Which inequality relates BC and XY?

Answer:

17.6 years

Step-by-step explanation:

There are currently 73 million cars in a certain country, decreasing by 1.7% annually.

How many years will it take for this country to have 54 million cars? Round to the

nearest year.

We use the formula

y = a(1 - r)^t

a = Initial amount = 73 million cars

y = Future amount = 54 million cars

r = decreasing rate = 1.7 % = 0.017

t = time is unknown

54,000,000 = 73,000,000(1 - 0.017)^t

Divide both sides by 73,000,000

54,000,000/73,000,000 = (0.983)^t

0.7397260274 = (0.983)^t

Take the logarithm of both sides

log 0.7397260274 = Log (0.983)^t

log 0.7397260274 =t log (0.983)

t = log 0.7397260274/log 0.983

t = -0.13092910029/-0.00744648216

t = 17.5826783005 years

Approximately = t = 17.6 years

Answer:

Because you need it for your later life and for your GCSES and if you dont want to fail then you will need it.

Step-by-step explanation:

Given an exponential equation in which a common base cannot be found, solve for the unknown. Apply the logarithm of both sides of the equation. If one of the terms in the equation has base 10, use the common logarithm. If none of the terms in the equation has base 10, use the natural logarithm.

Step-by-step explanation:

[tex] {4}^{2} - (x + 8)[/tex]

[tex] {4}^{2} - (2 + 8)[/tex]

[tex] {4}^{2} - 10[/tex]

[tex]4 \times 4 - 10[/tex]

[tex]16 - 10[/tex]

[tex] = 6[/tex]

Hello! :)

[tex]\large\boxed{p = -38}[/tex]

4(2p - 8) - 6p = 20 + 4(p + 6)

Distribute the coefficients outside of the parenthesis:

4(2p) + 4(-8) - 6p = 20 + 4(p) + 4(6)

8p - 32 - 6p = 20 + 4p + 24

Combine like terms:

2p - 32 = 44 + 4p

Subtract 2p from both sides:

-32 = 44 + 2p

Subtract 44 from both sides:

-76 = 2p

Divide both sides by 2:

p = -38.

Answer p = -4

6p + 2(4 + -2p) = 3(p + 4)

6p + (4 * 2 + -2p * 2) = 3(p + 4)

6p + (8 + -4p) = 3(p + 4)

8 + 6p + -4p = 3(p + 4)

8 + 2p = 3(p + 4)

8 + 2p = 3(4 + p)

8 + 2p = (4 * 3 + p * 3)

8 + 2p = (12 + 3p)

8 + 2p = 12 + 3p

8 + 2p + -3p = 12 + 3p + -3p

8 + -1p = 12 + 3p + -3p

8 + -1p = 12 + 0

8 + -1p = 12

8 + -8 + -1p = 12  

0 + -1p = 12 + -8

-1p = 12 + -8

-1p = 4

p = -4

Option 3: [tex](x-2)^2+(y-1)^2 = 16[/tex] is the correct answer

Step-by-step explanation:

We will find the equation of the circle with given information and then compare with the choices given.

Given

Center = (h,k) = (2,1)

And point on circle = (2,-3)

The equation of circle is given as:

[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

The distance between center and point on circle is the radius. So using the distance formula:

[tex]r = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\r = \sqrt{(2-2)^2+(-3-1)^2}\\r = \sqrt{(0)^2+(-4)^2}\\r = \sqrt{0+16}\\r = \sqrt{16}\\or\\r = 4[/tex]

Putting the values in equation of circle

[tex](x-2)^2+(y-1)^2 = 4^2\\(x-2)^2+(y-1)^2 = 16[/tex]

Hence,

Option 3: [tex](x-2)^2+(y-1)^2 = 16[/tex] is the correct answer

Answer:

y = 2x - 4 (the slope is 2 or 2/1 and the y-intercept is -4)

Step-by-step explanation:

Subtract 14x from both sides of the equation.

This should get you  -7y = 28 - 14x.

Then you need to divide by -7 on both sides.

y = -4 + 2x is the result

which you can switch around if you like and get y = 2x - 4

Part A: Yes, the data represent a function. The definition of a function is a relation in which no value of x will have two different values of y.

(Every time you plug in 3 as x, you will always get 4 as y; it's ok if you plug in 3 and 5 as x and get the same y, you just can't get two different y's for one x; sorry, it is pretty confusing). None of the numbers in the table repeat, so we can safely say that the relation is a function.

Part B: All we have to do is plug in 11 for x in the function given to find the answer:

In the table, y = 8 when x = 11, but in the function given, y = 34 when x = 11, so the function given is greater.

Part C: To find the answer to C, just plug in 99 for f(x), as it tells you to do:

Answer: X = 2

Answer:

Question 3: y =x+2

Step-by-step explanation:

to find the equation use y=mx+c where m is the gradient/slope and c is the y intercept. In example 3, the y intercept is 2 so thats why the equation ends in +2, and the slope which is calculated by rise over run, is 2 over 2, or 1 so x doesnt need a coefficient.

Explanation:

720/6 = 120

44 x 120 = 5280

Answer:

$5280

Hope this helps!!!!!

Step-by-step explanation:

Cost of 6 notebooks = 720

Then, cost of 1 notebook = 720/6

Therefore, cost of 44 notebooks = 720/6 x 44

= 120 x 44

= 5,280

Therefore, the cost of 44 notebooks will be 5,280
