You want to isolate the variable 'y'.

\sf -3y+10=-14

Subtract 10 to both sides:

\sf -3y=-24

Divide -3 to both sides:

\sf y=\boxed{\sf 8}

To solve -3y+10=-14, isolate variable y

In order to isolate y, move everything from the left side of the equation to the right side of the equal sign. This can be done by performing the opposite math operation than the one listed. The variable will not be transferred over to the other side.

 -3y+10=-14

Subtract 10 from the left and right side

 -3y=-24

Divide -3 from both sides in order to isolate y

 y=8

How to get the answer to 2/3(3x+6)=4x+3 without using distributive property.
Annette [7]

The answer for the given equation is x = 3.5.

<u>Step-by-step explanation</u>:

Given, 2 / 3 (3x + 6) = 4x + 3

Step 1:

Rearranging the given equation by subtracting the right side of the equation to the left side.

                           2 / 3 (3x + 6) - 4x + 3 = 0

Step 2:

Taking out the like terms, the equation becomes

                          (2 / 3) \times 3 (x + 2) - (4x - 3) = 0

                          ⇒   2 (x + 2) - (4x - 3) = 0

Step 3:

Solving the equation for the value of x,

                          ⇒    2x + 4 - 4x + 3 = 0

                          ⇒    -2x + 7 = 0

                          ⇒     -2x = -7

                          ⇒     x = 7 / 2 = 3.5.

Hence the value of x = 3.5.

If the equation of the regression line for the data set (3,4), (6,2), (9,18) is , what is the sse for the data set?
Licemer1 [7]

Answer:

38.9

Step-by-step explanation:

Lets say, first number = x


Second number = 3x+7


Total = 49



(x)+(3x+7)= 49


4x+7 = 49


4x = 42


x = 42/4


x= 10.5



x= 10.5


3x+7 = 3(10.5)+7 = 38.9



Hope this helps!!

Two trains leave stations 342 miles apart at the same time and travel toward each other. One train travels at 105 miles per hour
Rasek [7]

Answer:

1.8 hours.

Step-by-step explanation:

It is important to note that:

Speed = Distance ÷ Time

We have two trains.

Step 1

We have to find the distance that each train travelled.

Since Speed = Distance ÷ Time

Distance = Speed × Time

First train

It travels at 105 miles per hour

Distance travelled by first train =

105 × x hours

= 105x miles

Second Train

It travels at 85 miles per hour

Distance travelled by the second train = 85 miles × x hours

= 85x miles

We are told that: the two trains leave stations 342 miles apart at the same time and travel toward each other

Hence, the time it would take each train to meet each other is calculated as:

105x + 85x = 342 miles

190x = 342 miles

x = 342/190

x = 1.8 hours.
