Hello
so when finding a parallel line both lines need to have the same slope, the slope of the line from the given equation is -2.
then we use the point slope formula to find the equation of the line that passes through (1,5).
y-5=-2(x-1)
y-5=-2x+2
y=-2x+7
hope this helps!
have a nice day :)
So Sahra is 3 times as old as her daugter. That means that the sum of their age is the daughters age times 4.
We can prove that by saying the daughters age is x. Sahra's age must be 3x. Their sum must be x+3x = 4x.
So to get the daughters age we divide the sum by 4, which is 8.
Answer:
We just add numerators and rewrite denominator.
Adding unlike dominators:
We need to find the same denominators. You need to find the least common multiple (LCM) of the two denominators.
Step-by-step explanation:
You mean unlike denominators and like denominators.
Adding like dominators: We just add numerators and rewrite denominator :
Example : 
Adding unlike dominators:
We need to find the same denominators. You need to find the least common multiple (LCM) of the two denominators.
For example :

LCM for 5 and 4 is 20 : Now, divide by 5 and multiply by 1 for first fraction. 20 divide by 4 and multiply by 3 :

Answer:
$38.29
Step-by-step explanation:
Answer:
-3
Step-by-step explanation:
if x= -3
the denominator becomes 0 and the fraction becomes undefined.
