We have

$\displaystyle \int_{-2}^2 f(x) \, dx - \int_{-2}^{-1} f(x) \, dx = \int_{-1}^2 f(x) \, dx$

so that

$\displaystyle \int_{-2}^2 f(x) \, dx + \int_2^5 f(x) \, dx - \int_{-2}^{-1} f(x) \, dx \\\\ ~~~~~~~~~~~~ = \int_{-1}^2 f(x) \, dx + \int_2^5 f(x) \, dx \\\\ ~~~~~~~~~~~~ = \boxed{\int_{-1}^5 f(x) \, dx}$

Rufina [12.5K]

Answer:

The equation is x = y * 4/5 and US$ 12 would equal 15 Swiss Francs

Step-by-step explanation:

1. Let's review all the information provided for solving this question:

1 US$ equivalent to 1 1/4 Swiss Franc

2. Let's write and solve a multiplication equation to find the amount of US$ that would equal 15 Swiss Francs

x = Amount of US$ equivalent

y = Amount of Swiss Francs

x = y /1.25

x = y / 5/4 (1.25 = 5/4)

x = y * 4/5

Now, let's replace with the real values:

x = 15 * 4/5

x = 60/5

x = 12

US$ 12 would equal 15 Swiss Francs

Question 2 Multiple Choice Worth 1 points)

Tomtit [17]

Answer: "Subtract 6 from both sides, and then divide by 2. The solution is x = 8"

Step-by-step explanation: Lets solve for 2x + 6 = 22

Step 1 Subtract 6 from both sides: 2x + 6 - 6 = 22 - 6 2x = 16

Step 2 Divide by 2 in both sides: 2x/2 = 16/2

Step 3 The answer: x = 8
