Answer:

y = -2

Step-by-step explanation:

Add up the coefficients of the three y terms:

(1 + 3 + 5)y = -18.

Then (9)y = -18.

Dividing both sides b y 9, we get:

y = -18/9, or y = -2.

Answer:

y=-2

Step-by-step explanation:

In order to find out the value of y, we have to isolate the y. In order to do that, we first have to combine all like terms and we do that by adding the numbers with variables together.

1y+3y+5y=9y

9y=-18

Now we have to get the y by itself so we divide 9 on both sides of the equation because once we do that, we can cancel out the 9.

9/9=1 -18/9=-2

So the answer is y=-2.

Use the coordinate grid to determine the coordinates of point A;
faltersainse [42]

Answer:

Step-by-step explanation:

The coordinates of point P are (-1.4,0.6)

Step-by-step explanation:

We are given A coordinate grid shown from negative 2 to positive 2 on x-axis and negative 2 to positive 2 on y-axis. There are 4 grid lines between a whole unit of the grid.

that means each grid has a value of 0.2.

" A point labeled P is shown at the intersection of 7 grid lines to the left of the y-axis and 3 grid lines above the x-axis "

As P lies on the left of the y-axis and above the x-axis hence the x-value will be negative and y-value will be positive.

According to the given information P lies 7 grid lines to the left of y-axis.

i.e. it has x-value -7×0.2= -1.4

and 3 grid lines above the x-axis i.e. it has y-value:

y-value= 3×0.2=0.6

Hence, the coordinates of Point P are (-1.4,0.6).
