Coordinates of the y-intercept is (0, -5)

Step-by-step explanation:

Step 1: Given the slope of the line, m = 3. Point on the line is (1, -2). Here x = 1 and y = -2. Substitute in the equation y = mx + b to find b.

⇒ -2 = 3 × 1 + b

⇒ b = -5

⇒ Coordinates = (0, -5)

Find the inverse function

Alex

The inverse of this function is f(x) = $\frac{3x + 15}{4}$

To find the inverse of any function, start by switching the x and f(x) term. Then solve for the new f(x). The result will be the inverse function. The step-by-step process is below for you.

f(x) = $\frac{-15 + 4x}{3}$ ----> Switch the x and f(x)

x = $\frac{-15 + 4f(x)}{3}$ ----> Muliply both sides by 3

3x = -15 + 4f(x) ----> Add 15 to both sides

3x + 15 = 4f(x) ----> Divide both sides by 4.

f(x) = $\frac{3x + 15}{4}$

c. an algorithm

Step-by-step explanation:

Most math problems are best solved using an algorithm. Certainly, converting numbers from one form to another is easily done that way.

_____

The integer part is the whole-number quotient of the division. The fractional part is the remainder divided by the denominator:

39/8 = 32/8 + 7/8 = 4 7/8

In February, Alec had 1,562 visitors to his website. In March, he had 1,310 visitors to his website. What is the percentage decr

tigry1 [53]

Answer:

16.1% is the percentage decrease.

Step-by-step explanation:

We are given the following in the question:

Visitors in February = 1,562

Visitors in march = 1,310

We have to find the percentage decrease of the number of visitors to Alec's website from February to March.

Percentage decrease =

$=\dfrac{\text{Change}}{\text{Original}}\times 100\%\\\\=\dfrac{1562-1310}{1562}\times 100\%\\\\=\dfrac{252}{1562}\times 100\% = 16.1\%$

Thus, 16.1% is the percentage decrease in the number of visitors to Alec's website from February to March.
