If 5^3b-1 = 5^b-3 what is the value of b?

Mathematics
1 answer:
Tanzania [10]4 years ago
7 0

Answer:

  b = -1

Step-by-step explanation:

Your equation is ...

  (5^3)b -1 = 5^b -3

This is a mix of exponential and linear terms, and cannot be solved algebraically.

___

We suspect you might mean ...

  5^(3b -1) = 5^(b -3)

We can equate the exponents to find a value for b:

  3b -1 = b -3

  2b = -2 . . . . add 1-b to both sides

  b = -1 . . . . . . divide by 2

If the factors of a quadratic function are (x + 2) and (x − 9), what are the x-intercepts of the function?
Zielflug [23.3K]

Answer: D. (-2,0) and (9,0)

Step-by-step explanation:

When you equate the factors to 0 you get

(X+2) = 0

X = -2

(X-9) = 0

X= 9

Here the Y value is 0 as you find the factors of x when the Y value is 0.

So the answer is (-2,0) and (9,0)

Why is 2/3 greater than 3/5? Explain this to an 8 year old
Dmitrij [34]

\text{Hey there!}

\bf{\frac{2}{3}=0.6\overline{6}7}\\\\ \bf{\frac{3}{5}=0.60}

\text{Reason: if you use a fraction pie chart and compare}\frac{2}{3} \text{to}\frac{3}{5}, \text{you'd see that}\frac{2}{3} \text{has more shaded areas than as for}\frac{3}{5}\text{has the least amount}

\text{Good luck on your assignment and enjoy your day!}

Find the median<br> 23 ,15, 38 ,34 ,22, 2, 21 ,27 ,26 ,14, 32, 30, 19
xxTIMURxx [149]
First put them in ascending numerical order 
2, 14, 15, 19, 22, 21, 26, 27, 23, 30, 32, 34, 38
Then start to eliminate numbers by pair (the farthest number from each side) until you get to 1 or two numbers left (in the very middle)
in this case you will be left with 26, which means that the median is 26

Which shows how the distributive property can be used to evaluate 7 times 8 and four-fifths?
IrinaK [193]

Answer:

I have no clue as to what the options were, but the answer is 61 and three-fifths.

Step-by-step explanation:

<em>Well, the fraction options were a little distorted, so I'll work it out anyway.</em>

<em />

7 • 8 4/5

7(8 + 4/5)

<em>7 • 8 is 56, and 7 • 4/5 is 28/5.</em>

56 + 28/5

<em>28/5 as a mixed-number fraction (I think that's what it's called) is 5 3/5.</em>

56 + 5 + 3/5

61 + 3/5

61 3/5 (61 and three-fifths)

There!

<em>(Sorry about not getting the options...)</em>
