Answer:

$352.80

Step-by-step explanation:

We have been given a family sell back 420 kWh for $0.07 per kWh each month.

First of all, we will find monthly income of family from solar panels by multiplying 420 by $0.07.

\text{Monthly income of family from solar panels}=420\text{ kWh}\times \frac{\$0.07}{\text{kWh}}

\text{Monthly income of family from solar panels}=420\times\$0.07

\text{Monthly income of family from solar panels}=\$29.40

To find the money earned by the family is one year, we will multiply monthly income by 12 as 1 year equals to 12 months.

\text{Annual income of family from solar panels}=\$29.40\times 12

\text{Annual income of family from solar panels}=\$352.80

Therefore, the family could make $352.80 in a year from solar panels.

Having trouble w graphing :(
NISA [10]

6x/6=x>/= (=) 11/6

x=11/6 or about 1.8

the first important notation to remember when graphing inequalities is that the graph is going to face the way the inequality sign is pointing.

in this case, the sign is pointing right. now the second thing to remember is that an inequality sign with a line underneath it means that it is greater/equal to so the graph in which we fill will have be a closed circle

1) start the ray at ~1.8 and fill in the circle at the end of the ray then extend to its endpoint

that's all. you're graph now reads  x is greater or equal to 11/6
