Answer:
Step-by-step explanation:
Given the exponential function:
P(t) = 500,000 * e^(-0.099t)
P(t) = population t years later
When population will be one-half the initial amount
Half the initial amount = 500000/2 = 250,000
250000 = 500000 * e^(-0.099t)
250000/50000 = e^(-0.099t)
0.5 = e^(-0.099t)
Take the In of both sides
In(0.5) = - 0.099t
−0.693147 = - 0.099t
0.693147 / 0.099 = t
t =

Lucy bought a table on sale for $665. This price was 24% less than the original price.
What was the original price?
Answer: Below
Step-by-step explanation:
24% is basically 0.24. Since we want to find the original price we make the equation:
x * (1 - 0.24) = 665
For x is the original price. Simplify:
x * (0.76) = 665
x = 665/0.76
x = 875
Our answer is 875
Convert the following equation into standard form.
[tex]y = - \frac{4x}{9} + 3[/tex]
Move the expression to the left-hand side and change its sign
[tex]y + \frac{4x}{9} = 3[/tex]
Multiply both sides of the equation by 9
[tex]9y + 4x = 27[/tex]
Use the commutative property to reorder the terms
[tex] \underline{ \underline{4x + 9y-27 = 0}}[/tex]
Standard form of a line:-
Ax+By+C=0[tex]\\ \rm\Rrightarrow y=\dfrac{-4x}{9}+3[/tex]
[tex]\\ \rm\Rrightarrow y=\dfrac{-4x+27}{9}[/tex]
[tex]\\ \rm\Rrightarrow 9y=-4x+27[/tex]
[tex]\\ \rm\Rrightarrow 4x+9y-27=0[/tex]

Solve using substitution.
4x + y = –11
4x + 4y = 16
Answer:
1) -11/4 - y/4
2) x= 4 - y
Step-by-step explanation:
Answer:
1. x = - 11/4
2. x = 4
1/5 (x - 8) equals x - 16
Answer:
I have no idea if you are saying that x=16. If it does the answer is 8/5
Answer:
x-8=5x-80
8+80=5x-x
88=4x
x=88/4
x=22

Mrs. Gildner took a survey of the 30 students in her math class. Of the 30 students surveyed, 18 of them said that chocolate is their favorite ice cream flavor. 4 students listed vanilla as their favorite flavor. The remaining students indicated that strawberry is their favorite kind of ice cream.
What is the ratio of chocolate to strawberry? SIMPLIFY if possible!
Answer: 9:4
Step-by-step explanation: Total is 30. Add 18 and 4 to see how many students were already surveyed, (22) and then subtract that from 30. Then you get 8, so the ratio is 18:8. Then simplify by dividing both numbers by 2, so you get 9:4. Hope that helps :)

What is an equation of the line that passes through the points (5,2) and (-5,-6) PLEASE ANSWER
Answer:
y = 4/5 x - 2
Step-by-step explanation:
Find for slope first:
m = (y2 - y1) / (x2 - x1)
= [(-6) - 2] / [(-5) - 2]
= -8/-10
= 4/5
Solve for b. Use (5, 2)
y = mx + b
2 = 4/5 (5) + b
2 = 20/5 + b
2 = 4 + b
2 - 4 = b
-2 = b
Substitute the value of m and b.
y = mx + b
y = 4/5 x + (-2)
y = 4/5 x - 2

Identify the value of y.
9y+6 = 3y+3+7+26
Answer:
y=5
Step-by-step explanation:
9y+6 = 3y+3+7+26
arrange the equation so all values with y are on one side, and all regular numbers are on the other side. Make sure you change the sign when changing sides.
9y - 3y = 3 + 7 + 26 -6
6y / 6 = 30 / 6
Now divide both sides by 6 in order for y to be alone.
y = 5
