Answer:

\large\boxed{\sf x = \frac{8y+1}{7} }

\large\boxed{\sf x = \frac{7x-1}{8} }

<u>Group the Variable's</u>:

2 x - 5 + 7 y - 3 = 9 x - 1 - y -8

2x -9x + 7y +y = -1 -8 +5 + 3

-7x + 8y = -1

<u><em>From this find x and y</em></u>

<u>For X</u>

-7x + 8y = -1

-7x = -1 -8y

7x = 8y + 1

x = (8y +1)/7

<u>For Y</u>

-7x + 8y = -1

8y = -1 +7x

y = (7x -1)/8

Tessa bought stock in a restaurant for $173.00. Her stock is now worth $242.20. What is the percentage increase of the value of
frozen [14]

Answer:

The percentage increase in Tessa's stock is 40%

Step-by-step explanation:

Given that:

Previous worth = $173

Worth now = $242.20

We have to find percentage increase which can be known by subtracting previous worth from present worth and multiplying it by 100:

Percentage increase = $242.20 - $173 = $69.2

Percentage increase = $69.2/173 *100

Percentage increase = 40%

Given triangle ABC with altitude segment AD labeled x. Angles ADB and CDA are _____1._____ by the definition of altitudes, makin
aleksandr82 [10.1K]

Answer:

Given triangle ABC with altitude segment BD labeled x. Angles ADB and CDB are right angles by _____1._____, making triangle ABD and triangle BCD right triangles. Using the trigonometric ratios sine of A equals x over c and sine of C equals x over a. Multiplying to isolate x in both equations gives x = _____2._____ and x = a ⋅ sinC. We also know that x = x by the reflexive property. By the substitution property, _____3._____. Dividing each side of the equation by ac gives: sine of A over a equals sine of C over c.

Examine the graph of the logarithmic function f(x).
Eduardwww [97]

Answer:

The function f(x) has a vertical asymptote at x = 3

Step-by-step explanation:

We can define an asymptote as an infinite aproximation to given value, such that the value is never actually reached.

For example, in the case of the natural logarithm, it is not defined for x = 0.

Then Ln(x) has an asymptote at x = 0 that tends to negative infinity, (but never reaches it, as again, Ln(x) is not defined for x = 0)

So a vertical asymptote will be a vertical tendency at a given x-value.

In the graph is quite easy to see it, it occurs at x = 3 (the graph goes down infinitely, never actually reaching the value x = 3)

Then:

The function f(x) has a vertical asymptote at x = 3

15 fewer than the quantity 222 times c equals c<br><br><br> Can you please write this as
vampirchik [111]
As an expression, this is: 
222c - 15 = c
If you want to solve it, add 15 to each side to get: 
222c = c + 15 
Subtract c from each side: 
221c = 15 
Divide each side by 221: 
c ≈ 0.0678733 
Hope this helps!
