Answer:
-7
Step-by-step explanation:
2.5x - x + 10 = x - x - 0.5
1.5x + 10 - 10 = -0.5 - 10
1.5x/1.5 = -10.5/1.5
x = -7
First of all, we can factor a factor of from all terms:
Then, we can factor from all terms:
To factor the quadratic expression in parenthesis, we must find its roots, which are and . This implies
So, the complete factorization is
The rule for a rotation by <span>180
</span>(x,y)→(−x,−y)
so B<span>(6,12) will be B'(-6, -12)
answer
</span>B'(-6, -12)
Answer:
The function is:
y = 150*x
where y is the number of calories consumed, and x is the number of pieces of candy consumed.
Now, the domain of a function is the possible values of x that you can input in the function.
For this particular case you can have:
x = 0 (no pieces candy)
x = 1 (one piece of candy)
x = 2 (two pieces of candy)
Notice that x can be only whole numbers because, in principle, you can't eat a fraction of a piece of candy.
So we only use x = whole numbers.
Then the domain of the function is equal to all the natural numbers plus the zero, or:
D = {x ∈ N ∪ {0}}
"x belongs to the union between the set of the natural numbers and the zero"
