The formula for the sum of geometric series = a (1 - r^n) / 1 - r
when it will be an infinite geometric series. the term r^n will equal to zero because and number < 1 that is raise to the power infinity the answer is zero that is why in a infinite geometric series, sum = a / 1 - r.
if the r < 1 then there will be no numerical answer because the sum will be infinity. that is why r < 1 to have a sum
Equation of a line is given by y - y1 = m(x - x1); where m is the slope.
y - (-2) = 4(x - 3)
y + 2 = 4(x - 3)
Answer:
the first mistake was in step 2
Step-by-step explanation: she should not have moved the y to the other side first, she should have moved the other numbers to get one of the y's alone
Answer:
x=-36
Step-by-step explanation:
Add the 7/2x +1/2x to be 8/2x which means that it'll be 4x=18=9/2
then subtract 9/2x on both sides so itll be
-9/2x -9/2x
because if you do 8/2-9/2 it's -1/2
then multiply the reciprocal to both sides so
which then cancels out -1/2 and makes it
x=-36
Answer:
a=1,b=3,c=10
Step-by-step explanation:
a= the number with the highest power, in this case it is x^2. Therefore, a=1.
b= the number with the second number, the one that has an x. Therefore, b=3.
c=the last number, the one with no variable. therefore, c=10
