a(b - 1)2 when a = 8 and b=4

Answers

Answer 1

Answer:

Step-by-step explanation:

Don't worry my friend, we have the power of order of operations!!

Okay, so first start by replacing the variables with the given numbers.

a(b - 1)^2 = 8(4 - 1)^2

Now do whats in the parentheses.

(4 - 1) = (3)

Next, we do 3 x 3 . This is because the three is squared.

(3)^2 = 9

Finally, multiply by 8.

8 (9) = 72

Hope this helped! Please comment wether it does or not. :)

Find the value for x that makes A parallel to B.

(I will give brainliest!) I appreciate any help

Answers

Answer:

x = 5

Step-by-step explanation:

For A to be parallel to B

the alternate exterior angles must be equal

13x - 8 = 9x + 12

Subtract 9x from both sides

4x - 8 = 12

add 8 to both sides

4x = 20

Divide both sides by 4

Hi there!

-----------------------------------------------------------------------------------------------------------------

y=2-3x

2=2-3(0)

2=2-0

2=2

So we get a true statement. So Option 1 is correct.

-5=2-3(1)

-5=2-3

-5=-1

We get a false statement. Therefore, this isn't the right ordered pair.

Now, let's try the next ordered pair:

-7=2-3(3)

-7=2-9

-7=-7

So this ordered pair is a solution of this equation as well.

Now, try the next one:

5=2-3(-1)

5=2+3

5=5

So this is a solution as well.

8=2-3(-2)

8=2+6

8=8

So this pair is a solution as well.

-3=2-3(-3)

-3=2+9

-3=11

So here, we get a false statement. Therefore, this isn't the solution.

y=-x/3-2

-4=-3/3-2

-4=-1-2

-4=-3

We get a false statement. Therefore, this isn't the solution.

(2, -6) isn't a solution as well.

Hope it helps!

The amount of pollution entering the atmosphere varies directly as the number of people living in an area. If 40,000 people create 29,600 tons of pollutants,
how many tons enter the atmosphere in a city with a population of 500,000?

Help please

Answers

Answer:

370 000

As it varies directly we know the values are directly proportional.

This means we can calculate the ratio of people to tons of pollutants and apply it to 500 000

So, 29600/40000= 0.74

Now, 500 000 × 0.74 = 370000

Answer: 370000 t

Step-by-step explanation:

[tex]40000 ~p - 29600 ~ t \\\\ 500000 ~ p- x ~ t \\\\ x=\dfrac{500000\cdot 29600}{40000}=\dfrac{50\cdot 29600}{4} =7400\cdot 50 =\bf 370000 \ t[/tex]

Answers

Answer:

6m-27

Step-by-step explanation:

The equivalent expression of 9(4/3m- 5 - 2/3m + 2) is 6m/3 - 27.

The correct option is C.

What are the equivalent expressions?

Expressions that are equivalent to the same thing, even when they have distinct appearances. When we enter the same value(s) for the variable, two algebraic expressions that are equivalent have the same value (s).

Given;

The expression 9(4/3m- 5 - 2/3m + 2).

To find the equivalent expression:

Simplifying,

9(4/3m- 3 - 2/3m)

= 9(4m/3 - 2m/3 -3)

= 9{(4m-2m)/3 -3}

= 9 {2m/3 - 3}

= 6m/3 - 27.

Therefore, 6m/3 - 27 is the equivalent expression.
