The line x − y = 2 is on a coordinate plane and contains EF, which is one side of square EFGH. What is the slope of the line tha

Alborosie

Answer:

The slope of FG is -1

Step-by-step explanation:

Given

Square EFGH

EF: $x - y = 2$

Required

Determine the slope of FG

First, we calculate the slope of EF

$x - y = 2$

Make y the subject

$-y = 2 - x$

$y = x -2$

The general equation has the form: $y = mx + b$

Where

$m = slope$

Compare $y = mx + b$ to $y = x -2$

$m = 1$

<em>From the name of the square EFGH, we can conclude that EF and FG are perpendicular</em>

<em />

The relationship between perpendicular lines is:

$m_2 = -\frac{1}{m_1}$

Where

$m_1 = m = 1$ -- Slope of EF

and

m2 = slope of FG

Substitute 1 for m1 in $m_2 = -\frac{1}{m_1}$

$m_2 = -\frac{1}{1}$

$m_2 = -1\\$

<em>Hence, the slope of FG is -1</em>

Given that f(x) = x2 + 5x + 6 and g(x) = x + 2, find (fºg)(x) and

PolarNik [594]

Answer:

$(f\circ g)(x)=x^2+9x+20$

Step-by-step explanation:

We have the two functions:

$f(x)=x^2+5x+6\text{ and } g(x)=x+2$

And we want to find:

$(f\circ g)(x)$

This is equivalent to:

$(f\circ g)(x)=f(g(x))$

Therefore, we will have:

$f(x+2)$

By substitution:

$f(x+2)=(x+2)^2+5(x+2)+6$

Simplify. Square and distribute:

$f(x+2)=(x^2+4x+4)+(5x+10)+6$

Rearrange:

$f(x+2)=(x^2)+(4x+5x)+(4+10+6)$

Combine like terms:

$f(x+2)=(f\circ g)(x)=x^2+9x+20$

Robin's grandmother is 7 times older than him. In 12 years, she will be 3 times as old as him. How old is Robin?

11111nata11111 [884]

Answer:

6 year's old

Step-by-step explanation:

Grandma is G and Robin is R

G=7R

G+12=3(R+12)

G+12=3R+36

7R+12=3R+36

7R-3R=36-12

4R=24

R=6

Robin is 6 years old
