(Combine Like Terms)

(−2x+5x)+(5+3)=5 ----> 3x+8=5

Subtract 8 from both sides.

3x + 8 − 8 = 5 − 8 -------> 3x = − 3

Divide both sides by 3.

\frac{3x}{3} = \frac{-3}{3}

x = −1

Just Peachy Orchard produced 1100 bushels of peaches last year. This year the owner earned $8800 from sales. He's thinking that
Slav-nsk [51]

Answer:

P(t) ={8*(1.01)^t}

Step-by-step explanation:

The number of bushels produced is given by:

B(t)= 1100(1.1)^t

The owner's income is given by:

S(t) = 8800(1.111)^t

Income is given by the price per unit multiplied by the number of units sold. Therefore, the price function can be represented as:

P(t) =\frac{S(t)}{B(t)} \\P(t) =\frac{8800(1.111)^t}{1100(1.1)^t} \\P(t) =\frac{8*1100(1.1)^t*(1.01)^t}{1100(1.1)^t}\\P(t) ={8*(1.01)^t}

Change 185% to a mixed number and reduce, if possible.
statuscvo [17]

Answer:

1 17/20

Step-by-step explanation:

Put 185 over 100. Then, Simplify. Divide 180 and 100 by 5. 180 ÷ 5 = 37 and 100 ÷ 5 = 20. Then, divide 37 by 20. Write down the the quotient as the whole number and the remainder as the numerator.

Suppose that an object moves along the y-axis so that its location is y=x2+3x at time x. (Here y is in meters and x is in second
vfiekz [6]

Answer:

a) 13 m/s

b) (15  + h) m/s

c) 15 m/s

Step-by-step explanation:

if the location is

y=x²+3*x

then the average velocity from 3 to 7 is

Δy/Δx=[y(7)-y(3)]/(7-3)=[7²+3*7- (3²+3*3)]/4= 13 m/s

then the average velocity from x=6 to to x=6+h

Δy/Δx=[y(6+h)-y(6)]/(6+h-6)=[(6+h)²+3*(6+h)- (6²+3*6)]/h= (2*6*h+3*h+h²)/h=2*6+3= (15 + h) m/s

the instantaneous velocity can be found taking the limit of Δy/Δx when h→0. Then

when h→0 , limit Δy/Δx= (15 + h) m/s = 15 m/s

then v= 15 m/s

also can be found taking the derivative of y in x=6

v=dy/dx=2*x+3

for x=6

v=dy/dx=2*6+3 = 12+3=15 m/s
