Answer:

B

Step-by-step explanation:

Given a polynomial divided by a factor (x + h) then the remainder is f(- h)

Given

f(x) = 3x^{4} + 2x³ - x² + 2x - 19 divided by (x + 2)

To find remainder evaluate f(- 2)

f(- 2) = 3(-2)^{4} + 2(- 2)³ - (- 2)² + 2(- 2) - 19

        = 3(16) + 2(- 8) - 4 - 4 - 19

        = 48 - 16 - 4 - 4 - 19

        = 5 → B

grin007 [14]

In y = mx + b form, the slope can be found in the m position and the y intercept can be found in the b position.



y = mx + b


y = 2x + 15


slope(m) = 2 and y int (b) = 15



The initial amount is the y intercept, which is 15. The rate of change (the slope) is 2


example :  


baskets picked in 1 hr :


y = 2(1) + 15


y = 2 + 15


y = 17



baskets  picked in 2 hrs :


y = 2(2) + 15


y = 4 + 15


y = 19



so the slope ( rate of change) is basically saying for every hr of picking, you pick 2 baskets...so your picking 2 baskets per hr.


The y intercept (15) is telling us that they already had 15 baskets to start with.

Using the information in the customer order, determine the length and width of the garden. Enter the dimensions. ↓
SashulF [63]

Answer:

Length: 14 feet   Width: 1 foot

Step-by-step explanation:

This is the only way to have a rectangle that has a perimeter of 30 feet, and an area of 14 feet.

For perimeter:

14 + 14 = 28

1 + 1 = 2

2 + 28 = 30

These dimensions have a perimeter of 30.

For area:

14 x 1 = 14

These dimesnions also have an area of 14.

So, 14 and 1 are the correct dimensions!
