Answer:
Yes.
Step-by-step explanation:
First, draw a vertical line. Then check the interception between the graph and a vertical line.
If the line intercepts the graph only one point, then it is a function. Otherwise, it is not. That includes two or more.
The graph shown in the picture is a function (Cubic Function).

What is algebra?Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols.
Given:
[tex]9^{-1/2} = 27^{1/4}[/tex]÷[tex]3^{x +1}[/tex]
[tex][3^{2}]^{{-1/2}} = [(3)^{4}]^{1/4}[/tex] ÷[tex]3^{x +1}[/tex]
[tex]3^{-1}[/tex] = 3 ÷[tex]3^{x +1}[/tex]
[tex]3^{-1}[/tex]= [tex]\frac{3}{3^{x+1}}[/tex]
[tex]3^{-1}= 3^{1-x+1}[/tex]
[tex]3^{-1}= 3^{2-x}[/tex]
On comparing we get,
-1=2-x
x= 3
Hence, the value of x is 3.

If x=3 and y = ─ 4 , find i) (x─y) ─ y ii) ( x+y) +x 2. Write two pairs of numbers satisfying the equation xꓥ2 + yꓥ2 = 25
Answers
Answer:
i) (x -y) -y = 11
ii) (x+y) + x² = 8
iii) The two pairs (( 3 , -4)) and ( ( 3 ,4) satisfy the equation x² + y² = 25
Step-by-step explanation:
Step(i):-
Given that x =3 and y=-4
i) (x -y) -y = (3-(-4))-(-4) = 3+4+4 = 11
ii) (x+y) + x² = ( 3 -4) + (3)² = -1 + 9 = 8
Step(ii):-
Given equation
x² + y² = 25
we can choose (x,y) = ( 3 , -4)
3²+(-4)² = 25
25 = 25
The ordered pair ( 3,-4) satisfies the equation
second ordered pair ( 3 ,4)
x² + y² = 25
9 + 16 = 25
25 = 25
Final answer:-
i) (x -y) -y = 11
ii) (x+y) + x² = 8
iii) The two pairs (( 3 , -4)) and ( ( 3 ,4) satisfy the equation x² + y² = 25

You purchase a video game system for $150. You make a down payment of $25. You pay the rest of the money you owe in 5 equal monthly payments with no interest. How much is each monthly payment ?
Can you help me set the problem up too? thx
Answers
9514 1404 393
Answer:
$25
Step-by-step explanation:
Let p represent the monthly payment. There are 5 of them, so the amount of their total is 5p. That, together with the down payment, makes up the entire cost of the system.
5p +25 = 150 . . . . an equation representing the relationships
__
To solve this, subtract 25 and divide by 5.
5p = 125
p = 125/5 = 25
Each monthly payment is $25.
You set up a hot chocolate stand at a football game. The cost of your supplies is $75. You charge $0.50 for each cup of hot chocolate. Write a function that represents the profit P for selling c cups of hot chocolate.
Answers
Answer:
P = 0.5c - 75
Step-by-step explanation:
Profit is = selling price. - cost price
Cost price is the amount the supplies were bought = $75
The cost of c cups at $0.5 per cup will be
0.5 * c = $0.5c
The profit here is thus;
P = 0.5c - 75

y= x squared +2x - 2
Answers
Answer:
There are no simple factors to this expression. You can however solve for x, giving you:
x = -1 ± √(y + 3)
Step-by-step explanation:
There is no simple pair of factors to this equation, so we'll have to go through the full process. You can see that by observing that there is no pair of rational numbers that add to make 2 and multiply to make -2. We can however solve for x:
[tex]y = x^2 + 2x - 2\\y + 2 = x^2 + 2x\\y + 3 = x^2 + 2x + 1\\y + 3 = (x + 1)^2\\(x + 1)^2 = y + 3\\x + 1 = \pm \sqrt{y + 3}\\x = -1 \pm \sqrt{y + 3}[/tex]
