ANSWER
The solution is
<u>EXPLANATION</u>
We have
and
Let us substitute equation (1) in to equation (2). This gives us,
We rewrite this as a quadratic equation as the highest degree is 2.
This implies that
we factor to obtain,
This means,
We substitute this values into any of the above equations, preferably equation (1)
When, ,
When, ,
The solution is
Answer:
y=3^x+1
Step-by-step explanation:
y=3^x+1
do the graph for each equation
or input point : when x=0, y=2 , when x=1 , y=4
Answer:
2/3 hour
Step-by-step explanation:
We can add the fractions, then multiply by the time, or we can multiply each by the time and add the results.
(1/5 +1/3)(1 1/4) = (8/15)(5/4) = (4·2·5)/(3·5·4) = 2/3 . . . hours
alternatively, ...
(1/5)(1 1/4) +(1/3)(1 1/4) = (1/5)(5/4) +(1/3)(5/4)
= 1/4 +5/12 = 3/12 +5/12 = 8/12 = 2/3 . . . hours
It takes Marty 2/3 hours (40 minutes) to shower and eat breakfast.
Let x = width of border
Area is given to be 7 square feet or 49.
49 = (2x + 2)(2x + 4)
Solve for x.
The inequality says that the sum of the two numbers is zero or more.
Find one of the pairs where the sum of the two numbers is zero or more,
and that will be the one you're looking for.
