Answer and Explanation

__________________________________________________________

<h2>The equation has infinitely many solutions.</h2><h3>( x = an infinite amount of numbers )</h3>

__________________________________________________________

We can prove this by using multiple numbers into the equation.

Let me show you what I mean.

__________________________________________________________

$3\left(2x+1\right)=8x+2-2x+1$

__________________________________________________________

$3\left(2\cdot2+1\right)$ = $15$ ( in this case, x = 2 )

$8\cdot2+2-2\cdot2+1$ = $15$ ( so, x can equal 2, but I checked again if there are multiple answers. )

__________________________________________________________

$3\left(2\cdot8+1\right)$ = $51$ ( in this instance, x = 8 )

$8\cdot8+2-2\cdot8+1$ = $51$ ( since x = 8 and can equal anything else, my conclusion is, that there are infinitely many solutions. )

Hope this helps! <3

Answer:
$\frac{x^2 - 5}{4x + 1}$ , x ≠ -1/4

Explanation:
We are given that:
f (x) = 4x + 1
g(x) = x² - 5

We want to find the value of (g/f)(x). This means that we will simply divide g(x) by f(x) as follows:
$( \frac{g}{f} )(x) = \frac{g(x)}{f(x)} = \frac{x^2 - 5}{4x + 1}$

Now, we should note that any function is undefined if its denominator is equal to zero.
This means that for our current function:
4x + 1 cannot be equal to zero
4x + 1 = 0
4x = -1
x = -1/4
This means that the value of x cannot be -1/4, otherwise, our function would be undefined.

Based on the above, the last option is the correct one.

Hope this helps :)

If three pears and four oranges cost $4.85 and three pears and ten oranges cost $8.75 what is the cost of a pear and an orange

marishachu [46]

Answer:

1 pear = $0.75; 1 orange = $0.65

Step-by-step explanation:

(1) 3P + 4O = 4.85

(2) 3P + 10O = 8.75 Eqn (2) - Eqn (1)

3P + 10O – 3P – 4O = 8.75 – 4.85 Combine like terms

6O = 3.90 Divide each side by 6

O = $0.65 Substitute into Eqn (1)

3P + 4×0.65 = 4.85

3P + 2.60 = 4.85 Subtract 2.60 from each side

3P = 2.25 Divide each side by 3

P = $0.75

Oranges cost $0.65 each and pears are $0.75 each

The side lenghts of a triangle are 14,15, and x units

iragen [17]

9514 1404 393

Answer:

1 < x < 29

Step-by-step explanation:

The triangle inequality requires the sum of the two shortest sides exceed the longest side.

When x and 14 are the shortest:

x + 14 > 15

x > 1

When 14 and 15 are the shortest:

14 +15 > x

29 > x

Then the requirement for the length of x is ...

1 < x < 29

_____

Additional comment

The length of the third side of a triangle can be between the difference and sum of the two given sides.

Z=(x-u)/q slove for x

frosja888 [35]

Answer:

zq+u =x

Step-by-step explanation:

z=(x-u)/q

Multiply each side by q

zq = (x-u)/q *q

zq = x-u

Add u to each side

zq+u = x-u+u

zq+u =x
