Can someone please help me with 7 and 8

Mathematics

7) So when x=6 then z=72, they are directly proportional, so if I multiply the first with a number, then I have to multiply the second with the same number.
6 becomes 13 (x)  /multiplied with about 2.167/
72 becomes 156(y) /multiplied with about 2.167/

8) Inversely proportional, so if I multiply the first with a number, then I have to divide the second with the same number.
6 becomes 13 (x)
2 becomes ~0.92307(y) /round it to the thousandths place and you get 0.923/

ipn [44]
As we know assets = liabilities + equity

In this case assets would be increased by $76,000 and the liabilities would be increased by $76,000

Which of the following is not a function?
rusak2 [61]
Answer: B

Number on the left: x-value
Number on the right: y-value

If there are 2 y-values for one x-value it is NOT considered a function.

For instance in the answer:

(2,3), (2,4), (3,3), (3,4)

You can clearly see that the x-values (2 & 3) repeat more than once; therefore, it is NOT a function.

On the other hand if you have 2 DIFFERENT x-values for the same y-value it IS A FUNCTION.

For ex D: (2,4), (3,4), (5,4), (6,4)

As you can see there are 4 DIFFERENT x-values with same y-value; therefore it is A FUNCTION

To make it easier:

If x-values appear more than once = NOT A FUNCTION

If x-values appear only ONCE = FUNCTION

Remember: y-values are ALLOWED to repeat

I hope this helps. If you have any questions please let me know in the comments.

Can anybody help me with this
lys-0071 [83]

Answer:

a, y =3/x

x = 0.5 => y = 3/0.5 = 6

x = 1 => y = 3/1 = 3

x = 2 => y = 3/2 = 1.5

x = 3 => y = 3/3 = 1

x = 4 => y = 3/4 = 0.75

b,

y = 3/x passes (0.5, 6) => A is correct

Hope this helps!

Pythagorean theorem to determine if a triangle with sides 2 ft,5ft,4ft is a right triangle
Delvig [45]
a^2 + b^2 = c^2

2^2 + 4^2 = 5^2

4 + 16 = 25

20 = 25

Since 20 = 25 is clearly a false statement, the three side lengths 2 ft, 4 ft, and 5 ft do not form a right triangle.
