1) 3x – 2y = 2<br>y = 2x + 8<br>alguien que me ayude con esto no lo entendemos gracias

shusha [124]

{ 3x-2y=2
{ y=2x+8

{ -2y=2-3x
{ y=2x+8

{ y= -1+3/2x
{ y= 2x+8

-1+3/2x = 2x+8
x=-18

y= 2(-18)+8
y= -28

(x,y) = ( -18,-28)

——
Solution check

{ 3(-18)-2(-28)=2
{ -28=2(-18)+8

{ 2=2
{ -28=-28

Solve the system. Enter the smallest x-coordinate first

pentagon [3]

$y= 3 \,\,,\,\,x= -2 \,\,and\,\, y=3\,\,,\,\, x=2$

Step-by-step explanation:

Solving the following system of equations:

$x^2-y=1\\2x^2+y^2=17$

Let

$x^2-y=1\,\,\,(1)\\2x^2+y^2=17\,\,\,(2)$

Putting value of x^2 in eq(2)

$x^2 = 1+y\\Putting\,\,value\,\,of\,\,x^2\,\,in\,\,eq(2)\\2(1+y)+y^2=17\\2+2y+y^2=17\\y^2+2y+2-17=0\\y^2+2y-15=0\\Factorizing:\\y^2-3y+5y-15=0\\y(y-3)+5(y-3)=0\\(y+5)(y-3)=0\\y+5=0 \,\,and \,\, y-3=0\\y = -5 \,\,and \,\, y=3$

Now, finding value of x

Putting y=-5

$x^2 = 1+y\\x^2=1-5\\x^2=-4\\Taking\,\,square\,\,root\\x= \pm2i$

y=-5, x= 2i and y=-5 , x= -2i

Since we need to find x and y coordinates and its value cannot be in terms of i so we will not consider these as answer

Putting y=3

$x^2 = 1+y\\x^2=1+3\\x^2=4\\Taking\,\,square\,\,root\\x= \pm2$

So, $y= 3 \,\,,\,\,x= -2 \,\,and\,\, y=3\,\,,\,\, x=2$

a number n is 25% of some number a and 35% of a number b. is a > b,a<, or is it impossible to determine the relationship

Anit [1.1K]

Answer: "It is IMPOSSIBLE to determine the relationship."
_________________________________________________________
Because number "a" could be "30" ; and number "b" could be: "6 trillion"; for example. Or, number "a" could be "6 trillion" and number "b" could be "30".

OR; "a" could equal "b" ; for example.

Travis is filling a bathtub with water. He made a table showing the number of gallons of water in the bathtub based on the numbe

AleksAgata [21]

Lol another one?

So I looked at the graphs and the only one that actually even reaches 75 is the dotted one on the left. The one in the middle obviously doesn't go anywhere and the one on the right goes to 65, not 75.
