Write an equation parallel to the given line through the given line through the given point.

1 answer:

6 0

The format of a line equation is y = mx + b
When two lines are parallel, their 'm' variables are equal.
Knowing this, the unknown line equation, so far, would look like this:
y = 9x + b
Since we know that the line equation goes through the point (2, 7)
7 = 18 + b
b = -11
y = 9x - 11

I count five 'k's there, so that part of the expression is

k⁵ .

Two 'n's form the rest of it, so that part is n² .

The parts are multiplied, so the simplest form of the expression is

When 2/3 is added to a certain number, the sum is 3 greater than twice the number. part 1: set up an equation using n to represe

Gennadij [26K]

2/3 + n = 2n + 3 <== ur equation
2/3 - 3 = 2n - n
2/3 - 9/3 = n
-7/3 = n <== ur solution

or
2/3 + n = 2n + 3...multiply everything by common denominator of 3
2 + 3n = 6n + 9
2 - 9 = 6n - 3n
-7 = 3n
-7/3 = n

If a starting number is 30 and it falls to 11 what % decrease is that?

jonny [76]

Answer:

The question would've given you to what number you should round up your answer.

Answer is:

Whole number:

63%

1 decimal place:

63.3%

2 decimal places:

63.33%

Exact number:

$\frac{190}{3}$ %

Step-by-step explanation:

So the starting no. = 30

Ending no. = 11

In order to evaluate the percentage of decrease we:

(Ending number/starting number) * 100

So:

$\frac{11}{30} *100 = \frac{11}{3} *10 = \frac{110}{3}%$ %

To find the Decrease percentage:

100 % - 110/3 %

= 63.333%
