Answer:
Exponential
Step-by-step explanation:
So let’s start off by looking at how much x is growing by each time
X is growing by 8 each time
Next look at how much y is growing by
-6 to -24 is a difference of 18
-24 to -96 is a difference of 72
And lastly -96 to -384 is a difference of 288
So we can now say that it is not linear because a linear equation grows by a constant number (like adding)
To determine if it is exponential see if it is growing by a constant multiplier
24 divided by 6 is 4
96 divided by 24 is 4
384 divided by 96 is 4
It is exponentially growing by 4
Answer: x = 4
y = 1
Step-by-step explanation:
The given system of simultaneous equations is expressed as
- 5x + 13y = -7 - - - - - - - - - - - - 1
5x + 4y = 24 - - - - - - - - - - - - - 2
The first step is to decide on which variable to eliminate. Let us eliminate x. We would eliminate x by adding equation 1 to equation 2. It becomes
13y + 4y = - 7 + 24
17y = 17
y = 17/17
y = 1
Substituting y = 1 into equation 2, it becomes
5x + 4 × 1 = 24
5x + 4 = 24
5x = 24 - 4
5x = 20
x = 20/5
x = 4
