If 3x-y=12, what is the value of
[tex] \frac{8 ^{x} }{2^{y} } [/tex]
A) 2^12
B) 4^4
C) 8^2
D) The value cannot be determined for the information​

Answers

Answer 1

Answer:

2¹² (Option A)

Step-by-step explanation:

__________________________________________________________

FACTS TO KNOW BEFORE SOLVING :-

Any number having 0 as its exponent , the overall result will be 1. For e.g. :- [tex]a^0 = 1[/tex] (where 'a' is any number).Lets say there's a number 'a' having '- x' as its exponent , then - [tex]\frac{1}{a^{-x}} = a^x[/tex]

__________________________________________________________

Lets put random values in place of x.

Let x be 0.

Putting x = 0 in the eqn. 3x - y = 12 gives the value of y.

[tex]=> 3 \times 0 - y = 12[/tex]

[tex]=> -y = 12[/tex]

[tex]=> y = -12[/tex]

So, we can conclude that by putting x = 0 , we get y = -12.

Now , putting x = 0 & y = -12 in  [tex]\frac{8^x}{2^y}[/tex]  gives -

[tex]=> \frac{8^0}{2^{-12}} = \frac{1}{2^{-12}} = 2^{12}[/tex]

Plz help me do this. Thank you in advance. Do the ordered pairs as well :)

Answers

Answer:

y=3*(-2)                                      

y=--(3*2)

y=-6

 y=-6

y=0x-6

y=0x+(-6)

y=0x+(-6),m=0

y=0x+(-6),m=0,b=-6

m=0,b=-6

  y=3x(-2)

Let x be the domain values.

Let x = -1

y = 3(-1) - 2

y = -6 - 2

y = -8...range

Our first ordered pair is (-1, -8).

Let x = 2

y = 3(2) - 2

y = 6 - 2

y = 4...range

Our second ordered pair is (2, 4).

Let x = 4

y = 3(4) - 2

y = 12 - 2

y = 10...range

Our third ordered pair is (4, 10).

Paul finished his 800 meter race in 2 minutes and 2 seconds. Jeff finished in 121 seconds. Who finished first? (PLESES SHOW WORK)

Answers

Answer:

Jeff finished first

Step-by-step explanation:

To solve this equation, I can either converts 2 minutes 2 seconds to seconds or convert 121 seconds to minutes

CONVERT 2 MINUTES 2 SECONDS TO SECONDS

60 seconds = 1 minutes

to convert 2 minutes 2 seconds to seconds, multiply 2 minutes by 60 and then add 2 seconds to it

2 x 60 = 120 seconds

120 seconds + 2 seconds = 122 seconds

Paul finished in 122 seconds while Jeff finished in 121 seconds. Jeff finished first

CONVERT 121 SECONDS TO MINUTES

60 seconds = 1 minutes

To convert 121 seconds to minutes, we have to divide by 60

121/60 = 2 minutes 1 second

Paul finished the race in 2 minutes 2 seconds while eff finished the race in 2 minutes 1 second. Jeff finished first

Becky borrowed $580.00 from the bank. The loan had a 13.5% simple annual interest rate, and she paid off the bill over 1.5 years. What was the total amount, including interest, Becky paid for the loan?

Answers

Answer:

697.45

Step-by-step explanation:

interest for the first year = 13.5 % of 580 = 78.3

for 0.5 year, it will be 78.3 /2 =39.15

1year + 0.5 year = 78.3 + 39.15= 117.45

add that to borrowed amount to get total amount paid

117.45+ 580= 697.45

If a+b = c which of the following statements is true?

b-c=a

a-c=b

c-a=b

c+b= a

Answers

Answer:

c-a=B

Step-by-step explanation:

if A+B=c then you subtract a from c and you get b

Answer:

C. c - a = b

Step-by-step explanation:

a + b = c

There are many ways to rearrange this equation. This can be done through addition and subtraction.

First, let's handle a. a is positive; therefore, we should subtract it.

a + b = c

b = c - a

Next, let's handle b. b is also positive; therefore, we should subtract it.

a + b = c

a = c - b

Finally, we will handle c. c is once again positive; therefore we should subtract it. However, it is the only variable on the right side, which would leave 0. This is not an option, so we will not look at this.

From our options, we can see that we have produced: b = c - a

This is an option, which has been written as c - a = b.

Therefore, your answer is C. c - a = b
