Answer:
The answer is Graph III.
Step-by-step explanation:
Given that the linear equation is y = mx + c where m represents gradient and c is y-intercept.So firstly, we have to make y the subject :
![3x - 36 + 2y = 0](https://tex.z-dn.net/?f=3x%20%20-%2036%20%2B%202y%20%3D%200)
![2y = - 3x + 36](https://tex.z-dn.net/?f=2y%20%3D%20%20-%203x%20%2B%2036)
![y = - \frac{3}{2} x + 18](https://tex.z-dn.net/?f=y%20%3D%20%20-%20%20%5Cfrac%7B3%7D%7B2%7D%20x%20%2B%2018)
Next, by looking at the graph, we know that the line has a negative gradient and touches y-axis at 18 which suits the equation.
The answer is
A,B
Explanation
Because the square root of A is 4 and the square root of B is 5
The square root of C is 11.1803398875 and the square root of D is 14.6969384567.
Therefore A,B are perfect squares
To divide fractions, we do Keep, Change, Flip. Keep means that we keep the first fraction the same ( which is 8/1). Then for Change, we change the division sign to a multiplication sign. After that we Flip the second fraction itś reciprocal (or multiplicative inverse).
So your equation would be:
8/1 x 3/1 which equals 24
sorry if it is wronged the answer is D
Answer:
9 runners
Step-by-step explanation:
Number of runners who started race = 45
Fraction that dropped off in the first half =. 2/3
Fraction of the remaining that dropped of in the second half = 2/5
Number of runners who dropped off in the first half :
(2/3) * 45 = (2 * 45) / 3 = 90 /3 = 30 runners
Runners left = (45 - 30) = 15
Number who dropped off in the second half :
(2/5) * 15 = (2 * 15) / 5 = 30 /5 = 6 runners
Number of runners who finished the race :
(15 - 6) = 9 runners
