Answer: I am going tot give you an example for this because I don’t like giving straight up answers ok?
Step-by-step explanation:
Lets use this conversion factor:
4 inches = 1 year
Let's find the year at 5 feet (60 inches) using the conversion factor. Set up a proportion.
4 / 60 = 1 / x
Cross multiply.
4x = 60
x = 15
At 15 years, the height is 60 inches.
We can use these as points.
x = time in years
y = height in inches
Point 1 = (1, 4)
Point 2 = (15, 60)
By looking at the points, we know that as the x values increase, so does the y values. Now the relation between the x and y values of each point is that y is 4 times as that of x. Therefore, we can establish an equation.
y = 4x
This will be the model to use to find the height in 30 years.
......you wasted
points for that
Seven less than the quotient of a number and 12 is 4 and 3.
Answer: -8x^3y^2 (choice B)
The coefficients multiply to 4 times -2 = -8
the x terms multiply to x^2 times x = x^(2+1) = x^3
The y terms multiply to y times y = y^(1+1) = y^2
So that's how I ended up with -8x^3y^2
