If the factors of a polynomial are x+8 and X+4, what values of x make that polynomial 02

Which of the following exponential functions represents the graph below?

mario62 [17]

Answer:

the graph corresponds to function "D" $f(x)=3\,(\frac{1}{5} )^x$

Step-by-step explanation:

Since the graph shown corresponds to an exponential "decay" (the function decreases as we move from left to right), the base of the exponent has to be a number smaller than 1 (one). So we examine the only two options that give such (options C and D which have fractions as the base - 1/3 and 1/5 respectively)

From there, we analyze which of the two functions satisfies the crossing of the y-axis at (0,3) which is clearly shown in the graph:

We study both:

function C at x = 0 gives:

$f(x)= 5\,(\frac{1}{3})^x\\f(0)=5\,(\frac{1}{3})^0 \\f(0)=5\,(1)\\f(0)=5$

while function D at x = 0 gives:

$f(x)= 3\,(\frac{1}{5})^x\\f(0)=3\,(\frac{1}{5})^0 \\f(0)=3\,(1)\\f(0)=3$

Therefore, the graph corresponds to function "D"

What is the value of x in the equation 8 + x = 3? −5 5 11 24

Dvinal [7]

Answer: 8 + x = 3

To solve for this, we need to get x by itself on one side of the equation.

Currently, we have 8 being added to x, so we need to perform the opposite order of equations to get rid of 8.

The opposite of +8 is -8, so subtract 8.

Remember, if you add, subract, multiply or divide by any new number, you must do it to both sides of the equation.

8 + x = 3

Subtract 8 from both sides.

8 - 8 = 0

3 - 8 = -5

We're now left with:

x = -5

Your answer is A.) -5.

Answer:

1. -3

2. 0

3. .363636

4. Non-recurring Decimal, Recurring Decimal, Decimal Fraction

5. Going in order- irrational, rational, rational, irrational, integer, integer, irrational, integer, irrational, rational, rational.

6. 8

7. 12

8. 20

9. -5

10. False, only the square roots of perfect square numbers are rational. So for example, the square root of 2 is not rational and the square root of 4 is rational.

11. No, only decimals that never end and never repeat are irrational. a decimal is rational if it can be written as a fraction or ratio of two numbers. for example: .3434343434343434

12. Yes, 9.5 can be written as a simple fraction like this: 9.5 = 192

13. 10,920

14. 40,000

15. 0.0702

16. .003

17. 18000000000 meters

18. 1- 2,000,000,000

18. 2- 3,800,000,000

19. 36, 49. or- So, the square root of 40 will be greater than 6 but less than 7.

20. You can just add the coefficients together. If the exponents are not equal, then you must make them equal by moving one of the decimals.
