Answer:
option D. Neither
Step-by-step explanation:
y-4=7(x-6)
using (5,4):
4-4=7(5-6)
0=7(-1)
0=-7
using (6,5):
5-4=7(6-6)
1=7(0)
1=0
so option D is the answer
Answer:
The common ratio of a geometric series is \dfrac14
4
1
start fraction, 1, divided by, 4, end fraction and the sum of the first 4 terms is 170
The first term is 128
Step-by-step explanation:
The common ratio of the geometric series is given as:
The sum of the first 4 term is 170.
The sum of first n terms of a geometric sequence is given b;
common ratio, n=4 and equate to 170.
Answer:
A. 432=18x
B. 22-see explanation
C. 24
D. See if your rounded answer and the actual answer are close.
Step-by-step explanation:
A. He buys a new phone for $432, and pays each month. We will use the variable x, and "x" will represent how many months he pays. It says that he pays $18 per month, so the equation would be 432=18x.
B. We need to isolate x, and to do this we have to divide 432 by 18. To approximate this answer, round 432 to 440 and 18 to 20. Now, divide 440 by 20. We get 22, so this will be the estimation.
C. Divide 432 by 18. We get 24.
E. You can see if it is reasonable if they are close in value.
Hi.
Please note that I haven't done much algebra.
4 more = 4 +
Twice as many than the runner up means 2 times the amount they ate (a variable) = 2n
So far we have 4 + 2n
Since it's an equation, we are going to know what it equals. In the problem, we find out that it's 11. So the equation looks like this:
4 + 2n = 11
If this didn't work out, please let me know.
