Well we want to pull out the important values here to determine our expression which in this case is $2 and $.50. Since the fixed cost is 2 and there is .50 per kilometer. We can say that .50(m)+2 is our expression. Hope this helps! I apologize if you were looking for something else in advance.

$2 + $0.5K = 0
where $2 is contant and
K is the variable term in form of killometers

X-20 = y+20<br>2Y - 44 = X + 22<br>

nordsb [41]

X-20 = Y+20........ X-Y = 20+20........

X-Y = 40

AND

2Y-44=X+22............. Y-X= 44+22

Y-X=66

NOW, LET'S FIND X AND Y FROM THESE TWO EQUATIONS....

X-Y =40

Y-X= 66

IF WE COLLECT ....... 2Y = 106 AND Y = 53

THEN, USE Y IN ANY EQUATIONS FOR FINDING X

X-53 = 40 ..... X= 53+40 .......... X= 93

X= 93

Y=53

Find the gradients for line A and B.<br><br> See pic attached

pogonyaev

Gradient is the difference between the y-axis and the x-axis
Gradient = y2-y1/x2-x1
Choose any two point making a triangle
Line B (0,8) (4,0)
This makes a triangle please go look at the graph once again! The the triangle should not have half squares but full!
Line A (5,14)(2,2)
Now plug in the variable
The difference between the Y and X
Line B 0-8/4-0
Line B gradient =-2
Line A 2-14/2-5
Line A gradient = +4

Finalized answer
Line B gradient = -2
Line A gradient = +4

What is the common ratio between successive terms in the sequence 1.5, 1.2, 0.96, 0.768

Pani-rosa [81]

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.
