1), At Texas A&M University, tuition and fees for 4 years cost approximately $36,000. If a student could pay for these college expenses by the month, the student's monthly school bill would be about- A $650 B $700 C $750 D $900
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.

Write a linear function through the points (0,9) and (1,27)
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

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

The average conversion energy from producers to primary consumers will be 10%
What will be the energy transfer from producers to primary consumers?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%.
This percentage actually holds true for all transfer of energy at any trophic level in the food chain.

r = 3, -3.
Write the equation of the line that goes through the points (-3,5) and (6,-1).
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
What is an equation of the line that passes through the points (-3, -2) and (2, -7)
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
