Answer:
Step-by-step explanation:
We need to solve the system of equations here.
Our main objective is to remove one of the variables.
To do so we can multiply the second equation by 2 and get 2x+4y=-8
Then we can subtract our new equation from the earlier one and get -5y=21
thus we know y=-21/5=-4.2
we plug that back into the equation and find x
2x-(-4.2*3)=13
2x=25.6
x= 12.8
so the solution is 12.8,-4.2

Aaliyah is taking a multiple choice test with a total of 20 points available. Each question is worth exactly 2 points. What would be Aaliyah's test score (out of 20) if she got 3 questions wrong? What would be her score if she got x x questions wrong?
Answer by JKismyhusbandbae:
Explanation: The slope is 5/3 but it every-time it goes up by 3.
The path of the ball is the diagonal of the rectangle.
You can use the Pythagorean theorem.
a^2 + b^2 = c^2
64^2 + 48^2 = c^2
4096 + 2304 = c^3
6400 = c^2
c = 80
Answer: 80 meters
