If x2 + y2 = 14 and xy = 5, find the value of (1/2 x + 1/2 y)2.

aleksley [76]

Answer:

(½x+½y)²=6

Step-by-step explanation:

x^2 + y^2 = 14, xy=5

(A+B)^2=A^2 +2AB+B^2... (*)

(1/2x+1/2y)^2 =(*)

(1/2x)^2 +2(1/2x)(1/2y)+(1/2y)^2 =

1/4x^2 +1/2xy+1/4y^2=

1/4(x^2 +y^2) +1/2(xy)=

1/4*14+1/2*5=

14/4+5/2=

14/4+10/4=

24/4=6

let me know if I'm wrong.

Complete the table of inputs and outputs for the given function. F(x)= -5(x+7)

levacccp [35]

The table of inputs that satisfy the given function is (<em>-2, 25), (-1, -30), (0, 35), (1, -40) and (2, -45).</em>

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Given the function f(x) = -5(x + 7)

When x = -2; f(-2) = -5(-2 + 7) = -25

When x = -1; f(-1) = -5(-1 + 7) = -30

When x = 0; f(0) = -5(0 + 7) = -35

When x = 1; f(1) = -5(1 + 7) = -40

When x = 2; f(2) = -5(2 + 7) = -45

The table of inputs that satisfy the given function is (<em>-2, 25), (-1, -30), (0, 35), (1, -40) and (2, -45).</em>

Which is the graph of the function f(x) = -√x?

Virty [35]

Answer:

Step-by-step explanation:

The last (fourth) graph is that of the parent function y = √x. The negative sign in front of √x leads to reflection of this parent function graph in the x-axis. Thus, the correct graph of f(x) = -√x is the first one.

write the standard form of the line that passes through the given point. include your work in your final answer. (6,1)and (5,4)

bezimeni [28]

We are given two points on a line. First we need to find the slope of the line using these two points.

The given points are (6, 1) and (5, 4). The slope (m) of the line will be:

$m= \frac{4-1}{5-6} =-3$

Using the slope and the point (6,1) we can write the equation in point slope form as:

y - 1 = -3(x -6)

y = -3x + 18 + 1

y = -3x + 19

In standard form, the equation will be:

3x + y = 19
