Answer:

blank=x=84

Step-by-step explanation:

7*3=(3x)/(4*3)

21=3x/12 simplification

252=3x multiply by 12 on both sides

x=84 divide by three

What is the equation for the points (-2,3) (1,9) on a graph

Over [174]

9514 1404 393

Answer:

y -9 = 2(x -1) . . . point-slope form
y = 2x +7 . . . . slope-intercept form
2x -y = -7 . . . . standard form

Step-by-step explanation:

Perhaps you want the equation of the line that goes through these two points.

The slope of the line can be found using the formula ...

m = (y2 -y1)/(x2 -x1)

m = (9 -3)/(1 -(-2)) = 6/3 = 2

We can use one of the points to write the equation in point-slope form:

y -k = m(x -h) . . . . . . . . line with slope m through point (h, k)

For slope 2 and point (1, 9) the equation is ...

y -9 = 2(x -1) . . . . equation in point-slope form

We can eliminate parentheses and get y by itself to put the equation into slope-intercept form.

y -9 = 2x -2

y = 2x +7 . . . . . . equation in slope-intercept form

With a little further rearranging, we can put this into standard form. We can get that by adding -7-y to both sides of the equation.

2x -y = -7 . . . . . equation in standard form

The roots of the quadratic function describing the relationship between number of products produced and overall profit margin ar

kykrilka [37]

Answer:

I assume that we want to complete the statement:

"The maximum profit of $__ dollars is reached when __ items are produced"

We know that the profit equation is defined between x = 0 and x = 100, which are the two roots of the equation (so the profit is equal to zero for x = 0 and for x = 100).

Then we can assume that the profit will be positive in this range.

Thus, the quadratic equation should have a negative leading coefficient, which would mean that the arms of the graph go downwards.

If this is the case, we know that the maximum will be at the vertex.

Here we know that the vertex is:

(50, 1000)

Where remember, x represents the number of items and y represents the profit.

So, given that the maximum is at the vertex, and we know that the vertex is (50, 1000) we can conclude that the maximum profit is $1000, and this happens when the number of produced items is 50.

Then the complete statement is:

"The maximum profit of $1000 dollars is reached when 50 items are produced"
