x should equal -2 and y should equal -3 to solve this i multiplied the first equation by 2 then got rid of the 4y and -4y then i added the 14x to the 9 equaling 23x and added the -40 to the -6 which became 23x=-46 i solved this getting -s for x, then i plugged that into the equations to get y which was -3
Closest would be 8 43/200
Answer:
Daniel
Step-by-step explanation:
Daniel ran 5000/40=500=4=125 meters in 1 minutes
Andy ran 4550/37=122.9729... some less than 123 meters in second
Daniel was faster than Andy
Answer:
6 possible integers
Step-by-step explanation:
Given
A decreasing geometric sequence

Required
Determine the possible integer values of m
Assume the first term of the sequence to be positive integer x;
The next sequence will be 
The next will be; 
The nth term will be 
For each of the successive terms to be less than the previous term;
then
must be a proper fraction;
This implies that:

<em>Where 7 is the denominator</em>
<em>The sets of </em>
<em> is </em>
<em> and their are 6 items in this set</em>
<em>Hence, there are 6 possible integer</em>
Answer:
I don't know what you're answer is supposed to look like but if you're creating an equation it should be this...
Step-by-step explanation:
( 4 · √x ) - ( 8 · √x )
