F(x) = 1/4x + 2

This means that the y-intercept is 2 and the slope is 1/4.

Hope this helps!

The function that best describes this graph would be f(x)=1/4x+2. The y-int is 2 and it rises once and runs 4 times to the right.

1.
w - the width
w + 6 - the length
40 - the area

Equation: w · (w + 6) = 40

w² + 6w = 40 |-40
w² + 6w - 40 = 0
w² + 10w - 4w - 40 = 0
w(w + 10) - 4(w + 10) = 0
(w + 10)(w - 4) = 0 ↔ w + 10 = 0 ∨ w - 4 = 0
w = -10 < 0; w = 4

The width is equal 4 ft.
The length is equal 4 + 6 = 10 ft.

2.
f(x - n) - right n units
f(x + n) - left n units
f(x) - n - down n units
f(x) + n - up n units

f(x) = x² - 3x - 4
f(x - 3) = (x- 3)² - 3(x-3) - 4

right 3 units.

Find the distance between P(2, 8) and Q(5, 3).

swat32

Answer:

The distance (d) between two points (x1,y1) and (x2,y2) is given by the formula

d = √ ((X2-X1)2+(Y2-Y1)2)

d = √ (5-2)2+(3-8)2

d = √ ((3)2+(-5)2)

d = √ (9+25)

d = √ 34

The distance between the points is 5.8309518948453

The midpoint of two points is given by the formula

Midpoint= ((X1+X2)/2,(Y1+Y2)/2)

Find the x value of the midpoint

Xm=(X1+X2)/2

Xm=(2+5)/2=3.5

Find the Y value of the midpoint

Ym=(Y1+Y2)/2

Ym=(8+3)/2=5.5

The midpoint is: (3.5,5.5)

Graphing the two points, midpoint and distance

P1 (2,8)

P2 (5,3)

Midpoint (3.5,5.5)

The length of the black line is the distance between the points (5.8309518948453)

Find the slope of the line connecting the two points

Slope = (Y2-Y1) = (3-8) = (-5) = -1.66666666666667

(X2-X1) (5-2) (3)

Find the equation of the line passing through the two points

The general equation for a straight line is

y = mx + b

Where m represents the slope of the line which we found in the previous step to be -1.66666666666667

y = -1.67x + b

We substitute x and y for the values from one of our points (2,8)

8 = -1.67×2 + b

8 = -3.33 + b

8--3.33 = b

11.33 = b

Knowing both b and m, we can contruct the equation of the line

y= -1.67x+ 11.33

X and Y intercepts

The x-intercept is a point on the graph where y is zero

Using the equation we found in the previous step and substituting zero for y

y= -1.67x+ 11.33

0= -1.67x+ 11.33

1.67x= 11.33

x= 11.33/1.67 = 6.80

The x intercept for this straight line is 6.80

The y-intercept is a point on the graph where x is zero

Using the equation we found in the previous step and substituting zero for x

y= -1.67×0+ 11.33

y= 11.33

The y intercept for this straight line is 6.80

if someone could explain how to evaluate absolute value to me I would appreciate it and maybe you could explain how to solve the

MAVERICK [17]

When calculating absolute value (like those questions above) you do whatever is in the absolute value bars first (if its just a number then.... just make the number positive, even if it is negative or already positive) and whatever answer you get inside those absolute value bars will ALWAYS be positive unless it's like -[4} then it's a negative number bcz the positive outcome that comes out of the absolute value bars gets multiplied by -1 (or just turned negative). So, for the first one you do 22+48=70 and -7--20=13 and then make the outcome of both of those positive and then subtract them from each other 70-13=57. For the second one you do 7+-33=-26 and 4+16=20 and make the outcome of both of those positive and then you add 26+20=46 and so and so on for the other problems.
