Answer:
(-1, 3)
Step-by-step explanation:
Add the two equations together:
(7x - 2y) + (2y - 5x) = -13 + 11
Simplify:
2x = -2
x = -1
Plug x=-1 into the first equation:
7(-1) - 2y = -13
-7 - 2y = -13
-2y = -6
y = 3

Select all of the ordered pairs (x,y) that are solutions to the linear equation 2x+3y=6. Substitute the x and y values into the equation above to see if the ordered pair is a solution to the linear equation.
Answers
Answer:
1. Not a solution
2. Not a solution
3. Not a solution
4. Not a solution
5. A Solution
6. A solution
Step-by-step explanation: 5 is correct because it is 3 times 2 so 6, but there is no y so the final answer is 6. And the last one is 6 x 2 = 12 and then -2 x 3 = - 6, so 12 - 6 = 6.
Hope this helps
Answer:
The fifth and sixth answer are solutions.
Step-by-step explanation:
If you substitute the x and y values, essentially multiplying them by the already existing coefficents, you realize that a lot of the equations do not equal 6.
The last two however, do.
Rewrite without absolute value for the given condition: y=|10-x|, if x<10
Answers
Answer:
The answer is 10-x
Step-by-step explanation:
The absolute value of the equation is given by y = 10 - x
What is Modulus Function?Regardless of the sign, a modulus function returns the magnitude of a number. The absolute value function is another name for it.
It always gives a non-negative value of any number or variable. Modulus function is denoted as y = |x| or f(x) = |x|, where f: R → (0,∞) and x ∈ R.
The value of the modulus function is always non-negative. If f(x) is a modulus function , then we have:
If x is positive, then f(x) = x
If x = 0, then f(x) = 0
If x < 0, then f(x) = -x
Given data ,
Let the modulus function be represented as A
Now , the value of A is
y = | 10 - x | be equation (1)
Now , the absolute value of the function when x is less than 10 is
when x < 10
y = | 10 - x |
y = 10 - x
Hence , the value of absolute function is y = 10 - x

what is the value of y?
also pls include an explanation for this along with a check ( a sentence to check the answer ) and property ( commutative, associative, distributive, or identity ) ;-; ill give 5 stars and a thanks
Answers
Answer:
2.1
Step-by-step explanation:
You divide 8.4 by 4 hope this helps
=========================================================
Work Shown:
4y = 8.4
4y/4 = 8.4/4 .... divide both sides by 4; division property of equality
y = 2.1
---------------
Check:
4y = 8.4
4*2.1 = 8.4 .... replace y with 2.1
8.4 = 8.4
We end up with a true equation, as we get the same number on both sides, so we've confirmed the answer.

What is the y-intercept?
What is the x-intercept?
What is the slope of the line?
Find an equation for this line.
Answers
Answer:
Step-by-step explanation:
The "y intercept" is the point at which the graph intercepts the y-axis. In this case that point is (0, 20).
The "x intercept" is the point at which the graph intercepts the x-axis. In this case that point is (5, 0).
The slope of the line is m = rise / run. Here the "rise" is actually a drop from y = 20 to y = 0, so "rise" = -20. The "run" is the increase from x = 0 to x = 5, which is 5. Thus, m = the slope = -20/5 = -4. The slope is m = -4.
Given that we know the slope, m, of this line (m = -4) and two points on the line (use (0, 20) ), we can write the equation of the line immediately in point-slope form y - k = m(x - h), which in this particular case is
y - 20 = m(x - 0), or
y - 20 = -4x
Alternatively, we could put this into standard form: 4x + y = 20, or into
slope-intercept form: y = -4x + 20
