PLZ HELP ASAP!! 16 points!! What are the domain and range of the function graphed below?
Answer:
B. Domain: {-∞ < x < ∞}; Range: {y ≤ 2}
Step-by-step explanation:
In simple terms, the domain of a graphed function refers to all the possible x-values while the range refers to all the possible y-values. Therefore, based on the graph the answer would be.
B. Domain: {-∞ < x < ∞}; Range: {y ≤ 2}
This is because x is in a slope and extends infinitely both to the left and to the right, therefore having all possible values. The y-axis starts at and includes the value 2 and all values less than 2. A black filled in dot in a graph indicates that the value is included.
Genesis has a points card for a movie theater.
• She receives 70 rewards points just for signing up.
• She earns 12.5 points for each visit to the movie theater.
• She needs at least 155 points for a free movie ticket.
Write and solve an inequality which can be used to determine v, the number of visits
Genesis can make to earn her first free movie ticket.
'v' visits.... would get her 12.5v points
She needs at least 155 points... Meaning the least she needs is 155. Also meaning she needs 155 or More...
We would represent that with a "Greater than or Equal to Sign ≥"
12.5v + 70 ≥ 155
12.5v≥155-70
v= 85/12.5
v=6.8.
Our answer can't be in decimal. She can't make 6.8 visits... Rather
The answer would be 7 Visits.
She needs a Minimum of 7visits.
The inequality that can be used to represent the number of visits is
12.5v + 70 ≥ 155.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
Given, Genesis has a points card for a movie theater.
Assuming no. of visits to the movie theater to be 'v'.
∴ An inequality that can be used to determine v, the number of visits
Genesis can make to earn her first free movie ticket as she needs 155 points and already has 70 points is,
12.5v + 70 ≥ 155 we have chosen greater than or equal to as she needs at least 155 points.
12.5v + 70 ≥ 155.
12.5v ≥ 85.
v ≥ 85/12.5.
v ≥ 6.8 but she needs to visit at least 7 times.

4x + 4y = -8
-2x - 2y = 4
Answer: To solve this system of equations, you can use the substitution method.
First, you can solve one of the equations for one of the variables in terms of the other. For example, you can solve the first equation for y:
y = (-4x - 8)/4
Then, you can substitute this expression for y into the second equation to find the value of x:
-2x - 2((-4x - 8)/4) = 4
-2x + 4x + 8 = 4
2x = -4
x = -2
You can then substitute this value of x back into the first equation to find the value of y:
y = (-4(-2) - 8)/4 = (8 - 8)/4 = 0
Thus, the solution to the system of equations is x = -2 and y = 0.
Step-by-step explanation:
If a1 = 7 and an = An-1 – 3 then find the value of a4.
Answer:
-2
Step-by-step explanation:
If a1 = 7 and an = An-1 – 3
a4 = a3 - 3
Get a2;
a2 = a1 - 3
a2 = 7 - 3
a2 = 4
Get a3;
a3 = a2 - 3
a3 = 4 - 3
a3 = 1
GEt the required a4
a4 = a3 - 3
a4 = 1 - 3
a4 = -2
Hence the value of a4 is -2
becky is doing research in which she needs 28 g of a substance that is 30% protein how many grams of each two ingredients one that is 50% protein in the other 25% protein should she mix together
Therefore, Becky must combine 25.6 grams of the second ingredient (25 percentage protein) with 2.4 grams of the first ingredient (50 percent protein) to create 28 grams of
Define percentage.A percentage (%) is a number that can alternatively be written as a decimal or fraction and represents a quantity as a proportion of 100. You can change a percentage to a fraction by putting 100 in the numerator and also the percentage number in the numerator.
Here,
Becky will need to blend several substances to obtain the necessary level of protein in order to generate 28 grams of a material that is 30% protein.
Let's name the first ingredient's percentage of protein (50%) "x" and the second ingredient's percentage of protein (25%) "y".
That which we are aware of is
28 grams of the combination are present in total.
It has 30% protein.
50% of the first component is protein.
25% protein makes up the second component.
To express the issue, we can build up the following equations:
x + y = 28 (the total amount of the mixture is 28 grams) (the total amount of the mixture is 28 grams)
(0.50)x + (0.25)y = 0.30(28) (the mixture is 30% protein)
Now we can use the first equation to solve for one variable in terms of the other. If we solve for y, we get:
y = 28 - x
We can substitute this into the second equation:
(0.50)x + (0.25)y = 0.30(28) (28) (30% of the mixture is protein)
We may now solve for one variable in terms of the other using the first equation. If we figure out y, we obtain:
y = 28 - x
This can be used as a substitution in the second equation:
(0.50)x + (0.25)(28-x) = 0.30(28) (28)
which results in:
0.50x + 7 - 0.25x = 8.4
And simplifying even more
0.25x = 0.6
x = 2.4
We now know that 2.4 grams of the combination are made up of the first component, which is 50% protein. Using this knowledge, we can calculate the quantity of the second ingredient:
y=28 - x=28 - 2.4=25.6 grams

So the solution to the system of equations is:
c = 4, d = 1
What is equation?The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, separated by the 'equal' sign.
Define quadratic equation.x ax2 + bx + c = 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. a 0. It has at least one solution since it is a second-order polynomial equation, which is guaranteed by the algebraic basic theorem.
Given equation I is [tex]3c+6d=18[/tex] and equation II is [tex]6c-2d=22[/tex]
We can start by multiplying the first equation by -2 and adding it to the second equation. This will eliminate the d variable:

Using the Pythagoras Theorem the value of c=11.40 and the number that goes beneath the radical is 130.
What is Pythagoras Theorem?
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side.
The rectangle is divided into two triangles which have exactly same sides.
So take any one triangle.
Apply the Pythagoras theorem since it is a right-angled triangle with base = 9 and perpendicular = 7.
So, according to Pythagoras theorem -
(Hypotenuse)^2=(Base)^2+(Perpendicular)^2
Plugging in the values in the equation -
c^2=(9)^2+(7)^2
c^2=81+49
c^2=130
c=[tex]\sqrt{130}[/tex]
c=11.40

A bag contains 10 pieces of paper, numbered 1 through 10with a different number on each piece of paper. A second bag contains 8 pieces of paper, numbered 20 through 27with different number on each piece of paper. One piece of paper is drawn random from each bag. What is the expected value of the sum of the numbers on the two selected pieces of paper
To find the expected value of the sum of the numbers on the two selected pieces of paper, we need to calculate the probability of each possible outcome and then multiply that probability by the value of the outcome. The expected value of the sum of the numbers on the two selected pieces of paper is 6.1625.
Therefore the answer is 6.1625.
The possible outcomes for the first bag are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, each with a probability of 1/10.
The possible outcomes for the second bag are 20, 21, 22, 23, 24, 25, 26, 27, each with a probability of 1/8.
The possible outcomes for the sum of the numbers on the two selected pieces of paper are:
(1,20) ,(1,21) ,(1,22) ,(1,23) ,(1,24) ,(1,25) ,(1,26) ,(1,27)
(2,20) ,(2,21) ,(2,22) ,(2,23) ,(2,24) ,(2,25) ,(2,26) ,(2,27)
(3,20) ,(3,21) ,(3,22) ,(3,23) ,(3,24) ,(3,25) ,(3,26) ,(3,27)

(10,20) ,(10,21) ,(10,22) ,(10,23) ,(10,24) ,(10,25) ,(10,26) ,(10,27)
The expected value of the sum of the numbers on the two selected pieces of paper is the sum of the products of each possible outcome and its corresponding probability.
The probability of each outcome is (1/10) * (1/8) = 1/80
So the expected value of the sum of the numbers on the two selected pieces of paper is
(1 + 21)×(1/80) + (1 + 22)×(1/80) + (1 + 23)×(1/80) + (1 + 24)×(1/80) + .... + (10 + 27)×(1/80) = (21 + 22 + 23 + 24 + ... + 37)/80
= (20×17 + 1 + 2 + ... + 17)/80
= (340 + 17×(17 + 1)/ 2)/ 80
= (340 + 17×9)/ 80
= 6.1625
