Which describes a line parallel to the line described by y = –3x + 2?
O y = -3x
O y = (1/3)
O y = 2 - 3x
O y = (1/3)x + 2
Answer:
(1/3x) + 2
Step-by-step explanation:
you need to do the opposite reciprocal of -3x
the opposite sign of - is + so it is positive
the reciprocal of 3 is 1/3

a bank of 16 floodlights together 4000 watts of power. how much power is used by each bulb?
Answer:
250 watts
Step-by-step explanation:
If 16 floodlights together use 4000 watts of power, each floodlight uses 250 watts.
1. 16 floodlights use 4000 watts together
2. 4000÷16=250
3. 250 watts used by each floodlight
The answer might be incorrect, as power may not be straight forward to calculate with division, but hopefully the explanation helps!

The least common denominator of the two rational terms is
Answer:
2 And 9Step-by-step explanation:
The Least Common denominator of two reational terms is 2 and 9The LCD of 2 and 9 is 18Line a is parallel to line b. If the measure of <7 is 114 what is the measure of <4?
Using opposite by the same vertex and supplementary angles, it is found that the measure of angle 4 is of 66º.
What are opposite by the same vertex and supplementary angles?When two parallel lines are cut by a transversal, angles that are opposite in a vertex are congruent, that is, they have the same measure.When two angles are supplementary, the sum of their measures is of 180º.In this problem, angles 5 and 7 are opposite by the same vertex, hence:
m<7 = m<5 = 114º.
Angles 4 and 5 are supplementary, hence:
m<4 + m<5 = 180º.
m<4 = 66º.
The measure of angle 4 is of 66º.

Step-by-step explanation:
Which of the following functions will represent $500 placed
into a mutual fund yielding 10% per year for 4 years.
• A = 500(.10)^4
• A = 500(1.1)^4
• A = 500(4)(.10)
• A = 500(1.04)^10
Answer:
the answer is the first one
Step-by-step explanation:
The functions will represent $500 placed into a mutual fund yielding 10% per year for 4 years is A = 500(1.1)^4
what is Compound Interest?In order to compute compound interest, multiply the principle of the original loan by the annual interest rate multiplied by the number of compound periods minus one. You will then be left with the principal amount of the loan plus compound interest.
given:
P= $500
First, convert R as a percent to r as a decimal
r = R/100
r = 10/100
r = 0.1 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 500.00[tex](1 + 0.1/1)(1)^4[/tex]
A = 500.00[tex](1.1)^4[/tex]
A = $732.05
Hence, the functions will represent $500 placed into a mutual fund yielding 10% per year for 4 years is A = 500(1.1)^4

Which statements about the system are true? Check all that apply.
y= -13x - 4
3y-x= -7
a
Both lines have the same y–intercept.
b
The system consists of parallel lines.
c
The equations represent the same line.
d
The system has one solution.
e
Both lines have the same slope.
Answer: D
Step-by-step explanation:
To compare the two lines, we want to a=make sure that they are in the same form.
3y-x=-7 [add both sides by x]
3y=x-7 [divide both sides by 3]
y=1/3x-7
Now that the equations are in the same form, we can compare them.
In order for the equations to have the same y-intercept, the "b" must be the same. The y-intercept for the first equation is -4, while the y-intercept for the second equation is -7. Therefore, A is not the answer.
If the lines are parallel, they must have the same slope. Parallel lines NEVER touch or cross, hence the slope has to be the same. The slope for the first equation is -13, while the slope for the second equation is 1/3. Therefore, B is not the answer.
We know that E is not the answer because the paragraph above proved that the slope are not equal.
We also know that the equations do not represent the same line. If they are the same line, the equations would be identical.
We know that D is the correct answer. A system of linear equaitons can only have ONE solution. We set the equations equal to each other to find the solution. The intersection point is the solution.
Therefore, we know that D is the right answer.

Find the slope of the line that passes through (2, 6) and (-7, 8)
Answer:
-2/9
Step-by-step explanation:
The slope of the line passing through the given points is [tex]\frac{2}{-9}[/tex]
What is slope?The slope or gradient of a line is a number that describes both the direction and the steepness of the line.
Given are two points (2, 6) and (-7, 8) from which a line passes. We need to find the slope of the line.
We know that, the slope of a line passing through points (x₁, y₁) and (x₂, y₂) = (y₂-y₁) / (x₂-x₁)
In the given points, y₂ = 8, y₁ = 6, x₂ = -7 and x₁ = 2
Therefore, the slope of line = 8-6 / -7-2 = [tex]\frac{2}{-9}[/tex]
Hence, the slope of the line passing through the given points is [tex]\frac{2}{-9}[/tex]

Answer:
20
Step-by-step explanation
use the formula a²+b²=c²
since a=21 and c=29 you need to solve for b
Put 21 in for a and 29 in for c
21²+b²=29²
21²=441
29²=841
so then the equation would be 441+b²=841
subtract both sides by 441
then you have b²=400
now just find the square root of 400
√b²=√400
b=20

how do I do this question?
Answer:
Choice C
Step-by-step explanation:
We are given the function:
[tex]\displaystyle \large{f(x)=3x+5}[/tex]
Let [tex]\displaystyle \large{y=f(x)}[/tex] therefore:
[tex]\displaystyle \large{y=3x+5}[/tex]
To find an inverse of function, swap the position of x and y:
[tex]\displaystyle \large{x=3y+5}[/tex]
Then solve or simplify the equation in term of y:
[tex]\displaystyle \large{x-5=3y}\\\displaystyle \large{\frac{x-5}{3}=y}\\\displaystyle \large{y=\frac{1}{3}x-\frac{5}{3}}[/tex]
Therefore, the answer is choice C.
__________________________________________________________
Summary
An inverse function is a function that swaps the position of domain and range, defined as notation [tex]\displaystyle \large{f^{-1}(x)}[/tex] or [tex]\displaystyle \large{y^{-1}}[/tex] generally. When finding an inverse function, make sure to swap position of range and domain, if given the interval.
Only one-to-one functions may have an inverse — multiple-to-one can not have an inverse such as quadratic function or any even-degree polynomial functions.

Step-by-step explanation:
Use the SOH-CAH-TOA method.
We are given an angle (37°).
We know a side that is opposite of the angle.And we are trying to find the hypotenuse.
So we use SOH
[tex] \sin(x) = \frac{o}{h} [/tex]
[tex] \sin(37) = \frac{0.6}{h} [/tex]
Isolate h
[tex]h = \frac{0.6}{ \sin(37) } [/tex]
Which gives us 1.
So the answer is 1.
The length and width of a rectangle are in the ratio 3:4. The perimeter of the rectangle is 84 cm. Find the length and width of the rectangle.
The length of the rectangle is 18 cm, and the width is 24 cm as per the concept of perimeter.
Let the length of the rectangle be 3x and the width be 4x, where x is a common factor.
The perimeter of a rectangle is given by the formula:
Perimeter = 2 × (Length + Width)
Given that the perimeter is 84 cm, we can write the equation as:
84 = 2 × (3x + 4x)
Now, let's solve for x:
84 = 2 × 7x
42 = 7x
x = 42 / 7
x = 6
Now that we have the value of x, we can find the length and width of the rectangle:
Length = 3x = 3 × 6
= 18 cm
Width = 4x = 4 × 6
= 24 cm
Therefore, the length of the rectangle is 18 cm, and the width is 24 cm. The length and width are in the ratio 3:4, and the perimeter of the rectangle is indeed 84 cm.
