Q= -1. I did this problem by elimination, by multiplying the first one by -4 and the second by 3, to cancel out the p. I ended up with -7q=7. I divided both sides by -7, and got q=-1.

Shtirlitz [24]
Firstly, you would subtract 7 from both sides, leaving you with 3m=21. You would then divide by three in order to be left with total value of m. 3m divided by 3 is m. 21 divided by 3 is 7. Therefore m=7 :)

Is (5,0) a solution of the graphed inequality?
AURORKA [14]

Answer:

Yes

Step-by-step explanation:

5,0 is a solution to the graphed inequality as it lies on the edge of the shaded area. Because the line is solid rather than dotted/dashed this means that all answers on the line will be included in the solutions. This is a graph for an inequality with one of these symbols ≤ ≥.

In the sequence 0, 1, 1, 3, 6, 9, 27, ..., the first term is 0. Subsequent terms are produced by alternately adding and multiply
salantis [7]

Answer:

645

Step-by-step explanation:

Let's first try and write our series up to 125 before we know the next number.

Well continue from the given series.

0, 1, 1, 3, 6, 9, 27

The next number= 27+4= 31 , then 31 *4 = 124

The next after 124 = 124+5= 129, then 129*5 = 645

So actually the question was supposed to be the term greater than 124 because 125 does not exist in the series.

The number is 645
