Answer:
Graph the equations
Step-by-step explanation:
x - y = 1
3x + 2y = - 12
Rewrite equations into y=mx+b form:
y = -1 + x
y = -6 - 1.5x
Graph it!
Answer:
1:17
Step-by-step explanation:
Find out how long it it between 5.30pm and 9am. This is 8 hours 30 minutes or 510 minutes.
Now, arrange them in the ratio of Lunch Break to Total office time
30:510. This can be simplified to 1:17
Please check if the question is worded correctly, just in case. Because ratio questions are usually based on a part and the remaining parts of the same thing, and not part to whole.
Anyway. The answer given if for the question you have typed.
Hope this helps.
Answer:
Reactive power is 28.8VARs
Step-by-step explanation:
We are given that in a parallel circuit,
,R=470Ω and
=500Ω
And we area asked to find reactive power.
Reactive power is power dissipated due to reactive elements in the circuit and it occurs when voltage and current are not in phase.
Reactive power = 
Answer:
y=-6/5+9
Step-by-step explanation:
your going ro put it in y=mx+b format
so it would be ur equation 12x+10y=90
subtract 12x from both sides and get 10y=-12x+90
u have to get 10 by itself so you divide 10 to everything and get y=-12/10x+90/10
you have to simplify so get y=-6/5+9
