Answer:

y=-3x-5

Step-by-step explanation:

given equation:

3y=x-4

slope intercept form is y=mx+b

(m is the slope, b is the y intercept)

divide by 3

y=1/3x-4/3

perpendicular lines have slopes that are negative and reciprocal. If you multiply them together, the result is -1.

so to find the slope of the perpendicular line, use this equation:

1/3m=-1

multiply by 3

m=-3

the slope of the new line is -3.

here is our equation so far:

y=-3x+b

now, we need to find b.

Since the equation of the line passes through the point (-2,1) we can substitute that into the equation to find b

1=-3(-2)+b

multiply

1=6+b

subtract 6

-5=b

so the line is y=-3x-5

Hope this helps!

the answer is 28

Answer:

4/7

Step-by-step explanation:

The amount of cup of chocolate each person get is 4/7.

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

Number of person = 7

Number of cups of chocolate = 4

The equal amount of hot chocolate each person gets.

= 4/7

Thus,

4/7 cup of hot chocolate each person got.

Step-by-step explanation:

The picture shows us that the shape is a square.

To find the area of a square you would use the formula s^2

s= 8ft

8ft^2 = 64ft^2

with area you would need to use the unit ft^2

I hope this helps!!!

Answer: DDDDDDD

Step-by-step explanation: The formula is width x height, so we can use the expression 8 x 8 assuming this is perfectly square. 8 x 8 is 64 square units

Answer:8/9 n- 12/9

Step-by-step explanation: You do distributive property.Which is 4/9 times 2 n  but you make  both 4/9 and 2 to a fraction which is 4/9 times 2/1 which gives you 8/9 .Next you do 4/9 times 3  but make to a fraction both which is 4/9 times 3/1 which gives you 12/9 .Next you take the 8/9 n and 12/9 and you subtract it .Which gives you 8/9 n- 12/9  as your expression.

Answer:

We get Y=4 when X =24

Step-by-step explanation:

If Y varies directly with X,  find Y when X=24, if Y = 5  when X= 30.​

We are given If Y varies directly with X, we can write:

[tex]Y\:\alpha\: X\\Y=kX[/tex]

Where k is constant of proportionality

We need to find Y when X=24, first we need to find k, the constant of proportionality.

Now, we are given: If Y = 5  when X= 30.​

We can find value of k

[tex]Y=kX\\5=k(30)\\k=\frac{5}{30}\\k=\frac{1}{6}[/tex]

So, k=1/6

Now, we will find Y when X = 24

and k=1/6

[tex]Y=kX\\Y=\frac{1}{6}(24)\\Y=4[/tex]

So, Y=4 when X =24.

Answer:

5.3

Step-by-step explanation:

It will take a time 0f 5.5 hours to pick 40 bushels of apple if they worked together.

Proportions are defined as the concept where two or more ratios are set to be equal to each other.

Suppose we have two ratio p : q and r : s.

If both these ratios are proportional, then we can write it as p: q : : r : s.

This is same as p : q = r : s or p/q = r/s

Given that,

Amount of bushels picked by Maria in 10 hours = 40

Amount of bushels picked by Maria in 1 hour = 40/10 = 4

Amount of bushels picked by Kayla in 12 hours = 40

Amount of bushels picked by Maria in 1 hour = 40/12 = 3.333

Amount of apple picked by both Maria and Kayla in 1 hour if they worked together = 4 + 3.333 = 7.333

Let x be the time taken to pick 40 bushels of apple by both.

Using proportional concept,

x / 40 = 1 / 7.333

x = 40 / 7.333

x = 5.4548 ≈ 5.5 hours

Time taken if they both worked together is 5.5 hours.

Answer:[tex]-\frac{189}{208}[/tex]

Step-by-step explanation:

Given

[tex]\sin x=\frac{8}{10}[/tex]

x lies in the second quadrant where sin and cosec is positive and rest trigonometric functions are negative

so, [tex]\cos x=-\sqrt{1-sin ^2 x}\\\cos x=-\sqrt{1-(\frac{8}{10})^2}=-\sqrt{\frac{36}{100}}\\\cos x=-\sqrt{\frac{6}{10}}[/tex]

[tex]\tan x=\frac{\sin x}{\cos x}=-\frac{4}{3}[/tex]

similarly, [tex]\tan y=-\frac{12}{5}[/tex]

Also, y lies in 4 th Quadrant where cos and sec is positive and rest trigonometric functions are negative

[tex]\sec y=\sqrt{1+\tan ^2y}=\sqrt{1+(-\frac{12}{5})^2}\\\sec y=\frac{13}{5}\\\cos y=\frac{5}{13}\\\sin y =\frac{\tan y}{\cos y}=-\frac{12}{13}[/tex]

Now putting the values

=[tex]\dfrac{\cos x \cos y+\sin x\sin y}{\tan x-\tan y}=\dfrac{(\frac{-6}{10})(\frac{5}{13})+(\frac{8}{10})(\frac{-12}{13})}{(\frac{-8}{6})-(\frac{-12}{5})}\\\dfrac{\cos x \cos y+\sin x\sin y}{\tan x-\tan y}=\dfrac{\frac{-126}{130}}{\frac{16}{15}}=-\frac{189}{208}[/tex]
