Determine whether the relation is a function. Explain pls
Answers
Answer:
The given relation is not a function.
Step-by-step explanation:
A relation is any set of ordered pairs, which can be thought of as (input, output).
A function is a relation in which no two ordered pairs have the same first component (x-values or input) and different second components (y-values or output).
Given the following relation: {(7, 4), (5, - 1), (3, - 8), (1, - 5), (3, 6)}
There is an input value (x = 3) that has two corresponding outputs (y-values): y = -8 and y = 6.
Remember that a function can only take on one output for each input.
It also helps to do the Vertical Line Test, which allows us to know whether or not a graph is actually a function. If a vertical line intersects the graph in all places at exactly one point, then the relation is a function. To use the vertical-line test, imagine dragging a ruler held vertically across the graph from left to right. If the graph is that of a function, the edge of the ruler would hit the graph only once for every x -value.
Attached is a screenshot of the plotted points on a graph, where I performed the Vertical Line Test. The green line is the vertical line that contains two points that made the relation invalid as a function.

mrs. williams is deciding between two field trips for her class. The science center charges $225 plus $6 per student. The dino discoverry museum simply charges $11 per student. For how many students will the science center charge less than the dino discovery museum?
Answers
Answer:
Step-by-step explanation:
let x = number of students
Science Center will charge total of 135 + 3x
Dino Discovery Museum will charge total of 6x
for what x the Science Center charge less than the Dino Discovery museum that is
135 + 3x < 6x
135 < 6x - 3x
3x > 135
x > 135/3
x > 45
The Science Center charge less than the Dino Discovery museum for more then 45 students.
45students will the science center charge less than the dino discovery museum
What is Algebra?
One of the many branches of mathematics is algebra. Algebra, which is a common thread throughout practically all of mathematics, is broadly defined as the study of mathematical symbols and the rules for manipulating these symbols in formulas.
Suppose x is the number of Students
Total fees for Science Center will be,
135+3x.
Total fees for the Dino Discovery Museum will be 6x.
The Science Center charges a lower price than the Dino Discovery Museum for what x.
135 + 3x < 6x
135 < 6x - 3x
3x > 135
x > 135/3
x > 45
Hence, For classes with more than 45 Students, the Science Center charges less than the Dino Discovery Museum.

[tex]\frac{2}{5}[/tex] and [tex]\frac{2}{7}[/tex]
Step-by-step explanation:
We want to work backwards. Currently we have [tex]\frac{ }{ }[/tex][tex]\frac{?}{?}[/tex] ÷ 5 = [tex]\frac{2}{25}[/tex].
If we multiply both sides by 5, we get [tex]\frac{?}{?}[/tex] = [tex]\frac{2}{25}[/tex] × [tex]\frac{5}{1}[/tex].
We can use multiplication of fractions to solve this. To multiply fractions we multiply the two numerators together and multiply the two denominators together, giving an answer of [tex]\frac{?}{?}[/tex] = [tex]\frac{10}{25}[/tex].
This can be simplified to [tex]\frac{2}{5}[/tex].
We can use the same method on the other equation to get an answer of [tex]\frac{2}{7}[/tex].

When does an equation involving rational expressions have straneous root
Answers
Answer:
Many mathematical operations are reversible, meaning you can go not just from A to B, but by the same reason go from B back to A.
Example x + 4 = 7. Subtract 4 from each side to get x = 7 - 4 = 3. But you could, if you wished, go from x = 3 to x + 4 = 7 by simply doing the opposite, adding 4.
Now consider an operation that is NOT reversible.
Example: Given sqrt(x) = x - 2. Square each side to get x = (x - 2)^2 =x^2 - 4x + 4, or
x^2 - 5x + 4 = 0. Factoring gives (x - 1) (x - 4) = 0. So, IF the original equation holds for a real number x, then the only possibilities are x = 1, x = 4.
If you plug x = 4 back into original equation, you get sqrt(4) = 4 - 2, which is true. But, if you plug in x = 1, you get sqrt(1) = 1 - 2, which is NOT true, as sqrt(1) = 1, not -1. The logic of the derivation was that, IF original equation were true, then x could possibly be only 1 and/or 4. In effect, it was really telling you what x is NOT, namely any number besides 1 and 4. Once you test the two “candidates” you see that one works and the other doesn’t.
Why does this happen? It has to do with the fact that square root is only a principal branch. Just as sqrt(16) is only 4 and not -4, so we are dealing with a limited possibility with which to start. Squaring glosses over this, and when you solve a quadratic equation, it generally gives two solutions (not nec. real). Because sqrt(x) started out to be nonnegative, that created the problem at end.
The graph of a linear function has a slope of 5 and passes through the point (2,5). What
is the y-intercept of the graph of the function?
Answers
Answer:
-5 is the y intercept.
Step-by-step explanation:
Ok, lets do the steps in order.
1) Make a point-slope form equation.
We know that the format of it is y - y1 = slope(x - x1), so we know have to substitute our information in the equation.
y - 5 = 5(x - 2)
2) Convert our point-slope form equation into slope intercept form, and solve for the y-intercept.
y = slope(x) + b... right? So we now have to do math.
Distribute the right side of the equation to get :
y - 5 = 5x - 10
Now cancel out the -5, and then subtract on both sides.
y = 5x - 5
And -5 is your y intercept :)
