Which equation matches the graphed line?

A. Y= -2
B. Y= -2x
C. X= 2
D. X= -2

Answer:

x = 8

y = 3

Step-by-step explanation:

11x - 20y = 28

3x + 4y = 36

11x - 20y = 28

11x = 20y + 28

x = [tex]\frac{20}{11}[/tex]y + [tex]\frac{28}{11}[/tex]

3x + 4y = 36

3 ( [tex]\frac{20}{11}[/tex]y + [tex]\frac{28}{11}[/tex] ) + 4y = 36

[tex]\frac{104}{11}[/tex]y = [tex]\frac{312}{11}[/tex]

y = 3

x = [tex]\frac{20}{11}[/tex]y + [tex]\frac{28}{11}[/tex]

x = [tex]\frac{20}{11}[/tex] ( 3 ) + [tex]\frac{28}{11}[/tex]

x = 8

Answer: 0.000008

Step-by-step explanation:

So it says 10 to the -6 power...

10*-10*-10*-10*-10*-10*-10

0.000001

Then you multiply that by 8

0.000008

Answer:

I belive the answer is the first graph.

Step-by-step explanation:

When solving the equation as a function, the answer is -3/2.

0-3 = -2/3x - 4

-3 = -2/3x - 4

-9 = -2x - 12

2x = -12 + 9

2x = -3

Divide for: x = -3/2

Step-by-step explanation: this way, if you multiply it out from this form, you get the answer that you were trying to factor in the first place.

Answer:

x = 10

y = 14

Step-by-step explanation:

Here, we want to get the values of x and y

Since all sides are equal, the internal angle is 60 degrees for each internal angle

Since AC = 14

Then y is also 14 since what we have is an equilateral triangle

Secondly ;

6x = 60

x = 60/6

x = 10

Answer:

x=10

Answer: the train traveled 43km southwards

Step-by-step explanation:

First, let's define.

North as the positive y-axis.

East as the positive x-axis.

And the initial position of the train is (0, 0).

Now, we know that:

"A train first travels east for 20 kilometers."

The new position will be:

(0, 0) + (20km, 0) = (20km , 0)

"Then it turns north and travels for 43 kilometers."

The new position will be:

(20km, 0) + (0, 43km) = (20km, 43km)

"Next it goes west for 20 kilometers."

If East if the positive x-axis, then West is the negative x-axis.

The new position of the train will be:

(20km, 43km) + (-20km, 0) = (0, 43km)

Then it travels south for an unknown number of kilometers, such that the final position is the same as the initial position, then if the train goes X kilometers to the south (and because North is the positive y-axis, South will be the negative y-axis), we have:

(0, 43km) + (0, -X) = (0, 0)

(0, 43km - X) = (0, 0)

Then we must have that:

43km - X = 0

43km = X

This means that the train traveled 43km southwards.

Answer:

52.5

Step-by-step explanation:

You would use the Pythagorean theorem to solve this. Using the formula,

a^2 + b^2 = ^2

You would have an equation of 50^2 + 16^2 = c ^2.

50^2 is 2500, and 16^2 is 256.

There, you have 2500+256 = c^2

add those together, and you have 2756.

Now, you have to find the square root of 2756 (to solve 2756 = c^2)

which leaves you with 52.4976189936 . Rounded to the nearest tenth, you end up with 52.5.

Answer:

Step-by-step explanation:

Let's start by weighing everything but the assignments. We'll get back to them momentarily.

You have 85% on 45% of your grade. That's 38.25

Your final weighs in at 20%. You have.           18

So your total so far is                                        56.25

Now that looks mighty low, but we haven't put in the assignments yet.  

So by the time you are finished you will have done 41 out of 48 assignments and that means you have done (41/48)*100 = 85.41 of the work. On these assignments that you have done, you averaged 65%

So your assignment mark will be 0.65 * 85.41 = 55.52

The weighted average = 0.35

The mark you will get is 0.35 * 55.52 = 19.32

So your final grade will be                      56.25  

Grade                                                        75.57

In Canada (where I live), that would be a solid B. I don't know how things are calculated in the US, but I have done the work properly, I think.

Answers:

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

Explanation:

We have the function f(x) = 15000(0.84)^x. If we plug in x = 0, then we get,

f(x) = 15000(0.84)^x

f(0) = 15000(0.84)^0

f(0) = 15000(1)

f(0) = 15000

In the third step, I used the idea that any nonzero value to the power of 0 is always 1. The rule is x^0 = 1 for any nonzero x.

So that's how we get the initial value of the car. The car started off at $15,000.

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

The growth or decay rate depends entirely on the base of the exponential, which is 0.84; compare it to 1+r and we see that 1+r = 0.84 solves to r = -0.16 which converts to -16%. The negative indicates the value is going down each year. So we have 16% decay or the value is going down 16% per year.

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

The value of x is the number of years. In the first section, x = 0 represented year 0 or the starting year. If x = 1, then one full year has passed by. For x = 2, we have two full years pass by, and so on.

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

The value of f(x) is the value of the car after x years have gone by. We found that f(x) = 15000 when x = 0. In other words, at the start the car is worth $15,000. Plugging in other x values leads to other f(x) values. For example, if x = 2, then you should find that f(x) = 10584. This means the car is worth $10,584 after two years.
