The equation of an elementary exponential function with base b is
y=b∧x with domain Dx=R or x∈R. (R set of real numbers).
Good luck!!!
Solve for x:
x/5 - 10 = 30
Put each term in x/5 - 10 over the common denominator 5: x/5 - 10 = x/5 - (50)/5:
x/5 - (50)/5 = 30
x/5 - (50)/5 = (x - 50)/5:
(x - 50)/5 = 30
Multiply both sides of (x - 50)/5 = 30 by 5:
(5 (x - 50))/5 = 5×30
(5 (x - 50))/5 = 5/5×(x - 50) = x - 50:
x - 50 = 5×30
5×30 = 150:
x - 50 = 150
Add 50 to both sides:
x + (50 - 50) = 50 + 150
50 - 50 = 0:
x = 150 + 50
150 + 50 = 200:
Answer: x = 200
There's a 75% chance of 240,000 and a 25% chance of 0 so an expected value of
.75(240000) + .25(0) = $180,000
This is less than the cost of $196,000 so the company should not make this product.
Answer:560
Step-by-step explanation:
Let a be the number of students the school have last year
135% of a=756
135/100 x a=756
135a/100=756
Cross multiplying we get
135a=756 x100
135a=75600
Divide both sides by 135
135a/135=75600/135
a=560
