Answer:
d
Step-by-step explanation:
3x^2+26+35
ac method
3x35=105
105/5=21
21+5=26
3x^2+5x+21x+35
x(3x+5)7(3x+5)
(x+7)(3x+5)
Angle A=36 degrees
angle B=54 degrees
36+54=90
Answer:
y = x^2 - 3
Step-by-step explanation:
<u>Quadratic function in general form:</u>
The graph opens up if a>0, opens down if a < 0
<u>The function that opens up is:</u>
Answer:
Yes it is an equivalence relation
Explanation:
An equivalence relation is a binary relation between two values that are symmetric, transitive and reflexive. In other words, when we say a value x is equal(using "=") to a value y, there is an equivalence relation between them.
Example, given set {x, y, z} where ~ means equivalence:
x ~ y if y ~ z means symmetric
since x ~ y and y ~ z, then x ~ z means transitive
x ~ x means reflexive
Equivalence relations share a common attribute or attributes(example, a satisfying condition)
The above condition that two states are related from the set of all US states if they have a border in common satisfies the condition of equivalence listed hence it is an equivalence relation.
Could I ask, is there anything else that can be used to help solve the problem?
