Answer:
y = -5/2x + 10
Step-by-step explanation:
Step one: Add -5x to both sides.
5x + 2y + -5x = 20 + -5x
2y = -5x + 20
Step two: Divide both sides by two.
2y/2 = -5x + 20/ 2
y = -5/2x + 10
Hope my answer help.
It will be greater than 9.1 if he multiplied by 10.1
Answer:
70 cabinets in method 1 and 24 cabinets in method 2.
Step-by-step explanation:
Let in method 1 they refinish x cabinets and in method 2 they refinish y cabinets.
Now, given that method 1 and method 2 takes 1 hour and 1.5 hours respectively and the material costs for method 1 and method 2 are $6 and $4 respectively.
If they plan to spend 106 hours in labour and $516 in material for refinishing cabinets, then
x + 1.5y = 106 ...... (1) and
6x + 4y = 516 ....... (2)
Now, solving equations (1) and (2), we get
6 (106 - 1.5y) + 4y = 516
⇒ 5y = 636 - 516
⇒ y = 24 cabinets
From equation (1) x = 106 - 1.5y = 106 - 36 = 70 cabinets. (Answer)
Look at the coefficient of x (the slope).
Is -2 positive or negative?
Since -2 is negative, The slope is negative.
