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

Range:
{5,13,7,4}
the list of ordered pairs is a function.
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
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.

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

Answer:
[tex]x^5+9x^4-8x^3-2x^2+7x-4[/tex]
Step-by-step explanation:
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,
What is a standard deviation?
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.

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

aden’s teacher had 4 boxes of pens that each contained y pens. She took 6 pens out of one of the boxes and told her 17 students to divide the remaining pens equally among themselves. Which expression shows the number of pens each student got?
Answer:
Jaden’s teacher had 4 boxes of pens that each contained y pens.
Number of boxes of pen = 4
Number of pens per box = y
Total number of pens = 4 x y = 4y
She took 6 pens out of one of the boxes told her 17 students to divide the remaining pens equally among themselves.
Total number of pens left = 4y - 6
Number of students = 17
