Answer:

  • $2 per pound

Step-by-step explanation:

Let the cost of apples be x

<u>Then we have equation:</u>

  • (9 - 1.5)x = 15
  • 7.5x = 15
  • x = 15/7.5
  • x = 2

<u>Cost of apple:</u> $2 per pound

How many times does the graph of the function below interect or touch the x-axis? y=-2x^2+3x+5
Andrei [34K]

Answer:

Two times at (-1,0) and (2.5,0)

Step-by-step explanation:

When the graph intersects or touches x-axis, y is equal to 0

so y = -2x^2 + 3x + 5

=> 0 = -2x^2 + 3x + 5

The formula to solve a quadratic equation of the form ax^2 + bx + c = 0 is equal to x = [-b +/-√(b^2 - 4ac)]/2a

so a = -2

    b = 3

    c = 5

substitute in the formula

x = [-3 +/- √(3^2 - 4x-2x5)]/2(-2)

x = [-3 +/- √(9 + 40)]/(-4)

x = [-3 +/- 7]/(-4)

x1 = (-3 + 7)/(-4) = 4/-4 = -1

x2 = (-3 - 7)/(-4) = -10/-4 = 5/2 = 2.5

so the graph has two x-intercepts (-1,0) and (2.5,0), therefore it intersects x-axis two times

She travels one block every minute

<em><u>To find: time taken by Meredith to reach friend house</u></em>

Number of blocks between Meredith house and her friedn house = 24

She travels one block every minute

Thus she takes 1 minute for 1 block

One block = 1 minute

So, for 24 blocks, we have to multiply by 24

24\ block = 1 \times 24\ minute\\\\24\ block = 24\ minute

Thus Meredinth takes 24 minutes to reach her friend house
