What is the y-intercept, b, of the additive relationship represented by this table? Enter your answer as an integer in the box.

b =
x y
1 4
3 6

Step-by-step explanation:

Use the table to find the slope and y-intercept

Find the slope:

Find b using the pair (1, 4):

The line is:

The y-intercept is 3

b = 3

Step-by-step explanation:

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
