Answer:

10( 3/4x  * 9/500y ) = 10  

Step-by-step explanation:

We know 18% can also be found

when we take the x amount 75 x 0.18 = 13.50

We thereafter find 75-13.50 = 61.50 for Janella's hair cost plus $13.50 tip.

But for x = 750 x 9/500 = 10

We find  13.50 = 10

x= 1.5

18% coincidentally is 13.5 and 13.5 x 1.5 = 18

So we could redesign and use 18 in the equation

What is the domain of the relation?
Thepotemich [5.8K]

Answer: -4

Step-by-step explanation:

Domain: x-axis

Range: y-axis

The relation graph shows the points in which the domain is located. To find the Domain, go to the point in the x-axis (the horizontal line) and note the number where the point lies. For this question, the point on the left side of the graph lies on negative four (-4), and on the right side, the point is on 6. Therefore, the domain of this relation is negative four is greater than/equal to x is less than/equal to six. It could also be written like this: -4\leq x\leq 6.

Is (-1,4) a solution of the inequality y<2x+5?
Sveta_85 [38]
Let's plug x= -1, y= 4 in the inequation, we have:
4< 2*(-1)+5
⇒ 4< -2+5
⇒ 4< 3 (false)

Therefore, (-1,4) is not a solution of the inequation y<2x+5~

What value of x is in the solution set of –5x – 15 &gt; 10 + 20x?
Shalnov [3]

HI Brainiac


-5x-15 > 10+20x

-5x-20x > 10+15

-25x > 25

Divide both sides by -25

-25x/-25 > 25/-25

x < -1

Answer : B


I hope that's help:)
