-7-1/2-5 because to solve, you do y2-y1/x2-x1
So you get -6/-3, which equals 2
SLOPE IS 2

Answer:
To determine the common ratio of a geometric sequence. You just need to divide any two consecutive terms on it. You can see below that all of them have the same quotient.
1.2 / 1.5 = 0.8
0.96 / 1.2 = 0.8
0.768 / 0.96 = 0.8
.
Decimal form = 0.8
Fraction form = 4/5
.
Check:
1.5 x 0.8 = 1.2
1.5 x 4/5 = 6/5 = 1 1/5 = 1.2
Therefore, the common ratio between successive terms in the sequence? 1.5, 1.2, 0.96, 0.768 is 0.8 or 4/5.
Answer:
x = 200
y = 100
Step-by-step explanation:
20x + 30y = 7000 Divide by 10
15x + 35y = 6500 Divide by 5
===============
It helps if you break down both equations to something simpler. It looks like not always.
(2x + 3y = 700) Multiply by 3
(3x + 7y = 1300) Multiply by 2
==================
6x + 9y = 2100
<u>6x + 14y =2600</u> Subtract
-5y = - 500 Divide by -5
-5y/-5 = -500/-5
y = 100
2x + 3y = 700 substitute y = 100
2x+ 3*100 = 700 Combine
2x + 300 = 700 Subtract 300 from both sides.
2x = 700 - 300
2x = 400
x = 400/2
x = 200
===================
Hockey check
15x + 35y = 6500
15*200 + 35*100 = 6500
3000 + 3500 = 6500 Just as it should.
