Answer:

y= -4

Step-by-step explanation:

Since x=1, then you would plug in 1 for x. 3 times 1 is 3, then you subtract 7 to get -4.

Daisy works at an ice-cream parlor. She is paid $10 per hour for the first 8 hours she works in a day. For every extra hour she
tester [92]

Answer:

The expression giving her net earnings for a day with more than 8 hours worked is X = 80 + 15H, where H means "extra hours worked".

Step-by-step explanation:

Given that Daisy works at an ice-cream parlor earning $10 per hour for the first 8 hours she works in a day, and 1.5 times her hourly wage for every extra hour she works, in order to know how much can she make in a day working more than 8 hours the following equation has to be made:

X = (8 x 10) + (H x (1.5 x 10))

X = 80 + 15H

Therefore, if Daisy works 13 hours, the equation works as follows:

X = 80 + 15x13

X = 80 + 195

X = 275

Which of the following points lie in the solution set to the following system of inequalities?
EastWind [94]

Answer:

Option c . (2, 5)

Step-by-step explanation:

we know that

If a ordered pair lie in the solution set of a system of inequalities, then the ordered pair must satisfy both inequalities of the system

we have

y > -3x+3 ----> inequality A

y >x+2 ----> inequality B

<u><em>Verify each ordered pair</em></u>

case a) (2,-5)

<em>Verify inequality A</em>

y > -3x+3

-5 > -3(2)+3

-5 > -3 ----> is not true

so

The point not satisfy inequality A

therefore

The point not lie in the solution set

case b) (-2,5)

<em>Verify inequality A</em>

y > -3x+3

5 > -3(-2)+3

5 > 9 ----> is not true

so

The point not satisfy inequality A

therefore

The point not lie in the solution set

case c) (2,5)

<em>Verify inequality A</em>

y > -3x+3

5 > -3(2)+3

5 > -3 ----> is true

so

The point satisfy inequality A

<em>Verify inequality B</em>

y >x+2

5 >2+2

5 >4 ---> is true

so

The point satisfy inequality B

therefore

The point lie in the solution set

case d) (-2,-5)

<em>Verify inequality A</em>

y > -3x+3

-5 > -3(-2)+3

-5 > 9 ----> is not true

so

The point not satisfy inequality A

therefore

The point not lie in the solution set
