Answer:

Step-by-step explanation:

For x and y to have a proportional relationship, then

the ratio of k = $\frac{y}{x}$ must be equal for all points

(2, 5) → k = $\frac{5}{2}$ = 2.5

(3, 7.5) → k = $\frac{7.5}{3}$ = 2.5

(5, 12.5) → k = $\frac{12.5}{5}$ = 2.5

(18, 8) → k = $\frac{18}{8}$ = 2.25 ≠ 2.5

k is not equal for all values , hence no proportional relationship exists

Answer:

$y=2.75$ units.

Step-by-step explanation:

We have been given that the bottom of a vase is a square. Each side measures y+11 units. The square has a perimeter of 55 units.

Since we know that all sides of square are of equal measure and the perimeter of a square is 4 times the length of each side.

$\text{Perimeter of square}=4\times\text{Length of each side}$

Upon substituting our given values in above formula we will get,

$55=4\times (y+11)$

Upon distributing 4 we will get,

$55=4y+44$

Upon subtracting 44 from both sides of our equation we will get,

$55-44=4y+44-44$

$11=4y$

Upon dividing both sides of our equation by 4 we will get,

$\frac{11}{4}=\frac{4y}{4}$

$2.75=y$

Therefore, the value of y is 2.75 units.

What is the prime factorization of 1,260?

maks197457 [2]

A. 2*2*3*3*5*7

Whilst B and C both also yield 1,260, they aren't broken down in to their prime factors. In B, 4 can be broken down in to 2*2 and 9 in to 3*3, and in C, 6 can be broken down in to 2*3

And D just doesn't total 1,260

Can someone help me ?

Answer:

10 > v (if you don't trust me, check it yourself. Subsitute v for 10 in the first equation.

Step-by-step explanation:

1) 7 > v - 3

2) add 3 to both sides

3) so 7 plus 3 equals 10

So you basically do this

7 > v - 3 (ad 3 to both sides)

You get 10 > v (which is as simplified as possible)

Hope this helps! :)
