Its 75 dollars so 250-75 =175 plz mark brainlest
Answer:
R'(-3,2)
S'(-5,-2)
T'(-6,0)
Step-by-step explanation:
Since it is reflected over the y axis, the x coordinates would be opposite.
For example,
(9,6) = (-9,6)
Answer:
B
Step-by-step explanation:
I think the answer is bbecause for perimeter you just add all the sides up. so you would add 8+8 or 8x2 which would be 16 and 3x2 or 3+3 which is 6. Then you add the two roducts you got together to find the final sum added together which would be 22.
Given:
The expression is:
To find:
The simplified value of the given expression.
Solution:
We have,
On dividing, we get
Here, quotient is and the remainder is .
Therefore, .
Answer:
Let the speed of the train be x km/h.
Case 1:
Distance = 288 km
Speed = x km/h
Time = Distance/Speed
= 288/x h
Case 2:
Distance = 288 km
Speed = (x+4) km/h
Time = 288/x + 4 h
Since 288/x > 288/x + 4
288/x - 288/x+4 = 1
288[1/x - 1/x+4 ] = 1
[ x + 4 - x / x(x + 4) ] = 1/288
[4 / x^2 + 4x ] = 1/288
x^2 + 4x = 1152
x^2 + 4x - 1152 = 0
x^2 + 36x - 32x - 1152 = 0
x(x + 36) - 32(x + 36) = 0
(x + 36)(x - 32) = 0
x + 36 = 0 , x - 32 = 0
x = -36 , x = 32
x = -36 , rejected since speed cannot be negative.
Therefore , speed of the train = 32 km/h
