Find the equation of the line.

Mathematics
1 answer:

Answer:

y = 2/3x - 7

Explanation:

First we must turn 3x + 2y = 6 to slope intercept form. In order to do this first subtract 3x on both sides of the equal sign, so we can get 2y by its self. Now we're left with 2y = -3x + 6 .

Next divide 2 from both sides to get y by its self. Now you got y = -3/2x + 3 (since 6 can be divided by 2 it's a 3 now) <u>Look above to see y= -3/2x +3 graphed</u>. ⤴⤴⤴

To find out the other equation we first need to know what its y-intercept is, and luckily for us we've already been given -3.

<u>Look above to see (6,-3) graphed</u>. ⤴⤴⤴

<u>Look above to see </u><u>both</u><u> </u><u>y = -3/2x + 3 </u><u>and</u><u> </u>

<u>y = 2/3x -7 graphed</u>. ⤴⤴⤴

This is a bit lengthy, but I hope you get it :)

A rectangle has an area of 36 inches squared. Write an equation to show how the length (l) varies inversely the width (w).
Anastaziya [24]
Start with the first sentence, and the definition of the area of a rectangle:
l * w = 36

Rewrite the equation to get
l = 36 / w
or
w = 36 / l
Either one shows the inverse relationship between w and l.

Assuming the last part wants you to write an equation for an x-y graph, the equation would be
y = 36 / x

An artist wants to frame a square painting with an area of 400 square inches. She wants to know the length of the wood trim that
marysya [2.9K]
Area of square painting is 400 square inches.

Let the side of square painting is = a inch

So the area of square painting is = a^2 square inch.

So a^2 = 400&#10;&#10;a =  \sqrt{400}

a = 20 inch

Length of wood trim to need to go around the painting is equal to the perimeter of square painting .

So the perimeter of square painting is = 4 * (side)
                                                                  = 4* 20 = 80 inch.

So the required length of wood trim is = 80 inch.

Ishaan is 2 times as old as Christopher. 35 years ago, Ishaan was 7 times as old as Christopher. How old is Ishaan now?
MrRissso [65]
I= Ishaan's age= 2C
C= Christopher's age

35 years ago means we have to subtract 35 from their current age. Ishaan minus 35 equals 7 times Christopher minus 35 years.

CHRISTOPHER'S AGE:
I - 35= 7(C-35)
substitute I=2C in for I
multiply 7 by all in parenthesis

2C - 35= 7C - 245

add 35 to both sides
2C= 7C - 210

subtract 7C from both sides
-5C = -210

divide both sides by -5

C= 42 Christopher's age


ISHAAN'S AGE:
I= 2C
substitute C=42 to find Ishaan's age
I= 2(42)

I= 84 Ishaan's age

CHECK:
Substitute answers in original equation

I - 35= 7(C-35)
84 - 35= 7(42-35)
49= (7*42)+(7*-35)
49= 294-245
49=49

Hope this helps! :)
