Answer: 8.3 ounces
Step-by-step explanation:
simple, there's a flat fee for 1 ounce, then 23 cents for each ounce following.
so $2 - $0.32 = $1.68
1.67 / 0.23 = 7.3 ounces
7.3 ounces + 1 ounces (from the flat fee we subtracted)
which equals 8.3
It is not true because if you add in 0 the equation would be 8-4(0)=4(0)
4x0 = 0
so it would be 8-0=0 which doesn't add up.
Answer:
a)
T` {-4,-2}
R` {2,8}
S` {-9,4}
Step-by-step explanation:
x, y → y,x
Answer:
The other endpoint is (-33, 17)
Step-by-step explanation:
The rule of the mid-point of a segment whose endpoints are
(
,
) and (
,
) is
In our question
∵ The coordinates of the endpoints of a segment are (-15, 13) and (x, y)
∴
= -15 and
= x
∴
= 13 and
= y
∵ The coordinates of the mid-point of this segment are (-24, 15)
∴
= -24 and
= 15
→ Use the rule of the mid-point to find x and y
∵ 
→ Multiply both sides by 2
∴ -48 = -15 + x
→ Add 15 to both sides
∴ -33 = x
∵ 
→ Multiply both sides by 2
∴ 30 = 13 + y
→ Subtract 13 from both sides
∴ 17 = y
∴ The other endpoint is (-33, 17)
