Answer: ×=1.29
Step-by-step explanation:
Open the brackets
-12x +9 +5x
-12x+5x=-9
-7x= -9
Divide both sides by -7
X=9/7 =1.29
Answer:
25 rounds
Step-by-step explanation:
Let
x -----> the number of rounds of golf
y ---> total charges to play
The linear equation in slope intercept form is equal to
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
where
m is the slope or unit rate
b is the y-intercept or initial value
<em>Membership</em>
----> equation A
The slope is m=$35 per round
The y-intercept b=$500 (annual membership fee)
<em>Non-Membership</em>
----> equation B
The slope is m=$55 per round
The y-intercept b=$0
Equate equation A and equation B
![55x=35x+500](https://tex.z-dn.net/?f=55x%3D35x%2B500)
solve for x
![55x-35x=500](https://tex.z-dn.net/?f=55x-35x%3D500)
![20x=500](https://tex.z-dn.net/?f=20x%3D500)
![x=25\ rounds](https://tex.z-dn.net/?f=x%3D25%5C%20rounds)
For x=25 rounds the cost to be the same with and without a membership
Answer:
-36/7 or -5.14287
Step-by-step explanation:
so I would get rid of parentheses you do not need them
=
(because when two negative come before two numbers like -x-y they are being added but negative is present to the result of the sum, when one negative sign comes after a number and the other negative sign comes before a number, like x--y they are being added as well but negative is not present to the result of the sum)
-36/7=-5.1428
hope this helps!
Answer:
4/8, -0.5, 0.75
