Use properties of exponents to solve for a and b in the problem below. No calculator allowed. Please help; I don't know what I'm doing.

Answer:

Original = $200

Step-by-step explanation:

Original = x

Final = 172

Percent Decrease = 14%

Original = 100%

Final = 100% - 14%

172 = 86%

Solve:

172/86 * 100 = x

2 * 100 = 200

Original = 200

-Chetan K

$ 200 ( approximately )

Step-by-step explanation:

100% - 14% = 86%

100/86 × 172

Answer:

b= 47°

Step-by-step explanation:

the value of a straight line is 180°. so create an equation that sets the angle values to equal 180°, then solve for b:

(3b-6)+(b-2)=180

3b-6+b-2=180

4b-8=180

4b=188

b=47

Answer:

The answer is 3x^2+2x+5

Step-by-step explanation:

I just simply factored and followed the long division method.

The corresponding roots of the quadratic equations are given.

Quadratic expressions are polynomial equations of second degree.

The general form of a quadratic equation is ax² + b x + c = 0.

1. x² = 49

Find the square root.

x = ±√49 = ±7

2. x² - 27 = 0

x² = 27 = 9 × 3

x = √27 = √(9×3) = √9 × √3 = ±3√3

3. 3x² - 36 = 0

3x² = 36

Divide 3 on both sides.

x² = 12

x = √12 = √(4 × 3) = ±2√3

4. 9x² = 0

x = 0

5. 5x² - 15 = 0

5x² = 15

x² = 3

x = ±√3

6. 2x² - 144 = 0

2x² = 144

x² = 72

x = √72 = √(36 × 2) = ±6√2

7. (x + 3)² = 9

x + 3 = √9

x + 3 = ±3

x = 3 - 3 = 0 and x = -3 - 3 = -6

8. 4x² - 100 = 0

4x² = 100

x² = 25

x = ±√5

9. 5x² = 40

x² = 8

x = √8 = √(4 × 2) = ±2√2

10. 3x² - 12 = 0

3x² = 12

x² = 4

x = ±2

11. (x - 5)² = 121

x - 5 = √121

x - 5 = ±11

x = 11 + 5 = 16 or x = -11 + 5 = -6

Hence the solutions are found.

Answer:

  x=1

Step-by-step explanation:

The function f(x) is undefined where its denominator (x+1) is zero. That will be the case for x=-1.

The composition f(g(x)) will give f(x) an argument of -1 when g(x) = -1. That will be the case when ...

Answer:

1/7 km long

Step-by-step explanation:

The area of a square is any given one of the sides, squared. We can take this information and apply it to this problem. If the area is 1/49 km squared, we can take the square root of this to find the length of each side.

The square root of 1 is 1, and the square root of 49 is 7, so the answer is 1/7 km for each side.

Answer:

domain - (-infinity,infinity)

range - (-infinity, 2]

axis of sym - x=-1

y int - (0,-1)

at what value (row 1) - (-1,2)

Step-by-step explanation:

domain is side to side, it never ends bc of the arrows

range is top to bottom, there is no bottom bc of the arrow, but it has a top at 2 (the value on the y axis)

the axis of sym is basically the line that runs through the vertex, it's where you could fold it in half and it would still match up

Answer: 36 cm^2

Step-by-step explanation:

Hello!

We can start by finding the cube root of 216, which is 6. This is the length of each side of the cube.

Now, the area of the base of the cube is equal to 6^2=36 cm^2.

Step-by-step explanation:

Given : Kishore bought a basket containing 30 oranges for rs 310. If he sells the oranges at rs 12 each , what Would be it's profit or loss?

Solution :

Cost price of oranges = rs.310

As we know that each oranges cost rs.12

So, selling price of oranges is 30 × 12 = rs.360

Now, finding profit or loss

Profit = Selling Price - Cost Price

Profit = rs.360 - rs.310

Profit = rs.50

Answer:

0.75

Step-by-step explanation:

1. To change 3/4 into a decimal, you have to divide 3 by 4.

2. (Check out the image below to see how to divide 3 by 4.)

Answer:

3/4 is expressed as 0.75 in the decimal form.

Step-by-step explanation:

Fractions and decimals are two ways to represent the same numbers. A decimal number can be defined as a number whose whole number part and fractional part is separated by a decimal point. A fraction is represented as a numerical value that is defined as a part of a whole.

To convert any fraction to decimal form, we just need to divide the numerator by the denominator.

Here the fraction is 3/4 which means we need to divide: 3 ÷ 4.

* Use the attatched images for steps*

Therefore, 3/4 = 0.75.

Thus, 3/4 is expressed as 0.75 in the decimal form.

Answer:

r = 9

Step-by-step explanation:

r/3 - 6 = -6

First, you need to add 6 on both sides to isolate r/3:

r/3 = 3

Then, you need to multiply both sides by 3 to get r alone:

r = 9

r is 9
