Write a slope incercept equation passes through (-3, 2) and (-2, -1)

Answers

Answer 1

Answer:

Answer:

y = - 3x - 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 3, 2) and (x₂, y₂ ) = (- 2, - 1)

m = $(-1-2)/(-2+3)$ = $(-3)/(1)$ = - 3, thus

y = - 3x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 2, - 1), then

- 1 = 6 + c ⇒ c = - 1 - 6 = - 7

y = - 3x - 7 ← equation in slope- intercept form

How can 3/12 be written in simplest form

Answers

$(3)/(12)$

Find a common factor 3 and 12 in order to cancel it out:

$3=3*1$

$12 = 3*4$

Greatest common divisor of 3,12 is 3

Factor out 3 from the numerator and the denominator:

$(3)/(12) : (3)/(3) = (1)/(4)$

hope this helps!

Hi there! 3/12 can be simplified to1/4. How? Because you make a common denominator (3) and 3 divided by 3 is 1, and 12 divided by 3 is 4 so, it's 1/4!d Hope it helps!

How to write 4/50 as a decimal

Answers

4/50 as a decimal is 0.08

4/50 as a decimal is 0.08
You get this by dividing 4 and 50 or since 50 goes into 100 you multiply numerator and denominator by 2
8/100 which equals 0.08

For a school fund raising project, Aiden and Jacob collected money in the ratio of 3.5 : 6.8. Jacob collected $115.50 more than Aiden. Find the total amount of money they collected.

Answers

x - the amount of money collected by Aiden
y - the amount of money collected by Jacob

Aiden and Jacob collected money in the ratio of 3.5 : 6.8.
$(x)/(y)=(3.5)/(6.8) \n6.8x=3.5y \nx=(3.5)/(6.8)y \n x=(35)/(68)y$

Jacob collected $115.50 more than Aiden.
$x+115.5=y \nx=y-115.5 \n \nx=x \n(35)/(68)y=y-115.5 \n(35)/(68)y-y=-115.5 \n(35)/(68)y-(68)/(68)y=-115.5 \n-(33)/(68)y=-115.5 \ny=-115.5 * (-(68)/(33)) \ny=238 \n \nx=y-115.5=238-115.5=122.5 \n \nx+y=238+122.5=360.5$

The total amount of money they collected is $360.50.
