Look for a common number in all the terms
6(2a+3b-c)
Answer:
(7,2)
Step-by-step explanation:
x + y = 9 + 2x - 3y = 8 is really two equations, and you should show this by separating x + y = 9 from 2x - 3y = 8 through the use of a comma, or the word "and," or through writing only one equation per line.
Here you have the system of linear equations
x + y = 9
2x - 3y = 8.
Let's solve this system by elimination. Mult. the 1st eqn by 3, obtaining the system
3x + 3y = 27
2x - 3y = 8
-------------------
5x = 35, so that x = 7. Subbing 7 for x in x + y = 9, we get 7 + y = 9, indicating that y = 2.
Thus, the solution to this system of equations is (7,2).
The volume is twice that of the cube of width, so the width of the original prism is
.. ∛(16 cm³/2) = 2 cm
Length = 4 cm
Width = 2 cm
Height = 2 cm
-2x + (1/2)y = 18
(1/2)y = 2x + 18
y/2 = 2x + 18
y = 2*(2x + 18)
y = 2*2x + 2*18
y = 4x + 36
The x intercept is the value of x, when the y value is 0.
0 = 4x + 36
0 - 4x = 36
-4x = 36
x = 36/-4
x = -9
The x intercept is -9
I hope this helps.
