Answer:
1. 7
2. 13
Step-by-step explanation:
1. x = 2 and y = 3
y^2 - x
= 3^2 - 2
= 9 - 2
= 7
2. x = 5 and z = 4
z + x + z
= 4 + 5 + 4
= 9 + 4
= 13

Two functions are_______
equivalent if their
graphical representations are the same (always, sometimes, always)
Two functions are always equivalent if their graphical representations are the same.
What is a function?A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
The collection includes all locations on the surface of the shape (x, f(x)) that make up a function of f's graph. We may alternatively say that the graph of f is the curve of y = f. (x). As a result, the diagram of an equation is a particular instance of the graphs of functions.
Two functions are always equivalent if their graphical representations are the same.

A bottle contains 2 liters of water. The bottle leaks 80 milliliters of water every 3 minutes. Will the bottle be empty in an hour
Answer:
No
Step-by-step explanation:
2 liters = 2,000
80/3 = 26.6
the bottle leaks 26.6 milliliters in a min
26.6*60 = 1596
1596 / 1000 = 1.596 (to convert to liters)
the bottle will leak 1.596 an hour

A. x = - 1 2 3 4
B. y = - 1/2 x ²
C. x = 1 / 4²
Do y = x
Answer:
the answer is "B"
the "a" (as in ax^2) is negative thus the parabola "goes downward"
Step-by-step explanation:
The equation of parabola is,
y = - 1/2x²
What is Parabola?A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line, which is known as the directrix.
We have to given that;
In a parabola,
Vertex = (0, 0)
Since, We know that;
Standard form of equation of parabola is,
y = a (x - h)² + k
Where, (h, k) = (0, 0) = vertex
Hence, We get;
y = a (x - 0)² + 0
y = ax²
Here, A point on parabola is, (2, - 2)
- 2 = a (2)²
a = - 2 / 4
a = - 1/2
Hence, The equation of parabola is,
y = - 1/2x²

GL= GR + RL
GL = ( 6x - 3) + (2x+9) = 8x +6
GR = RL
6x - 3 = 2x+9
6x -2x = 9+3
4x = 12 —> x= 12/4 —> x = 3
GR = 6x - 3 = 6(3)-3= 18 -3 =15
RL= 2x+9 = 2(3)+9= 6+9=15
GL = 8x +6 = 8(3)+6=24+6=30
or ; GL= GR + RL = 15+15= 30
