Answer:
5*-5x*-7=
Step-by-step explanation:
*=multiply
5y = 135....divide both sides by 5
y = 135 / 5
y = 27 <==
Answer:
AB = sqrt 74 = 8.602
Step-by-step explanation:
simple:
a^2+b^2=c^2
5^2+7^2=74
ab=sqrt 74
Formula :
Distance between two points = √(xB−xA)2+(yB−yA)2(xB-xA)2+(yB-yA)2
Solution :
Distance between two points = √(8−3)2+(2−9)2(8-3)2+(2-9)2
= √52+(−7)252+(-7)2
= √25+4925+49
= √7474 = 8.6023
Distance between points (3, 9) and (8, 2) is 8.6023
Answer:
The range of rental car rates that would be cheaper for Jamal than the taxi service is given by,
A ={x| 0 ≤ x < 26} [where x is in dollar]
Step-by-step explanation:
Let, the car rental rate be $ x per day .
Jamal's trip will last for 4 day.
He expects to pay $ 24 for gas (if he rents the car)
He expects a taxi service would cost about $ 128
So, for the rental car option to be cheaper than the taxi option, the following inequality must follow,
128 > 24 + 4x
⇒ 4x < 104
⇒ x < 26
So, the range of rental car rates that would be cheaper for Jamal than the taxi service is given by,
A ={x| 0 ≤ x < 26} [where x is in dollar]
