Answers

so first of all we need to get rid of the time that isn't spent in class, because the question is asking about the time spent in class. so we would add 30+42 giving us 72 minutes, or 1 hour and 12 minutes. Now we can subtract 1 hour and 12 minutes from 7 hours to find the total time spent in class. Which would give us 5 hours and 48 minutes. (reminder; 60 minutes in 1 hour)

now that we have the total time spent in class, all that is left is division. The equation would be easier to solve when the hours are converted into minutes. 5 hours and 48 minutes equal, 348 minutes. Now we would divide 348 by 6 as there are 6 classes that take 348 minutes in all, and we wanna find how long 1 class takes. 348 divided by 6 would then give us 58. so each class takes 58 minutes.

Which equation describes a relationship such that x = 0 must be excluded from the domain?

Answers

Answer:

Example: f(x) = (1 + x + x^2) / x, x=0 is excluded from the domain, since division by zero is undefined.

Step-by-step explanation:

This is because it only has an x-intercept and does not intersect they-axis. Vertical lines cannot be written in standard form because the slope is undefined. The equation of the line is given by the x-intercept of the line. In this case x=0 goes though the origin (x=0), which means this is the equation of the y-axis

F(x)= 2x^3 + 5x^2 -x -6 is divided by x+1

The ratio of the side length of square A to the length of Square B is 4:9 The side length of square A is 12 yards. What is the perimeter of Square B

Answers

Step-by-step explanation:

side A / side B = 4/9

side A = 12 yards

=>

12 / side B = 4/9

12 = side B × 4/9

9×12 = side B × 4

side B = 9×12/4 = 9×3 = 27 yards

perimeter of B is 4×side B = 4×27 = 108 yards

Find the slope and the y intercept then use them to graph the line I also need to know where to plot the points I’ll give BRAINLIEST

Answers

Answer:

slope = 3

y-intercept = -4

Step-by-step explanation:

In order to find the slope and the y-intercept, transform the given equation into its slope-intercept form, y = mx + b:

Add 9x to both sides:

-9x + 9x + 3y = 9x - 12

3y = 9x - 12

Divide both sides by 3:

[tex]\frac{3y}{3} = \frac{9x - 12}{3}[/tex]

y = 3x - 4    This is the slope-intercept form where the slope, m = 3, and the y-intercept, b = -4.

To graph the line, start at the y-intercept (0, -4). Then, use your slope, m = 3 (rise 3 units, run 1 unit).  Attached is a screenshot of the graphed line, using the rise/run technique. I also plotted extra points.
