Step-by-step explanation:
first you can 1.9 7 times then you do it again but to the 10 power
The 5 is the number of years that the interest rate is fixed (at the initial amount set when you sign the mortgage contract)
The 1 represents the idea that the interest rate will change every year after the initial 5 years are up.
9 students in the class play in the school band.
30% of 30
Well, when doing a percentage you first turn the percentage into a decimal (move the % two units to the left). So 30% = 0.3
In math, the word of means multiplication, so: 0.3 x 30
Which equal 9.
You can also turn the percentage into a fraction, it's really up to preference.
30/100 of 30 = 3/10 of 30 = 3/10 x 30 = 3/10 x 30/1 = 9/1 or 9
Answer:
We see two intersecting lines.
It means there is one solution, it is the intersection point.
Solution is (3, 4)
It was easy to find the solution as both lines and their intersection is visible on the graph.
With two parallel lines we would have no solutions and with overlapping lines we would have infinitely many solutions.
If you only have the equations of the lines you need to compare the slopes, if they are different it means lines are intersecting at one point hence one solution.
With same slopes and different y-intercepts there is no solution.
With same slopes and y-intercepts there is infinitely many solutions.
