Part A: If (7exponent2)exponentX = 1, what is the value of X? Explain your answer.

yKpoI14uk [10]

Answers:
Part A: The value of x must be 0
Part B: The value of x can be any real number

----------------------------------------------------------------

Explanation:

Part A) We have the equation (7^2)^x = 1 which simplifies to 7^(2x) = 1. The only way to get the left side equal to the right side is to have the exponent of 2x equal zero. If 2x = 0, then x = 0. So that's why x = 0 is the only solution here.

--------------

Part B) Similar to part A above, but the exponent is slightly different now. We have (7^0)^x = 1 which turns into 7^(0*x) = 1. The exponent 0*x is really 0 no matter what x is. We can plug in any real number we want for x and the left side will always be 1. This is why the solution set to this equation is the set of all real numbers.

Ravi purchased n notebooks. They were 5 dollars each. Write an equation to represent the total cost c that Ravi paid

Veseljchak [2.6K]

c = 5n

the cost (c) would equal (=) the number or notebooks (n) times $5 (5) because each is five dollars.

Kyle determines that y ≥ − 8/3 x-4 is shown on the graph. Is Kyle correct? If not, determine the correct inequality.

Troyanec [42]

Answer:

C) No, Kyle is incorrect. The correct inequality is $\displaystyle y > -\frac{8}{3}x - 4$

Step-by-step explanation:

This graph has a dashed line, so it would be either less than or greater than. The only way to find out is to use the zero-interval test [test point (0, 0)] to ensure whether we share the opposite portion [the portion that does not contain the origin] or the portion that DOES contain the origin. This is where we verify the inequality as false or true:

Greater than

$\displaystyle 0 > -\frac{8}{3} - 4 → 0 > -4$ ☑
