Answer:
y = -1x - 2/2
Step-by-step explanation:
Slope is -1
B = 2/-2
Answer:
y = x - 4
Step-by-Step Explanation:
Perpendicular lines have slopes that are negative reciprocals—multiplying their slopes result in -1.
Given the slope of a line m = -1, then it means that the slope of the other line must be 1 (because multiplying the slope of line 1 (m1 = -1), and the slope of the other line (m2 = 1) results in: -1 × 1 = -1).
Therefore, given the slope of line 2 (m2 = 1), and the point (2, -2), we could plug these values into the slope-intercept form and solve for the y-intercept (b):
y = mx + b
-2 = 1(2) + b
-2 = 2 + b
Subtract 2 from both sides to solve for b:
-2 - 2 = 2 - 2 + b
-4 = b
Therefore, the y-intercept (b) = -4.
Hence, the equation of the perpendicular line is: y = x - 4

Answer:
A
Step-by-step explanation:
just did it :)
The statement that best describes how ultrasound can produce an image is sound waves that form outside the body reflect off the body and are detected by the machine.
What is Ultrasound?Diagnostic ultrasound, also called sonography or diagnostic medical sonography, is an imaging method that uses sound waves to produce images of structures within your body.
We have some statements that describes how ultrasound can produce an image.
The ultrasound image is produced based on the reflection of the waves off of the body structures. The strength (amplitude) of the sound signal and the time it takes for the wave to travel through the body to provide the information necessary to produce an image.
Therefore, the statement that best describes how ultrasound can produce an image is sound waves that form outside the body reflect off the body and are detected by the machine.

let us suppose breadth of the room be x.
then, length = 2x
now ,the cost of plastering the floor is RS 1080 at rate of RS 15 per ...
hence
the area of floor{length *breadth} =1080/15
x*2x=72
or,2x^2=72
or,x=√(72/2)
hence, the value of x= 6m
(ie. breadth {x}=6. &. length {2x}=12)
again....
we have ,
volume of the room (length *breadth*height)is 396m^3
12*6*height=396
72*height=396
height=396/72
hence , height=5.5
we know,
the area of 4 walls = 2( length+breadth)*height
=2(12+6)*5.5
=198
hence the cost of plastering 4 walls at the rate of RS 20 per SQ meter = 198*20=RS 3960

A man uses 2/5of his piece of land to keep poultry,1/4 for bulls, 1/7 of the remainder for goats and test for sheep.If he uses 12 acres for goats, determine the total acreage he uses for sheep. (3marks)
Answers
Answer:
72
Step-by-step explanation:
We will first have to find the fraction of the whole land goats use. If we add 2/5 and 1/4, we will get 13/20. Simplifying the expression 1-13/20 gets 7/20, which is the total fraction of land the goat and sheep has. The goat will then get 7/20*1/7 of the whole land, which is 1/20. The sheep will then get 7/20*6/7 of the entire land, which is 3/10. Because 1/20 of the whole land is 12 acres, the farmer has 240 acres. SImplifying the expression 240*3/10 gets 72 acres
Write the slope-intercept form of the equation to the line parallel to the graph
of y+6=-4(x-1) that passes through the point (2,4).
Answers
Answer:
y = -4x + 12
Step-by-step explanation:
Parallel lines have the same slope. Since the slope of the given equation is -4, then the slope of the other line parallel to it must be the same.
Using the slope, m = -4, and the given point, (2, 4):
Substitute these values into the slope-intercept form:
y = mx + b
4 = -4(2) + b
4 = -8 + b
4 + 8 = -8 + 8 + b
12 = b
Therefore, the equation of the line parallel to y + 6 = -4(x - 1) is:
y = -4x + 12
Answer:
4x-2
Step-by-step explanation:
Slope intercept form is y=mx+b, so get y on one side.
do the multiplication first -4(x-1) is -4x+4
Now move the six to the other side; y=-4x+4-6
Simplify, y=-4x-2

In the given equation, y = 1/3x, where it represents a proportional relationship:
1/3 represents the constant of proportionality which shows that as x increases, y also increases at the same rate. The constant of proportionality in this given instance is also the rate of change, or the slope.
The constant of proportionality under the direct proportion condition is the slope of the line when plotted for two proportional constants x and y on a graph.

Challenge A movie theater sends out a coupon for 15% off the price of a ticket. Write an equation
for the situation, where y is the price of the ticket with the coupon, and x is the original price of the
ticket. Use pencil and paper. Draw a graph of the equation and explain why the line should only be
in the first quadrant
Answers
Answer:
The equation is y= 0,65 x
If x is the price of the ticket without the coupon, and the theater offers a discount if you have a coupon, then having a coupon means that the price a person ultimately pays (y) is the original price (x) minus a 35% of this price: y= x -0.35 x . By association: y= (1-0.35) x and then y= 0.65 x.
The line should be in the first quadrant because the first quadrant allows you to represent a situation in which the dependent variable (y) and the independent variable (x) are both positive. This is the case in this exercise, because both prices, the one without discount (x) and the one with discount (y) are necessary positive (you can not pay a negative price!).
Step-by-step explanation:
The price without discount (or without the coupon) is x.
The price with discount (or with coupon) is y.
y and x are both related: y is a percentage of x, specifically, y is 35% smaller than x. This means that y =0.65 x.
Answer:
0.85x

The regular price of a t-shirt is 18 dollars. What price will you pay after a 20% discount
Answers
Answer: $14.40
Step-by-step explanation:
Full price = $18.00
20% discount of full price = $18.00 x [tex]\frac{20}{100}[/tex]
= $18.00 x 0.2

Price paid after 20% discount = full price minus 20% discount

15. One of two complementary angles is 18 less than the other.
Find the measure of each angle.
Answers
Answer: 36° and 54°
Step-by-step explanation:
Let the larger angle be 'R' and the smaller angle 'q'
⇒ R + q = 90 [since complementary angles have a sum of 90°]
Then R - q = 18 [since 1 of 2 complementary angles is 18 less than other]
We can combine the equation
(18 + q) + q = 90
18 + 2q = 90
2q = 72
q = 36
We can solve for R
R - 36 = 18
q = 36 + 18
q = 54

Pls Hurry: Ruben bought 2 candy bars and 4 bags of chips for $24. Lucia bought 2 candy bars and 2 bags of chips for $14. What was the cost of the individual candy bar and a bag of chips?
Answers
Answer:
A candy bar costs $0.80
A bag of chips costs $6.20
Step-by-step explanation:
Let's call candy bars x, and bags of chips y.
Ruben ought 2x and 4y for $24
Lucis bought 2x and 2y for $14
This means that 2x+4y = 24 and 2x+2y = 14
Now we have a system of equations that we can solve.
2x + 2y = 14
2(x + y) = 14
x + y = 7
y = 7 - x
Plug this into the next equation to get:
2x + 4y = 24
2x + 4(7 - x) = 24
2x + 28 - 7x = 24
28 - 5x = 24
-5x = -4
x = -4/-5
x = 4/5 = 0.8
plug that x value into y = 7 - x to find y
y = 7 - x
y = 7 - (4/5)
y = 245/35 - 28/35
y = 217/35 = 6.2
now we can check our work:
2(x + y) = 14
2(6.2 + 0.8) = 14
2(7) = 14
14 = 14
^ this means our values are correct
Answer:
A candy bar costs $0.80
A bag of chips costs $6.20
