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]

Solve for k, the constant of variation, in an inverse variation problem where y=17 x=6
Answer:
k = 102
Step-by-step explanation:
Inverse variation is represented as follows:
y = k/x
Find k by substituting 17 for y and 6 for x:
17 = k/6
Multiplying both sides by 6 results in k = 102

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

sin 2A + sin 5A-sin A÷
cos A + cos 2A + cos 5A
Answer:
Step-by-step explanation:
(sin5a-sina)+sin2a/(cos5a+cosa)+cos2a
=2cos3asin2a+sin2a/2cos3acos2a+cos2a
=sin2a(2cos3a+1)/cos2a(2cos3a+1)
=sin2a/cos2a
=tan2a

i bought a box of air head worth $7.98 there are 60 bars in the box, how much is 1 air head worth? please help
Answer:
$0.13
Step-by-step explanation:
7.98/60 = 0.133
round down to 0.13
Answer:
I believe the answer is $0.13
Step-by-step explanation:
You need to divide the price of the air heads ($7.98) by how many bars there were in the box (60). 7.98/60= 0.133
Then you round the answer to the nearest hundredth: 0.133= $0.13
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?
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

Given that m∠a = 53°, find m∠b.
m∠b =
°
Answer: 143
90-53=37
180-37=143
Answer:
Step-by-step explanation:
The angle left to b is
90° - a
= 90° - 53°
= 37°
So now
< b + 37° = 180° ( being linear pair )
< b = 180° - 37°
< b = 143°
Plz help me do this. Thank you in advance. Do the ordered pairs as well :)
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).
Done.

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