Answer:

Option d:slope of function B=- Slope of function A.

Step-by-step explanation:

We are given that one equation for function A and the graph for function B

Function A

f(x)=-2x+1

Function B : The graph of line going through ordered pair (-1,-5) and (2,1) and (3,3)

The equation of a line passing through two points (x_1,y_1) and (x_2,y_2) is given by

\frac{y-y_1}{y_1-y_2}=\frac{x-x_1}{x_1-x_2}

The equation of function B passing through the points (-1,-5) and (2,1)

\frac{y+5}{-5-1}=\frac{x+1}{-1-2}

Where x_1=-1,y_1=-5,x_2=2,y_2=1

The equation of function B passing through the points (-1,-5) and (2,1)

\frac{y+5}{-6}=\frac{x+1}{-3}

The equation of function B passing through the points (-1,-5) and (2,1)

{y+5}=2(x+1)

The equation of function B passing through the points (-1,-5) and (2,1)

2x-y=5-2

The equation of function B   passing through the points (-1,-5) and (2,1)

2x-y=3

The equation of function B  passing through the points (-1,-5) and (2,1) is given by

y=2x-3

Therefore, slope of function B=2

By comparing with the equation of line

y=mx+c

Slope of function A= -2

Therefore, slope of function B=- Slope of function A.

Hence, option d is true.

ki77a [65]

Answer:

x^2 + 2xy + y ^2

Step-by-step explanation:

A = a^2

a = x + y

(x + y) + (x + y)

x^2 + xy + xy + y^2

x^2 + 2xy + y ^2

6. what is the parimeter of triangle ABC<br>8. What is the value of x​
nalin [4]

<u>Answer:</u>

Perimeter = 20 units

x = 120°

<u>Step-by-step explanation:</u>

We are given a triangle ABC with known side lengths for all three sides and an inscribed circle.

We are to find the perimeter of triangle ABC and the value of x.

Perimeter of triangle ABC = 2 + 2 + 5 + 5 + 3 + 3 = 20 units

The kite shape at the end is a quadrilateral which has a sum of angles of 360 degrees.

Two out of four angles are right angles and one is 60 so we can find the value of x.

x = 360 - (90 + 90 + 60) = 120°
