Answer:
B
Step-by-step explanation:
If you're concerned with the points -2 and -5, you would be looking for a number line with those points plotted on it. The only one is ...
number line B
7]
6/(x-1)-5x/4
subtracting the above we put the fraction under the same denominator:
6/(x-1)-5x/4
multiplying the denominators we get:
4(x-1)
thus subtracting we get:
6/(x-1)-5x/4
=(4*6-5x(x-1))/[4(x-1)]
=[24-5x^2+5x]/(4x-4)
Answer:
(-5x^2+5x+24)/(4x-4)
9]
3/(x+7)+4/(x-8)
the common denominator is:
(x+7)*(x-8)=(x+7)(x-8)
thus adding the fractions we put them under the same denominator as follows:
[3(x-8)+4(x+7)]/[(x+7)(x-8)]
=[3x-24+4x+28]/[(x+7)(x-8)]
=(7x+4)/[(x+7)(x-8)]
Answer:
7.5 or 15/2 (Whatever form you need to use)
Step-by-step explanation:
N-5 divided by 2 =5
Combine like terms:
-5 divided by 2= -2.5.
N-2.5=5
Add -2.5 from itself, then do the same to the other side:
N-2.5=5
+2.5=+2.5 (Adding 2.5 to -2.5 cancels it out)
N=7.5
2 is your answer duuuuuuuuuuuude
