Answer:
- The relationship between the number of months after the first year and the amount on the remaining card is linear and inverse ( Which meant that ,when the number of months after the first year increases , the amount on the remaining car decreases , in a linear way ) .
- The Independent variable is the <u>numbers of months after the first year .</u>
- The Dependent variable is the<u> </u><u>amount on the remaining card , Bcoz this amount depends on the time it has passed since the first year , ( which is our independent variable!).</u>
- <u>If </u><u>we </u><u>call </u><u>"</u><u>Y"</u><u> </u><u>our </u><u>dependent</u><u> </u><u>variables</u><u> </u><u>and </u><u>"</u><u>X"</u><u> </u><u>our </u><u>Independent</u><u> </u><u>variable</u><u> </u><u>,</u><u> </u><u>This </u><u>relationship</u><u> </u><u>can </u><u>be </u><u>written</u><u> </u><u>as </u><u>Y=</u><u> </u><u>2</u><u>5</u><u> </u><u>-</u><u> </u><u>2</u><u>.</u><u>5</u><u>x</u><u>.</u>
- <u>If </u><u>no </u><u>months </u><u>had </u><u>passed </u><u>since </u><u>the </u><u>first</u><u> </u><u>year,</u><u> </u><u>then </u><u>x=</u><u> </u><u>0</u><u> </u><u>and </u><u>the </u><u>amount</u><u> </u><u>in </u><u>the </u><u>card </u><u>equals </u><u>$</u><u>2</u><u>5</u><u> </u><u>,</u><u> </u><u>While </u><u>if </u><u>one </u><u>month </u><u>has </u><u>passed </u><u>since </u><u>the </u><u>first </u><u>year </u><u>x=</u><u> </u><u>1</u><u> </u><u>and </u><u>y=</u><u> </u><u>2</u><u>2</u><u>.</u><u>5</u><u> </u><u>(</u><u> </u><u>The </u><u>amount</u><u> </u><u>in </u><u>the </u><u>card </u><u>in </u><u>this </u><u>case </u><u>is </u><u>$</u><u>2</u><u>2</u><u>.</u><u>5</u><u> </u><u>.</u>

Answer:
9x - 36 = 10
Step-by-step explanation:
3/4 x - 3 = 5/6
The least common multiple of 4 and 6 is 12.
Multiply both sides of the equation by 12.
12 * (3/4 x - 3) = 12 * 5/6
12 * 3/4 x - 12 * 3 = 10
9x - 36 = 10
Answer:
1/3
Step-by-step explanation:
The slope of the line is found by
m = (y2-y1)/(x2-x1)
we have two point ( 0,0) and ( 3,1)
= ( 1-0)/( 3-0)
= 1/3
Answer: 29.2cm
Step-by-step explanation: perimeter of parallelogram; 2(a + b) where a = base, b = altitude
a = 8cm
b = 6.6cm
Perimeter = 2(8 + 6.6) = 2(14.6)
Perimeter = 29.2cm
