Answer:
d. The common ratio is 1.1
Step-by-step explanation:
To see if the data has a common ratio or common difference, we have to see if the division between them is equal(common ratio), or if the difference between them is equal(common difference).
In this case, since 
, it has a common ratio.
To find it, we divide consecutive terms. For example:
So the correct answer is:
d. The common ratio is 1.1
Factor the following:
x^2 - 16 x + 63
The factors of 63 that sum to -16 are -7 and -9. So, x^2 - 16 x + 63 = (x - 7) (x - 9):
Answer: (x - 7) (x - 9)
Answer:
Small number = 19
Larger no. = 3(19)+14 = 71
Step-by-step explanation:
x + 3x + 14 = 90
4x + 14 = 90
4x = 90 - 14
x = 76 / 4 = 19
Answer:
In the picture.
Step-by-step explanation:
I hope that it's a clear solution.
Answer:
See below
Step-by-step explanation:
5x + y = 9 re-arrange to y = 9-5x
use this value of 'y' in the second equation:
10x - 7(9-5x) = - 18
solve for x = 1
sub in this value of 'x' into one of the equations to compute 'y'
5 (1) + y = 9
y = 4
