Answer:

To find the values of x that make fg(x) > 0, we first need to find fg(x). We can do this by composing the functions, which means replacing x in g(x) with the expression for f(x):

fg(x) = f(g(x)) = f(2x + 1) = (2x + 1)^2 - 4

Now we can solve the inequality fg(x) > 0:

(2x + 1)^2 - 4 > 0

(2x + 1)^2 > 4

2x + 1 > 2 or 2x + 1 < -2

x > -1.5 or x < -2.5

So the values of x that make fg(x) > 0 are x > -1.5 or x < -2.5.

Step-by-step explanation:

y=3x+13; y=7x+17

Step: Solve y = 3x + 13 for y:

y=3x+13

Step: Substitute 3x + 13 for y in y = 7x + 17 :

y=7x+17

3x+13= 7x+17

3x+13+-7x=7x+17+-7x (Add -7x to both sides)

-4x+13=17

-4x+13+-13=17+-13 (Add -13 to both sides)

-4x=4

-4x/-4 = 4/-4 (Divide both sides by -4)

x=-1

Step: Substitute -1 for x in y=3x+13:

y=3x+13

y=(3)(-1)+13

y=10(simplify both sides of the equation)

Answer:

x= -1 and y= 10

The required number corn plants are on the farm are 21.

metre stick counting techniques. Count the seedlings for each metre of the row using a metre stick. To calculate plants per square metre, multiply that amount by 100, then divide it by the seed spacing in centimeters.

Let the number of rows be x.

the number of corn plants = x - 4

So,

x(x - 4) = 525

x^2 - 4x - 525 = 0

On solving the above quadratic equation, we get

x = 25, x = -21

Thus, number of corn plants in the row are 52 - 4 = 21

No, the absolute value of a number is always non-negative, meaning it is greater than or equal to zero, but it is not always equal to zero.

The absolute value of a number represents the distance of that number from 0 on the number line and a number can be positive or negative.

For example, the absolute value of 5 is 5, which is greater than zero. The absolute value of -5 is also 5, which is also greater than zero. The only time the absolute value of a number is equal to zero is when the number is zero, |0| = 0.

The price to tile the room is $3,240.

We must figure out how many tiles are required to cover the floor before multiplying that number by the cost per tile to get the cost of tiling the room.

To begin, we must change the room's measurements from meters to centimeters in order to make them consistent with the tile's size. Multiplying 9 by 100 and 7.5 by 100 will yield the results we need: 9m x 100cm/m = 900cm, and 7.5m x 100cm/m = 750cm

Since the room and tile dimensions are now both expressed in centimeters, we can calculate the number of tiles required to cover the space by dividing its size by the tile's area:

25 cm × 20 cm / 36000 cm / 500 cm = (900 cm x 750 cm) / 72

In order to cover the room, 72 tiles are required. We must multiply the quantity of tiles by the price per tile in order to determine the cost:

72 tiles x 45 cents each tile = 3,240

Therefore, the price to tile the room is $3,240.

This is a condition known as ankylosis, and it describes a situation in which two bones lose their contact with each other.

Ankylosis can result from a variety of causes, including trauma, infection, or degenerative joint diseases. In cases of trauma, the articulating surfaces of the bones can be damaged, leading to a complete absence of contact between the two bones. Similarly, if an infection is present, the cartilage and ligaments of the joint can be destroyed, leading to ankylosis.

Finally, in cases of degenerative joint diseases, such as arthritis, the joint's articulating surfaces can be damaged, leading to a complete loss of contact between the two bones.

The symptoms of ankylosis vary depending on the severity of the condition. In mild cases, the patient may experience stiffness, pain, and reduced range of motion in the joint. In more severe cases, the joint may become completely immobile, and the patient may have difficulty walking or performing other activities.

Answer:

D. (1,3) and (3,7)

Step-by-step explanation:

The graphs of y = 2x + 1 and y = -(x-1)^2 + 3 intersect at the points where they have the same y-coordinate. To find these points, we can set the two equations equal to each other and solve for x.

y = 2x + 1 = -(x-1)^2 + 3

2x + 1 = -x^2 + 2x + 2

x^2 - 4x + 1 = 0

(x-1)^2 = 0

x = 1

Now we can substitute this value of x into either of the given equations to find the corresponding y-coordinate.

y = 2x + 1 = 2(1) + 1 = 3

so the point of intersection is (1,3)

So the answer is D. (1,3) and (3,7)

By solving a linear equation we will see that there are 20 games left.

We know that there is a total of 100 games, and the ratio of wins to loses for the rockets is:

3:2

The ratio for the rangers is:

7:13

We know that if the rockets loses all the remaining games, and the rangers win all the remaining games then both teams will win the same number of games.

Let's define X as the number of games left, the number of games won by the rockets is:

(100 - X)*(3/5)

The number of games won by the rangers is:

(100 - X)*(7/20)

We know that if the rangers win the X games left, they will have the same number of wins than the rockets (if the rockets don't win any more game)

Then we can write the linear equation:

(100 - X)*(7/20) + X = (100 - X)*(3/5)

we can solve this for X.

X = (100 - X)*(3/5) - (100 - X)*(7/20)

X = (100 - X)*(3/5 - 7/20)

X = (100 - X)*(12/20 - 7/20)

X = (100 - X)*(5/20)

(20/5)*X = 100 - X

4*X = 100 - X

4*X + X = 100

5*X = 100

X = 100/5

X = 20

speed of ball = 11 ft./sec

location of the cup =  (0, 0)

starting location the ball = (-40. -50)

In order to find the possible x-coordinates of Q,

The coordinates of the rightmost edge of the golf course = (35, 0)

slope = m = ( y2 - y1)/ ( x2 - x1)

now , the equation for a circle is known as , (x - h)² + (y - k)² = r²

and the center of the course is given as ,  (h, k) = (0, 0)

Therefore the equation becomes (x - 0)² + (y - 0)² = x² + y² = 35²

equation of tangent , y = -3x/2

putting this value in the tangent = x² + ( -3x/2 )²  = 35²

13x² /4 = 35²

x = √ ( 35²  x 4 )/ 4 = 35²
