BIL is the answer to that one day
The given function is : y= f(x) =49 [\frac{1}{7}]^x
The statements which are true regarding this function is
1. As you can observe that y is defined for all values of x , so Domain is set of all values that x can take which is set of all real numbers.
2. Also, x =\frac {\log[\frac{y}{49}]}{-\log7}, so x is defined for all values of y. Range is all values that y can take which is also set of all real numbers greater than zero, i.e y>0.
As ,x =0 then y= 49 and x_{1} =1 then y_{1} = 7,
so ,y_{1} = \frac{y}{7}.
So, Option (1),(4) and (5) are correct.
Shoes= 10
Man= 5
Tie= 4
So, 10+5*4= 30 <— Answer
How to get variables:
Shoes:
3 shoes are equal to 30, so to find the value of the shoes use 3x=30. X=10
Man:
2 men and a shoe is equal to 20. So, 2x+10=20
2x=10
X=5
Tie:
2 ties and a man are 13. So,
2x+5=13
2x=8
X=4
Answer:
16x - 2 + y
Step-by-step explanation:
(48x - 6 + 3y)/3 = 48x/3 - 6/3 + 3y/3 = 16x - 2 + y
<span>Let x represent Harry's age now, and Nick's age now is 7x. [t]
In 6 years, Harry is x + 6 , and it is given that Nick's age will be 5(x+6). [t+6]
Combining [t] and [t+6], 7x + 6 = 5(x+6).
So the formula 7x + 6 = 5(x+6) represents the problem.
And x = 12 , so Harry's age in 6 years will be x +6 or 18 years .
I hope this helps!</span>
