(3,1) y= x -2, <span> when x = 3, y = 3 -2 = 1 ....YES
</span>(1,3) y= x -2 , when x = 1, y = 1 -2 = -1 ....NO
(-1,3) y= x -2 , when x = -1, y = -1 -2 = -3 ....NO
(3,-1) y= x -2 , when x = 3, y = 3 -2 = 1 ....NO

answer is

The easiest way to solve this problem is to start plugging in the values for y and x.

For "A" you have an x-value of 3 and a y-value of 1.  Plug these in and you get:

1 = (3) - 2.

Subtract.

1 = 1

Because this statement is true, "A" is a solution to the equation y = x - 2.

"A" is the answer.

If we were to try something else though, such as "B", we would end up with a false statement.

"B" has an x-value of 1 and a y-value of 3.

3 = (1) - 2

Subtract.

3 = -1

This statement is false, therefore, "B" is not a solution to the equation y = x - 2.

Answer:

General equation of line : y = mx+c   --1

Where m is the slope or unit rate

Table 1)

p    d

1      3

2     6

4     12

d = Number of dollars (i.e.y axis)

p = number of pound(i.e. x axis)

First find the slope

First calculate the slope of given points

m = \frac{y_2-y_1}{x_2-x_1}   ---A

(x_1,y_1)=(1,3)

(x_2,y_2)=(2,6)

Substitute values in A

m = \frac{6-3}{2-1}

m = 3

Thus the unit rate is 3 dollars per pound.

So, It matches the box 1 (Refer the attached figure)

Equation 1 : p=3d

\frac{p}{3}=d

Since p is the x coordinate and d is the y coordinate

On Comparing with 1

m = \frac{1}{3}

Thus the unit rate is \frac{1}{3} dollars per pound

So, It matches the box 2 (Refer the attached figure)

Equation 2 : \frac{1}{3}d=3p

d=9p

Since p is the x coordinate and d is the y coordinate

On Comparing with 1

m =9

Thus the unit rate is 9 dollars per pound

So, It matches the box 3 (Refer the attached figure)

Table 2)

p        d

1/9      1

1         9

2        18

d = Number of dollars (i.e.y axis)

p = number of pound(i.e. x axis)

(x_1,y_1)=(\frac{1}{9},1)

(x_2,y_2)=(1,9)

Substitute values in A

m = \frac{9-1}{1-\frac{1}{9}}

m = \frac{8}{frac{8}{9}}

m = 9

Thus the unit rate is 9 dollars per pound

So, It matches the box 3 (Refer the attached figure)

Mai says that the equation 2x+2=x+1 has no solutions because the left side is double the right side. Do you agree with mai provi
attashe74 [19]

Answer: No, Mai needs to solve the problem.

Step-by-step explanation:

2x+2=x+1 - subtract 2 from both sides

2x=x-1 - subtract x from both sides

x= -1 - solution

I need help with this one plz! (marking BRAINLIST) :) ​
FinnZ [79.3K]

Answer:

x=22

Step-by-step explanation:

the triangle in which x is in is an equilateral triangle.

44 is an exterior angle to that triangle.

an exterior angle is always equal to tbe sum of the opposite 2 interior angles.

because that triangle is equilateral

x =44 ÷ 2

x=22
