Step-by-step explanation:

Let's call Ahmed's number x,

If he multiplies it by 2, it becomes 2xHe then divides it by 5 so it would be 2x ÷ 5The result was 4, so it would be written as 2x ÷ 5 = 4

To solve for x,

First, multiply both sides by 5: 2x = 20Finally divide both sides by 2 to get x on its own: x = 10Answer: He was thinking of the number 10

You could also work backwards:

If he ×2 then ÷5, you would ×5 then ÷2 (doing the opposite):

4 × 5 = 2020 ÷ 2 = 10

Answer:

Step-by-step explanation:

6) y = 2x² + 6x - 80

1) y = 2*x² + 2*3x - 2*40

y = 2 [ x² + 3x - 40]

2) Sum = 3

Product = -40

Factors = (-5) ; 8 {-5 +8 = 3 ; (-5)*8 = -40}

y = 2 [ x² + 8x - 5x - 40]

= 2 [ x(x + 8) - 5(x + 8) ]

= 2 [ (x +8) (x - 5)]

y = 2(x +8)(x -5)

b) y = 0

2(x + 8)(X - 5) = 0

x + 8 = 0 ; x - 5 = 0

x = -8 ; x = 5

(-8) ; 5 are the zeros.

Option 4: 0

Step-by-step explanation:

Given the function, f(x) = 3x, and the domain. {-3, 1, 4}:

Substitute the values of each domain as inputs into the function:

x = -3

f(-3) = 3(-3)

f(-3) = -9

x = 1

f( 1 ) = 3( 1 )

f( 1 ) = 3

x = 4

f(4) = 3(4)

f(4) = 12

Therefore, the correct answer is option 4) 0, because there is no input value that provides an output of 0. You were only given three domain values that provided its corresponding outputs.

He sat down at his chair in front of the music stand and smiled eagerly at Nadine, his teacher, who gave him a strange look.Wheres your trombone? she asked.Oh, no! Hed left it on the bus! Whatll I do? he asked, after explaining the situation to Nadine.Youll have to get it back, or your parents are out nine hundred dollars.Oh, no.

But it was six oclock; the bus companys phone recording said that the lost and found closed at five.The next day, Jerrys father drove him to the bus company office, andthe trombone wasnt there.
