Answer:
y = -5 and x = -17
Step-by-step explanation:
We want to solve these two equations,
x = 3y - 2
x = 5y + 8
We can see that they both equal x so we want make them equal to each other so,
→ 3y - 2 = 5y + 8
⇒ Subtract 5y from both sides to collect the 'y' terms
→ -2y - 2 = 8
⇒ Add 2 both sides to collect the numerical terms
→ -2y = 10
⇒ Divide both sides by -2 to isolate y
→ y = -5
Now that we have found the value of y we can substitute this value into one of the 2 equations we have to find the value of x
⇒ We know that y = -5 so lets substitute that into x = 3y - 2
→ x = 3 × -5 - 2
⇒ Simplify
→ x = -15 - 2
⇒ Simplify further
→ x = - 17
The answer to the question is 459.32 i think
Divide by 2 to get
5^x = 7
Now take the logarithm.
x·log(5) = log(7)
x = log(7)/log(5) ≈ 1.209062
Answer: $543.7325
Step-by-step explanation:
room rate = $99.95 / night
Tax fee = 7% of room rate
Therefore, tax fee = 7% of $99.95
Tax fee = 0.07 × $99.95
Room charge =[$99.95 + 0.07($99.95)]
Room charge = 1.07($99.95) per night
Additional onetime untaxed fee = $9
Therefore for 5 nights :
Room charge = 5×[1.07($99.95)] +
Total room charge = 5×[1.07($99.95)] + one time untaxed fee
Total room charge = 5×[1.07($99.95)] + $9
= $543.7325
Subtract:
10,010-10=10,000
Your answer is 10,000.
Hope that helped:D
