The difference between two number is 3.take the numbers as x and y form a equation?
Dennis_Churaev [7]

The difference between two numbers are 3 and numbers are x and y so the equation is x-y=3

How to find the equation and what is the equation ?

equation, statement of equality between two expressions consisting of variables and/or numbers. In essence, equations are questions, and the development of mathematics has been driven by attempts to find answers to those questions in a systematic way.

if the difference of two numbers are 3

And one number is x and another is y

So we write the equation with operation of subtraction

x-y=3

Need urgent help in mathematics!!  Will mark brainliest!!!!

Simply find the total medium cofees sold
then divide that by the number of medium cofees that weren't caffeinated

so..
66 \div 44 = x
then
100 \div x = percentage

so x will be 1.5 & 100 ÷ 1.5 = 66.666...
rounded is 67%

Can someone please answer this, ill give you brainliest Would be very appreciated.
Svetllana [295]

Explanation:

f(x) = (x-4)(x+2)

1) For x-intercept, y will be 0

  • (x-4)(x+2) = 0
  • (x-4) =0, (x+2) = 0
  • x = 4, x = -2

<u />

<u>x-intercept</u>: (4, 0), (-2, 0)

2) For vertex: x = -b/2a where ax² + bx + c

<u>Quadratic function</u>:

  • (x-4)(x+2)
  • x² +2x-4x -8
  • x² -2x -8

<u>vertex</u>:

  • x = -(-2)/2(1)
  • x = 1

y: (x-4)(x+2) = (1-4)(1+2) = -9

ordered pair of vertex: (1, -9)

3) For y-intercept, x will be 0

  • (x-4)(x+2)
  • (0-4)(0+2)
  • -8

<u>y-intercept</u>: (0, -8)
