Answer:
Step-by-step explanation:
Let y be the total price and x be the months passed,
Since the enrollment fee is $50, the y-intercept would be 50 regardless of the months passed. Also, since the price increases by $60 every month, we know the gradient is 60.
Therefore, the equation is
Answer:
b. x=sin^-1(a/c)
c. x=tan^-1(c/a)
e. y=cos^-1(c/b)

Answer:
- The Expression will be defined if the denominator is not equal to 0 since any number divided by 0 is undefined.
- Therfore our main priority here is to check the denominator only because it's the only part that can make the expression undefined
- the expression will be defined for all real numbers (a) BUT 3+a must not equal to 0 therfore (a) can be all real numbers but must never be equal to -3

If D is the center of the circle, ∠ADB = 70°, as that is where the arc gets its measure.
If D is on the circle and not on the arc, ∠ADB = 35°, half the measure of the arc's central angle.
If D is on arc AB, then ∠ADB = 145°, half the measure of the corresponding central angle.
If D is inside or outside the circle (and not one of the above), we need to know more about the measures of arcs intercepted by lines AD and BD.
Answer:
y = -1/10
Step-by-step explanation:
-2/5 + y = -1/2 First, make a common denominator for the fractions
-4/10 + y = -5/10
+4/10 +4/10 Add 4/10 to both sides
y = -1/10
