Which expressions are equivalent to -6n + (-12) + 4n ?
raketka [301]
The expression equivalent to the fort is a) 4(n-3) -6n, if you so the math for the first one do what is inside the parenthesis first. (think PEMDAS) Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction. So the first thing it gives you is -6n +(-12) Well, a negative + a negative = a negative! So, -6+-12= -18, then add your caroable. So, -18n. Now, you add -18n with what you have left so 4n -18+4 is -14n. So, if you do answer a) (n-3) = (1n-3)= (1-3) =-2. -2×4=-8n because a negative × a positive = a negative because they have different signs. From there you have -8n - (6) Instead of subtracting you just add a negative So, you would rewrite your problem as: -8n+(-6)= -14n the same thing you got as your orginal. Hope tj
his helped! Don't forget about adding you variables and PEMDAS!! Also d po not forget about your positive a negative rules!!!

The linear equation y=3x−5y=3x−5 y equals 3 x , minus 5 is in what form.
Roman55 [17]
I must make some assumptions here about what you may have meant by your "<span>linear equation y=3x−5y=3x−5 y equals 3 x , minus 5."

You've written "y=3x-5" three times on the same line of type.  Why is that?  

Let's change what you've typed to the following:

</span><span>linear equation y=3x−5

separate linear equation y     equals 3x  minus 5, or y=3x-5 

Please go back and ensure that you have copied down this problem precisely as it was originally presented.  Be careful not to duplicate info (as you did in typing "y=3x-5," followed by  "</span><span>y equals 3 x , minus 5."
</span><span>
y = 3x - 5 is, as you say, "a linear equation."  The slope of this line is 3 and the y-intercept is (0, -5).

As to form:  This is a "slope-intercept equation of a straight line."

Other forms include "General form of the equation of a straight line," "Point-slope form."</span>

When rounded to the nearest 100 I am the smallest number that becomes 5000
SIZIF [17.4K]

Answer:

4950

Step-by-step explanation:

The smallest number when rounded to the nearest 100 that becomes 5000 should be between the range of 4950 and 4999.

To the round any figure to the nearest hundred, the \bold{tens digit} of the number should be considered. If the number ranges from 1 to 49, it should be rounded to previous hundred, but if the number is between the range of 50 to 99, it should be rounded to the next 100.

Therefore the smallest number when rounded to the nearest 100 that becomes 5000 is 4950
