What is the slope of the line that passes through the points (2,3) and (-2,6)?

Kobotan [32]

Answer:

-3/4

Step-by-step explanation:

To find the slope of the line, use the slope formula:

$m = \frac{y_2-y_1}{x_2-x_1} = \frac{6-3}{-2-2} =\frac{3}{-2+-2}=\frac{3}{-4}$

The slope of the line is -3/4.

A company sells widgets. The amount of profit y made by the company is related to the selling price of each widgets x by the giv

SCORPION-xisa [38]

Answer:

The maximum amount of profit is 32

Step-by-step explanation:

Given

$y=-x^2+64x-292$

Required

Determine the maximum profit

This is calculated by calculating the maximum of the function.

A quadratic function is of the form

$y = ax^2 + bx + c$

and its maximum is:

$Max = \frac{-b}{2a}$

So: $y=-x^2+64x-292$

We have that

$a = -1$

$b = 64$

$c = -292$

$Max = \frac{-b}{2a}$

$Max = \frac{-64}{2 * -1}$

$Max = \frac{-64}{-2}$

$Max = 32$

<em>Hence, the maximum amount of profit is 32</em>

Miguel has at least $250 in his savings account. Which inequality represents this situation? A. m < 250, B. m > 250, C. m

Bess [88]

At least would indicate that Miguel’s amount is greater than or equal to. At least indicates an amount equal to but also larger than the quantity specified. If it were at most, then we would use less than or equal to. Therefore, choose the one with greater than or equal to 250.
