<span>To write a two-variable equation, you would first need to know how much Maya’s allowance was. Then, you would need the cost of playing the arcade game and of riding the Ferris wheel. You could let the equation be cost of playing the arcade games plus cost of riding the Ferris wheel equals the total allowance. Your variables would represent the number of times Maya played the arcade game and the number of times she rode the Ferris wheel. With this equation you could solve for how many times she rode the Ferris wheel given the number of times she played the arcade game.</span>
It's C because the equations are similar
Looks like all real numbers except 1. It touch's all the y except 1 aka range
Answer:
.
Step-by-step explanation:
The linear approximation is given by the equation
Linear approximation is a good way to approximate values of 
as long as you stay close to the point 
, but the farther you get from 
, the worse your approximation.
We know that,
Next, we need to plug in the known values and calculate the value of 
:
Then
.
Remember that a parallel line has the same slope...
So we already know the slope of the line containing point C is -4.
Using point slope equation, we can do...
y-y₁=m(x-x₁)
y-7= -4(x-4)
y-7- -4x+16
*Add seven to both sides...* y=-4x+23
There is you answer... hope this helps!
