The line needs to be 8.06 m long
Explanation
Given that the ladder is 7 feet tall and the bottom of the slide should be 4 m away from the ladder.
The ladder,slide and the ground connecting them makes the sides of a right angled triangle with ladder as the height and ground as the base.
base=4m
height=7m
hypotenuse can be determined using pythagoras law
![b^{2} +h^{2} =H^{2} \\x^{2} 4^{2}+ 7^{2}= H^{2} \\16+49=H^{2} \\H=\sqrt{65} \\=8.06 m](https://tex.z-dn.net/?f=b%5E%7B2%7D%20%2Bh%5E%7B2%7D%20%3DH%5E%7B2%7D%20%5C%5Cx%5E%7B2%7D%204%5E%7B2%7D%2B%207%5E%7B2%7D%3D%20H%5E%7B2%7D%20%5C%5C16%2B49%3DH%5E%7B2%7D%20%5C%5CH%3D%5Csqrt%7B65%7D%20%5C%5C%3D8.06%20m)

Answer:
true
Step-by-step explanation:
The equation 11x + 10y = 32 is a linear equation, and the solution to the linear equation 11x + 10y = 32 is ![y = \frac{32 - 11x}{10}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B32%20-%2011x%7D%7B10%7D)
<h3>How to solve the equation?</h3>
The equation is given as:
11x + 10y = 32
Subtract 11x from both sides
10y = 32 - 11x
Divide both sides by 10
![y = \frac{32 - 11x}{10}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B32%20-%2011x%7D%7B10%7D)
Hence, the solution to the linear equation 11x + 10y = 32 is ![y = \frac{32 - 11x}{10}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B32%20-%2011x%7D%7B10%7D)
