Answer:
Picture 3
Step-by-step explanation:
The easiest method is to see if (0,0) is the solution.
1. <em>The line y ≤ -3x + 2 is the line pointing down, and y - x ≥ 2 is the line pointing up</em>, since negative slopes go bottom-right.
2. y - x ≥ 2 --> plug in numbers: 0 - 0 ≥ 2 --> Not true --> the line pointing up's shading will go up, to avoid (0,0) --> <em>Picture 3 is right</em>.
3 (not needed in this situation). y ≤ -3x + 2 --> 0 ≤ 0 + 2 --> True --> The line pointing bottom right has (0,0) --> <em>Picture 2 or 3 is right</em>.
The overlap of possible answers is picture 3.
Answer:
m∠RPQ = 8°
Step-by-step explanation:
m∠QRS = 4x - 15
m∠RPQ = x + 1
m∠PQR = x - 2
m∠QRS is exterior angle and m∠RPQ and m∠PQr are opposite interior angles to m∠QRS
m∠QRS = m∠RPQ + m∠PQR {Exterior angle property of triangle}
4x - 15 = x +1 + x - 2
4x - 15 = x + x + 1-2 {Combine like terms}
4x - 15 = 2x - 1 {Subtract 2x from both sides}
4x - 2x - 15 = - 1
2x - 15 = - 1 {Add 15 to both sides}
2x = -1 + 15
2x = 14 {Divide both sides by 2}
x = 14/2
x = 7
m∠RPQ = x + 1 = 7 + 1 = 8°
Answer:
The 8 pounds bag
Step-by-step explanation:
Case 1 :
a pound cost 4/3
case 2 :
a pound cost 9/8
4×8 > 9×3
then
Therefore the 8 pound bag costs less
In money if you have £6.25 it is easier to write it in decimals
If you are measuring something e.g. 10.3cm long no one writes it 10 3/10 cm
