Make a conjecture as to what number comes is next <br> -15,-10,-4, 3, 11, ______

Varvara68 [4.7K]

Given:

The sequence is:

-15,-10,-4, 3, 11, ______

To find:

The next number.

Solution:

We have,

-15,-10,-4, 3, 11, ______

Here, the difference between two consecutive terms are:

$-10-(-15)=-10+15$

$-10-(-15)=5$

Similarly,

$-4-(-10)=6$

$3-(-4)=7$

$11-3=8$

It is clear that the difference difference between two consecutive terms is increasing by 1. So, the next difference must be (8+1)=9.

Let the next number be x. Then,

$x-11=9$

$x=9+11$

$x=20$

Therefore, the next number of the sequence is 20.

How are the graphs of y = | x + 2 | and y = | x | + 2 the same? How are they different?

ruslelena [56]

Answer:

y = | x + 2 | graph is going to the left and y = | x | + 2 is going up

Step-by-step explanation:

They are the same because both will have the same shape. However, they differ because y = |x| + 2 will shift two places up and y = | x + 2 | will shift two places to the left

Help please I'm stuck show and explain your work

Deffense [45]

The expressions D, E, and F represent a correct solution to the equation.

Step-by-step explanation:

Step 1:

First, we need to solve the given equation and find the value of x which satisfies the equation.

$6(x+4)=20, (x+4) = \frac{20}{6} = 3.333,$

$x = 3.333 - 4 = -0.666.$

So the value of x for the given equation is -0.666.

Step 2:

Now we evaluate the values of the six given options to see which ones have an x value of -0.666.

A. $\frac{20-4}{6}= \frac{16}{6} = 2.666,$

B. $\frac{1}{6} (20-4)= \frac{1}{6} (16)=\frac{16}{6} = 2.666,$

C. 20 -6 -4 = 20 - 10 = 10.

D. $\frac{20}{6} -4= 3.333 - 4 = -0.666,$

E. $\frac{1}{6} (20-24) = \frac{1}{6} (-4)= -0.666,$

F. $(20-24)\frac{1}{6} = (-4)\frac{1}{6} = -0.666.$

So the options D, E, and F represent a correct solution to the given equation.
