Answer:
x=10
Step-by-step explanation:
Using Pythagorean theorem,
(√13^2-12^2)×2
(√169-144)×2
(√25)×2
5×2=10
Answer:
68
Step-by-step explanation:
f(x) = 7x + 5
= 7(9) + 5
= 63 + 5
= 68
Answer:

Step-by-step explanation:
According to the Definition of Rational Exponents, use this formula to rewrite this as an exponential expression:
![a^{\frac{m}{n}} = \sqrt[n]{a}^{m}](https://tex.z-dn.net/?f=a%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D%20%3D%20%5Csqrt%5Bn%5D%7Ba%7D%5E%7Bm%7D)
NOTE: Since we have exponents in our radical, we have to multiply all exponents by one-half, since raising something to its <em>half power</em> is the exact same as taking the <em>square root</em> of something:
![[{n}^{3}{p}^{4}]^{\frac{1}{2}} = {n}^{1\frac{1}{2}}{p}^{2}](https://tex.z-dn.net/?f=%5B%7Bn%7D%5E%7B3%7D%7Bp%7D%5E%7B4%7D%5D%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%20%3D%20%7Bn%7D%5E%7B1%5Cfrac%7B1%7D%7B2%7D%7D%7Bp%7D%5E%7B2%7D)
* Do not forget to remove the radical in the beginning because you are once again, rewriting this as an exponential expression.

Answer:
Step-by-step explanation:
The objective is to isolate C (make it lonely so that its the only thing on one side of the equation)
If x is the game number, and y is the amount of touchdown passes for that specific game number, then (5,3) represents the idea that the quarter back threw y = 3 touchdown passes for game number x = 5
So the answer is choice D. This is the only ordered pair that comes from the given table. Something like (2,4) isn't true because the quarterback threw 1 touchdown pass (not 4) in game two.
