Let n be the first even integer, and n+2 will be the second even integer. (Why? Think 2 and 4, 2+2=4. This is the case for every consecutive even integers).
n + 3(n+2) = 54
n + 3n + 6 = 54
4n = 48
n = 12, n+2 = 14
Answer:
f(x) is equal to -1 when x=3
Step-by-step explanation:
we have
This is a constant function
we know that
A <u>constant function</u> is a function whose output value is the same for every input value
therefore
when x=3 (input value)
The value of the function is y=-1 (output value)
Here is how I would show the work for this problem
5- (a-4) = 3 (a+2)
5-a+4 = 3*a+3*2
5-a+4 = 3a+6
-a+9 = 3a+6
-a+9+a = 3a+6+a
9 = 4a+6
9-6 = 4a+6-6
3 = 4a
4a = 3
4a/4 = 3/4
a = 3/4
So the solution is the fraction a = 3/4 (in decimal form 0.75)

Answer:
Step-by-step explanation:
-3*j = -3j
(-3)(-1) = 3
Answer
-3j + 3 Notice the sign change. Be careful about that when signs are used with the distributive property.
N= a1+ (nº 1)dWrite rule for nth term.a13= a1+ (13 º 1)dSubstitute 13 for n.30 = a1+ 1232Substitute for a13and d.12= a1Solve for a1.So, a rule for the nth term is:an= a1+ (nº 1)dWrite general rule.= 12 + (nº 1)32Substitute for a1and d.= 221+ 32
