What is perpendicular to y= 3x -9 and passes through the point (3,1)

Answers

Answer 1

Answer: $(3,1) , \ \ y= 3x -9 \n \n The \ slope \ is :m _(1) =3 \n \n If \ m_(1) \ and \ m _(2) \ are \ the \ gradients \ of \ two \ perpendicular \n \n lines \ we \ have \ m _(1) \cdot m _(2) = -1 \n \n3\cdot m_(2)=-1 \ \ /:3\n \n m_(2)=-(1)/(3)$

$\Now \ your \ equation \ of \ line \ passing \ through \ (3,1) would \ be: \n \n y=m_(2)x+b \n \n1=-(1)/( 3) \cdot3 + b$

$1=-1+b\n \n b=1+1\n \nb=2 \n \n y =- (1)/(3)x+2$

Option C is the correct answer.

Step-by-step explanation:

We need to find 25 x = 65

Dividing both sides by 25

We will get

$25x=65\n\n(25x)/(25)=(65)/(25)\n\nx=(13* 5)/(5* 5)\n\nx=(13)/(5)\n\nx=2.6\n\nx\approx 3$

Option C is the correct answer.

The calculated value of x in the equation 2/5x = 6/5 is (c) 3

How to calculate the value of x in the equation

From the question, we have the following parameters that can be used in our computation:

2/5x = 6/5

Divide through the equation by 2/5

So, we have the following representation

(2x/5)/(2/5) = (6/5)/(2/5)

Evaluate the quotient on the right hand side

(2x/5)/(2/5) = 3

Lastly, we have

x = 3

Hence, the value of x in the equtaion is x = 3

Answer: After washing 20 cars together, each team will have raised the same amount in total.

Step-by-step explanation:

Let x represent the number of cars that each each teams will wash for them to raise the same amount in total.

The volleyball team gets $4 per car. In addition, they have already brought in $24 from past fundraisers. This means that the total amount raised by the volleyball team after washing x cars would be

4x + 24

The wrestling team has raised $84 in the past, and they are making $1 per car today. This means that the total amount raised by the wrestling team after washing x cars would be

x + 84

For both amounts to be equal, the number of cars would be

4x + 24 = x + 84

4x - x = 84 - 24

3x = 60

x = 60/3

x = 20

On a coordinate plane, polygon GHIJ translates 8 units to the left to form polygon G'H'I'J'. Which of the following equations is not necessarily true?

Answers

When you translate a figure, none of the lengths change and none of the angles change. The only equation you listed that does not equate two translated lengths or two translated angles is G'H' = 8 units. There is nothing in the statement of the problem that requires this to be true.

Answer:

It's D: m∠HI'J = m∠H'IJ'
