Answer:
the solution is (-6, 6)
Step-by-step explanation:
This system, y= -1/2x +3 y= -1/3x +4, can be quickly solved for x by letting y = y:
y= -1/2x +3 = y= -1/3x +4. Then -1/2x + 3 = -1/3x +4. The fractional coefficients should be enclosed inside parentheses:
(-1/2)x + 3 = (-1/3)x +4
Let's remove the fractional coefficients. The LCD is (2)(3) = 6. Multiply all four terms by 6, obtaining:
-3x + 18 = -2x + 24
Combining like terms, we get -6 = x.
Find y: substitute -6 for x in either of the given equations:
y= (-1/2)(-6) +3 = 3 + 3 = 6. So y = 6 when x = -6, and the solution is (-6, 6).
If you are going to eliminate the y term the y must be the same value but different signs
since the second equation has y, a value of 3 you mist make the first one -3 so you will multiply the whole equation by -3
c is the answer
Answer:
2
Step-by-step explanation:
$ 1.55 + $1.65 = $3.11
the budget is $7.95
$7.95 ÷ $3.11 = 2.5 but since you can't get half a milk it's 2
Pls only answer if you know it:) The numbers are 19, 36, 24, 40, 17, 43, 30, 31, 37, 28, 45, 32, 16. What are the first quartile
