-2 because in the second equation it is : 2x. If you multiply x in the first equation by -2 it will cancel out 2x in the second equation. -2x cancels out 2x. -2x+2x=0
Answer:
7
Step-by-step explanation:
because if you add 10+7 17 17+7=24
Here's the rule for working with these things:
There are 3 signs associated with a fraction:
=> the sign of the numerator
=> the sign of the denominator
=> the sign of the whole fraction; (if the fraction were in
parentheses, this sign would be written outside).
-- You can change any 2 of them without changing the value of the fraction.
-- Changing any 1 of them changes the effective sign.
___________________________________
Now, you said the fraction is negative.
So, let's start with the positive fraction, and see the different ways
that we could make it a negative fraction:
=> mark only the numerator negative
=> mark only the denominator negative
=> put parentheses around the fraction, and mark it negative outside
If you do any one of these things to a normal positive fraction,
it turns into a negative fraction.
Look at the choices you listed in the question:
-- in the numerator only ? Yes. That makes it a negative fraction.
-- in the denominator only ? Yes. That makes it a negative fraction.
-- both ? No. That makes it the same as a positive fraction.
-- put parentheses around the fraction, and a negative sign outside ?
Yes. This makes it a negative fraction.
-- it doesn't matter ? No. I hope you can see that it does matter.
Have I confused you ?
Is this more than you wanted to know ?
Answer:
Let width = l
Therefore, length = 3l
Perimeter = 2(l+b)
48 = 2(l+3l)
48 = 2× 4l
48 = 8l
8l = 48
l = 48/8
l = 6
Width = 6
Therefore, length = 3×6
= 18
Area = l×b
= 18×6
= 108

Explanation:</h2>
The complete question is:
_______________________________________
On the coordinate plane, Kyle graphs a line that represents a proportional relationship between x and y. Which point MUST be on the line?
A) (0, 1)
B) (1, 0)
C) (1, 1)
D) (0, 0)
_______________________________________
A proportional relationship between x and y can be written in a mathematical language as follows:
For any non-constan k-value. As you can see, this k-value represents the slope of a line. Remember that the Slope-intercept form of a line is given by:
In the case of the y-intercept is zero, so the line passes through.
In conclusion, <em>Kyle's graph is a line that represents a proportional relationship between x and passes through point (0, 0)</em>
