Answer:

C- $750

Step-by-step explanation:

36,000 = 48b

Since the tuition fees for 4 years equals $36,000, you would first need to solve how many months equals 4 years (48). Divide the total sum of the tuition ($36,000) by the number of months the student would have to pay (48) in order to get $750/mo.

We see : 4x - 5y = -20

We can write the negative form of 4x - 5y by switching the signs : - (4x - 5y ) = -4x + 5y

Since -4x + 5y is the negative form of 4x - 5y, the result should also be the opposite : 20

And -4x + 5y is indeed 20, so the answer is infinitely many solutions.

Answer:

infinitely many solutions

Step-by-step explanation:

4x - 5y = - 20 → (1)

- 4x + 5y = 20 → (2)

add (1) and (2) term by term

0 + 0 = 0

0 = 0 ← true statement

this indicates the system has infinitely many solutions

Answer:

The difference between a two step equation and a inequality equation is that two step equation you can isolate the variable and get the answer. However in a inequality equation you can only compare, for example A > 7

Step-by-step explanation:

A inequality compares not giving a clear answer. A two step equation lets you find a clear answer.

Answer:

47%

Step-by-step explanation:

300÷100=3

3=1%

140 is not divisible by 3 so we round it to the nearest multiple of 3 which is 141 this is divisible by 47 making this answer 47%

Step-by-step explanation:

m = (y2 - y1)/(x2 - x1)

= 5 -(-1) / -3-6

= 6/-9

= -2/3

(y - y1) = m(x - x1)

y -(-1) = -2/3(x - 6)

y + 1 = -2/3x + 4

y = -2/3x + 3

Answer:

y=x-9

Step-by-step explanation:

There are 2 parts to finding the equation of a line: the slope and the y-intercept. In the equation y=mx+b, m is the slope and b is the y-intercept.

First, let's find the slope. 2-(-3)=5 and -7-(-2)=-5, so the slope is -5/5=-1.

Now we can plug in one of the given points to the equation to find the y intercept:

y=x+b

-7=2+b

b=-9

Now, we have the slope and the y intercept, so we can write the equation.

y=x-9

I hope I did well enough explaining this. Happy mathing!

Step-by-step explanation:

Ok so the Markup is how much money you will add on the price so it's 15% of $18 and you don't need to add it onto $18

The Retail Price is the entire price so the retail would be the Markup + Price.

15% of $18 is is $2.7 and $18 + $2.7 is $20.7

standard form means that u order each term by highest to lowest degree (degree is like the sum of all the exponents of the variables in a term). [tex]x^5[/tex] is the highest, [tex]9x^4[/tex] is the second highest, [tex]-8x^3[/tex] is the third highest, [tex]-2x^2[/tex] is the fourth highest, [tex]7x[/tex] is the fifth highest, and [tex]-4[/tex] is the lowest because if it has no variable, it's equivalent to [tex]-4x^0[/tex] which is obviously the lowest. hope this helps

The standard deviation will stay the same as it is not affected by a change in a single measurement,

A standard deviation is a measure of how dispersed the data when compared to the mean.

In this case, the standard deviation will stay the same as it is not affected by a change in a single measurement. Therefore, the change will not affect the standard deviation of the set of student ages.

Answer:

y = 18x + 9

Explanation:

(0,9), (1,27)

slope:

[tex]\sf \dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\sf \dfrac{27-9}{1-0}[/tex]

[tex]\sf 18[/tex]

equation:

y - y₁ = m ( x - x₁)

y - 9 = 18 ( x - 0 )

y = 18x + 9

Answer:

y= [tex]\frac{1}{18}[/tex]x + 9

Step-by-step explanation:

(0,9) , (1,27)

([tex]x_{2}[/tex]-[tex]x_{1}[/tex])÷([tex]y_{2}[/tex]-[tex]y_{1}[/tex]) = slope

[tex]x_{2}[/tex]=1    [tex]x_{1}[/tex]=0    [tex]y_{2}[/tex]=27    [tex]y_{1}[/tex]=9

(1-0)÷(27-9) = 1/18

m = slope = 1/18

y- [tex]y_{1}[/tex] = m (x- [tex]x_{1}[/tex])

y-9= [tex]\frac{1}{18}[/tex] (x-0)

y-9 = [tex]\frac{1}{18}[/tex]x

y= [tex]\frac{1}{18}[/tex]x + 9

A. As the population of the beaver represents a certain law along with the year.

B. The point Q labels that 3.5 years after 1995 the amount of beaver has grown up to 475 approximately.

C. According to the question, the population is grown exponentially.

p(t) pass through point ( 1, 100), (2, 200), ( 3, 400), ( 4, 800)

therefore, 200 = 100 x 2 = 100 x 2 ^1 = 100 x 2^ 2-1

400 = 100 x 4 = 100 x 2 ^2 = 100 x 2^ 3-1

800 = 100 x 8 = 100 x 2 ^3 = 100 x 2^ 4-1

Answer = p (t) 100 . 2 ^ t-1

The average conversion energy from producers to primary consumers will be 10%

As we know that energy can not be created nor be destroyed but it can only be transferred from one form to another.

So the primary consumers take energy as food and this energy is utilized in their metabolism and the remaining they transfer.

The average conversion energy from producers to primary consumers is only 10%.
