Yeah, plus it says the y-intercept is a positive 2 so you would add 2 in the equation, so what u have is correct.

X+y-2.
Translate to slope intercept form( y=mx+b then it becomes y= -x +2

Kirti knows the following information from a study on cold medicine that included 60 participants: 30 participants in total rece

GalinKa [24]

The frequency table is attached.

Since there were 30 people out of the 60 that received cold medicine, that means that 60-30=30 people did not.

Since 26 people had a cold longer than 7 days, this means 60-26=34 had a cold that was less than or equal to 7 days.

14 people had a cold longer than 7 days and received medicine; this means that 26-14=12 people had a cold longer than 7 days and did not receive medicine.

30-14=16 people received medicine and had a cold less than or equal to 7 days.

30-12=18 people did not receive medicine and had a cold less than or equal to 7 days.

A total of 937 people attend the play. Admission was $2.00 for adults and $0.75 for students. The totral ticket sales amounted t

a_sh-v [17]

Answer:

x = students

y = adults

Linear Systems of Equations :

x + y = 937

0.75x + 2y = 1,109

Step-by-step explanation:

Step 1 : eliminate one of the variables

x + y = 937

0.75x + 2y = 1,109

-2(x + y = 937) = -2x - 2y = -1874

-2x - 2y = -1874

0.75x + 2y = 1109

We can eliminate y since -2y + 2y = 0

Step 2: Find x number of students.

-2x = -1874

+0.75x = 1109

____________

-1.25x = -765

____________ = 612 students attended

-1.25

937 - 612 = 325 adults

Check Answer :

612 x 0.75 = $459

325 x 2 = $650

$650 + $459 = $1,109

Therefore, there will be 612 students attending and 325 adults.

Answer:

1.1, 12, 99

Step-by-step explanation:

For the first one, we divide 2.5 by 2.2 (2.5/2.2) to get approximately 1.1 kilograms. So it would be the first option. For the second one, we know that 8x6=48, so we multiply 2 by 6 to get 12/48, so it would be the second option. For the third one, we can do this problem: 110/20 to get 5.5. We can multiply 18 by 5.5 to get 99. So that means the answer would be the first option.
