B 125
C 19
D 55
Answers
The value of x in the angles is 19.
How to find angles in intersecting lines?When lines intersect, angle relationships are formed such as vertically opposite angles, adjacent angles etc.
Therefore, let's find the value of x in the intersecting lines.
Hence,
7x - 8 = 6x + 11 (vertically opposite angles)
Vertically opposite angles are congruent and they share the same vertex point.
Hence,
7x - 8 = 6x + 11
subtract 6x from both sides of the equation
7x - 8 = 6x + 11
7x - 6x - 8 = 6x - 6x + 11
x - 8 = 11
add 8 to both sides of the equation
x - 8 + 8 = 11 + 8
x = 19

Are the graphs of the equations parallel, perpendicular, or neither?x -3y = 6 and x - 3y = 9
Answers
The equation of a line in Slope-Intercept form, is:
[tex]y=mx+b[/tex]Where "m" is the slope of the line and "b" is the y-intercept.
By definition:
- The slopes of parallel lines are equal and the y-intercepts are different.
- The slopes of perpendicular lines are opposite reciprocals.
For this case you need to rewrite the equations given in the exercise in Slope-Intercept form by solving for "y".
- Line #1:
[tex]\begin{gathered} x-3y=6 \\ -3y=-x+6 \\ y=\frac{-x}{-3}+(\frac{6}{-3}) \\ \\ y=\frac{x}{3}-2 \end{gathered}[/tex]You can identify that:

Answer the questions below about the quadratic function.g(x) = 3x² + 12x+8Does the function have a minimum or maximum value?MinimumMaximumWhere does the minimum or maximum value occur?x =0What is the function's minimum or maximum value?
Answers
Plot the function on the graph.
From the graph it can be observed that graph of function opening upwards and it has minimum value at x = -2.
Thus function has minimum value.
The minimum value of the function occurs at x = -2. So mimimum value of function occurs at x = -2.
The value of the function at x = -2 is -4. So function's minimum value is -4.

Which equation is equivalent to - 2x + 5 - 3x = 5x + 25?A. -5 = -30B. -6x + 5 = 5x + 25C. - 10x = 20D. 20x - 5 = 25
Answers
In order to determine which is the equivalent equation, simplify the given expression:
-2x + 5 - 3x = 5x + 25 simplify like terms left side
-2x - 3x + 5 = 5x + 25
-5x + 5 = 5x + 25 subtract 5x both sides and subtract 5 both sides
-5x - 5x = 25 - 5 simplify both sides
-10x = 20
Hence,the equivalent expression is -10x = 20
Two planes, which are 2320 miles apart, fly toward each other. Their speeds differ by 80 mph. If they pass each other in 4 hours,what is the speed of each?Step 1 of 2: Use the variable x to set up an equation to solve the given problem. Set up the equation, but do not take steps to solve it.
Answers
Given the word problem, we can deduce the following information.
1. Two planes, which are 2320 miles apart, fly toward each other.
2. Their speeds differ by 80 mph.
3. They pass each other in 4 hours.
To find the speed of each plane, we use the formula:
distance = (rate)(time)
Since they are flying towards each other, the sum of both speeds is 2x+80. So,
distance = (rate)(time)
2320 miles = (2x+80 mph)(4 hrs)
Thus, the equation to solve this is:
2320 = (2x+80)(4)

The equation 3x + 2y = 120 models the number of passengers who can sit in a train car, where isthe number of adults and y is the number of children. Explain what the 2- and y-intercepts mean.
Answers
Explanation:
Given the equation that models the number of passengers who can sit in a car expressed as 3x + 2y = 120
x is the number of adults
y is the number of children
The x-intercept is the point where y is zero i.e. the number of adults when there is no number of children.
when y = 0
3x + 2(0) = 120
3x = 120
x = 120/3
x = 40
This means that there will be 40 adults if there are no children
The y-intercept is the point where x is zero i.e. the number of children when there is no number of adults.
when x = 0
3(0) + 2y = 120
2y = 120
y = 120/2
y = 60
This means that there will be 60children if there are no adults

Answers
The average rate of change is given by the rate of change of both variables.
"Rate" refers to a division. We want to divide the change of y, Δy, by the change of x, Δx:
Δy/Δx
("Δ" means "change").
We want to analyze the change over the interval 3 ≤ x ≤ 9.
Step 1: change of x (Δx)The change from x = 3 and x = 9 is
Δx = 9 - 3 = 6
Step 2: change of y (Δy)We observe the right column of the table. When x = 3, y = 28 and when x = 9, y = 4.
The change from y = 28 to y = 4 is
Δy = 4 - 28 = -24
Step 3: rate of changeThen, the average rate of change is:
Δy/Δx = -24/6 = -4

Answers
In general, given a quadratic function,
[tex]\begin{gathered} f(x)=ax^2+bx+c \\ a,b,c\rightarrow\text{ constants} \end{gathered}[/tex]The end behaviors of each end of the function are given by the limits of f(x) when x approaches +/-infinite.
Therefore,

Hence, the answer is True, the statement is True.An online company is advertising a mixer on sale for 25 percent off the original price for 260.99. What is the sale price for the mixer . Round your answer to the nearest cent , if necessary.
Answers
$195.74
1) We can find out the sale price for the mixer, by writing out an equation:
In the discount factor 1 stands for 100% and 25% =0.25
2) So we can calculate it then this way:
[tex]\begin{gathered} 260.99(1-0.25)= \\ 260.99\text{ (0.75)=}195.74 \\ \end{gathered}[/tex]Note that we have rounded it off to the nearest cent 195.7425 to 195.74 since the last digit "4" is lesser than 5, we round it down.
3) So the price of that mixer, with a discount of 25% (off) is $195.74
Alternatively, we can find that price by setting a proportion:
0.25 = 1/4
Writing out the ratios we have:
260.99 --------- 1
x ---------------- 1/4
Cross multiplying it we have:
260.99 x 1/4 = x
x=65.2475
Subtracting that value 25% (65.2475) from 260.99 we have:
260.99 - 65.2475 =195.7425 ≈ 195.74
