Answer:

-2/3

Step-by-step explanation:

We have two points on the line

(0,4) and (6,0)

We can use the slope formula

m = (y2-y1)/(x2-x1)

= (4-0)/ (0-6)

= 4/-6

-2/3

The length of a 200 square foot rectangular vegetable garden is 4feet less than twice the width. Find the length and width of th

inna [77]

Answer:

Length = 18.099 ft

Width = 11.049 ft

Step-by-step explanation:

let the length of the field be x ft

and the width be y ft

as per the condition given in problem

x=2y-4 -----------(A)

Also the area is given as 200 sqft

Hence

xy=200

Hence from A we get

y(2y-4)=200

taking 2 as GCF out

2y(y-2)=200

Dividing both sides by 2 we get

$y(y-2)=100$

$y^2-2y=100$

subtracting 100 from both sides

$y^2-2y-100=0$

Now we solve the above equation with the help of Quadratic formula which is given in the image attached with this for any equation in form

$ax^2+bx+c=0$

Here in our case

a=1

b=-1

c=-100

Putting those values in the formula and solving them for y

$y=\frac{-(-2)+\sqrt{(-2)^2-4 \times (-1) \times 100}}{2 \time 1}$

$y=\frac{-(-2)-\sqrt{(-2)^2-4 \times (-1) \times 100}}{2 \time 1}$

Solving first

$y=\frac{2+\sqrt{4+400}{2}$

$y=\frac{2+\sqrt{404}{2}$

$y=\frac{2+20.099}{2}$

$y=\frac{22.099}{2}$

$y=11.049$

Solving second one

$y=\frac{-(-2)-\sqrt{(-2)^2-4 \times (-1) \times 100}}{2 \time 1}$

$y=\frac{2-\sqrt{4+400}{2}$

$y=\frac{2-\sqrt{404}{2}$

$y=\frac{2-20.099}{2}$

$y=\frac{-18.99}{2}$

$y=-9.045$

Which is wrong as the width can not be in negative

Our width of the field is

y=11.099

Hence the length will be

x=2y-4

x=2(11.049)-4

x=22.099-4

x=18.099

Hence our length x and width y :

Length = 18.099 ft

Width = 11.049 ft

Look at the two patterns below: Pattern A: Starts at 5 and follows the rule "add 6" Pattern B: Starts at 5 and follows the rule

OleMash [197]

Answer:

The first five terms in Pattern A are 5, 11, 17, 23, and 29

Step-by-step explanation:

Pattern A:

5 + 6a

Pattern B:

5 + 3a

Take a = 1 and compare ;

Pattern A:

5 + 6(1) = 11

Pattern B:

5 + 3(1) = 8

A ≠ 2B

B ≠ 1/3A

First 5 terms in pattern A :

Pattern A:

5 + 6(1) = 11

5 + 6(2)= 17

5 + 6(3) = 23

5 + 6(4) = 29

5 + 6(5) = 35

Pattern B cannot have a term 0 as it starts from 5
