Relabel the spot that you have as M. (The reason we are keeping this coordinate is because it is correct just labeled wrong. It lines up perfectly with G and O both)

G is in the wrong spot, you have it in (2,2) it needs to go down 4 places to the coordinates (2, -2)

E will be located directly under O and directly across from G. So, it will be at the coordinates (-4, -2)

Very easy just put a : in between 9 and 17!! hope thats helpfull!!!!!

c is the most precise, because you are going to the furthest decimal point which is more helpful in pinpointing the exact location.

Answer:

A parallelogram whose vertices have coordinates R(1, -1), S(6, 1), T(8, 5), and U(3, 3) has a shorter diagonal of √(13) units.

Step-by-step explanation:

RSTU is parallelogram. The vertices of the parallelogram are R(1, -1), S(6, 1), T(8, 5), and U(3, 3).

Two opposite vertices are connected by the diagonal of a parallelogram. So, RT and SU are two diagonal.

Distance formula:

Using this formula we get

Therefore the parallelogram whose vertices have coordinates R(1, -1), S(6, 1), T(8, 5), and U(3, 3) has a shorter diagonal SU of √(13) units.

Here it is graphed... But I'm not sure what the x value of R would be... I know its Y value is 2

Linear equation with the form y=mx+b

m=1/4 (given) & it passes through (0.4, - 0.5)

Let's calculate b; -0.5 = (1/4)(0.4) + b
-0.5 =0.25(0.4) + b
-0.5 - 0.1 = b  -0.6
y= 0.25x - 0.6
y intercept is calculated for x=0
Then y intercepts =-0.6 

Elaine brought more salad to the picnic.
To figure this question out, you have to make the fractions have common denominators. The LCM (Least Common Multiple) of 3 and 4 (the denominators of the fractions) is 12. 
3/4= 9/12 (Elaine) (Numerator times 3, Denominator times 3)
2/3= 8/12 (Jake) (Numerator times 4, Denominator times 4)

Answer:

The set of integers which form a Pythagorean triple is:

5,12,13

Step-by-step explanation:

We are asked to find the set of integers such that they form a Pythagorean triplets.

Three integers a,b,c are said to form a Pythagorean triplets if they satisfy the property:

1)

3,5,6

and

Hence option: 1 is incorrect.

2)

5, 12, 13

and

This means:

Hence, option 2 is correct.

3)

15,9,17

Also,

Hence, option 3 is incorrect.

4)

6,8,12

and:

Hence, option 4 is incorrect.

Ok, this is what I got.

Hope this helps you. ;)

Answer:

pH = 2

Step-by-step explanation:

To graph the pH function :

The range of the pH function varies from 1 to 14

And the concentration of hydrogen ion goes from 0 to 1

Taking pH value on y-axis and concentration of hydrogen ion on x-axis, The resultant graph is attached below :

Given : Concentration of hydrogen ion = 0.01

Now, pH = -log(0.01)

Um..... probably 500 cause  200 less is 300 and 200 more is 700

I feel that it would be (7,2) :)

Answer: =50

Explanation: An unknown leg of a right triangle can be found using the Pythagorean theorem. Pythagorean theorem: a²+b²=c²

a²=14²+48²

a²=14²=14*14=196

a²=48²=48*48=2304

a²=196+2304

a²=196+2304=2500

a²=2500

a²=(25*100)=2500

a=5*10=50

A=50

Hope this helps!

Thanks!

Have a great day!

x = -4y+3

-x-4y = -3

________________

x+4y = 3

-x-4y = -3

0 = 0

It's congruent I think

The answer:
first, the angle of elevation, the shadow and the statue form an right triangle.
so, we know that for computing tangent, we use the main formula:

Tan = opposite side / adjacent side
let x be the length of the statue, it is the opposite side
30 feet long is the adjacent side
therefore, 
tan50°= x /30, 1.19 * 30= x, and the x=35.75 feet

Let C be the number of cars and T the number of trucks:

C + T =24

but C = 2T

2T + T = 24

3 T =24 band T =8 so C=16

Since 150 can't go into 250 twice as a whole, you know that the percentage is over 50% . To find the percentage (I think, bad memory) You need to find the difference or increase between the two. 250 / 150 = 100 Then divide the increase or difference by the original number (As in 150) then multiply that by 100. The percentage would be 66% 

Hope this helps, though would ask someone again just to be sure

Amount-drained=amoutleft
drained=12 times t
amount=550

550-12t=amountleft
or A(t)=-12t+550

A monomial is an algebraic expression consisting of a single term.

The answer to this question is 8

F(x) = (-x²+x+20) / (x+4)

-x²+x+20     | x+4
+x²+4x          -x+5
 \\\\ 5x+20
     -5x-20
      \\\\\\\\\
 
 f(x) = (x+4)(-x+5) / (x+4)
 
 f(x) = (-x+5)

The graph is a decreasing line, with origin from 5.

There are total 12 letters. 3 from them are the letter A.
The probability that the drawn letter is A can be calculated:
P(A)=number of events "letter A occurs"/ number of possible events that may occur 
P(A)=3/12
a. as a fraction: 3/12=1/4
b. as a decimal: 0.25
c. as a percent: 25%

-1.75 is the slope of the line.

Use the formula y2 - y1 / x2 - x1 to find the slope of a line.
Plug in the numbers in your coordinates.

y2 - y1 / x2 - x1
2 - (-5) / -3 - 1
7 / -4
-1.75

Hope this helps!!

A=P(1-24/100)⁸

15,542 =P(0.76)⁸

P= (15,542)/(0.76)₂

P= 15,542/0.111303

P = 139,836
