f(x) = -5x - 15
Let y = f(x)
y = -5x - 15
Switch the x and y places, and solve for y:
x = -5y - 15
-5y = x + 15
y = (x + 15)/-5
y = -(x/5) - 3
So the inverse of : f(x) = -5x - 15 is
-x/5 - 3
Answer:
Step-by-step explanation:
midline: y = -2 (take the average of the min and max)
amplitude = 1.5 (distance from min or max to midline. Always a positive number)
period = 4pi
Answer:
no, 72 km/hr is equal to 20m per sec
Step-by-step explanation:
20 m = .02 km
.02 km per hour is equal to .02(3600) per hour, which is 72 km per hour
(you have to multiply my 3600 to get seconds into hours)
If we got 560 pounds for 800 dollars and x pounds for 1 dollar, this means that x = 560*1/800 <=> x = 56/80. Performing the calulation we get that x = 0.7
Answer:
Step-by-step explanation:
- <em>Binomial = 2 terms in the expression</em>
- <em>Third degree = highest added degree of variables in one term</em>
(A) It has 3 terms and highest degree of 4. It is trinomial of degree 4.
(B) It has 2 terms and highest degree of 3. It is binomial of degree 3.
(C) It has 2 terms and highest degree of 7. It is binomial of degree 7.
(D) It has 2 terms and highest degree of 3. It is binomial of degree 3.
