This is confusing but try doing f+5l=-8(x)
Answer:
(0,3)
Step-by-step explanation:
7x-2y=-6
8x+y=3
Multiply the second equation by 2 so we can eliminate y
2(8x+2y) = 2*3
16x+2y=6
Add the first equation to the modified second equation
7x-2y=-6
16x+2y=6
--------------------
23x = 0
Divide by 23
23x/23 = 0/23
x =0
Now we need to find y
8x+y = 3
0+y =3
y=3
(0,3)
Answer:
7x

Answer:
Y=X
Step-by-step explanation:
It depends on the context. No number besides 0 is given, so it can't really be the other ones with numbers.
Answer: Check out the filled out chart below.
Row 1: 1/4, 1/4, -4
Row 2: -2, -2, 1/2
Row 3: 3, 3, -1/3
=========================================
Explanation:
Parallel lines have equal slopes. So if the original line has slope 1/4, then any parallel line will also have slope 1/4. The only thing different is the y intercept.
Perpendicular slopes multiply to -1 assuming neither line is vertical. For row 1, the perpendicular slope is -4 which multiplies with the original slope 1/4 to get -1.
Put another way, the perpendicular slope is the negative reciprocal of the original slope. For row 2, the perpendicular slope is 1/2 because we flip the fraction and the sign for the original slope -2 = -2/1
