A rectangular boat dock has an area of 432 square feet and a length of 18 feet. Which is the perimeter of the boat dock?

Answer:

slope is -1/5 and 9 is the y intercept

Step-by-step explanation:

Answer:6 1/4

Step-by-step explanation:

Answer:

The slope is 2!

Step-by-step explanation:

To find the slope of a line, you must first find two points that are EXACTLY on the grid.

Two points I picked are (-1, -2) and (0,0).

Now count how many points the numbers are far from each other up and down. So, starting from (-1,-2) to (0,0), the points are two points away from each other vertically (on the y-axis)

Now find how far they are on the x-axis

Once again I counted and they are 1 point away from each other horizontally.

Now you need to turn these two points into a fraction.

Slopes are rise/run or y/x

So:

The slope is 2/1.

Also, the slope is positive as the line ascends (goes up).

If the line were negative or going down, the slope would be negative, but the line is positive.

So, the answer is 2!

Logic

Answer:

x= 10, x=1

Step-by-step explanation:

(x-1)(x-10)=0

then solve for x

Answer:

The solution is given below:

Step-by-step explanation:

Given that

The equation is 4.2x

It could present the total price for the no of goods

Here we take an example

The price per chips is $4.2

And, the number of chips purchased be x

And, the total price would be y

So if 5 chips were purchased, so the total price would be

y = $4.2 (5)

= $21

hence, the above represent the description

Answer:

I am not shure, but I think it is C.

Answer:

x int = (2/3,0)

y int = (0,4)

Step-by-step explanation:

x intercept y=0

6x+0=4

6x=4

x=4/6

x=2/3

(2/3,0)

y intercept x=0

6(0)+y=4

y=4

(0,4)

Answer:

(0,4) and ([tex]\frac{2}{3}[/tex], 0)

Step-by-step explanation:

6(0) + y = 4

y = 4

(0,4)

6x + 0 = 4

6x = 4

x = [tex]\frac{2}{3}[/tex]

([tex]\frac{2}{3}[/tex], 0)

Answer:

that's correct... 8√3 is the correct answer

Step-by-step explanation:

sin 30°=1/2

1/2=4√3/x

simplify and you're done ☺

Answer:

C = 8squareroot3

Step-by-step explanation:

x = 4squareroot3 * 2

Answer:

C because not all rhombuses are squares

Answer:

y= -2x-9

Step-by-step explanation:

x would move left or right, and up and down is y

left or down are negative and up or right are positive

just trust me i had this question and i had a 100

Answer:

(x,y)=(4,6)

Step-by-step explanation:

3x+4y=36

y=-1/2 x+8

step 1: substitute the value of y

[tex]3x+4(-\frac{1}{2}x+8)=36[/tex]

step 2: solve equation for x

[tex]3x+4(-\frac{1}{2}x+8)=36[/tex]

3x-2x+32=36

x+32=36

x=36-32

x=4

step 3: substitute the value of x

[tex]y=-\frac{1}{2} (4)+8[/tex]

Step 4: solve equation for y

[tex]y=-\frac{1}{2} (4)+8[/tex]

y=-2+8

y=6

there for the answer is

(x,y)=(4,6)

Answer:

1) -5+(-1)+7

-6+7

=1

2) 19+(-3)+6

16+6

=22

Answer:

1: 1

2: 22

Step-by-step explanation:

1 ) -5 + (-1) is -6, because they both have the same sign.

-6+7} when there is a negative and a postive, put the postive in front

so it will look like this 7-6 which is 1

2) 19+(-3) is basically 19-3, which is 16, and 16+6=22

Extra note:

when you see n+(-n), always remove the + sign and subtract

when you see -n+n, always switch the roles of the two

when you see -n+-n, remove the - sign and add it back later

when you see -n-n, think of -n+n

I hope these helps :)

Answer:

k=1/4

Step-by-step explanation:

x² - 5kx+ k=0  ....(1)

suppose 2 roots: a and 4a

(x-a)(x-4a)=0

x² - 5ax + 4a² = 0 ....(2)

compare (1) and (2): -5a = -5k              a=k

4a² = k                4a² = a   (substitute)

a(4a-1) = 0

a = 0 or a = 1/4        (if a=0   k=0 and x=0 is not the solution)

a = 1/4      k = 1/4

(a₂ = 1/4 * 4 = 1)

Answer:

k = 1/4.

Step-by-step explanation:

Let the roots be  r and 4r   and using the fact that sum of the roots = -b/a and product = a/c, we have:

r + 4r = -(-5k)

r*4r = k

5r = 5k

4r^2 = k

From the 3rd equation:

r = k, therefore:

4k^2 = k

4k = 1

k = 1/4.

Answer:

1. 6

2. 4

3. 10

4. Not sure about this one but I think 3

Answer:

its 12

Step-by-step explanation:

Answer:

10

Step-by-step explanation:

Answer:

for level 1: x=36

because you just need to do 180-144

for level 2: x = 127

you can just so 180-15-38

for level 3: x = 36

because you start by setting an equation like this:

92 + (2x+16) = 180

subtract 92 from both sides, then subtract 16 from both sides, and finally divide both sides by 2 to get 36
