Consider the following pair of equations:

1 answer:

6 0

So the equations are:

y= 3x + 3

y= x- 1

By the transitive property, we know x-1= 3x+3 (Transitive property means if a= b, and b= c, shouldn't a = c if they both equal b?)

so, x- 1= 3x + 3. Now we isolate x and solve:
+1 +1
x= 3x+ 4
-x -x

0 = 2x+ 4
-4 -4

-4 = 2x
/2 /2

x= -2

Now, you can plug that back in to find y:

y = x- 1
y= -2 -1
y= -3

Then plug them both in to make sure it is correct. :o)

For the equation y - x < 0,
y < x
The shaded portion will be under the dashed line joining points (-2, -2) and (3, 3).

for the equation x - 1 > 0,
x > 1
The shaded portion will be to the right of the dashed line joining points (1, 5) and (1, -3).

The portion affected by the two shadings will be the portion common to the right of the dashed line joining points (1, 5) and (1, -3) and under the dashed line joining points (-2, -2) and (3, 3).
Therefore the correct answer is option c.

What is the solution to the system of equations y23x3 x 2

bija089 [108]

The Solution for the given system of equations is (-2) and $(\frac{5}{3})$ .

The given are linear equations as follow:
y = $\frac{2}{3}x$ + 3 .. ... ...(1)
and x = -2. .. .... ...(2)

We already know the first part of the solution (x) which is -2. We can find the other part (y) by putting the value of equation (2) in equation (1).

By putting the values of x in equation (1), we get

y = $(\frac{2}{3})(-2)$ + 3
y = $\frac{-4}{3}$ + 3

Taking the L. C. M of denominators which will be '3', we get:

y = $\frac{-4 + 9}{3}$

y = $\frac{5}{3}$

So the second part (y) of the solution of the given equation is $\frac{5}{3}$ .

Hence, the overall solution to the given system of equation is $(-2, \frac{5}{3})$ .

there are 27 red or blue marbles in the bag the number of red marbles is five less than three times the number of the blue marbl

alexdok [17]

So assuming that the total =27
r+b=27
r=-5+3b
r=3b-5
subsitute 3b-5 for r in first equation
3b-5+b=27
4b-5=27
add 5
4b=32
divide by 4
b=8
subsitute
b+r=27
8+r=27
subtracct 8
r=19

red=19
blue=8

17. Find the reflection of the point A(6.-1) in the x-axis.<br>

castortr0y [4]

Answer:

Your answer will be (6,1)

Step-by-step explanation:

I know this because a reflection over the x-axis is (x,y) -> (x,-y) If you apply this to (6,-1) you get (6,1).
