k0ka [10]

Answer:

Check the explanation

Step-by-step explanation:

The average amount of the exercise hours at the same time as I am at my home town is 50 hours a month

Which graph best represents -5y = -6x + 15
frutty [35]

Answer: Option c.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope and "b" is the y-intercept.

Given the equation:

-5y = -6x + 15

Solve for "y" in order to write in Slope-Intercept form:

y = \frac{-6}{-5}x + \frac{15}{-5}\\\\y = \frac{6}{5}x -3

Now you can identify that that the slope and the y-intercept are:

m=\frac{6}{5}\\\\b=-3

A posive slope means that the the line moves upward from left to right.

With this information, you can conclude that the the graph that  best represents the given equation is the graph shown in the Option c.

Which function is the inverse of f(x)= 3x+5 over 7
Pani-rosa [81]

f(x) = (3x+5)/7

Step 1:

we write f(x) as y

y=(3x+5)/7

Step 2:

switch y by x and x by y

x=(3y+5)/7

Step 3:

solve for y,

x=(3y+5)/7

multiply both sides by 7

7x=3y+5

subtract 5 from left side

3y=7x-5

divide both sides by 3

y= (7x-5)/3

f⁻¹ (x) =(7x-5)/3

marta [7]

Answer:

The answer is x=10

Step-by-step explanation:

5/6x - 10 = 1/3x -5 multiple both sides by 6

5x - 60 = 2x -30 move the terms

5x - 2x = -30 +60

3x = 30 divide by 3

x = 10
