6(5 - 3x) - 5(3x + 2)

Answers

Answer:

Step-by-step explanation:

I conclude that you need to find the value of x

6(5 - 3x) - 5(3x + 2)

30 - 18x -15x -10 = 0

-33x +20 = 0

33x = -20

x = -20/33

The answer is
= −33x+20

Consider the inequality -20.2 > 0y. Which of the following must be true? Check all that apply.
1.You cannot divide by zero.
2.The inequality is equivalent to -20.2 > 0, which is false.
3.The solution is y > 0.
4.The solution is 0 > y.
5.The solution is y = 0.

Answers

Answer:

Step-by-step explanation:

1 and 2

1 because indeed you can't divide -20.2 by zero to get y

2 because the inequality is basically a false situation.

The answer is definitely 1 and 2

Which equation correctly models the relationship between hours passed, h, and the number of bacteria present, b, as shown in the table?

Amount of Bacteria

Hours # of

Passed Bacteria

0 1

1 2

2 4

3 8

4 16


A. b=2 to the h power

B. b=2 to the h power plus 1

C. b=2h

D. b=2h+1
sorry, it shows it a bit messed up. the number of hours is shown on the left side with the numbers directly below it. the number of bacteria is the second column.

Answers

Answer:

A. b = 2 to the h power

Step-by-step explanation:

For the table:

When:

h = 0, b = 1, so 1 = 2^0, 1 = 1

h = 1, b = 2, so 2 = 2^1, 2 = 2

h = 2, b = 4, so 4 = 2^2, 4 = 4

h = 3, b = 8, so 8 = 2^3, 8 = 8

h = 4, b = 16, so 16 = 2^4, 16 = 16

I got A. B=2 to the h power

which angles are complementary to each other select all that apply

Answers

Answer: 4 and 1

Step-by-step explanation:

Both ∠4 and ∠1 are equal angles. Both the angles are beside a right angle and you can measure it. The other answers are over 90 degrees, or below 90. This is because they either combine a 90 degree angle with another angle, or that they are too small and obvious that they are not complementary.

Answer:

<2 and <4

complimentary <s add up to 90 °

Which describes all decimals that are rational numbers?
A. the decimal terminates or repeats.
B. the decimal terminates and does not repeat.
C. the decimal neither terminates nor repeats.
D. the decimal repeats and does not terminate.

Answers

Answer: A. the decimal terminates or repeats.

===========================================================

Explanation:

A terminating decimal example would be something like 0.2 which converts to the rational number, aka fraction, 1/5. The word "terminate" means "stop", so it's any decimal that doesn't go on forever.

A repeating decimal is something like 0.33333 where the 3s go on forever, and that converts to 1/3.

If any of these conditions happen, then the number is rational.

--------

For something like pi = 3.14159... where there isn't a pattern and it goes on forever, then we consider this number irrational. The term "irrational" literally means "not rational". So this allows us to rule out choice C.

Choices B and D are partially true, but they only paint half the picture needed to form all rational numbers. Choice A is the most complete statement.

In other words, while choice B is technically true, it leaves out repeating decimals. Choice D is the same way but it leaves out terminating decimals. So we can rule out choices B and D.
