The slope would be c, vertical line is 0

The answer would be d. This is because parallel lines have the same slope. Lets say the first line is f(x). The slope of this would be undefined because all the x-coordinates are the same, so if you tried to find the slope, you would use the slope formula, y^2-y^1/x^2-x^1 and if we used the points (1, 1) and (1,2) we would end up with 2-1/1-1 = 1/0. Because there is a zero in the denominator, it makes f(x) undefined. And as I said before, parallel lines have the same slope, f(x)' would also be undefined.

The system of equations are y = 35 - 2.2x and y = 1.7x

Solution:

Given that, office building has two elevators.

One elevator starts out on the 4th floor, 35 feet above the ground, as it’s descending at a rate of 2.2 feet per second

Let "x" be the number of seconds for which the elevator is descending

Therefore, for "x" seconds the descended feet is 2.2x feet

The elevator is at 4 th floor, 35 feet above ground

Therefore, from 35 feet, the elevator has descended 2.2x feet for "x" seconds

Let "y" be the final position of elevator after "x" seconds

Therefore,

y = 35 - 2.2x

The other elevator starts out at ground level and is rising at a rate of 1.7 feet per second

Here, the elevator is rising at a rate of 1.7 feet per second

Therefore, for "x" seconds, the elevator has raised 1.7x feet

Here the elevator is at ground level, therefore

y = 1.7x

Thus the system of equations are y = 35 - 2.2x and y = 1.7x

In ΔABC, what is the measure of angle B?

DiKsa [7]

This theorem says that the exterior angle is equal to the sum of its remote interior angles. In other words, 140 = 2x + x + 2. 140 = 3x + 2 and 138 = 3x. Therefore, x = 46. Multiply it by 2 to get angle B is 92 degrees.

The volume of a sphere is found using the formula V= 4/3 3.14r^3. If the radius of a sphere is 3/4 feet, what is the volume of t

Rufina [12.5K]

The volume of the sphere is expressed in the formula V= 4/3 3.14r^3 and we are given the radius of the sphere. to find the volume, we can directly substitute r as the unit of the volume to be determined is consistent with the given. Hence, via subsitution, the answer is 1.7671 cubic feet

A zoo is keeping track of the weight of a baby elephant.the table shows the weight for the first, second, third, and fourth week

True [87]

Hello!

I would say the second option, because it looks like the most reasonable one. The third and fourth options decrease, but we can see by the chart that in fact, the weight increases. Also, it wouldn't be the first option, because its showing that the wight is always constant and rate doesn't change. However, we can see that this is wrong and the rate actually does change. Therefore, the second option looks like the most reasonable for this chart.

Hope this helps!
