Answer:
24
Step-by-step explanation:
- 3x - 15 = x + 33 [sides opposite congruent angles in a triangle are congruent]
- 2x - 15 = 33 [subtract x from both sides]
- 2x = 48 [add 15 to both sides]
- x = 24 [divide both sides by 2]
- BC = 24 [BC = x]
Answer:
5. f(x) = 10,000 (1.5)^x
Step-by-step explanation:
We would have to multiply the original amount by 1.50^x because the initial amount would be 1, and 50% increase would be .5 so 1.5 and you raise it to the number of years to show the total increase.
Let's test it.
Initial:
10,000
After 1 year
10,000 + (.5*10000)
10,000 + 5000 = 15,000
After 2 years
15,000 + (.5*15000)
15,000 + 7500 = 22,500
Let's try our equation.
f(x) = 10,000 (1.5)^x
x = 2
10,000(1.5)^2
10,000(2.25) = 22,500
The same!
Answer:
x+y=5a
5a is added to b which is the sum of x and y multiplied by 3. That is, b=x+y×3=5a×3=15a
Since, 5a is added to b= 5a+15a=20a,
Answer:
y=3x+3
