Answer:
See below.
Step-by-step explanation:
1)
So we have:
This can be interpreted as:
"There exists a natural number <em>x</em> and an integer <em>y</em> such that x² is equal to y²."
2)
So we want even numbers are in the set of integers.
This is interpreted as:
"The set of even numbers (2n such that n is an integer) is in the set of integers"
Answer:
you can add 3x and 2x
Step-by-step explanation:
you can add them because they are both like terms
Answer:
Step-by-step explanation:
All the absolute value functions given in the option are of the form:
, where (h,k) is the vertex
From your description the absolute value graph has vertex at (-4,-2)
Hence h=-4 and k=-2.
We substitute to get:
We simplify to get:
Factors:
10 = 5*2
12 = 2*2*3
Least common multiple: 2*2*3*5
=60
you will need 6*10 = 60 or 6 packets of pencils
and 5*12 = 60 and 5 packets of erasers
