A jewlery supply shop buys silver chains from a manufacturer for c dollars each, and then sells the chains at a 57% markup

kirza4 [7]

11. 57% = 0.57

12. retail price = c + (0.57c)

13. retail price = 45 + (0.57 x 45)

retail price = 45 + 25.65

retail price = $70.65

14. 57% was added to the original price of the chain which is $25.65

Find the distance between these points. C(0, 4), T(-6, -3)

beks73 [17]

Answer:

$distance=\sqrt{85} =9.22$

Step-by-step explanation:

We can use the general distance formula between any two points $(x_1,y_1)$ and $(x_2,y_2)$ on the plane given by:

$distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\$

We simply identify $(x_1,y_1)$ with (0, 4) and $(x_2,y_2)$ with (-6, -3) , thus obtaining:

$distance=\sqrt{(-6-0)^2+(-3-4)^2}\\distance=\sqrt{(-6)^2+(-7)^2} \\distance=\sqrt{36+49} \\distance=\sqrt{85} =9.22$

Write a linear function f with the values f(-1)=-3 and f(2)=6.

dusya [7]

Answer:

y = 3x

Step-by-step explanation:

Equation of a Line

Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

$\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

The point-slope form of the equation of a line is:

y - k = m ( x - h )

Where m is the slope and (h,k) is a point through which the line passes.

We are given the following values of the function: f(-1)=-3 and f(2)=6. The points are (-1,-3) and (2,6). The slope is:

$\displaystyle m=\frac{6+3}{2+1}=\frac{9}{3}=3$

Now find the equation of the line using the second point:

y - 6 = 3 ( x - 2 )

Operating:

y - 6 = 3x - 6

Simplifying:

y = 3x
