By Question it's given that the sum of two numbers is 15 . And we need to find out the numbers. So ,

Let us take :-

First number = x
Second number = x + 1

According to the Question :-

$\sf\implies x + x +1=15\\\\\sf\implies 2x = 15-1\\\\\sf\implies 2x =14 \\\\\sf\implies x =14/2 \\\\\sf\implies\red{ x = 7 }$

Therefore :-

First number = 7
Second number = 8

Hence the two numbers are 7 and 8.

The Midpoint of AB dkdldl

Nutka1998 [239]

The Midpoint of AB is (1,0).

Given that:

In line AB, where the coordinates of A is (3,1) and coordinates of B is (-1,-1).

To find:

The Midpoint of line AB.

So, according the question

We know that,

The midpoint M of a line segment AB with endpoints A (x₁, y₁) and B (x₂, y₂) has the coordinates M ( $\frac{x_1 + x_2}{2} , \frac{y_1 + y_2}{2}$ ).

Now from question,

We know that the the coordinates of A is (3,1) and coordinates of B is (-1,-1) of line AB.

So, we can say that

A is (3,1) or x₁ = 3 and y₁ = 1.

B (-1,-1) or x₂ = -1 and y₂ = -1.

∵ The coordinates of midpoint M (X,Y)

X = $\frac{x_1 + x_2}{2}$

= $\frac{3-1}{2}$

= 2/2

X = 1.

And

Y = $\frac{y_1 + y_2}{2}$

= $\frac{1-1}{2}$

= 0/2

Y = 0.

So, the midpoint of line AB is M (1,0)

Graph the function. Describe its position relative to the graph of the indicated function

sweet [91]

Answer:

Step-by-step explanation:

If the parent function is function $y=f(x)$ and $a>0,$ then

the graph of the function $y=f(x-a)$ is translated a units to the right graph of the parent function;
the graph of the function $y=f(x+a)$ is translated a units to the left graph of the parent function;
the graph of the function $y=f(x)+a$ is translated a units up graph of the parent function;
the graph of the function $y=f(x)-a$ is translated a units down graph of the parent function.

In your case, the grapgh of the function $y=2^x+2$ is translated 2 units up the graph of the function $y=2^x.$
