Answer: The approximate value of x is -3.396

Step-by-step explanation:

Given:

Now,to find the value of x.

Use logarithm rule:

We have,

Now,

Using value of: and we get,

on simplify:

Adding 1 both the sides, we get

Therefore, the approximate value of x for the equation is -3.396.

Stores X, Y, and Z each sell a certain item that has a given list price. Stores X and Y are located in a state with a 5 percent

hram777 [196]

Answer:

B. x=y

Step-by-step explanation:

A 5% tax charge is equivalent to multiply the current price by 1.05. On the other hand, a 5% discount is equivalent to substrace the current the 5% of it, so in the end, you multiply the current price by 0.95.

For X we should multiply first by 0.95, then by 1.05

For Y we multiply first by 1.05, then by 0.95

Hence, if L = price list, we have

x = L*0.95*1.05 = 0.9975L
y = L*1.05*0.95 = 0.9975L
z = L

As a result, x=y<z. Option B is correct.

Note that applying discount first or charging taxes first doesnt matter because the order of the factors doesnt ater the product.

Solve for x<br> y=<img src="https://tex.z-dn.net/?f=%20%20%5Cfrac%7Bx-v%7D%7Bb%7D%20" id="TexFormula1" title=" \frac{x-v}{b} "

Y = $\frac{x - v}{b}$ Multilpy both sides by b
yb = x - v Add v to both sides
yb + v = x Switch the sides to make it easier to read
x = yb + v

What is an equation that represents the line that passes through the point (-2, 2) and is parallel to

asambeis [7]

Answer:

$y = \frac{1}{3}x + 3$

Step-by-step explanation:

The slope of two parallel straight lines are the same.

Now, the slope of the line $y = \frac{1}{2} x + 8$ is $\frac{1}{2}$ as the straight line equation is in slope-intercept form.

Now, the equation of the straight line in slope-intercept form which is parallel to the above line is $y = \frac{1}{2} x + c$ ............. (1) , where c is any constant.

Now, point (-2,2) is on the line (1) {Given}

So, this point will satisfy the equation.

Hence, $2 = \frac{1}{2} (- 2) + c$

⇒ c = 3.

Therefore, the equation of the required straight line is $y = \frac{1}{3}x + 3$ (Answer)
