Answer:
(2, 8) and (3, 11) --- > For example
Step-by-step explanation:
Plug in any number for x
I will use 2.
So if the equation is y = 3x + 2, then the new equation will be ...
y = 3(2) + 2
y = 6 + 2
y = 8 ----> One coordinate can be (2, 8)
Another number you could use is 3.
y = 3(3) + 2
y = 9 + 2
y = 11 ----> Another coordinate may be (3, 11)

put the following equation of a line into slope-intercept form, simplifying all fractions 16x - 4y = -20
Answer:
y = 4x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
16x - 4y = - 20 ( subtract 16x from both sides )
- 4y = - 16x - 20 ( divide terms by - 4 )
y = 4x + 5 ← in slope- intercept form
The equation of a line into slope-intercept form is [tex]y = 4x + 5[/tex].
What is the slope of line?
The slope of a line gives the measure of its steepness and direction.
The slope of a straight line between two points says [tex](x_1,y_1),(x_2,y_2)[/tex] and (x2,y2) can be easily determined by finding the difference between the coordinates of the points. The slope is usually represented by the letter ‘[tex]m[/tex]’.
As we know that, the equation of a line in slope- intercept form is
[tex]y = mx + c[/tex]
where [tex]m[/tex] is the slope and [tex]c[/tex] is the y-intercept.
So,
[tex]16x - 4y = - 20\\\\-4y=-20-16x\\\\-4y=-(16x+20)\\\\4y=16x+20\\\\y=\frac{16x}{4}+\frac{20}{4}\\\\y=4x+5[/tex]
Hence, the equation of a line into slope-intercept form is [tex]y = 4x + 5[/tex].

Ms. Ponse knows that only 44% of the pencils she
leis students borrow will be returned to her. She will
let students borrow 125 pencils in the second
semester. How many pencils can Ms. Ponse plan on
getting back?
Answer:
55
Step-by-step explanation:
44% * 125 = 0.44 * 125 = 55
Answer:
She can expect to receive back 0.44(125 pencils) = 55 pencils
Step-by-step explanation:
She loans out 125 pencils. If 44% will likely be returned, then 100% - 44%, or 56%, will not be returned.
She can expect to receive back 0.44(125 pencils) = 55 pencils
An angle measures 56° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
118, 62
Step-by-step explanation:
We can set a system of equations where x and y are the two angles and x is the larger one
x+y=180
x-y=56
If we subtract the second equation from the first, we get 2y=124, simplifying that, we get y=62. Plugging it into either equation, we get x=118. We can check that 118 is 56 larger than 62, which it is. Thus, x=118, y=62.

The scatter plot shows the average movie ticket prices since 1995.
write an equation in slope intercept form for the line that is drawn
use your equation to make a conjecture about the average cost of a movie ticket in 2020
Answer:
The average movie ticket prices in 2020 was $ 10.25.
Step-by-step explanation:
If (0 , 4) and ( 8, 6) are two points on a line, the slope of the line is:
m= y2 - y1/ x2 - x1
m= (6 - 4) / (8 - 0)
m= 1 / 4
The y-intercept is $ 4, meaning it is the average movie ticket price in 1995.
Therefore,
Y = mx + b
Y = 1/4 x + b
It is m= 1/4, interpreting the slope we have that for every additional 4 years the average movie ticket price will increase by $ 1.
The year 2020 is 25 years after 1995, then
Y= 1/4 (25) + 4
Y = $ 10.25
The average movie ticket price was $10.25 in 2020.

If f(x) = 3x2 – 4 and g(x) = 2x – 6, what is g(f(2))?
O-16
o -2
O 8
0 10
Answer:
The last option, 10 is correct
Step-by-step explanation:
f(x) = 3x^2 - 4
f(2) = 3(2)^2 - 4
f(2) = 12 - 4
f(2) = 8
g(x) = 2x - 6
g(8) = 2(8) - 6
g(8) = 16 - 6
g(8) = 10
This means that g(f(2)) is equal to 10

Sameer scored better than 78% of all students taking a standardized exam. If 650 students took the exam, how many did Sameer score better than?
The interest added at the end of the year is $10, The total goal of O’Neill Raiders fundraiser is $2500 and Sameer scored better than 507 students.
What is Percentage?Percentage is the parts of a number per fraction of 100. We can divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.
Initial amount, P = $250
Rate of interest, r = 4% = 0.04
Interest amount = P × r × t, where t is the number of years = 1 here.
= 250 × 0.04 × 1
= $10
28% of the total fundraising goal = $700
Let x be the total fundraising goal.
28% × x = 700
0.28x = 700
x = 700 / 0.28 = $2500
Total number of students = 650
Sameer scored better than 78% of all students.
Number of students that Sameer scored better = 78% × 650
= 0.78 × 650
= 507
Hence all the answers are found.
