If y = 4x – 1, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?
Helga [31]
Hello!

To do this you will pick an x value, multiply it by the slope and add the y- intercept. Let's try 0.

y=4(0)-1
y=-1

So here, an ordered pair could be (0,-1)

We can try this again for different x-values.

y=4(1)-1
y=3

This gives us the ordered pair  (1,3)

y=4(100)-1
y=399

This would give us the ordered pair (100,399)

I hope this helps!

murzikaleks [220]
She took 100, the store has       - 100
she went back and bough
70 bucks in stuff, the store has - 70

yes, she took the $100 bill and gave it, got back $30, that means she only kept $30 from the original bill.

the store however, lost the original $100 bill plus the $70 in merchandise, so they have -$170.

Factor completely x2 + 20x − 36.
vodomira [7]

Answer:

Prime

Step-by-step explanation:

x² + 20x − 36

You must find a pair of numbers that multiply to give -36 and add to give +20.

The likely candidates are 2 and 18, and they must have opposite signs to give a negative product.

+2 × (-18) = -36; +2 + (-18) =   -16

-2 ×   18  = -36;  -2 +     8   = +16

Neither combination gives +20 as the sum.

The expression can't be factored with rational numbers.

The expression is prime.
