Answers:
first term = 37
second term = 46
third term = 55
fourth term = 64
==========================================
Explanation:
Start at 37. Add 9 to this term to get the second term. Add 9 to that result to get the next term, and so on.
first term = 37
second term = 37+9 = 46
third term = 46+9 = 55
fourth term = 55+9 = 64
-----------
The nth term formula is
a(n) = 9n+28
It can be found by plugging a = 37 and d = 9 into the general form
a(n) = a + d*(n-1)
(f + g)(x) = f(x) + g(x)
(f + g)(x) = 3x + 5 + x^2 = x^2 + 3x + 5
Answer: Choice D
3x - y = -4
3x - (-10) = -4 Substitute
3x + 10 = -4 Simplify
3x = -14 Separate numbers and variables
x = -14/3 Divide
2x - y = - 10
2x - (-10) = -10 Substitute
2x + 10 = -10 Simplify
2x = -20 Separate numbers and variables
x = -10 Divide
The total number of possible combinations to make a three digit number is 60
<u>Explanation:</u>
Given:
Five numbers are there = 1, 2, 3, 4, 5
We have to form three digit number
The number should not be repeated
Consider 3 dashes for 3 digits : ___ ___ ___
The first dash can be occupied by any 5 digits.
The second dash can be occupied by 4 digits
The third dash can be occupied by 3 digits
Thus, number of possible combinations to make a three digit number is
= 5 X 4 X 3
= 60
Therefore, total number of possible combinations to make a three digit number is 60
Hi I don’t know if this is right but I got that k is equal to 4 I got that because if you do
4 times 3/4 you get 12/4 that is equal to 3.
Now you have k + 3=7 you move 3 to the other side and make it negative
K= 7-3
K=4
Hope this helped!
