3x + 4y + 8 = 0
4y = -3x - 8
y = -3/4x - 2....slope here is -3/4. A parallel line will have the same slope.
y = mx + b
slope(m) = -3/4
y int (b) = 4
so ur equation is : y = -3/4x + 4
From the graph, it is obvious that the trend is decreasing from 100 on day 2, to 1 on day 10. So, the answer could either be A or C. The question would be how fast is it decreasing? To illustrate this, let's find the difference of consecutive data:
100 - 26 = 74
26 - 6 = 20
6 - 2=4
2-1=1
It must not be an additive rate because there is no common difference. Let's illustrate if the trend is in multiplicative rate:
100/26 = 3.85
26/6 = 4.33
6/2 = 3
2/1 = 2
More or less, they have a common divider. Hence, the decreasing rate is in multiplicative rate. The answer is A.
Your going to have to draw it out,but just look for the number on your number line and put a point above the number.
Answer:
x= 2, y= 1
Step-by-step explanation:
x= 2y
2x +5y =9
substitute x
2 *2y +5y = 9
4y +5y = 9
9y = 9
y =1
x= 2*y = 2*1= 2
$1 = 3.70 rands
$450 is simply 450 times $1, so multiply the conversion equation above by 450 on both sides.
450 * $1 = 450 * 3.70 rands
$450 = 1665 rands
