First, we need to find out what -3 + 7 is. -3 + 7 = 4. The reason that we got 4 is because we started at -3 and went forward 7 times. When we went forward 7 times, we landed on 4. Next, we need to find out out what -10 - 2 is. -10 - 2 is -12. The reason we got -12 is simple. There is a little method that I like to call keep,change, opposite. First, we keep -10 as is. Next, we switch - to a + sign. Finally, what is the opposite of 2. You guessed it, it's -2. When you put all the pieces together, it is -10 + (-2)= -12. But we are not done yet, four is greater than -12 because -12 is a negative number while 4 is a positive. So, the answer would be "C"
Hope this helped
Answer:
-1
Step-by-step explanation:
anything to the power of zero is always going to be 1 or -1
The 12th term = a + 11d where a is the first term and d is the common difference
a + 11d = 74
The first three terms are a, a + d, a + 2d
a + (a + d) + (a + 2d) = 42
3a + 3d = 42
a + d = 42 / 3 = 14
By subtracting this equation from the T12 equation
(a + 11d) - (a + d) = 74 - 14
10d = 60
d = 6 (the common difference = 6)
a + 6 = 14
a = 14 - 6 = 8 (the first term = 8)
S(n) = n/2 x (2a + (n-1)d)
S(10) = 10/2 x (2x8 + (10-1)x6)
S(10) = 5 x (16 + 54) = 5 x 70 = 350
Answer:
-4
Step-by-step explanation:
You are trying to find which t value gives you the answer of 13. Set the equation equal to 13 and solve for t.
-2t + 5 = 13
-2t + 5 - 5 = 13 - 5
-2t = 8
-2t/-2 = 8/-2
t = -4
