Answer:

Fraction: 1/ 5 n= 7

Step-by-step explanation:

To find n first you cross multiply : 2/ 10 * n / 35

= So we multiply 10 and n ( answer = 10n)

= Then 2 and 35 ( multiply) ( answer = 70)

Now algebra

70 = 10n

Divide both sides by 10

10n / 10 = 70 / 10

n = 7

The fraction becomes 7 / 35

When this is simplified the answer is 1 / 5

To simplify you divide the numerator and denominator of the fraction by 25 ( GCF )

F(z) = (z - 5)(2x + 7) (73 = 3) has zeros at x = -3.5, x=3/7 , x=5 What is the sign of f on the interval 3/7 < x <5?
Gwar [14]
<h3>Answer:     Negative</h3>

======================================================

Explanation:

3/7 = 0.42857 approximately

Pick a number between that value and 5, not including either endpoint. Let's say we pick x = 2

Plug x = 2 into the f(x) function

f(x) = (x - 5)(2x + 7)(7x-3)

f(2) = (2 - 5)(2*2 + 7)(7*2-3)

f(2) = (2 - 5)(4 + 7)(14-3)

f(2) = (-3)(11)(11)

f(2) = -363

The actual result doesn't matter. All we're after is whether the result is positive or negative. We see the result is negative. This means f(x) is negative when 3/7 < x < 5. The f(x) curve is below the x axis on this interval.
