Answer:
3 and 4
Step-by-step explanation:
no, this is false. 1 is greater than 12/20.
Answer:
The slope is -2.
Step-by-step explanation:
The slope formula is (y1-y2)/(x1-x2)
or change in y / change in x.
First, you plug in your numbers. I will use (2, 7) as (x1, y1)
(1-7)/(5-2)
Next, simplify.
(-6)/(3)
or
-2
And that's your slope!
Answer:
x+ (x+1) = 55
27, 28
Step-by-step explanation:
Let x = first number
x+1 is the next consecutive number
x+ (x+1) = 55
Combine like terms
2x+1 = 55
Subtract 1 from each side
2x+1-1 = 55-1
2x = 54
Divide by 2
2x/2 = 54/2
x = 27
The numbers are 27 and 28
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
