Answer:
x = - 7
Step-by-step explanation:
Using the rule of exponents
× 
= 
Given
× 
= 6², then
= 6²
Since the bases on both sides are equal then equate the exponents
9 + x = 2 ( subtract 9 from both sides )
x = - 7
Answer:
20t + 9
Step-by-step explanation:
12+5t−4+15t+1
20t + 9
(Simplified version)
Let's present a solution for the generic case.
The equation will be of the form y=ax+b
If (7,3) is on it, then 3=7a+b
If (14,6) is on it, then 6=14a+b
Now we have a system we can solve.
3=7a+b => b = 3-7a
6=14a + 3-7a => 3 = 7a => a=3/7
b = 3-7*3/7 = 0
So y = (3/7)x is the equation.
