Below are two parallel lines with a third line intersecting them
X=|____|°
Answer:
x = 80°
Step-by-step explanation:
From the picture attached,
Two lines are parallel and third line (transversal) is intersecting these lines at two different points.
m(∠x) = 80° [Exterior alternate angles are equal in measure]
Therefore, x° = 80° is the answer.

Hector bought 6 bottles of juice for $2.40. At that rate, what is the cost of: 1 bottle, 3 bottles, 5 bottles?
Answer:
1 bottle: $0.40
2 bottle: $1.20
5 bottle: $2.00
Step-by-step explanation:
Answer:
Cost of one is 40 cents. Cost of three $1.20. Cost of five $2.00.
Step-by-step explanation:
Divide: 2.40 divided by 6= .4
.4 times 1=.4=.40= 40 cents
.4 times 3=1.2=1.20= $1.20
.4 times 5=2=2.00= $2.00

The volume of a sphere can be found using the formula V = πr . If the sphere has a diameter of 10x y z mm, what is the volume of the sphere in cubic millimeters?
Answer:
500πx³y³z³
Step-by-step explanation:
Volume of a sphere = 4πr³
r is the radius of the sphere
Given
Diameter of the sphere = 10xyz mm
Radius = diameter/2
Radius = 10xyz/2
Radius = 5xyz
Substitute the radius into the formula
Volume of the sphere = 4π(5xyz)³
Volume of the sphere = = 4π(125)x³y³z³
Volume of the sphere = 500πx³y³z³
Hence the volume of the sphere is 500πx³y³z³ mm³
Timothy purchased a computer for $1000. The value of the computer depreciates by 20% every year.
Answer:
We can apply the straight-line method to solve for the value of the computer every year.
Step-by-step explanation:
Step one:
What is depreciation?
It can be defined as the loss of value of a commodity.
In this problem, the percent depreciation is given as 20% which means that 20% of the worth of the computer is lost every year.
We are told that the computer cost is $1000
let the number of years taken for the computer to depreciate be x
Step two:
Say we want to find the value of the computer after 1 year, the value of the computer will be
Value of computer= 1000-20/100*1000
Value of computer= 1000-0.2*1000
Value of computer= 1000-200
Value of computer= $800
Step three:
For the second year, the value will be
Value of computer= 800-20/100*800
Value of computer= 800-0.2*800
Value of computer= 800-160
Value of computer= $640
Answer:
This situation represents exponential decay. The rate of growth or decay, r, is equal to 0.2. So the value of the computer each year is 80% of the value in the previous year. It will take 3 years for the value of the computer to reach $512.

f(x) = |x|
g(x) = |x+9| - 5
We can think of g as a translated (shifted) version of f.
Complete the description of the transformation.
Use nonnegative numbers.
The transformed function g(x) = |x + 9| - 5 has a vertex at (- 9, - 5).
What is an absolute value function?We know the absolute value function of the modulus function always outputs a positive value irrespective of the sign of the input.
In piecewise terms | x | = x for x ≥ 0 and | x | = - x for x < 0.
Given, The parent function is f(x) = |x|.
Now, The transformed function g(x) = |x + 9| - 5 is shifted x + 9 = 0 ⇒ x = - 9 units along the x-axis and - 5 units along the y-axis.
The vertex of the modulus function is at (- 9, - 5).

Please answer fast, it's important... Q) find the volume of cube whose dimensions are (x+7y), (7x-y) and (xy-5).
Answer:
[tex]Volume = 7x^3y+48x^2y^2-7xy^3 -35x^2-240xy-35y^2[/tex]
Step-by-step explanation:
Given
Shape: Cube
Dimension: (x+7y), (7x-y) and (xy-5).
Required
Determine the volume
The volume is calculated by multiplying the dimensions:
[tex]Volume = (x+7y) * (7x-y) * (xy-5)[/tex]
Evaluate the first 2 brackets
[tex]Volume = [x(7x-y)+7y(7x-y)] * (xy-5)[/tex]
[tex]Volume = [(7x^2-xy)+(49xy-7y^2)] * (xy-5)[/tex]
[tex]Volume = [7x^2-xy+49xy-7y^2] * (xy-5)[/tex]
[tex]Volume = [7x^2+48xy-7y^2] * (xy-5)[/tex]
Open brackets
[tex]Volume = xy[7x^2+48xy-7y^2] -5[7x^2+48xy-7y^2][/tex]
[tex]Volume = 7x^3y+48x^2y^2-7xy^3 -35x^2-240xy-35y^2[/tex]

Jan 10, 7:28:48 PM What is the slope of a line parallel to the line whose equation is 3x - 6y = 18. Fully reduce your answer.
Answer:
[tex]1/2[/tex]
Step-by-step explanation:
We are given the line:
[tex]3x-6y=18[/tex]
And we want to find the slope of the line parallel to this given line.
Remember that parallel lines have the same slope. So, if we can determine the slope of the given line, we have the slope of its parallel line.
To determine the slope of the given line, we simply have to isolate the y. So, we can first divide everything by 3. This yields:
[tex]x-2y=6[/tex]
Adding 2y to both sides yields:
[tex]x=6+2y[/tex]
And subtracting 6 from both sides yields:
[tex]x-6=2y[/tex]
Finally, dividing everything by 2 gives us:
[tex]\displaystyle y=\frac{1}{2}x-3[/tex]
Hence, the slope of our line is 1/2.
So, the slope of the line parallel to this line must also be 1/2.

Answer:
B) Vertically stretched by a factor of 3, shifted to the right by 1 unit, and shifted up 2 units.
Step-by-step explanation:
The basic transformations of a rational function as shown here can be modeled by:
[tex]f(x) = \frac{a}{b(x - h)} + k[/tex]
a = vertical stretch / compression.
b = horizontal stretch / compression.
h = horizontal shift.
k = vertical shift.
If there is a negative sign by a, then it is a vertical reflection.
If there is a negative sign by b, then it is a horizontal reflection.
_____________
As seen here, the transformations of
[tex]f(x) = 2 + \frac{3}{x–1} [/tex]
There is no b value because x - 1 is completely factored or it can just be thought of as 1. a or the vertical stretch is a factor of 3 because that is the numerator of the rational expression. There is a horizontal shift of 1 unit to the right because when x is subtracted by 1 in the rational expression, the root of x - 1 by itself is 1 greater than x. Lastly, there is a vertical shift up 2 units because that means all the values of the function will increase by 2 units which moves the whole function up 2.

>) Jamal can run 1 mile in 5.05 minutes.
If Jamal maintains this pace during
a 5-kilometer (5K) race, he expects
to break the course record of
15.25 minutes. Is Jamal's expectation
reasonable? Explain.
Answer:
Yes, his expectation is reasonable
Step-by-step explanation:
Mathematically;
1 mile = 1.609344 km
If he runs this in 5 minutes;
his speed will be 1.609344/5 = 0.3219 km/m
Now he intends breaking the record of 5 kilometers in 15.25 minutes
Distance = speed * time
What we shall have in this case will be;
15.25 * 0.3219 = 4.908
Approximately this is 5 km
So we can conclude that he will break the record if he runs at this speed
