Find the equation of the line that is parallel to the given line and passes through (9,1) y=2/3x -2

Nadya [2.5K]

When the lines are parallel, the slopes of these lines are equal.
For a new line,
y = (2/3)x + b.

To find b, we need substitute x and y with values of the point (9,1).
x=9
y=1

1 = (2/3)*9 + b
1 = 6 + b
b=-5

The equation of the line is y = (2/3)x - 5.

Find f(-3), f(-1), and f(1)

suter [353]

Answer:

I will just show you how to substitute.

Step-by-step explanation:

all you have to do is just plug f(x) into the number you want. So if you see any x's, all you gotta do is plug that number after f for x.

So an example of an equation for one of your number is:

$f\left(x\right)=x^2+x$

you then want to plug the number after f for the x's. (I'm doing f(-3).

$f\left(-3\right)=\left(-3\right)^2-3$

You then should get the equation above.

after that you solve.

$f\left(-3\right)=9-3$

$f\left(-3\right)=6$

just follow these steps and you should be fine :))

What is the HCF of two consecutive numbers?

Luba_88 [7]

Answer: The HCF o two consecutive numbers is always one.

Step-by-step explanation: The reason behind this is that the two consecutive numbers do not have any common factor other than 1. Hence 1 becomes the highest common factor between two consecutive numbers
