There are 6 dimes and a total of 36 coins in all so the part to whole ratio is 6:36 or 1:6

Total coins = 12 + 6 + 18 = 36

dimes = 6

All = 36

Part-to-whole ratio of dimes to all = 6 : 36 = 1:6

Use the remainder theorem to divide 5x^2+9x-2 by x+3. What is the remainder
marishachu [46]

Answer:

16

Step-by-step explanation:

Given

f(x)=5x^2+9x-2

Remainder theorem states that when f(x) is divided by x-a then the remainder can be calculated by calculating f(a).

Now Using the remainder theorem to divide 5x^2+9x-2 by x+3 to find the remainder:

f(x)=5x^2+9x-2

f(-3) = 5(-3)^2 +9(-3) -2

       =5(9) - 27 -2

       = 45-29

        = 16 !

What is the slope of this graph? −14 4 14 −4 Number graph ranging from negative 10 to 10 on both the x and y axis. A line passes
spin [16.1K]

The slope of this graph is - 4

Step-by-step explanation:

The slope of a line is m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} , where

  • (x_{1},y_{1}) and (x_{2},y_{2}) are two points on the line
  • The slope of a horizontal line is zero
  • The slope of a vertical line is undefined

∵ The graph is a line

∵ The line passes through points (1 , -2) and (0 , 2)

∴ x_{1} = 1 and x_{2} = 0

∴ y_{1} = -2 and y_{2} = 2

- Substitute these values in the rule below

∵ m=\frac{y_{2}-y_{1}}{x_{2}-x_{2}}

∴ m=\frac{2--2}{0-1}=\frac{4}{-1}

∴ m = - 4

The slope of this graph is - 4
