Mathematics

tester [92]3 years ago

Answer: Most of them cross each other once so I am not sure which one is the answer (sorry)

Step-by-step explanation:

x+y=7 is parallel to 3x+3y=3 and -6x-6y=3

3x+y=-1 and 6x+2y=-2 have infinite solutions togther (both are on top of each other)

The rest of the ways cross each other once

Juli2301 [7.4K]

Answer:

y= -3/5x + 12/5

Step-by-step explanation:

<u>Remember, the formula is y= mx + b</u>

#1 So we're gonna put it into that order by subtracting 3x from both sides:

3x + 5y= 12

-3x           -3x

We are left with this:

5y= -3x + 12

#2 Now we will divide 5 to both sides to isolate the variable

5y/5= -3x/5 + 12/5

#3 Now that the variable is isolated we are left with the answer:

y= -3/5x +12/5

Hope this helps :)

11. The preferred overall competition area in judo, including the mats, is a square with an area of 256 m2.
choli [55]
<span>a) We know that the correct answer will be the square root of 256 since the competition area is a square with an area of 256 meters. And since 10^2 = 100 which is less than 256, the answer has to be greater than 10. And since 20^2 = 400 which is greater than 256, the answer also has to be less than 20. Therefore the answer has to be between 10 and 20. b) The last digit has to be either a 4 or a 6. The units digit is the only digit that will contribute to the units digit of the square. And 0^2 = 0, 1^2 = 1, 2^2 = 4, 3^2 = 9, 4^2 = 16, 5^2 = 25, 6^2 = 36, 7^2 = 49, 8^2 = 64, 9^2 = 81. Of the 10 possible digits, only the values 4 and 6 have a square that has an units digit of 6. c) The square root of 256 based up (a) and (b) above has to be either 14, or 16. So the dimensions are either 14x14 meters or 16x16 meters.</span>
