Answer:
b. y=sec(x/3) and y=-1
Step-by-step explanation:
sec(x/3) + 4 > 2 − sec(x/3)
2 sec(x/3) > -2
sec(x/3) > -1
Graph y = sec(x/3) and y = -1.
The original price is 67 and 4 percent dissocount
Solve for y (change the equation to slope-intercept form.
2y = 2x + 8. Divide each term by 2
y = x + 4.
So slope is 1
Answer:
x = ± 
Step-by-step explanation:
Given
+
= 1
Multiply through by a²b² to clear the fractions
b²x² + a²y² = a²b² ( subtract a²y² from both sides )
b²x² = a²b² - a²y² ( divide both sides by b² )
x² =
( take the square root of both sides )
x = ±
