Here, first we need to calculate the slope of the line,
Here, Coordinates = (4, 6) (-1, -4)
m = y2 - y1 / x2-x1
m = 6 + 4 / 4 + 1
m = 10/5
m = 2

Now, Take first coordinate: y - 6 = 2 (x - 4)
Second coordinate: y + 4 = 2 (x + 1)

In short, Your Answers would be Option B & D

Hope this helps!

James spent $(2y2 + 6). He bought notebooks that each cost $(y2 − 1).

CaHeK987 [17]

The expression to find the number of notebooks James bought would be written as:

Number of notebooks = total spent / cost per item

Number of notebooks = (2y^2 + 6) / (y^2 − 1)

If y = 3, then the number of notebooks bought would be:

Number of notebooks = (2y^2 + 6) / (y^2 − 1)
Number of notebooks = (2(3)^2 + 6) / (3^2 − 1)
Number of notebooks = 3 pieces

What is the value of sec theta given the diagram below?

marishachu [46]

Answer:

$\sec \theta=-\sqrt{5}$

Step-by-step explanation:

The hypotenuse is $h^2=6^2+3^2$

$h^2=36+9$

$h^2=45$

$h=\sqrt{45}$

$h=3\sqrt{5}$

The terminal side of $\theta$ is in the second quadrant.

In this quadrant; the secant ratio is negative.

$\sec \theta=-\frac{hypotenuse}{adjacent}$

$\sec \theta=-\frac{3\sqrt{5}}{3}$

$\sec \theta=-\sqrt{5}$

So a department store worker gets paid 325.00 per week plus 4% commission of their total sales if the worker sells 3600 of the m

MAXImum [283]

Answer:The amount of commission made is 144

Step-by-step explanation:

The department store worker gets paid 325.00 per week plus 4% commission of their total sales. This means that the worker's earning is not fixed. It varies with the amount of sales made

if the worker sells 3600 of the merchandise, it means that the worker's sales commission will be 4% of 3600 of the merchandise

Sales commission earned by the store worker = 4/100 × 3600

= 0.04 × 3600 = 144
