Answer:

x=1, y=6

(1,6)

Step-by-step explanation:

First we must isolate one of the variables (x or y) in one of the equations (First or second). Here I'll isolate y in equation 2 since it's the easiest to solve.

$-2x+y=4\\y=4+2x$

Now that we have successfully isolated, we will next substitute the chosen variable (y) in the opposite equation (Eq 1) with the equation we have recently formed:

$2x+3y=20\\2x+3(4+2x)=20\\2x+12+6x=20\\8x+12=20\\8x=8\\x=1$

Next substitute x in the opposite equation: (basically the equation we previously used to create a new equation which is Equation 2)

$-2x+y=4\\-2(1)+y=4\\-2+y=4\\y=6$

Answer:

Step-by-step explanation:

10y2 - 17y + 12 = y + 16

10y2 - 17y + 12 - 16 = y

10y2 - 17y - 4 = y

10y2 -17y - y -4 = 0

10y2 -16y - 4 = 0

Now put formula

x = -b +- (square root) b2 - 4ac

a = 10 b= -16 c= -4

y = -(-16) +- (square root) -16 - 4 (10) (-4)

2(10)

y = 16 +- (square root) -16 - 400

y = 16 +- (square root) -416

y = 16 +- 20.396

Now this +- is the plus minus thingy in which two answers come

The first we will do is +

16 + 20.396 16 - 20.396

20 20

= 1.8198 = -0.2198

150 students were surveyed on how many text messages to send in a date for different devices. let X represent the number of stud

kakasveta [241]

Given that the total number of students that sent messages = 150 students

a) To obtain the equation to represent the number of students who send text messages, we will sum up the variables in the Venn diagram and equate it to 150.
