Is the discriminant of g positive, zero, or negative?

Answer:

y=x+8

Step-by-step explanation:

slope = y2-y1/x2-x1

slope = 7-5/-1+3

slope = 2/2

slope = 1

y=x+b

7=1(-1)+b

7=-1+b

b=8

y=x+8

Answer:

9

Step-by-step explanation:

You choose the middle one because 3<(4)<10 makes sense where as the other ones don't when you plug in 4. Then you solve the equation which is x^2-7 and then you get 16-7 which is 9.

Answer:

A

Step-by-step explanation:

Answer:

85%

Step-by-step explanation:

Divide the number of problems gotten right by the total number of problems.

Sarah got an 85%.

Use this method.

part/whole = %/100

So.

17/20 = x/100

Cross multiply.

17•100=1700

20•x=20x

Divide by 20

1700÷20=85

Therefore the answer is 85%

Answer:

x is 60 because the total of angles in a triangle is 180 degrees

Answer: 5

Step-by-step explanation:

Since we are given two angles and one side, we can use the side angle side comparison logic to figure out that all sides are 7 and all angles are 60. Since we are given that a side with length 7 is also 2x-3, we can infer that 2x-3=7. 2x=10, x=5. easy

Answer:

The area of the red carpet is 1057 ft²

Step-by-step explanation:

The area of the red carpet is 112.35 ft².

Given that, the width of the stage =63 ft and the length of the stage =10 2/3 ft.

The area of a rectangle is obtained by multiplying its length and width. Thus, the formula for the area, 'A' of a rectangle whose length and width are 'l' and 'w' respectively is the product "l × w".

Now, the width of the red carpet is 1/6 of the width of the floor = (1/6) × 63

=10.5 ft

Here, 10 2/3 can be written as 10.66 ≈ 10.7 ft

The area of the red carpet = length × width = 10.7 × 10.5

=112.35 ft²

Therefore, the area of the red carpet is 112.35 ft².

x = 96°

Answer → x = 96° (degree)

Answer:

96 Degrees

Step-by-step explanation:

If we look at the problem, we know that due to the fact that they are adjacent that they MUST be equal.

Here is the proof:

We'll assign each angle a letter as following

A B C D with A being the top left and D being the bottom right!

Now that we know that, first off, A has to be equal to 180-96 due to them being Supplementary Angles.

Therefore, A is 84 degrees.

Now to find x, we can use Supplementary Angles again.

x has to be 180-84 which is 96 degrees proving the theorum.

The proof of the value of the inverse equation f^-1(50) = 3 is below

From the question, we have the following parameters that can be used in our computation:

f(x) = 2x^3 - 4

To show that f^-1(50) = 3, we simply show that

f(3) = 50

substitute the known values in the above equation, so, we have the following representation

f(3) = 2 * 3^3 - 4

Evaluate

f(3) = 50

Hence, the proof of the value of the inverse equation is done

1. The  Triangle proportionality theorem can be used to  find a missing length in a right triangle.

The triangle proportionality theorem states that if a line parallel to one side of a triangle intersects the other two sides at different points, then it divides the remaining two sides proportionally.

2. By triangle proportionality theorem:

Answer:

399 minutes a month

Step-by-step explanation:

As I understand the question the answer would, in other words, be how many minutes you can long-distance call with the economy plan for under $30.

The unit ratio is 5 cents per minute, which equates to 20 minutes worth of call time for one dollar (100/5).

The economy plan is $20 cheaper than the deluxe plan. $20 spent on long-distance calling gets you 400 mintues, but the question asks for an integer that would still leave remaining money.

Therefore the answer is 399 minutes of long-distance calling, which would leave five unspent cents.
