Answer:
Its 61
Step-by-step explanation:
Following with the extra hint that x = 82.03 m
There are 2 ways to approach the question, but although I prefer to group up x first before plugging value, having that -0.05x^2 to group up is too annoying:
Plug x = 82.03
=> Y = -0.05*(82.03^2) + 4.5*82.03 - 6.5
= -336.446045 + 369.135 - 6.5
= 26.188955 m
Please take the time and understand the answer instead of just looking at the final result.
Also I know the number is very long, but that's the question's fault. <span>¯\_(ツ)_/¯</span>
The system of linear equations x + y = 35 and y = 4x represents the two numbers
<u>Solution:</u>
Given that, The sum of two numbers is 35
The second number, y, is equal to 4 times the first number "x"
We have to find which system of linear equations represent the two numbers? We have two conditions for two variables, so we can obtain two equations, which means a system of equations.
Now, 1st condition ⇒ sum of two numbers is 35 ⇒ x + y = 35
And, 2nd condition ⇒ second number is 4 times the first number ⇒ y = 4x
Hence, the equations, x + y = 35 and y = 4x represents the given numbers.
