Y would be the output value after inputting an X value and solving the necessary equation.
On the pictured graph, the numbers along the bottom are the X values and the numbers along the side are the Y values.
Looking at where the yellow dots are located on the X axis, there ia a dot at 0, 7, 14, 21, 28 and 35.
Now look at the corresponding Y values for each of those dots, they are at 0, 42, 84, 126, 168 and 210.
To find the proportionality of the graph using the equation y =kx, we can fill in the Y and X values and solve for k.
using x = 7 and Y = 42, the equation becomes 42 =k(7).
To solve for k divide both sides by 7: k = 42/7 = 6
When you replace the x and Y with the other numbers on the graph k is also equal to 6, so the correct equation would be B. y = 6x
Answer:
c. No, for each height, there are people of different ages.
Step-by-step explanation:
We say that y is a function of x when there is a relationship between x and y. For example, the distance you run on a single day and your average speed.
However
There is no relationship between age and height. For example, we may both be the same age and have very different heights.
So the correct answer is:
c. No, for each height, there are people of different ages.
Answer:
y = -3x - 9
Step-by-step explanation:
Parallel lines have same slope.
y = mx + b
m -> slope & b ->y-intercept
y = -3x - 2
So, slope of the required line = -3
(-4 , 3)
y - y1 = m(x - x1)
y - 3 = -3(x - [-4])
y - 3 = -3(x + 4)
y - 3 = x*(-3) + 4*(-3)
y - 3 = -3x - 12
y = -3x -12 + 3
y = -3x - 9
The equation for the red graph will be g(x) = x² + 3.
<h3>What is a function?</h3>
A statement, principle, or policy that creates the link between two variables is known as a function.
The function f(x) is given below.
f(x) = x²
Then the function g(x) will be given as
g(x) = x² + 3
Then the equation for the red graph will be g(x) = x² + 3.
The missing graph is given below.

<h3>
Answer: 3x^3 + 11x^2 - 5x - 25</h3>
Work Shown:
yz = y(x^2+2x-5)
yz = y(x^2) + y(2x) + y(-5)
yz = x^2( y ) + 2x( y ) - 5( y )
yz = x^2( 3x+5 ) + 2x( 3x+5 ) - 5( 3x+5 )
yz = x^2*3x + x^2*5 + 2x*3x + 2x*5 - 5*3x - 5*5
yz = 3x^3 + 5x^2 + 6x^2 + 10x - 15x - 25
yz = 3x^3 + 11x^2 - 5x - 25
