If y=kx, where k is a constant and y=8 when x=2/3, what is the value of y when x=5/4?

MatroZZZ [7]

Answer:y = 15

Step-by-step explanation:

Given y=kx,

where k is a constant

When y=8 and x=2/3, K =?

y=kx

8= k 2/3

K=(3 x8)/2= 24/2 = 12

K=12

Now when x=5/4 y=?

y= kx

y = 12 X 5/4= 60/4

y = 15

What number must be added to the expression below to complete the<br> square?<br> x² - 18x

kiruha [24]

Answer:

$\boxed {\boxed {\sf 81}}$

Step-by-step explanation:

The standard form of a quadratic is:

$ax^2+bx+c$

To complete the square, the a (leading coefficient) must be 1 and there can only be terms with variables on one side.

The expression given:

$x^2-18x$

follows these rules. Next, we divide the b (linear coefficient) by 2, then square it. Basically:

$(\frac{b}{2})^2$

The b in the expression is -18.

$(\frac{-18}{2})^2$

$(-9)^2= -9*-9= 81$

This is the number that is added.
