Answer:
1. No solution
2. Infinite solutions
Step-by-step explanation:
1. To solve the system, set the equations equal to each other and solve for x.
2x - 5 = 2x + 7
-5 = 7
This is a false statement. This means there is no solution.
2. To solve the system, graph each equation.
y = -3/4 x - 5/2 has a y-intercept -5/2 and slope -3/4.
3x + 4y = -10 converts to y = -3/4x -5/2.
This graphs as the exact same line. This system has infinite solutions.
Sorry if my handwriting sloppy.
I showed all of it step by step.
Let the ratio between 2 of them be a/b. The volume of the larger one is x (ft^3)
<span>(a/b)^2 = 20/45 = 4/9 ---> a/b = 2/3 </span>
<span>(a/b)^3 = 8/x </span>
<span>8/x = (2/3)^3 = 8/27 ---> x = 27 (ft^3) </span>
<u>Answer:</u>
(2, 7) or (-6, 1)
<u>Step-by-step explanation:</u>
We are given two equations:
; and

Since y is the subject for both the equations so we can put the values of y equal to each other to get:



Factorizing the expression to get:



Putting x = 2 and x = -6 in any of the equations to get the values of y:



and


Therefore, solution to these equation is (2, 7) or (-6, 1).
