Answer:
3/5
Step-by-step explanation:
7/15 + 2/15 = 9/15
both 9 nad 15 are divisible by 3
9/15 = 3/5
Answer:
D) 3x^2 - 12
Step-by-step explanation:
Using PEMDAS;
There is no need to evaluate the part of the equation (x^2 - 8) because is no need to, as it is already in its simplest form.
We must evaluate the part of the equation continuing with, "- (-2x^2+4)," as it is not in its simplest form.
Evaluating "- (-2x^2+4)":
Step 1: Distributing the negative
Once distributing the negative symbol amongst the values within the parenthesis according to PEMDAS, we get "2x^2 - 4" as the product.
Step 2: Consider the rest of the equation to evaluate
Since the part of the equation is still in play here as it is a part of the original equation to be solved, we must evaluate it as a whole to get the final answer.
Thus,
x^2 -8 + 2x^2 - 4 = ___
*we can remove the parenthesis as it has no purpose, since it makes no difference.
Evaluating for the answer, we get,
x^2+2x^2 + (-8 - 4) = 3x^2 - 12
Hence, the answer is D) 3x^2 - 12.
Answer:
the slope is 3
Step-by-step explanation:
To do this we need to move 10 to other side. To accomplish this you just need to add 10 to both side since (-10)
so
A+ 10 = c -10 + 10
we get
A+ 10 = c
lets say it wasn't -10 but positive 10.
A = c + 10 then we would subtract 10 from both sides
A -10 = c + 10 - 10
we get
A - 10 = C
Answer:
The domain of relation is {1,3,5}
It is not a function.
Step-by-step explanation:
Given the relation {(1, 4), (3, 6), (5, 4), (1, 8)}
We need to find the domain and determine if the given relation is function or not.
The domain of relation is {1,3,5}
But the given relation is not function because we have x=1 twice in the relation and the for the relation to be function the values of domain can't be repeated.
So, It is not a function.
