Can someone please help me with math.

Answer:

[tex]f(x)=600(0.09)^x[/tex]

Step-by-step explanation:

Since f(x) decreases by 9% for every one unit increase in x, it means that f(x) is an exponential decay function. An exponential function is given by:

f(x) = [tex]ab^x[/tex]; where a is the value of f(x) at x = 0, b is the multiplier and is less than 0 for a decay.

Therefore since at x = 0, f(x) = 0. Hence a = 600. Also, b = 9% = 0.09.

The function f(x) can hence be represented as:

[tex]f(x)=600(0.09)^x[/tex]

Answer:

36

Step-by-step explanation:

The sum of the angles of a triangle is 180 degrees

<A+ <B+ <C = 180

2x+6x+2x = 180

10x = 180

Divide by 10

10x/10 = 180/10

x = 18

We want to find <C

<C = 2x

     = 2*18

    = 36

Answer:

9

Step-by-step explanation:

plug -20 into x

-20+3y=7

solve

add 20 to both sides

3y=27

y=9

Answer:

Infinite amount of solutions

Step-by-step explanation:

Step 1: Define Systems

y = -2x + 4

2x + y = 4

Step 2: Solve for x

Substitution

Here we see that 4 does indeed equal 4.

∴ the systems of equations has an infinite amount of solutions.

Step-by-step explanation:

Step 1: Define Systems

y = -2x + 4

2x + y = 4

Step 2: Solve for x

Substitution

Substitute in y:                                                                                                  2x + (-2x + 4) = 4

Combine like terms:                                                                                         4 = 4

Here we see that 4 does indeed equal 4.

∴ the systems of equations has an infinite amount of solutions.

Answer:

35 and 24

Step-by-step explanation:

35 + 24 = 59

35 - 24 = 11

Answer:

24 and 35

Step-by-step explanation:

x + y = 59

x - y = 11,    then x = y + 11

substitute for x:

y + 11 + y = 59

simplify:

2y + 11 = 59

subtract 11 from each side of the equation:

2y = 48

divide both sides by 2:

y = 24

x = 35

f(x) = (cost)x

Answer:

c=s*x

Step-by-step explanation:

C will be the total cost of our family's outing to the soccer game

While x will be the hours

and S will be the soccer game

So s*x will equal the cost

Making c=.

Answer:

linear

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

Since x is squared, that's a non-linear equation because it's the only answer that, when graphed, doesn't form a straight line

Answer:

9,11,16. 4,6,7. 6,8,12

Right. Acute. obtuse

Step-by-step explanation:

obtuse 9,11,16

acute 4,6,7

obtuse 6,8,12

Answer:

Correct

Step-by-step explanation:

To isolate the variable of x, simply add 16 to 11 which is 27 and now it is set up as 4.5x=27 and 27/4.5, it = 6

Answer:

Gray and all are right.

Step-by-step explanation:

4.5x + 16 = 11.5

4.5x = 11.5 - 16

4.5x = -4,5

x = -4.5/4.5

x = -1

4.5x + 27 = -9

4.5x = -9 - 27

4.5x = -36

x = -36/4.5

x = -8

4.5x - 16 = 11

4.5x = 11 + 16

4.5x = 27

x = 27/4.5

x = 6

-4.5x + 27 = 45

-4.5x = 45 - 27

-4.5x = 18

x = 18/-4.5

x = -4

Answer:

No, 16t -3t equals 13t while 3t - 16t equals -13t

Answer:

No,

16t= 16x2=32

3t=3x2=6

32-6=26

3t=3x2=6

16x2=32

6-32=-26

Step-by-step explanation:

t=2?

Answer:

$315

Step-by-step explanation:

You are going to want to use the simple interest formula for this. The one below is modified for solving the interest earned.

I = interest amount

P = principal amount

r = interest rate (decimal form)

t = time

Now we can plug in the values into the equation:

This means that Rachel earned $315 worth of interest in the 15 year period.

Answer:

50%

thats the answer

5 because of slope equation

Answer:

10.3

Step-by-step explanation:

The question is asking to find the length of the hypotenuse of the triangle. This requires us to use the Pythagorean theorem. The legs measure 9 and 5, so we use these to solve for c.

[tex]9^{2} + 5^{2} =c^{2} \\81 + 25 = c^{2} \\106 = c^{2} \\[/tex]                            

We find the square root of both sides to find the value of c.

10.295 ≈ c

Rounded to the nearest tenth, c ≈ 10.3. The answer is 10.3

Answer:

Sample Response: As the number of trials changes, the distribution changes. Since there is a 50% chance of rolling an even number, having a small number of successes is less likely when the number of rolls increases.
