Answer:

-3

Step-by-step explanation:

There are two ways to see what the next sequence number would be in this case.

First approach, you start with the first number (1) than count every other number, which are all positive integers. You do the same starting from the second number (-1), which would then be all negative integers.

Second approach, consider 2 consecutive numbers being a single element of the series... each has a number (1,2,3) with its positive and negative values.

Answer:

A"fishbone" diagram

Step-by-step explanation:

A"fishbone" diagram, may help to determine potential causes of an issue and organise concepts into valuable groups of brain storming. A depiction of the fishbone is a graphical way of looking at causes and effects.

It's a more organised solution than other brain storming tools that cause problems. The issue or effect is shown on the fish's head or mouth.

The equation that shows the relationship between x and y is:

y = 5x

A linear equation is in the form:

y = mx + b

where m is the rate of change and b is the initial value of y, y, x are variables.

Let x represent the number of nights knitting and y represent the length of the scarf.

The equation that shows the relationship between x and y is:

y = 5x

Madeline is standing 2x−4 feet from the base of a tree. The height of the tree is 5x+6 feet. Find the equation that shows the st

klemol [59]

Answer:

Required equation is $\sqrt{(2x-4)^2+(5x+6)^2}$ .

Step-by-step explanation:

Given,

Height of the tree=5x+6

Distance from feet of the tree=2x-4

To find straight distance from feet of Madeline to top of the tree.

Let the tree as y-axis and distance from base along x-axis. Then the distence of straight line from foot of Madeline to top is become the hypotenuse of the triangle. Thus if we let,

Distance from feet of Madeline to top of tree= p, then, according to law of finding third side of a triangle we get,

$p^2=(\textit{distance from base})^2+(\textit{height of tree})^2$

$\therefore p=\sqrt{(2x-4)^2+(5x+6)^2}$

Hence the result.
