Answer:
it is .8333333333 and more 3's forever
Step-by-step explanation:
The sale price of 3 bottles of shampoo is 3s and the regular price is 3r. The amount of money you save will only come in when you buy 3. The cost you save is the difference between the regular price and the sale price. The equation is therefore,
c = 3r - 3s
Answer:
x=
−1
/2
y+
3
/4
Step-by-step explanation:
Let's solve for x.
4x+2y=3
Step 1: Add -2y to both sides.
4x+2y+−2y=3+−2y
4x=−2y+3
Step 2: Divide both sides by 4.
4x
/4
=
−2y+3
/4
x=
−1
/2
y+

/4
The system has:
- No solutions for two parallel lines.
- 1 solution for two nonparallel lines.
- Infinite solutions for two equations that describe the same line.
<h3>How to identify the number of solutions for the systems?</h3>
A system of two linear equations is given by:
y = a*x + b
y = c*x + d
1) The system has no solutions when both lines are parallel lines, this happens when both lines have the same slope and different y-intercept.
y = a*x + b
y = a*x + d
2) The system has one solution when the lines have different slopes:
y = a*x + b
y = c*x + d
3) The system has infinite solutions when both equations describe the same line:
y = a*x + b
y = a*x + b
