Answer:
x = -2 and x = 1/3
Step-by-step explanation:
The simple way to solve this is to enter the equation into a graphing calculator and have it show you what the zeros are.
The solutions are x = -2 and x = 1/3.
__
One way to solve this is to factor it. The product of the leading coefficient and the constant is (3)(-2) = -6. You want to find factors of this number that have a sum equal to the coefficient of the linear term: 5.
-6 = (-1)(6) = (-2)(3) = ...
The first pair of factors listed here has a sum of 5, so we can rewrite the equation as ...
3x^2 -x +6x -2 = 0
Factoring pairs of terms, we have ...
x(3x -1) +2(3x -1) = 0
(x +2)(3x -1) = 0
The solutions are the values of x that make these factors zero:
x + 2 = 0 ⇒ x = -2
3x -1 = 0 ⇒ x = 1/3
The solutions are x = -2 and x = 1/3.
What is the interest is the principal is $10,000 the interest rate is 2% and the time is eight years
Answer:
the answer is 160
Step-by-step explanation:
take the interest percentage and divide by 100 ex:5.2%100=0.052
take the dollar amount and multiply interest decimal
ex:$450*0.052=23.40
take the sum of dollar amount and interest decimal and multiply by # of years of interest
ex:3 years *23.40=70.20
and that is how i got that answer

Answer:
Third choice 7(x + 2) - 3x = 2/3(6x + 3)
Step-by-step explanation:
Choice answer 1 has infinitely many solutions since -1/2(8x + 6) - 2x = -3(2x + 1) → -6x - 3 = -6x - 3 = 0 → 0 = 0 [is always equal to].
Choice answer 2 has one solution since
-1/2(8x + 6) - 2x = -3(2x + 1) → -2x - 8 = 2x - 8 → x = 0 [is equal to in 1 condition].
Choice answer 3 has no solution since
7(x + 2) - 3x = 2/3(6x + 3) → 4x + 14 = 4x + 2 → 0 = -12 [is never equal to].
Choice answer 4 has infinitely many solutions since -2x + 5 - 3x + 12 = -5(x - 3) + 2 → -5x + 17 = -5x + 17 → 0 = 0 [is always equal to].

As a restaurant manager, you are tracking the number of ketchup bottles used each week in the restaurant. For six
weeks, the number of bottles used each week were 10, 14, 11, 10, 18, and 17.
What is the mean number of ketchup bottles used in one week?
A. 8
B. 10 C. 35/3
D. 40/3
E. 14
Answer:
The mean is 40/3 ⇒ D
Step-by-step explanation:
The mean of a set of data = The sum of data ÷ the number of data
∵ A restaurant manager tracking the number of ketchup bottles in
six weeks
∴ The number of data = 6
∵ The numbers of ketchup bottles used each week are 10, 14, 11, 10, 18, 17
→ Find their sum
∴ Their sum = 10 + 14 + 11 + 10 + 18 + 17
∴ Their sum = 80
∵ The mean = The sum of data ÷ the number of data
∴ The mean = 80 ÷ 6
→ Simplify it by dividing both by 2
∴ The mean = 40/3

Enter the number of complex zeros for the polynomial function in the box.
f(x)=x4+5x2+6
Answer:
4Step-by-step explanation:
Given function
f(x)=x⁴+5x²+6Zeros of the function:
x⁴+5x²+6 = 0(x²)² + 2x² + 3x² + 6= 0(x² + 2)(x² + 3) = 01. x²+ 2 = 0
x²= -2x₁,₂ = ±√2i2. x² + 3 = 0
x² = -3x₃,₄ = ±√3iAs we see there are 4 complex zeros
