Which of the following lines is perpendicular to the equation given below?
y=−2x+8
A. 2x−y=12
B.x−2y=6x
C.x+2y=8x
D.2x+y=4
Answer:
B. x−2y=6Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes
The given line is
y = -2x + 8Perpendicular line to this must have a slope of
- 1/(-2) = 1/2Option A
2x - y = 12y = 2x - 12Slope is 2NoOption B
x - 2y = 62y = x - 6y = 1/2x - 3Slope is 1/2YesOption C
x + 2y = 82y = - x + 8y = -1/2x + 4Slope is -1/2NoOption D
2x + y = 4y = -2x + 4Slope is -2NoAnswer:
B. x−2y=6
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes
The given line is
y = -2x + 8
Perpendicular line to this must have a slope of
- 1/(-2) = 1/2
Option A
2x - y = 12
y = 2x - 12
Slope is 2
No
Option B
x - 2y = 6
2y = x - 6
y = 1/2x - 3
Slope is 1/2
Yes
Option (C) is correct
x + 2y = 8
2y = - x + 8
y = -1/2x + 4
Slope is -1/2
No
Option D
2x + y = 4
y = -2x + 4
Slope is -2
No

Find the Inverse
Answer:
Step-by-step explanation:
Ok
Step-by-step explanation:
when trying to find the inverse of a function just replace x with y and try to make the y the subject of the formula.
x = 1/2(y) + 1
x+1 = 1/2 (y)
2(x+1) = y

Which linear equation has a slope of 3 and a y-intercept of -2
y=3x +2
y=3x - 2
y=-2x + 3
y=2x - 3
Answer:
y=3x‒2
Step-by-step explanation:
y=3x‒2 in this equation slope is 3 cause slope is the number that is a coefficient of x.
&also the y-intercept of the equation is ‒2. y=3(0)‒2
y=0‒2=‒2
cause to find y-intercept is to substite 0 instead of x &to solve

Tell weather it is possible to draw a triangle with the given side lengths
a. 3 in, 4 in, 5 in.
b. 1 cm, 7cm, 8cm
c. 3ft, 5ft, 9ft
Answer:
The set of numbers 3 in, 4 in, and 5 in can form a triangle. a) is correct
Explanation:
A triangle is possible to be drawn only if the sum of the lengths of any two sides is greater than the length of the third side.
a) Is correct.
Testing all the posible combinations: 3+4>5, 4+5>3, 3+5>4. True. Hence, Option a is the correct choice,
b) Is incorrect
Since 1+7>8 is false, this choice is not correct
c) Is incorrect
Since 3+5>9 is false, this choice is not correct

His unit rate is mile(s) per hour.
Answer:
Slope = ⅘
Unit rate = 0.8 mile per hour
Step-by-step explanation:
The slope of the graph is simply the constant rate of change along the line of the graph or change in y-coordinates of two points divided by change in their corresponding x-coordinate.
For the graph given, distance (miles) is the y-variable, while time (hours) is the x-variable.
Given that Jorge travels 4 miles for every 5 hours, therefore, the slope of the graph plotted can be represented as [tex] \frac{4}{5} [/tex]
The unit rate would be 4:5 = ⅘ = 0.8 mile per hour.

Melinda made a scale model of an airplane. In the scale model, the length of the wingspan is 8 inches. The length of the wingspan of the actual airplane is 56 feet in length. Which scale did melinda usr to create the scale model of the airplane?
Answer: 1 inch =7 feet
Step-by-step explanation:
Scale factor = [tex]\dfrac{Image \ size}{original \ size}[/tex]
The length of the wingspan in model is 8 inches.
The length of the wingspan of the actual airplane is 56 feet in length.
Scale factor = [tex]\dfrac{56}{8}=7\text{ feet per inch}[/tex]
i.e. 1 inch of model gives 7 actual feet.
Required Scale: 1 inch=7 feet

Step-by-step explanation:
Not sure what you mean by "solve" as this is an expression, anyhow..
Our common monomial factor is [tex]3x^{2}[/tex]
By factoring out this monomial, we get [tex](x-1)[/tex]
To prove this is the answer, we can do [tex]3x^2(x-1)[/tex] and see that they multiply to the original expression.

Which graph represents the inequality x > 3?
Answer:
I think the answer is C
Step-by-step explanation:
Since the > symbol doesn't have the line under it, it is a dash line, considering its not equal to. It's also suggesting that x is more than 3 so it goes to the right
the school cafeteria is offering a choice of two side dishes at lunch today either watermelon or french fries the ratio of the number of orders of french fries to the total number of side dishes ordered is 9:14
A: there are 9 orders of french fries for every 14 orders of watermelon
B:there are 5 orders of watermelon for every 9 orders of french fries
C: there are 14 orders of french fries for every 9 orders of watermelon
D: there are 5 orders of french fries for every 9 orders of watermelon
Answer:
B
Step-by-step explanation:
Here, we are to select the best option that defines the ratio given in the question;
From the question, we are told that the ratio of french fries to the number of side dishes ordered is 9:14
Since 9 represents the french fries, then the ratio representing water melon orders will be 14-9 = 5
Hence, the ratio of french fries orders to water melon orders will be 9:5
The correct option is thus;
There are 9 orders of french fries for every 5 orders of watermelon
Or
There are 5 orders of watermelon for every 9 orders of french fries

The art room at a school is made up of 3 sections which are a pottery section a painting section and a sculpture section. Art work will be on display for an art show in all sections of the art room except the sculpture section, how much space is available for the art section ?
Answer:
2/3 or 66.6%
Step-by-step explanation:
Based on the information provided we see that there are a total of 3 sections that make up the entirety of the art room. Since the artwork will only be displayed on 2 sections out of the 3 that are available then there is 2/3 of the total amount of space available for the art section. In other words, only 66.6% of the art room is available for the art to be displayed on, while 33.3% is currently occupied and unavailable.
5-4x=6+2x I need help right now SOMEBODY ANSWER STEP BY STEP PLZ HELP
Answer:
-1/6
Step-by-step explanation:
5-4x=6+2x
Add 4x to each side
5-4x+4x=6+2x+4x
5 = 6+6x
Subtract 6x from each side
5-6 = 6+6x-6
-1 = 6x
Divide by 6
-1/6 = 6x/6
-1/6 =x

What is the distance between points D and F?
A. 5.4
B. 4.2
C. 3.7
D. 2.6
Answer:
ans is A.............
The required distance between points D and F is 5.4 units.
Coordinate, is represented as the values on the x-axis and y-axis of the graph
Here,
The coordinate of point D is (2, 0) and the coordinate of point F is (-3, -2).
The distance between points D and F can be evaluated by the distance formula,
[tex]DF = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]
Substitute the value in the above equation,
[tex]DF = \sqrt{(2 + 3)^2 + (0 + 2)^2}\\ DF = \sqrt{25 + 4}\\ DF = \sqrt{29}\\ DF = 5.4[/tex]
Thus, the required distance between points D and F is 5.4 units.
