Write the equation of the line perpendicular to 3x+y=-8 that passes through (-3,1) . Write your answer in slope-intercept form.

Answers

Answer 1

Answer: I hope this helps you

Answer 2

Answer: The perpendicular vector of 3x + y = -8 would be [3, 1]. Thus, you know that the slope would be 1/3 (the vector is in the form of [x, y]).

Use point-slope form with the perpendicular slope and the point (-3, 1):
$y - y_1 = m(x-x_1)$
$y - 1 = (1)/(3)(x + 3)$

You can simplify this if you want to (maybe to make it look a bit more "cleaner") and either put it as standard form or slope-intercept form.

Answer:

m = -3

Step-by-step explanation:

Slope Formula: $m = (y2-y1)/(x2-x1)$

Simply plug in our coordinates to find slope:

m = (11 - 2)/(5 - 8)

m = 9/-3

m = -3

i believe it’s 23/20

Answer:

$1.15=(23)/(20)$

Step-by-step explanation:

$1.15=(1.15)/(1)=(11.5)/(10)=(115)/(100)=((23)(5))/((2)(2)(5)(5))=(23)/((2)(2)(5))=(23)/(20)$

60% of what number is 72?

Answers

$60%=0.6$

$0.6*x=72$

$0.6x=72$

$x= (72)/(0.6)$

$x=120$

72 is 60% of 120

60 percent of 120 is equal to 72.

We have,

To find the number that corresponds to 60% of a given value, we can set up an equation and solve for the unknown number.

Let's represent the unknown number as "x."

The problem states that 60% (or 0.6 as a decimal) of that number is equal to 72.

0.6x = 72

To isolate "x," we divide both sides of the equation by 0.6:

x = 72 / 0.6

Performing the division:

x = 120

Therefore,

60% of 120 is equal to 72.
