A) x * y = 12
B) x + y = -7
A) x = 12 / y
Substitute this into B
B) 12/y + y = -7
multiplying both sides by "y"
12 + y^2 = -7y
y^2 + 7y + 12 = 0
y = -4
and from equation B we calculate x as -3
Answer :
The value of x is 10.
Explanation :
Given that,
TM = (2x+8) m
ML = (3x-2) m
If a man (M) is standing halfway between a tree (T) and a lamppost (L).
The half distance is TM and half distance is TL.
So, Both half distance will be equal.
We need to calculate the value of x
Using given data
Put the value into the formula
Hence, The value of x is 10.
Answer: D
Step-by-step explanation:
The increase in temperature is positive, and the absolute value is always positive. So |-8 - 23| is your answer.

(0,0)
Explanation:
The rule you use is when it comes to 180 degree rotations (either clockwise or anticlockwise/counterclockwise). So we flip the signs of the x and y coordinates. Any point on an axis will stay on the same axis. The origin is the intersection of the two axes, so this point does not move at all. We call this point fixed or stationary. The fixed point is one where every point rotates around it.
Answer:
Jonathan is 36 years old.
Step-by-step explanation:
Jonathan=2 Lawrence
J= 2L
54 divided by 3 equals 18.
18 times 2 equals 36.
