5. What is the range of the function y = 2x – 4?
Answer:
The domain is how far left and right it goes on a graph, and the range is how far up and down it goes on a graph. Because this equation is linear (if you graphed it, it would be in a straight line), both the domain and range are infinity, because it keeps going up and to the right, the larger X gets, and smaller and to the left, the more negative X gets.
graph is linear:
y=2x-4
solve for x=o
y=2x0-4 Eliminate 0
y=-4 solved for y
solve for y=0
0=2x-4 add 4
+4 +4
4=2x divide by 2
/2 /2
4/2 =x
2=x solved for x
calculate the slope
Solve for x=1
y=2x1-4
y=2-4
y=2 solved for y
Calculating the slope
y -y
a= x=1 x=0 =2
1
The graph is
(0, -4) (2, 0)

The total fees for the high school play are
$250. Tickets to the play cost S5 for
students and S8 for nonstudents. Write a
linear inequality that describes the number
of student and nonstudent tickets that nccd
to be sold for the drama class to be able to
pay the fees.
Answer:
250[tex]\leq[/tex]5s+8ns
Step-by-step explanation:
the total fees are $250, meaning they would still be able to make the fees if they'd oversell the tickets.
each tickets is $5 for students; hence the s
each tickets is $8 for nonstudents; hence the ns
you may replace the variable with anything you'd like or what fits the direction.
The inequality describes the number of student and non student tickets that to be sold for the drama class to be able to pay the fees will be 5x+8y≥250
What is inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given that, The total fees for the high school play are $250. Tickets to the play cost $5 for students and $8 for non students.
Let the cost of students be x and that of non student's be y.
According to question,
5x+8y≥ 250
Hence, The inequality describes the number of student and non student tickets that to be sold for the drama class to be able to pay the fees will be 5x+8y≥250

Solve each equation. Show or explain your reasoning.
−3x − 5 = 16
−4(y − 2) = 12
Answer:
Step-by-step explanation:
First equation: −3x − 5 = 16
Combine the constants:
-3x = 21
Solve for x using division: x = 21/(-3) or x = -7
Second equation: −4(y − 2) = 12
Reduce this by dividing both sides by -4: y - 2 = -3
Add 2 to both sides, to isolate y: y = -1

The school store sells markers for $0.35 each and pencils for $0.15
each. Anthony spent $2.80 to buy a total of 12 markers and pencils. How
many markers did Anthony buy?
PLEASE HELP !
Answer:
x = 5 pens
y = 7 pencils
Step-by-step explanation:
let
x = the number of pens
y = the number of pencils
Anthony spent $2.80 to buy a total of 12 pens and pencils
0.35x + 0.15y = 2.80
x + y = 12
by solving the system of equations
0.35x + 0.15y = 2.80
x + y = 12
we find
x = 5 pens
y = 7 pencils
. 6x – 3y = 15
4x + 3y = -5

Helpppppp it’s for a test I have 2 more questions
Answer:
x = 1. y = -3
Step-by-step explanation:
Add the two equations together and notice that all terms containing y will disappear, leaving with
10x = 10 or x = 1
Using this value of x into either one of the equations, you'll get
4(1) + 3y = -5 ---> 3y = -9 or y = -3

Median = 3500
Step-by-step explanation:
Data Set: 1850, 3500, 4200, 2310, 4260
=> Let's set this to the ascending order (least to greatest) first:
1850, 2310, 3500, 4200, 4260
=> Now as you cancel out the first value, cancel out the last one, and do this until u reach down to only one number:
So our median = 3500

The probabilty that a student owns a car is 0.65 the porbability that a student owns a compuer is 0.82 the probability that a student owns both is 0.55what is the probability that a student owns both and what is the probability that a student owns none
Question: The probability that s student owns a car is 0.65, and the probability that a student owns a computer is 0.82.
a. If the probability that a student owns both is 0.55, what is the probability that a randomly selected student owns a car or computer?
b. What is the probability that a randomly selected student does not own a car or computer?
Answer:
(a) 0.92
(b) 0.08
Step-by-step explanation:
(a)
Applying
Pr(A or B) = Pr(A) + Pr(B) – Pr(A and B)................. Equation 1
Where A represent Car, B represent Computer.
From the question,
Pr(A) = 0.65, Pr(B) = 0.82, Pr(A and B) = 0.55
Substitute these values into equation 1
Pr(A or B) = 0.65+0.82-0.55
Pr(A or B) = 1.47-0.55
Pr(A or B) = 0.92.
Hence the probability that a student selected randomly owns a house or a car is 0.92
(b)
Applying
Pr(A or B) = 1 – Pr(not-A and not-B)
Pr(not-A and not-B) = 1-Pr(A or B) ..................... Equation 2
Given: Pr(A or B) = 0.92
Substitute these value into equation 2
Pr(not-A and not-B) = 1-0.92
Pr(not-A and not-B) = 0.08
Hence the probability that a student selected randomly does not own a car or a computer is 0.08

Answer:
Step-by-step explanation:
The formula for finding the total measure of all interior angles in a polygon is: (n – 2) x 180. In this case, n is the number of sides the polygon has. Some common polygon total angle measures are as follows: The angles in a triangle (a 3-sided polygon) total 180 degrees.
which number sentence states that n is at LEAST 20?
Answer:
D
Step-by-step explanation:
that symbol means greater or equal to. so at LEAST it’s 20. but it could be more
Answer: D
it is saying it is equal to or greater than 20
A car drives 215 km east and then 45 km north. What is the magnitude of the car's displacement? Round your answer to the nearest whole number. km
Answer:
220 km
Step-by-step explanation:
Since the direction north is perpendicular to the direction east, the driver has covered the two legs of a right triangle. The hypotenuse is his displacement for the combination of the two segments.
D = √(215² + 45²)
= √(46,225 + 2,025)
= √48,250 = 219.6588... km

Identify the perimeter show work
Answer:
60
Step-by-step explanation:
The perimeter is the measurement around an object.
So first you multiply the 20 and the 10 by 2.
20 * 2 = 40
10 * 2 = 20
Then, add then up!
40 + 20 = 60
Answer: 60
Step-by-step explanation:
10+10= 20 (both sides)
20+20=40 (other sides)
40+20=60 (total sides)
In the triangle ABC
are drawn two sides
of it, BB1 and AA1.
Those half-edges
intersect at point O.
What is the length of
the semicircular BB1
if B10 = a cm?
Answer:
3a
Step-by-step explanation:
What we have as the point O refers to the centroid of the triangle
The centroid splits the distance between the opposite vertex and the middle of the side length that faces it into two; with the longer side being twice the length of the shorter
So what we have here is that;
B1O is half the length of BO
So, if B1O is a cm, BO would be 2a
So we have the entire side length measure as;
a + 2a = 3a
