Answer:
The percentage of decrease is approximately 0.14%.
Step-by-step explanation:
35 - 5 = 30
What percentage is 5 of 35 (x/100 = is/of)
x/100 = 5/35 (cross multiply)
(5*100)/35 = 14.29%
Given that f(x) = 2x + 11: if f(x) = y = 21, then 21 = 2x + 11, and so 10=2x and x=5.
Thus, f(5) = 2(5) + 11 = 21; (5,21) is a point on the graph of f(x).
If that is so (which it is), then (21,5) is a point on the graph of the inverse function, and 5 is the appropriate output value.
Answer:
Let's create this right triangle. We will call it triangle ABC with angle B as the right angle, angle A being the larger of the angles A and C. If the ratio is 5:4, then it is A:C. 5+4 = 9. The measure of the right angle, angle ABC = 90, and 90 divided by 9 is 10. So angle A is 5 * 10 which is 50 degrees, and angle C is 4 * 10 which is 40 degrees. The smallest angle, angle C, is 40 degrees.
Step-by-step explanation:
Answer: 48 model cars.
Step-by-step explanation:
1. You know that the ratio of the number of model cars that Jim owns to the number of model cars Terrence owns is 4:3.
2. Let's call the number of model cars that Jim owns is 
, therefore, you can solve the exercise as following:
3. Therefore, Jims owns 48 model cars.
Answer:
4x^2 + 4x - 8 = 4*(x^2 + x - 2)
(x - 1) * (x - a) = x^2 + x - 2 --> a = -2
