Answer:
a = -11, 17.
Step-by-step explanation:
-7 = |a-3| / -2
Multiply both sides by -2:
|a - 3| = 14
So a - 3 = 14
Giving a = 17
or
a - 3 =- -14
giving a = -11.
Checking these values:
-7 = |17-3| / -2 = 14/-2 = -7
- so a = 17 is a solution.
-7 = |-11-3| / -2 = 14/-2 = -7
so a = -11 is also a solution.
You must divide the larger by the smaller... That will give you the scale factor.
For example: Rectangles 10 x 20 and 5 x 10
the scale factor us 10/5 = 20/10 = 2
Hope this helps.
The common difference based on the sequence given is 15.
<h3>How to illustrate the sequence?</h3>
It should be noted that the sequence given Isa arithmetic sequence.
The common difference will be the second term minus the first term. This will be:
= 101 - 86
= 15
In conclusion, the difference is 15.

Answer:
y=1
Step-by-step explanation:
Ⓗⓘ ⓣⓗⓔⓡⓔ
Well, the ratio of x:y are 3:1
Because the x is literally 3, the ratio is...3:1.
Hence, y=1

Answer:
2
Step-by-step explanation:
If we look at the graph this is an increasing graph where y increases with respect to x so in other words we can say that y is directly proportional to x.
and when we remove the proportionality sign we replace it with an equal to sign and a constant. So it becomes ,
now to find the Constant of proportionality which is k we can use any ordered pair(coordinate/point) from the graph,
Lets take ( 2 , 4) where 2 represents the value of x on the x-axis and 4 represents the value of y on the y-axis so now,
so the constant of proportionality is 2
