Answer:

k(-1) = 7

Step-by-step explanation:

the blue line represents the graph of k. The question is asking what the y-value at x=-1 is. Therefore, you just look at the blue line when x = -1, which is one block to the left of the middle. At that point, the y value is 7.

HELP PLS A carnival charges $2.50 per ride after an entrance fee.You paid a total of $22.50 after 6 rides.Find the total cost fo
Finger [1]
The cost of the entrance would be 7.5$, because 2.50$ x 6 equals 15.

Let’s multiply 6 x 2 to get twelve, and if six rides are 15$, that would be 30$ for twelve rides. But we still have three more.

2.50 x 3 would be 7.5$, and if we add that to 30$, we would get 37.5$.

With entry fee though, we would add 37.5$ to
7.5$, and so it would be 45$ on the dot.

Your answer would be 37.5$ without entry fee, and 45$ with entry fee.

Please help me! I would really appreciate it

Answer:

D

Step-by-step explanation:

Using the rule of exponents

(a^nb^n)^{m} = a^{(mn)}b^{(mn)}, hence

(a^{\frac{1}{2} }b^{\frac{1}{3} })^(\frac{1}{2})

= a^{\frac{1}{2}(\frac{1}{2} ) } × b^{\frac{1}{3}(\frac{1}{2})  }

= a^{\frac{1}{4} } b^{\frac{1}{6} } → D
