I need help with this problem so i got 12 but the correct answer is 18. What is the value of |x|+y when x is -3 and y is 15. please show how you got 18

Answers

Answer 1

Answer: remember |(._.)|=positive (._.)

evaluate seperately
when x=-3
|-3|=3
when y=15
so therefor
|-3|+15=
3+15=18

Equation through (-1,4) and perpendicular to 3y=2x-1

Answers

Answer:

The equation of line perpendicular to given line and passes through points ( - 1 , 4 ) is 2y = -3x + 5

Step-by-step explanation:

Given line equation as :

3 y = 2 x - 1

Or, y = $(2)/(3)$ x - $(1)/(3)$

So , The equation is in the form of y = m x + c

Where m is the slope of the line

∴ satisfying the condition

Slope of given line is m = $(2)/(3)$

Now , ∵ The other line is perpendicular to this line and passes through point ( - 1 , 4 )

Let , Slope of other line = M

∴ for perpendicular line condition , products of the slope = - 1

I.e m × M = - 1

Or , M = - $(1)/(m)$

Or M = - $(1)/((2)/(3))$

Or M = - $(3)/(2)$

Thus The equation of line with slope M and passing through points ( - 1 , 4 ) is

$y-y_1 = M (x-x_1)$

or, $y-4 = - [tex](3)/(2)$ (x + 1)[/tex]

or, 2y - 8 = - 3 (x +1)

Or, 2y - 8 = - 3x - 3

or 2y = - 3x - 3 + 8

∴ 2y = -3x + 5

Hence The equation of line perpendicular to given line and passes through points ( - 1 , 4 ) is 2y = -3x + 5 Answer

How do you find the percent of a number greater than 100?

Answers

Answer:

Multiply the number by the percent (e.g. 87 * 68 = 5916)

Divide the answer by 100 (Move decimal point two places to the left) (e.g. 5916/100 = 59.16)

Round to the desired precision (e.g. 59.16 rounded to the nearest whole number = 59)

Step-by-step explanation:

lets say for example 234

234/2 = 117 and the percentage were looking for is ummmm 25% well 25% is 1/4th of 234 making it 1/2 of 117 25% of 234 is 58.8 lets do a harder one what is 47% of 234 Divide n by 100.

Multiply the result by x. making it 109.98

Answer:

To find any percentage all you need to do is take the amount you are looking at divided by the total amount. Than multiply the number by 100.
