Answers
Answer:
f(x) = 50000*2^x3 daysStep-by-step explanation:
Given:
Initial amount of bacteria = 50000Growth rate = 2 times a dayRequired equation:
f(x) = 50000*2^xSolve for x:
400000 = 50000*2^x2^x = 400000/500002^x = 82^x = 2^3x = 3After 3 days bacteria numbers will reach 400000

Two angles are vertical if one is 5x - 15 and the second angle is 3x + 1, what is the value of x
What is the measure of each angle
Answers
Answer:
Step-by-step explanation:
If they are vertical angles, they are opposite to each other where two lines intersect. Vertical angles are equal to each other so
5x-15=3x+1
2x-15=1
2x=16
x=8 degrees.
The angles are
a=5x-15, and x=8 so
a=5(8)-15
a=40-15
a=25 degrees.

Traveon is walking dogs for his neighbors, to make money. This week, he walked Mr. Jackson's dog 3.5 times farther than he walk Ms. Evans' dog. If the total distance that he walked both dogs is 17.5 miles, how far did he walk Ms. Evans' dog? *
Answers
Answer:
He walked Ms. Evans' dog 3.89 miles.
Step-by-step explanation:
From the information provided, you know that the total distance that he walked both dogs is 17.5 miles, which can be expressed as:
x+y=17.5, where:
x is the distance he walked Mr. Jackson's dog
y is the distance he walked Ms. Evans' dog
Also, the statement indicates that he walked Mr. Jackson's dog 3.5 times farther than he walk Ms. Evans' dog and you can write the following equation:
x=3.5y
Now, you can replace x=3.5y in the first formula and solve for y to find how far he walked Ms. Evans' dog:
3.5y+y=17.5
4.5y=17.5
y=17.5/4.5
y=3.89
According to this, the answer is that he walked Ms. Evans' dog 3.89 miles.

We want to see which of the given values is a solution of the inequality:
x < 4
The correct option is A, x = 3.
Finding the solution:
So the inequality:
x < 4
This means that the variable must be a number smaller than 4.
Then we just need to select the option that is smaller than 4, the only option that meets this requirement is option A, x = 3
Also, as you can see in the number line, the only number that is in the shaded part is x = 3 (from the ones in the options).

A local shelter is having an Adopt-a-thon for kittens and puppies. Kittens cost $50 to adopt and puppies are $75. The shelter made $1200 during the Adopt-a-thon event and adopted off twice as many puppies as kittens. Write and solve a system to find how many puppies and kittens were adopted
Answers
Answer:
Step-by-step explanation:
P=2K
50K+75P=1200, using P from above makes this equation become
50K+75(2K)=1200
50K+150K=1200
200K=1200
K=6, since P=2K
P=2(6)=12
So 12 puppies and 6 kittens were adopted.

Lets test the first equation and coordinate #1 first, 3x-2y=12, and (10,9).
Here we can substitute x as 10 and y as 9, and solve the equation to see if 3(10)-2(9) equals 12 or not.
30-18=12, yep
now lets test the second coordinate, (0, -6). Substitute x as 0 and y as -6, and solve the equation.
3(0)-2(-6)=12
0+12=12, yep
So I definitely works
For II, lets do the same thing
(10, 9) -- 9=3/2*10-6
9=15-6, works
(0, -6) — -6= 3/2*0-6
-6=0-6, also works
So uh therefore I and II both work you see what I mean-

Solve for x in the diagram below.
Answers
Answer:
x = 20
Step-by-step explanation:
The sum of the two angles is 90 degrees
x+3x+10 = 90
Combine like terms
4x+10 = 90
Subtract 10 from each side
4x+10-10 = 90-10
4x= 80
Divide each side by 4
4x/4 = 80/4
x = 20
Answer:
x = 20
Step-by-step explanation:
x and 3x + 10 form a right angle, then
x + 3x + 10 = 90
4x + 10 = 90 ( subtract 10 from both sides )
4x = 80 ( divide both sides by 4 )
x = 20
