Which slope is steeper 4/8 or 3/10 and why
pashok25 [27]

Answer:

4/8 is steeper than 3/10

Step-by-step explanation:

4 is half of 8 and in decimal form is 0.5. 3/10 in decimal form is 0.3. Therefore 0.5 is greater than 0.3, so 4/8 is considered to be steeper than 3/10.

1. Determine whether the lines given by the equations 2x + 3y = and y=3/2x+4
son4ous [18]

Answer:

1. Yes, the lines are perpendicular.

2. y=\frac{5}{4}x+6

Step-by-step explanation:

The first equation of Exercise 1 is incomplete. Let's assume that it is:

2x + 3y =n

Where "n" is a number.

First, it is important to remember that the equation of a line in Slope-Intercept form is:

y=mx+b

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

By definition, the slopes of perpendicular lines are negative reciprocals.

1 . If you solve for "y" from the first equation, you get:

2x + 3y =n\\\\3y=-2x+n\\\\y=-\frac{2}{3}x+\frac{n}{3}

You can identify that the slope is:

m=-\frac{2}{3}

The second equation of the line is:

y=\frac{3}{2}x+4

And its slope is:

m=\frac{3}{2}

Since the slopes are negative reciprocals, the lines are perpendicular.

2. Given the first equation of the line:

y= -\frac{4}{5}x+6

You can identify that:

m=-\frac{4}{5}\\\\b=6

Since the first line and the second one are perpendicular, you know that the slope of the other line is:

m=\frac{5}{4}

According to the information given in the exercise, both lines have the same y-intercept; therefore, the equation of the second line is:

y=\frac{5}{4}x+6

The volume of cube x divided by the volume of cube y is 27. What is the side length of cube x divided by side length of cube y
Svetach [21]
If the volume of cube x divided by the volume of cube y is 27, then <span>he side length of cube x divided by side length of cube y would be 3. This is computed by solving the cube root of 27, since the side of the cube was multiplied thrice to get the volume so when geeting the side of the cube it is best to have the number be in cube root form.</span>
