16/7 is already in lowest terms. It cannot be further reduced.
You can write this fraction as a decimal by simply dividing the top by the bottom.
So, 16/7 = 2.2857142857
Nothing else can be done here.
3x + 8 = 3x + []
Subtract 3x from both sides.
[] = 8
If you want no values of x, it can be any positive value other than 8.
If you want all values of x, the value must be 8.
If you want only one value of x, it is impossible because both equations have the same slope.
21x + 28 = 156 - 2
21x = 154 - 28
21x/21 = 126/21
X = 6
<u>Answer</u>
Part 1: l = -1.665g
Part 2: Max-mum the spring can support.
Part 3: The spring constant.
<u>Explanation</u>
Gradient is also called the slope.
Slope = (change in y) /(change in x)
= (60 -40)/(6.7 - 40)
= 20 / -33.3
= - 0.600600601
Since the graph is a straight line, the equation would be,
m ∝ l
m = kl Where K is the constant.
<u>g</u> = -0.60l
l = -1.665g
<u>Part 2</u>
The Y-intercept represent the mix-mum weight the spring can support.
<u>part 3</u>
The slope in this case represent the spring constant.
