Adding and subtracting fractions 3/5 + 4/7

Mathematics
1 answer:
svlad2 [7]3 years ago
8 0

Answer:

1 and 6/35

Step-by-step explanation:

You would want to multiply the denominators with the same number.

5×7

Multiply the numerators as well.

3×7 and 4×5

The fractions you would have now is 21/35 and 20/35, you can now add them up without having difficulties if the denominator is the same number.

You can also change it into decimals but I suggest this strategy.

The standard form of the equation for a quadratic function is, with he vertex of the graph of the function at the point (p,q). t
ludmilkaskok [199]

Answer:

p = ½ (x₁ + x₂)

q = a (x₁x₂ − ¼ (x₁ + x₂)²)

Step-by-step explanation:

y = a (x − x₁) (x − x₂)

Expand:

y = a (x² − x₁x − x₂x + x₁x₂)

y = a (x² − (x₁ + x₂)x + x₁x₂)

Distribute a to the first two terms:

y = a (x² − (x₁ + x₂)x) + ax₁x₂

Complete the square:

y = a (x² − (x₁ + x₂)x + ¼(x₁ + x₂)²) + ax₁x₂ − ¼ a(x₁ + x₂)²

y = a (x − ½ (x₁ + x₂))² + a (x₁x₂ − ¼ (x₁ + x₂)²)

Therefore:

p = ½ (x₁ + x₂)

q = a (x₁x₂ − ¼ (x₁ + x₂)²)
