Answer:
The graphs are posted.
Step-by-step explanation:
the method to solve such inequalities is assume the line and then draw the line then search for the inequality
The y < 0.5x-3
First plot the line y=0.5x-3
Now all the values of y which are below the line satisfies the inequality.
similarly for the second question x+y ≥ 5.
Now assume the line x+y=5
All the values of (x , y) above the line satisfies the equation including the points on the line .
Answer:
40 cubic inches
Step-by-step explanation:
The Formula for Volume: Length x Width x Height (L x W x H)
4 times 2 times 5 = 40
Answer:
6
Step-by-step explanation:
The answer is 6 because there is three other couples and so Barbie would have shaken each couples hand and in a couple there are two people so that would be two handshakes per couple minus Kens hand.
9+10=19
proof, 9=1 plus 1 9 times (to lazy to write it out)
10=1 plus 1 10 times(to lazy)
so 1+1+1+1+1+1+1+1+1 + 1+1+1+1+1+1+1+1+1+<span>1 = 19</span>
Answer:
9 inches
Step-by-step explanation:
Do the question algebraically, represented by this equation:
let x be the shorter piece
x + (x + 8) = 26 (longer piece is 8 units longer)
Remove brackets
x + x + 8 = 26 Combine like terms
2x + 8 = 26 Start isolating "x"
2x + 8 - 8 = 26 - 8 Subtract 8 from both sides
2x = 18
2x/2 = 18/2 Divide both sides by 2
x = 9 shorter piece
The shorter piece would be 9 inches.
If you needed the longer piece too:
longer piece = x + 8
x + 8
= 9 + 8
= 17
The longer piece would be 17 inches.
Check your answer:
Longer + Shorter = 26 Substitute the lengths
17 + 9 = 26 Add
26 = 26 same number
LS = RS left side equals right side
The answer is correct.
