Answer: The number can be used to express the change in temperature= -14
Step-by-step explanation:
Given: The temperature in evening dropped by .
Thus, the change in temperature =
Since the temperature in evening is dropped or decreased , thus in integers the change in temperature =
Therefore, the number can be used to express the change in temperature= -14
Answer:
QUESTION 1

We simplify to get.
The correct answer is option A.
1.
A.) (4, −2)
2.
x = -7
y = 2
3.
x = 5
y = 14
QUESTION 2
The given system of equations is
and
We make y the subject in equation (2) to get,
We put equation (3) into equation (1) to obtain,
We group like terms to get,
This implies that,
we divide through by to get,
Hence the x-coordinate is
QUESTION 3
The given system is
and
We make the subject in equation (2)
We put equation (3) into equation (1) to obtain,
We expand the bracket to get,
Group like terms to get,
We simplify to get;
This implies that,
Therefore the y-coordinate is 14.
Step-by-step explanation:
Answer:
88 and 33
Step-by-step explanation:
- x=8y/3
- 8y/3-y=55⇒ 5y/3=55 ⇒ y=33
- x=8*33/3=88
Answer:
