difference of two terms. The expression (2x + 1)2 is equal to (2x+ 1(2x - 1), thus it is
not equivalent to (4x2 + 1)
+
The given expression is the square of a binomial, such that:
(2x + 1)^2 = 4x^2 + 4x + 1
Then the correct option is C.
Are the expressions equivalent?We want to see if:
(2x + 1)^2
Is equivalent to (4x^2 + 1).
First, this is false, let's prove that.
We have the square of a binomial (2x + 1)^2. Remember the general formula:
(a + b)^2 = a^2 + 2ab + b^2
So if we apply this to our expression we get:
(2x + 1)^2 = (2x)^2 + 2*2x*1 + 1^2 = 4x^2 + 4x + 1
Then, the correct option is C.

Find the length of the third side to the nearest tenth
Answer: ≈ 1.4.
Step-by-step explanation: To find the hypotenuse of a triangle (the longest side of a triangle), you need to add the legs (the two sides of the triangle that are not the hypotenuse). You need to have ^2 when adding each leg. For example, both legs are 1 so when you're adding them, the equation should look like this--> 1^2 + 1^2. Then, once you find the answer to that, you need to find the square root of the answer. The work is done below:
1^2 + 1^2 = 2.
√2 ≈ 1.41421356 or ≈ 1.4.
Therefore, your answer is ≈ 1.4.

Consider the linear equation y = 5x – 4.
1. Provide 3 ordered pairs that are solutions to this linear
equation.
2. Test the point (-5, -29) to see if it is a solution to the
linear equation.
Be sure to show all work.
Answer:
(0,-4), (2,6), and (4, 16) are solutions to this equation.
Yes the point (-5,-29) is a solutions
Step-by-step explanation:
(-5,-29) is a solution because if you plug in -5 for x, y will equal to the y in the ordered pair.
a) Three ordered pairs (0, -4), (2, 6), and (-3, -19) that are solutions to the linear equation y = 5x - 4.
b) We verified that the point (-5, -29) is a solution to the equation by substituting its x and y values and getting a true statement.
a. To find ordered pairs that are solutions to the linear equation y = 5x - 4, we can simply substitute different values of x into the equation and calculate the corresponding y-values.
Let's choose three different values for x and calculate the corresponding y-values:
When x = 0: y = 5(0) - 4 = -4
So, the ordered pair is (0, -4).
When x = 2: y = 5(2) - 4 = 6
So, the ordered pair is (2, 6).
When x = -3: y = 5(-3) - 4 = -19
So, the ordered pair is (-3, -19).
b. To test whether the point (-5, -29) is a solution to the linear equation y = 5x - 4, we need to check if substituting x = -5 into the equation gives us y = -29.
Let's do the calculation:
y = 5(-5) - 4
y = -25 - 4
y = -29
Since y = -29 when x = -5, the point (-5, -29) is indeed a solution to the linear equation.

How much faster, in miles per minute, does Zoe bike in the first 5 minutes (0 – 5) of her trip compared to the last 5 minutes (20 – 25) of her trip?
A. 0.1 mile/minute faster
B. 0.3 mile/minute faster
C. 0.4 mile/minute faster
D. 0.5 mile/minute faster
Using proportions, it is found that the correct option regarding how much faster she is in the first 5 minutes compared to the last 5 is given by:
B. 0.3 mile/minute faster
What is a proportion?A proportion is a fraction of a total amount
Researching the problem on the internet, it is found that on the first 5 minutes, she bikes 2 miles, hence the ratio is:
r1 = 2/5 = 0.4 miles/minute.
On the last 5 minutes, she bikes 0.5 miles, hence:
r2 = 0.5/5 = 0.1 miles/minute.
The difference is given by:
D = 0.4 - 0.1 = 0.3 miles/minute.
Which means that option B is correct.
