Answer:</h2>
The number of kilograms a 19 m beam can support is:
378.9474 kg
<h2>
Step-by-step explanation:</h2>
It is given that:
The weight W that a horizontal beam can support varies inversely as the length L of the beam.
Let k denote the constant.
This means that the weight W and Length L is related as:
Suppose that an 8 dash m beam can support 900 kg.
This means that L=8 and W=900
Then,
Now , we are asked to find the value of W when L= 19
i.e.
Answer:
(7, 5) no
(-6, -3) yes
(-5, 2) no
(1, -4) no
Step-by-step explanation:
For this question we have to input the x and y values into the equation: 2x - 9y = 15
For (7, 5) we would get 14 - 45 = 15 which is false so it is not a solution.
For (-6, -3) we would get -12 + 27 = 15 which is true so it is a solution.
For (-5, 2) we would get -10 - 18 = 15 which is false so it is not a solution.
For (1, -4) we would get 2 + 36 = 15 which is false so it is not a solution.
