Answer:
The value of x is 7.
Step-by-step explanation:
First, you have to make the left side into 1 fraction by making the denormintor the same and make it into simplest form :
Next you have to multiply both sides by 2 in order to make x the subject :
Answer:
c=12
Step-by-step explanation:
12c - 53= 91
12c=144
c=12
Answer:
<u><em>45/49</em></u>
Step-by-step explanation:
You do the inverse operation so 7/15=15/7. 15/7×3/7= 45/49. You can't simplify it any further so it is 45/49.
Perpendicular lines will have negative reciprocal slopes. What that means is if u have a slope of 1/2, to find the negative reciprocal, flip the slope and change the sign.......flip 2/1, change the sign -2/1 or just -2. So the negative reciprocal for the slope of 1/2 is -2.
A. y = 1/5x + 3.....slope here is 1/5, so for a perpendicular line, u r gonna need an equation with the slope of -5.....and that would be : y + 3 = -5(x + 2).
B. Parallel lines will have the same slope. y = 5x - 2...the slope here is 5...so a parallel line will have a slope of 5.
y = mx + b
slope(m) = 5
(8,-2)...x = 8 and y = -2
now we sub, we r looking for b, the y intercept
-2 = 5(8) + b
-2 = 40 + b
-2 - 40 = b
-42 = b
so ur parallel equation is : y = 5x -42
