Answer:
1.03x
Step-by-step explanation:
1 year b would be the inital investment added with interest
i believe this is the equation
b = x + r(x)= (1 + r)x
and since it says 3% each year we know its 0.03 (r)
and when you solve it out you get that answer
Answer:
A. 0 and 6
Step-by-step explanation:
We look for values of x that make the numerator zero be letting the numerator equal 0.
8x(x - 6) = 0
8x = 0 or x - 6 = 0
x = 0 or x = 6
The denominator excludes x = -2 and x = -9 from the domain, but since the zeros are not those values, the values excluded from the domain do not affect the zeros of the function.
Answer: A. 0 and 6
Answer:
x = - 12, x = 2
Step-by-step explanation:
Given
x² + 10x = 24
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(5)x + 25 = 24 + 25
(x + 5)² = 49 ( take the square root of both sides )
x + 5 = ± = ± 7 ( subtract 5 from both sides )

Answer: (n + 5)(n - 5)
Explanation: In this problem, we have a binomial that's the difference of two squares because n² and 25 are both perfect squares and we are subtracting or taking the difference of these two squares.
Since the difference of two squares factors as the product of two binomials, we can setup our parenthses and in the first position, we use the factors of n² that are the same which are n · n.
In the second position, we use +5 and -5 as our factors of -25.
So our answer is (n + 5)(n - 5).
Answer:
D
Step-by-step explanation:
7x2-2x+3 = 5x2-10
7x2-2x+3+10=5x2-10+10
7x2-2x+13=5x2
7x2-5x2-2x+13=5x2-5x2
2x2-2x+13=0
