The first equation in the following system gives the company's cost of making x purses. The second equation gives the company's

income for selling x purses.
y = negative 0.01 (x minus 500) squared + 4,489. y = 20 x

You used substitution to obtain the equation

0 = -0.01x2-10x+1,989 from the system.

What are the solutions to the system of equations?

(-23,400, 3,400) and (-1,170,170)

(-1,170, -23,400) and (170, 3,400)

The figure below shows a shaded rectangular region inside a large rectangle:
pshichka [43]

Answer:

b. 58%

Step-by-step explanation:

Calculate the area of the entire rectangle using the formula A = lw.

The lowercase "L" is for length.

"w" is for width.

The lighter square is 10 units long by 5 inches wide.

A = lw

A = (10 in)(5 in)   Multiply

A = 50 in²

Calculate the area for the shaded rectangle, 7 inches by 3 inches.

A = lw

A = (7 in)(3 in)    Multiply

A = 21 in²

Calculate the area for the non-shaded region by subtracting the shaded area from the total area.

50 in² - 21 in² = 29 in²

The chance that a point in the large rectangle will NOT be in the shaded region is 29/50.

Convert this fraction to decimal form by using a calculator. Divide the top number by the bottom number.

29/50 = 0.58

0.58 is in decimal form. To convert it to a percentage, multiply the number by 100.

0.58 = 58%

Therefore the probability that a point chosen inside the large rectangle is not in the shaded region is 58%.

If a is (-8, 3) and c is (12, -4), find b if it is 2/5 the distance from a to c
ohaa [14]

Answer:

  (0, 1/5)

Step-by-step explanation:

Since b is 2/5 of the distance from a to c, it is ...

  b = a + 2/5(c -a) = 3/5a +2/5c

  b = (3a +2c)/5 = (3(-8, 3) +2(12, -4))/5 = (-24+24, 9-8)/5 = (0, 1/5)

Point b is (0, 1/5).
