Answer:

1).  Correct answer is D

2). Correct answer is A

Step-by-step explanation:

1).

For the points given, (-1, -1) and (2, -2), we have to find the slope.

Slope formula is (y2 - y1) / (x2 - x1), or rise over run.

Simply fill in the formula and you will get:

y2 = -2

x2 = 2

y1 = -1

x1 = -1

OR

(-2 - (-1)) / (2 - (-1)) which is D

2).

For the two points given, (2, 0) and (0, -3), find the slope.

Using the same equation above, (y2 - y1) / (x2 - x1), or rise over run, fill it in and solve and you will get your answer.

y2 = 0

x2 = 2

y1 = -3

x1 = 0

(0 - (-3)) / (2 - 0) = 3/2 which is A

Step-by-step explanation:

Graph A:

D ((y2-y1)/(x2-x1) or (y1-y2)(x1-x2))

Graph B:

A (same as above or simply take the rise divided by the run)

If f(x) and its inverse function, f(x), are both plotted on the same coordinate plane, where is their point of intersection?
Tcecarenko [31]

Answer:

(2,2)

Step-by-step explanation:

The graph of a function and that of its inverse should be always symmetric around the line y = x (goes at 45 degrees and crosses the origin of coordinates).

Therefore any intersection of the graphs must lie on the line y = x, which forces the x value of the intersection point to be the same as the y-value.

The only option shown where x and y have the same numerical value is the third listed option : (2,2)

Make b the subject.
sp2606 [1]
First, square both sides. This will cancel out the radical.
a^2 = b \add 6
(a^2 = b + 6)
Then subtract 6 from both sides
b = a^2 - 6

In the equation shown below what is the "a"value? <br><br> y= 2x2square +4x -9
Marat540 [252]

Answer:

The "a" value is 2x^2

Step-by-step explanation:

This is because it is the first part of the equation. The parts of the equation are given the values a, b, and c based on their position in the equation.

HELP NOW PLEASE is say for each pair of angle in parts A thought D estimate the measure of each angle.
Mice21 [21]

Answer: A: V is an acute angle, so it is less than 90 degrees. I would say it's around 45 degrees.

B: K is also an acute angle, but it is fairly close to being 90 degrees, so I'd say around 80 degrees.

C:  Q is an obtuse angle, so it is over 90 degrees but less than 180 degrees. I would say it's around 110 degrees.

D: Y is an obtuse angle. It is very close to 180 degrees. I would say it's around 160 degrees.
