The best predicted value of y for x = 9.9 is y = 83.42.
<h3>What is linear equation if two variables?</h3>
Linear equations with two variables are equations with one, zero, or infinitely numerous solutions where every of a two variables has the highest exponential order of 1.
Some key features regarding linear equation if two variables are-
- The two-variable linear equation has the conventional form ax + by + c = 0, where x and y are the variables.
- These solutions might also be expressed in pairs, such as (x, y).
- A graphical representation of a linear equation system in two variables involves two straight lines that can be intersecting, parallel, or coincident.
Now, according to the question;
The given equation is;
y = 55.8 + 2.79x
Calculate the value of y by substituting the value of x = 9.9.
y = 55.8 + 2.79×9.9
y = 83.42
Therefore, the best predicted value of y for x = 9.9 is 83.42.

Answer:
3 2/3ft²
Step-by-step explanation:
Area of a rectangle = Length × Width
Given
Length = 5 1/2 foot
Width = 2/3foot
Substitute
Area of the rectangle = 5 1/2 × 2/3
Area of the rectangle = 11/2×2/3
Area of the rectangle = 22/6
Area of the rectangle = 11/3
Area of the rectangle = 3 2/3ft²
