Is just a set of two or more linear equations. In two variables (x and y) , the graph of a system of two equations is a pair of lines in the plane.
The correct answers are the 3rd and 4th ones.
Answer:
9x + 8.
Step-by-step explanation:
2(x - 3) + 7(x + 2)
= 2x - 6 + 7x + 14
= 2x + 7x - 6 + 14
= 9x + 8.
Hope this helps!
Answer:
Exponential
Step-by-step explanation:
This equation represents an exponential function because it will have exponential growth. The equation has a variable as an exponent which causes exponential growth. If it were linear there would be constant growth and a common difference.
<h3>
Answer: 4^15</h3>
Explanation:
The rule used is
a^b*a^c = a^(b+c)
Basically you add the exponents. This only applies if the bases are both the same. In this case, they're both 4 so the rule works out.
Using the rule, we get
a^b*a^c = a^(b+c)
4^5*4^10 = 4^(5+10)
4^5*4^10 = 4^15
