2x^2 + x -3 can be factorised
<span>[2x + 3][x - 1] </span>
<span>As length times width = area </span>
<span>one possible set of measurements are </span>
<span>length = [2x + 3] </span>
<span>width = [x-1] </span>
that's it's formulae for the appropriate root
Answer:
3i square root 2
Step-by-step explanation:
Answer:
The answer to your question is 12x + 24y ≤ 120
Step-by-step explanation:
Data
12 min oil change and variable x
24 minutes tire change and variable y
total time = 120 min
Process
1.- Calculate the number of oil changes
12x
2.- Calculate the number of tire changes
24y
3.- Calculate the total number of changes
12x + 24y
4.- Write the inequality
12x + 24y ≤ 120
Use ≤ to mention that 120 is been considered.
Answer:
1. slope= 3/4x Y-intercept= 7
2. slope= 5x Y-intercept=8
3. slope= -2x Y-intercept=0
4. slope= 0 Y-intercept=12
*the table ones are difficult to type out but sorry if it doesnt make sense*
5. X Y=3x+4. Y
0 y=3(0)+4 4
1 y=3(1)+4 7
2 y=3(2)+4 10
3 y=3(3)+4 13
4 y=3(4)+4 16
6. X y=1/2x-1. Y
-2 y=1/2(-2)-1 -2
1 y=1/2(1)-1 1.5
4 y=1/2(4)-1 2
6 y=1/2(6)-1 3
9 y=1/2(9)-1 3.5
7. X. Y=5-2x Y
0 y=5-2(0) 5
1 y=5-2(1) 3
2 y=5-2(2) 1
3 y=5-2(3) -1
4 y=5-2(4) -3
I believe you need the graph for the last 3
