Answer:
8
Step-by-step explanation:
A = 64 musicians
A*5/8 = 40 guitarists
Jazz: x
Classic: y
x=4y
x + y = 40
5y = 40
y = 8
Answer:
Subtract by 5 on both sides.
Step-by-step explanation:
x+5 = -10. if you subtract both sides by 5, you will get x+5-5=-10-5, which can be simplified to x=-15.
Answer:
Initial amount = 12
Rate of growth = 5%
value of the function when t t = 5 is 15.3
Step-by-step explanation:
The standard exponential growth equation is expressed as;
y = A(1+r)^t
A is the initial amount
r is the rate of growth
t is the time
Given the expression y = 12(1.05)^t
On comparing with the general formula;
A = 12
Hence the initial amount is 12
Also;
1 + r = 1.05
r = 1.05 -1
r = 0.05
r = 0.05 * 100
r = 5%
The rate of growth is 5%
To evaluate the function when t = 5, we will substitute t = 5 into the given function as shown;
Recall that y = A(1+r)^t
y = 12(1.05)^5
y = 12(1.2763)
y = 15.3 (to the nearest tenth)
Answer: x = 12
Step-by-step explanation:
90-6= 84
84/7= 12
Pls brainliest :)
The graph has a greater y-intercept
why? because the y intercept of the graph is where the line crosses y which would be 8 and the y intercept of an equation is the b of y=mx+b so the y Intercept of the equation is 7
