Answer:
Step-by-step explanation:
The midpoint divides the segment into two equal lengths:
AB = BC
5x -2 = 9x -10
8 = 4x
2 = x
AB = 5(2) -2 = 8
AC = 2AB = 2(8) = 16
3x +2= 5x
-3x
2= 2x
/2
1= x
So first I got all the x’s on one side and the whole numbers on the other side. So we had 2 on one side and 2x on the other. From there we divided by the number of x’s which was 2 so we can get one x only. So 2/2= 1 so x =1
Answer:
The answer is below
Step-by-step explanation:
She decides the width of the board should be atleast 35% of the length.
Solution:
Let x represent the length of the bulletin board and y be the width of the bulletin board. Since there is 100 inches available, hence:
Perimeter = 2(length + width)
100 = 2(x + y)
x + y = 50
Also, since the width is 35% of the area, hence:
y = 35% of x
y = 0.35x
Since:
x + y = 50
x + 0.35x = 50
1.35x = 50
x = 37.04
x ≅ 38 inches to the next whole number
x + y = 50
y = 50 - 38
y = 12 inches
The bulletin board is 38 inches by 12 inches
Hello!
To first understand this question, we have to know what a domain is, and what it means to be linear.
The domain is all the possible x values.
Currently, in this graph, it starts at 0, and goes to some point further on.
To be linear means that you have linear growth, which this does not. This has a bend in it, which is not linear.
So, you must restrict the domain such that you only have a linear section.
If you look at the graph as a whole, it makes a bend. But, if you only look at x value 6 and up, it seems quite straight.
So, this makes sense!
Hope this helps, feel free to ask questions in comments.
