If y = 5x - 3, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?
anastassius [24]

Answer: B. {[-1,-8),0,-3),(3,12) if im wrong sowwy

Step-by-step explanation: One simple way to solve this is that 0 = B

The formula you use in order to solve this is y= mx+b

                                                                       y= 5x-3

As we know the -3 is b and 0 is always equal to -3 C is the only choice with 0 and -3 and in x is o and y is -3 the input is 0 and the ouput is -3

x is always and input while as y is always an output.

Rectangle A has one side which is 6cm long and the other is (x+2)cm long. Rectangle Y has sides of length (2x+1) and 3cm, If the
gregori [183]
Hello, 

Rectangle A:           6cm                  (x+2)cm
Rectangle B:           3cm                  (2x+1)cm

The formula for the perimeter of a rectangle is: P=2(base+height)

Then:

P_A=2(b+h) \\ P_A=2*[6+(x+2)] \\ P_A=2*(x+8) \\ P_A=2x+16 \\  \\  \\ P_B=2(b+h) \\ P_B=2*[3+(2x+1)] \\ P_B=2*(2x+4) \\ P_B=4x+8


But we know that the perimeters are the same, so:

P_A=P_B \\ 2x+16=4x+8 \\ 8=2x \\ \boxed{x=4} \\  \\ Replacing:  \\  \\ Lenght\,\,of\,\,A=(x+2)cm\\ Lenght\,\,of\,\,A=(4+2)cm\\ \boxed{Lenght\,\,of\,\,A=6cm}\\  \\ Lenght\,\,of\,\,B=(2x+1)cm\\ Lenght\,\,of\,\,B=(2*4+1)cm\\ \boxed{Lenght\,\,of\,\,B=9cm}

With the answer of A, we realize that this figure is actually a square.

A rope which is 10.3 centimeters long is cut into 4 pieces of equal length. Write an equation to find the length of
alexdok [17]

Answer: x = 10.3 ÷ 4

Step-by-step explanation: if we were to work this out forgetting about the equation it can be worked out by dividing the 10.3 by 4 to find the length of the pieces so, now to express it as an equation, we have to add x into our sum 4 × ? = 10.3 : 4x = 10.3. The answer for x would be x = 2.58.

Which of the following demonstrates how the 20 is calculated using the<br> combination pattern?
ZanzabumX [31]

Answer:

D

Step-by-step explanation:

The diagram shows Pascal's triangle. Pascal's triangle is a triangular array of the binomial coefficients.

The entry in the n^{th} row (start counting rows from 0) and k^{th} column (start counting columns from 0) of Pascal's triangle is denoted by

C^n_k=\left(\begin{array}{c}n\\ k\end{array}\right)

Coefficient 20 stands in 6th row, then n = 6 and in 3rd column, so k = 3.

Hence,

20=C^6_3=\left(\begin{array}{c}6\\ 3\end{array}\right)=\dfrac{6!}{3!(6-3)!}
