I think it’s 4y+31 but check if it’s correct
For this case we have the following expression:
Let's evaluate the expression for some values of x.
We have then:
For x = 1:
For x = 2:
For x = 3:
For x = 4:
For x = 5:
Answer:
The value of the expression in ordered pairs is:
- (1,8)
- (2.6)
- (3,4)
- (4.2)
- (5.0)
First find the area of the blue notebook by using the formula A=bh
A= 20×30 = 600 cm squared
Now find the area of the stickers using the same formula.
A=bh
A= 2 × 2 = 4 cm squared
Since there are 7 stickers then 4×7 = 28 cm squared is the area of all of them added together. Now simply subtract the area of the stickers from the area of the notebook to find how much of the notebook is still showing.
600 - 28 = 572 cm squared
Find slope as negative reciprocal of 2 => m=-1/2
y=mx + b
8=5(-1/2) +b
b=21/2
y= -1/2x +21/2
