<h3><u>4</u><u>.</u><u> </u><u>m²</u><u>n</u><u>²</u><u> </u><u>-</u><u> </u><u>1</u></h3>
Rewrite m²n² - 1 as . The difference of squares can be factored using the rule: .
The first thing you have to do is know the equation. The equation is a(1+p)^t.
a= the amount of money p= the percent represented as a decimal and t=time ( the t is raised as an exponent)
so, in this case, it is represented as 200(1+0.05)^2\
200(1.05)^2
200(1.1025)
220.5 That is how much extra he would owe in interest fee's
Answer:
x > 10/7 or x > 1 3/7
Step-by-step explanation:
First simplify the left side of the inequality.
6x+ 1/4 (4x+8)> 12
6x+x+2>12
7x+2>12 Next, using the property of inequality, subtract two from both sides.
7x>10 Now divide by 7 to solve for x.
x>10/7 or x> 1 3/7
Answer:
15 feet above ground.
Step-by-step explanation:
15 feet - 4 feet = 11 feet
11 feet + 5 feet = 16 feet
16 feet - 1 foot = 15 feet
To find the x intercept, sub in 0 for y and solve for x
2x - 5y = 20
2x - 5(0) = 20
2x = 20
x = 20/2
x = 10....x intercept is (10,0)
to find the y intercept, sub in 0 for x and solve for y
2x - 5y = 20
2(0) - 5y = 20
-5y = 20
y = -20/5
y = -4....y intercept is (0,-4)
