Answer:
8
Step-by-step explanation:
Length = 2x-4
Width = x+1
Let x=3 and find the length and width
Length = 2*3-4 = 6-4 =2
Width = x+1= 3+1 =4
The area is given by
A = l*w = 2*4 = 8
Yes it is. Hope this helps
Answer: This is <u>not</u> a function
Why not?
The input x = 2 leads to more than one output. In this case, it leads to y = 20 and y = 40 simultaneously. This is the reason why we don't have a function. A function is only possible if each input x leads to exactly one y output.
Put another way: we cannot have x repeating any values if we want a function.
Side note: We could have y repeat however. So it's possible to have a function with the two points (1,5) and (3,5).
Answer:
3 times 7 is 21
Step-by-step explanation:
Answer:
Let's simplify step-by-step.
8.3+3.4y−0.5(12y−3)
Distribute:
=8.3+3.4y+(−0.5)(12y)+(−0.5)(−3)
=8.3+3.4y+−6y+1.5
Combine Like Terms:
=8.3+3.4y+−6y+1.5
=(3.4y+−6y)+(8.3+1.5)
=−2.6y+9.8
Answer:
=−2.6y+9.8
