Answer:

x = 2 (For First question)

Step-by-step explanation:

8^ 1/6 * 2^x = 32^1/2

8^1/6 * 2^x 8^1/6 = 32^1/2/8^1/6

2^x = 32^1/2 / 8^1/6

2^x = 4

2^x = 2^2

x =2

Question 2:

Answer: 50

Step-by-step explanation:

8^1/3/5^-2

= 2/5^-2

= 2/1/5^2

= 2* 5^2/1

= 2 * 5^2

= 2 * 25

= 50

You roll a fair 6-sided die what is p (not 3)

Ulleksa [173]

As a fraction, the exact answer is 5/6
In decimal form, the approximate answer is 0.8333

To get this answer, note how there are 5 ways to roll something that isn't a three (1,2,4,5,6) out of 6 ways total (1,2,3,4,5,6)

So you simply divide the two values to get 5/6 = 0.8333

Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point (-5, 0)

Point (-9, -8)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{-8-0}{-9+5}$
[Fraction] Subtract/Add: $\displaystyle m=\frac{-8}{-4}$
[Fraction] Divide: $\displaystyle m=2$

Arnav knows that (3, 4, 5) and (5, 12, 13) are Pythagorean triples. He wants to show that (15, 20, 25) is also a Pythagorean tri

Answer:

multiply the (3, 4, 5) triple by 5 to get (15, 20, 25)

Step-by-step explanation:

Any multiple of a Pythagorean triple is a Pythagorean triple.

5(3, 4, 5) = (5·3, 5·4, 5·5) = (15, 20, 25) — a Pythagorean triple

Do the side lengths 9,12,15 classify as a right,acute,obtuse triangle, or “no possible triangle”

HACTEHA [7]

Refer to c^2=a^2+b^2 (^2 means squared)
C is the hypotenuse and will be the longest measure
So 15^2= 9^2+12^2
225=225
If both sides are equal then the triangle is a right triangle, if the hypotenuse (or c) is lower or higher than you can determine whether it’s obtuse or acute
It would be a right triangle
