Answer:

y=x/3 - 4

Step-by-step explanation:

add x to get x to the other side

3y= x-12

divide by 3 on both sides to get y by itself y= x/3 - 4 is simplest form

Answer:

slope intercept form is y=mx+b

add x to both sides : 3y=x-12

divide by 3 on both sides : y=(1/3)x-4

nnnd i put both equations in desmos n they r the same :)

-9y-27=2y+39

Add 9y on both side

-27=11y+39

Sub 39 from each side

-66=11y

Translate the following problem into an equation: (1) together Jon and Amy spent $29 dollars on a birthday gift. (2) Jon spent $

kolbaska11 [484]

Let the money spent by John = y
and Amy=x

ATQ

x+y = $29

It is given that jon spend 5 more than Amy. SO he spend

x +5

x+y = $29
x+x+5=$29

2x = 29-5

2x= 24

x = 24/2 =12

So Amy spend $ 12 and Jon spend x+5 = 12+5 = $17

When Klorina swims with the current, she swims 10 km in 2 h. Against the current, she can swim only 8 km in the same time. How f

nasty-shy [4]

Answer:

Klorina's rate in still water is 4.5 km/h

Current's rate is 0.5 km/h

Step-by-step explanation:

Let

x km/h = Klorina's rate in still water

y km/h = current's rate

With the current (current helps):

Distance = 10 km

Time = 2 hours

Rate = x + y km/h

$10=2(x+y)$

Against the current:

Distance = 8 km

Time = 2 hours

Rate = x - y km/h

$8=2(x-y)$

Divide both equations by 2:

$x+y=5\\ \\x-y=4$

Add these equations:

$x+y+x-y=5+4\\ \\2x=9\\ \\x=4.5\ km/h$

Subtract these two equations:

$(x+y)-(x-y)=5-4\\ \\x+y-x+y=1\\ \\2y=1\\ \\y=0.5\ km/h$
