Answer:
- infinitely many
- one solution
- no solution
- one solution
Step-by-step explanation:
1. 4x−x=2x+x
Simplifies to 3x = 3x, which is true for all values of x. Hence there are infinitely many solutions.
___
2. 2x+1=5
True only for x=2; one solution.
___
3. 4x+2=5x−x+4
Simplifies to ...
4x +2 = 4x +4
2 = 4 . . . . . . . not true for any value of x; no solution.
___
4. 2(x+4)=4(x+2)
Simplifies to ...
2x +8 = 4x +8
0= 2x . . . . . . . . . subtract 2x+8
True only for x=0; one solution.
Answer:
Step-by-step explanation:
<u>Slope-intercept form: </u>
<u>Use two of the ordered pairs and find the slope:</u>
- m = (1-2)/(0-(-2)) = -1/2
<u>y-intercept is 1 as point (0, 1) is given in the table:</u>
<u>The line is:</u>
Answer:
4 IS $1
8 IS $2
12 IS $3
16 IS $4
Step-by-step explanation:
On the coordinate plane it would be a number on the top left and point at a bottom number, the top left is the first number and on the bottom is the last number. Hope that helped!
A number line is a line that extends infinitely in both directions (marked by arrows) that shows a range of numbers with a consistent distance between increments.
- Draw a line
- Draw arrows on both sides pointing out
- Write the minimum and maximum values on the left and right side repectively
- Add appropriate increments with equal distances on the number line
