Answer:
x=-3
Step-by-step explanation:
what is the equation?
Answer:
-4x -10x
See both terms contain a common multiple x
and HCF of 4 and 10 is 2
So, take -2x common
-2x( 2 +5)
= -2x(7)
=-14x
Answer:
16/13 is the answer.
26-10 is 16 and 2x5+3 is 13
-x + 5y = 8....we need to put this in y = mx + b form to find the slope...the slope will be in the m position.
5y = x + 8
y = 1/5x + 8/5.....so the slope is 1/5...a perpendicular line will have a negative reciprocal slope. So the slope we need is -5.
y = mx + b
slope(m) = -5
(7,-1)..x = 7 and y = -1
now we sub and find b, the y int
-1 = -5(7) + b
-1 = -35 + b
-1 + 35 = b
34 = b
so ur perpendicular line is : y = -5x + 34
the original slope was 1/5...a parallel line will have the same slope
y = mx + b
slope(m) = 1/5
(7,-1)...x = 7 and y = -1
now we sub and find b, the y int
-1 = 1/5(7) + b
-1 = 7/5 + b
-1 - 7/5 = b
-5/5 - 7/5 = b
-12/5 = b
so ur parallel line is : y = 1/5x - 12/5
The answer to your question is 1.5
