Answer:
Step-by-step explanation:
I used Desmos a graphing calculator to find it by plotting the points. I then found the "a" in the equation to find the "d". I know this doesn't sound helpful so can someone else please explain better than me???
Answer:
7 donuts at $0.36/donut = $2.49
Step-by-step explanation:
$4.27
------------ = unit cost = $0.36/donut
1 dozen
Then: 7 donuts at $0.36/donut = $2.49
In one hour the plane will cover a distance of 1238 km.

What is a linear equation?</h3>
- A linear equation has one or two variables.
- No variable in a linear equation is raised to a power greater than 1.
- No variable is used as the denominator of a fraction.
- A linear equation is defined as an equation that is written in the form of ax+by=c.
- When solving the system of linear equations, we will get the values of the variable, which is called the solution of a linear equation.
solving this we will get the valve of Y is x is given.
calculation:-
today distance = 9904 km.
total time is taken = 8 hours.
∴total distance covered in one hour = 9904/8
= 1238 km.

The answer is 474 i believe
Answer:
Step-by-step explanation:
The quadratic can be solved in a straightforward way:
This tells you that the solutions are ...
2i or -2i
__
For each root of "a", (x -a) is a factor. Thus the factors of the equation are ...
(x +2i)(x -2i)
