System of Linear Equations entered :
[1] -2y-3y+z=-6
[2] x+y-z=5
[3] 7x+8y-6z=31
Equations Simplified or Rearranged :
[1] -5y + z = -6
[2] y - z + x = 5
[3] 8y - 6z + 7x = 31
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = -y + z + 5
// Plug this in for variable x in equation [3]
[3] 8y - 6z + 7•(-y +z +5) = 31
[3] y + z = -4
// Solve equation [3] for the variable z
[3] z = -y - 4
// Plug this in for variable z in equation [1]
[1] -5y + (-y -4) = -6
[1] -6y = -2
// Solve equation [1] for the variable y
[1] 6y = 2
[1] y = 1/3
// By now we know this much :
y = 1/3
z = -y-4
x = -y+z+5
// Use the y value to solve for z
z = -(1/3)-4 = -13/3
// Use the y and z values to solve for x
x = -(1/3)+(-13/3)+5 = 1/3
Solution :
{y,z,x} = {1/3,-13/3,1/3}

Step-by-step explanation:
verticle angles are congruent (the same) so if 1 is 110 than 4 is 110. also same side interior angles are supplementary (equal to 180) meaning 6 is 70. If verticle angles are congreunt then 7 also equals 70
-34x+6=-28
I need to learn how to solve for x
Answers
Answer:
x=1
Step-by-step explanation:
-34x+6=-28
-6 -6
-34x=-34
-34 -34
x=1
Subtract 6 from both sides. on the left the 6 will be canceled out and on the right -28-6= -34
Than you divide -34 on both sides on the left the -34 will be canceled and on the right -34 divided bt-34 is positive 1. So x equals 1.
Answer:
Your answer is x = 11/17
Step-by-step explanation:
I gotchu!
Alright first, subtract 6 on both sides. After doing so, your equation should look like:
-34x = + 22
Then, divide -34 on both sides. Do not divide x though! The equation will look like:
x= -22/34
Now, let's simplify the answer. We can divide 22 and 34 by 2 so we will do that.
After simplifying, it should be 11/17.
Finally, keep it improper because you always should keep fractions improper when doing this.
Your answer is x = 11/17
What are the coordinates of the image of the point (4,5) after reflecting over the y-axis
Answers
here is a link to the aneser hope it helps
The coordinates of the image of the point (4,5) after reflecting over the
the y-axis is (- 4, 5).
What are transformations?Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
Dilation: The preimage is scaled up or down to create the image.
Reflection: The picture is a preimage that has been reversed.
Rotation: Around a given point, the preimage is rotated to create the final image.
Translation: The image is translated and moved a fixed amount from the preimage.
Given, A point (4, 5) is reflected over the y-axis.
We know points of coordinated (x, y) reflected over the x-axis becomes
(- x, y).
Therefore, The coordinate points (4, 5) after reflecting over the y-axis would be ( - 4, 5).

Heather purchased a prepaid phone card for $15 . Long distance calls cost 16 cents a minute using this card. Heather used her card only once to make a long distance call. If the remaining credit on her card is $12.76 , how many minutes did her call last?
Answers
Answer:
14 minutes
Step-by-step explanation:
In order to get the answer, we have to subtract the original amount of money on the phone card by the amount left over after the call:
15 - 12.76 = 2.24
Then, we divide this number by 0.16:
2.24 / 0.16 = 14
So, Heather's call lasted 14 minutes

2.4(x - 6) = -5.6x + 8
Answers
Let's solve your equation step-by-step
2.4(x-6)=-5.6x+8
Step 1: simplify both sides of the equation
2.4(x-6)=-5.6x+8
(2.4)(x)+(2.4)(-6)=-5.6x+8 (distribute)
2.4x+-14.4=-5.6x+8
2.4x-14.4=5.6x+8
Step 2: Add 5.6x to both sides.
2.4x-14.4+5.6x=-5.6x+8+5.6x
8x-14.4=8
Step 3:Add 14.4 to both sides
8x-14.4+14.4=8+14.4
8x=22.4
Step 4 : Divide both sides by 8
8x/8 =22.4/8

Which equation represents the lower unit rate of these two relationships?

B. y=1/4x
C. y=1/5x
D. y=2/11
Answers
Answer:
the answer is d y=2
_ x
11
Step-by-step explanation:
I got it right on the test
2/11 is lower than 2/9, therefore the equation that will represent a lower unit rate (k) of both relationships given is: D. y=2/11
A proportional relationship between variable y and x can be expressed as:
y = kx
Where,k is the unit rate/constant of proportionality.
Therefore,k = y/x
Thus, find the equation for the table and the graph respectively in order to determine which equation represents the lower unit rate.
Equation for the table using a pair of coordinates, say (11, 2):
Find, unit rate (k) by substituting x = 11, and y = 2 into k = y/x
Thus:k = 2/11
Plug in the value of k = 2/11 into y = kx
The equation for the table is:
y = 2/11x
Equation for the graph using a point on the line, say (9, 2):
Find, unit rate (k) by substituting x = 9, and y = 2 into k = y/x
Thus:k = 2/9
Plug in the value of k = 2/9 into y = kx
The equation for the table is:y = 2/9x
In conclusion, 2/11 is lower than 2/9, therefore the equation that will represent a lower unit rate (k) of both relationships given is: D. y=2/11

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total number of beats be = A
Now , the value of A = 220 beats
The total time required for Sam to have 220 beats = 4 minutes
So , the number of beats of Sam in 1 minutes is calculated by
The equation will be
The number of beats of Sam in 1 minutes is = total number of beats / total time required for Sam to have 220 beats
The number of beats of Sam in 1 minute is = 220 / 4
The number of beats of Sam in 1 minute is = 55 beats per minute
Therefore , Sam would have 55 beats every minute or 55 beats per minute
And for the period of 4 minutes , Sam would have
Number of beats for 4 minutes = number of beats of Sam in 1 minute x 4
Number of beats for 4 minutes = 55 x 4
Number of beats for 4 minutes = 220 beats in 4 minutes
Hence , The equation for the number of beats per minute is 55 beats per minute

why do you multiply by 4/3 when you have 1/2x+2=3/4y when solving for y?
Answers
Step-by-step explanation:
You multiply by 4/3 because you are essentially "dividing" both sides by 4/3. You have to take the reciprocal of 3/4 which is 4/3 in order to cancel out the 3/4 because 4/3 x 3/4 will be 1. So the problem will look like this:
(1/2)x + 2 = (3/4)y
4/3[(1/2)x + 2] = 4/3 x 3/4y
4/3[(1/2)x + 2] = y
4/6 x + 8/3 = y
y = 2/3(x) + 8/3
And then from here, if they gave a value for x and y, you can solve for the 2 variables.
