Solve the quadratic formula

X^2-5x-14=0

Answers

Answer 1

Answer:

Step-by-step explanation:

Sum = -5

Product = -14

Factors = 2 , (-7)      because 2*(-7) = -14 and 2 + (-7) = -5

x²  - 5x - 14 = 0

x² + 2x - 7x - 14 = 0

x(x + 2) -7(x + 2) = 0

(x + 2)(x - 7) =0

x + 2 = 0           ;  x -7 =0

     x = -2  ;            x  = 7

What is the probability of getting 2 blues?


PLZ answer fast its an emergancy

Answers

Answer:

5/11*5/11=25/121

Step-by-step explanation:

There are 6+5 marbles.

Of those, 5 are red.

The chances of drawing a red marble are 5/11

Since you replace the marble you drew, the chances each draw remain 5/11

You cannot draw two red marbles without drawing a red marble on your first draw, so the odds of you making a second draw are 5/11. The odds of that also being red are 5/11… but we only care about that 5/11ths the time

Graph the equation.
y= 5(x + 1)^2– 3
HELP!!!

Answers

Step-by-step explanation:

the answer is in the attachment

The graph of the function y= 5(x + 1)²– 3 is attached accordingly. See the description of the graph below.

The graph of y= 5(x + 1)²– 3

The equation y = 5(x + 1)² - 3 represents a quadratic function.

The graph is a parabola with its vertex at (-1, -3). It opens upward since the coefficient of the squared term (x²) is positive.

The graph is vertically stretched by a factor of 5 compared to the standard quadratic function.

The x-coordinate of the vertex is -1, indicating a horizontal shift of 1 unit to the left from the standard quadratic.

SPORTS A coach uses a metric to determine the athletes that make the Varsity, Junior Varsity A, and Junior Varsity B teams. The total number of points possible on a skills test is 350. Athletes will make "Varsity" with at least 90% of the points. Athletes will make "Junior Varsity A" for 70-89% of the points. Athletes will make "Junior Varsity B" for 50-69% of the points. The table shows the number of points for each athlete that tried out.

Answers

Answer:

there is no picture. :)

Step-by-step explanation:

Answer:

Varsity = 12

Jr Varsity A = 10

Jr Varsity B = 11

Step-by-step explanation:

Varsity = at least 90%  = 350 times 90% = 315

Anything 315-350

Jr Varsity A = 70-89%

350 times 70% = 245

350 times 89% = 311.5

Jr Varsity b = 50-69%

350 times 50% = 175

350 times 69% = 241.5
