Answer:
no >:)
Step-by-step explanation:
The formula for the sum of n terms in an arithmetic progression is:
S = n/2 * (2a + (n-1)d)
Here, the common difference, d, is 8 and the first term, a, is 1. Substituting these into the formula, we get:
S = n/2 * (2*1 + 8(n - 1))
S = n + 4n² - 4n
S = 4n² - 3n
The answer is A.
Answer:
y=4x+7
Step-by-step
(-2,1) and (1,-11)
1)Rule you should use is run over rise aka slope
y²-y^1=
x^2-x^1=
(-11)-1=12
1-(-2)=3
12/3=4
slope =4
2)Rule of point slope intercept
y - y1 = m(x - x1)
y+1=4(x+2)
y+1=4x+8
-1 -1
y=4x+7
D) People per hour, because the dependent quantity is the people
The dependent quantity is the quantity that relies on other variables of the situation. Therefore, the hours it takes relies on the amount of people that come into the theme park. People will continuously come into the park, they do not depend on anything. This is why it can not be C.
To solve for X in this equation, you would subtract both sides by 14 because our goal is to get X on its own. If we write it out, we see that
X + 14 - 14 = 56 - 14
X=42
Because we have a positive 14, a negative 14 will average out to be 0, but what you do to one side, you must do to the other.
