Y² + 16 = 212
<span>y</span>² <span>= 196 </span>
<span>y = -14 and 14</span>
The answer is <span>x - 1 = 3x + 9
All steps are:
</span>Step 1: 4ˣ⁻¹ = 64ˣ⁺³<span>
Step 2: 4</span>ˣ⁻¹ = (4³)ˣ⁺³ <span>
Step 3: 4</span>ˣ⁻¹ = 4³ˣ⁺⁹
Step 4: x - 1 = 3x + 9
Step 5: x - 3x = 1 + 9
Step 6: -2x = 10
Step 7: x = 10/-2
Step 8: x = -5
M = -8
-15 minus -7 equals -8
Answer:

Step-by-step explanation:
Let
n -----> number of tickets
C ----> represent the cost of buy n tickets online
we have the ordered pairs
(1,16.50) and (2,30.50)
<em>Find out the slope of the linear equation</em>
The formula to calculate the slope between two points is equal to
substitute the values
<em>Find the equation of the line in slope intercept form</em>

we have
