8 * 5/7 equalfind the product write the product in its simplest form 8 * 5/7 ​
Naily [24]

The product of 8 and 5/7 is 5.7

<u>Step-by-step explanation:</u>

The given product is 8 \times 5/7.

<u>In the product, two terms are given :</u>

  • The first term 8 is a whole number.
  • The second term 5/7 is a fraction.

1) So, to find the product of the first term and the second term, one method is to simplify the fraction into decimal number and then perform multiplication operation.

2) Either you can multiply the two terms in the first step and then the division operation is performed at the final step.

<u>First method :</u>

<u><em>Step 1 :</em></u> Convert the fraction into decimal

⇒ 5/7 = 0.71

<u><em>Step 2 :</em></u> Multiply the result with the other term.

⇒ 8 × 0.71

⇒ 5.68 (approximately 5.7)

<u>Second method :</u>

<u><em>Step 1 :</em></u> Multiply both the terms

⇒ 8 ×(5/7) = 40/7

<u><em>Step 2 :</em></u> divide 40 by 7

⇒ 40÷ 7 = 5.7

Therefore, the product of 8 and 5/7 is 5.7

What is the domain of f (x) = 4 + 2x on a graph when the range is (0,6)
galina1969 [7]

Answer:

(-2, 1).

Step-by-step explanation:

When f(x) = 0

4 + 2x = 0

2x = -4

x = -2.

Ehen f(x) = 6

4 + 2x = 6

2x = 6-4 = 2

x = 1.

Which shows the correct substitution of the values a, b, and c from the equation 1 = -2x + 3x2 + 1 into the quadratic
lidiya [134]

Answer: A

Step-by-step explanation:

The first thing we need to do is to make sure our equation is in standard form. The given equation is not in standard form.

3x²-2x=0

Now that the equation is in standard form, we can find our A, B, C to see which quadratic equation is correct.

A=3

B=-2

C=0

We can automatically eliminate D because the first value is -3 when it is supposed to be -(-2). Also, the denominator is supposed to be 2a. We know that A=3. The denominator should be 2(3), not 2(-2).

Next, we can eliminate B and C. For the 4ac, we know it has to be 4(3)(0) because A=3 and C=0. B and C have given 4(3)(2) and 4(3)(1), respectively. This does not match A=3 and C=0.

Therefore, A is the correct answer.
