This means that x is equal to -3 and y is equal to 8. For example, if you had f(x)=-3x-1 and plugged -3 into x, you would get the y-value of 8.

Solve the equation <br><br> 3x-1/2y=2
poizon [28]

Answer:

Step-by-step explanation:

Without a second equation relating x and y, we can solve 3x - 1/2y = 2 ONLY for x in terms of y or for y in terms of x:

x in terms of y:    Multiply all three terms of 3x - 1/2y = 2 by 2, to eliminate the fraction:  6x - y = 4.  Now add y to both sides to isolate 6x:  6x = 4 + y.

Last, divide both sides by 6 to isolate x:

x = (4 + y)/6

y in terms of x:    

y = 6x - 4

If you want a numerical solution, please provide another equation in x and y and solve the resulting system.

The price of a cup of coffee was $2.75 yesterday. Today, the price fell to $2.40. Find the percentage decrease. Round your answe
Fed [463]

Answer: (2.75-2.40)/(2.75) * 100 [Before rounding to the nearest tenth]

Step-by-step explanation:

Formula for percentage decrease = (old-new)/(old) * 100

so substituting in, you get (2.75-2.40)/(2.75) * 100

From here, you can just plug this into a calculator (don't have on me rn)
