Answer:
Elimination (multiplication and subtraction)
There is 1 solution
Step-by-step explanation:
The only way to solve this system of equations is by elimination (multiplication). Let's say that we want to cancel out the x. You multiply the first equation by 5 and you multiply the second equation by 2.
Your equations now are:
10x-5y=55 and 10x+6y=-22
You can subtract these equations to get -11y = 77.
Now that we know that y = -7, we can substitute y in to solve x.
10x-5(-7) = 55
10x=20
x=2
Final answer (2,-7)
1. A~ 2r^2 + 15r-50
2. B~ k^2 - 4k+3
Answer:
For the multiple choice question, choose the correct answer from the choices below. a can of soda is in the shape of a cylinder. the formula for the volume of a cylinder is v=πr2hv=πr2hwhere r is the radius of the can and h is the height of the can. if a can of soda is 4.83 inches high and has a radius of 1.3 inches, what is the volume (in square inches) of a can of soda? use 3.14 as an estimation for pi and round your answer to one decimal place.
