28/7 =4
7•4 is 28 or
7+7+7+7 is also 28
Option 1:
is the correct answer
Step-by-step explanation:
We can put the values of x in each option one by one and then compare the output to find the best option
So,
<u>For y = 5x+5:</u>
Putting x=1,2,3,4,5...

The values of x in the function are producing the output values of y, which means that the function for values given in the table is defined by: y= 5x+5
Hence,
Option 1:
is the correct answer

This one is so easy that your brain refuses to accept it.
It's looking for a harder answer, but can't find it !
You're totally correct, as far you went. x² + 2x does = -1
Now add ' 1 ' to each side: x² + 2x + 1 = 0
Can you factor that quadratic ?
Can you mash it through the quadratic formula ?
Actually, it's the simplest possible perfect square.
x² + 2x + 1 = (x + 1)²
So the solutions of x² + 2x + 1 = 0 are both x = -1 .
Don't say anything.
I know it's embarrassing.
