What is the value of the y-coordinate in this system of linear equations:6x+10y=-32 and 6x+9y=-27

x=3,y=-5

Step-by-step explanation:

Simultaneous equation

We will have to solve this using elimination method

6x+10y=-32...(1)

6x+9y=-27...(2)

We will start solving by eliminating x

Therefore substrate (2) from (1)

y=-5

So Let's substitute the value of y into (2)

6x+9(-5)=-27

6x-45=-27

Add 45 to both sides

6x=18

Make x the subject of formula by dividing both sides by 6

x=3

Therefore x=3,y=-5

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
