Answer:
x = -1
Step-by-step explanation:
2x - 7 = 9x
Subtract 2x from both sides: -7 = 7x
Divide both sides by 7: -1 = x
Now plug in 7 for every value of x in the original equation to make sure you are correct:
2(-1) - 7 = 9(-1)
-2 - 7 = -9
-9 = -9
I hope this helps!
Answer:
The 50th term is 288.
Step-by-step explanation:
A sequence that each term is related with the prior by a sum of a constant ratio is called a arithmetic progression, the sequence in this problem is one of those. In order to calculate the nth term of a setence like that we need to use the following formula:
an = a1 + (n-1)*r
Where an is the nth term, a1 is the first term, n is the position of the term in the sequence and r is the ratio between the numbers. In this case:
a50 = -6 + (50 - 1)*6
a50 = -6 + 49*6
a50 = -6 + 294
a50 = 288
The 50th term is 288.
Answer:
x³ + 5x + c
Step-by-step explanation:
Using the power rule
∫ a dx =
Thus
∫ x² + 5 dx
= x³ + 5x + c ← c is the constant of integration
