Answer:
Step-by-step explanation:
A linear equation in "standard form" looks like Ax + By + C = 0, or
Ax + By = D
x + y = -1
: is in standard form: A = 1, B = 1 and D = -1
-3.x = y
: NOT in standard form
x + 4y = 0 is in standard form
y = 5x - 2 NOT in standard form
x = 3 -0.17 NOT
8x – 3y = 20 is in standard form
Answer:
its thrid one
Step-by-step explanation:
Answer: x = 4.6
Step-by-step explanation:
From the diagram opposite is 4
Adjacent is x
@ = 41 degrees.
Solve from SOH CAH TOA
From here the one that has opposite and adjacent is TOA which is;
[email protected] = opposite/ adjacent
[email protected] = 4/x
x = 4/[email protected]
x = 4/tan 41
x = 4/0.869
x = 4.6
For this question you need to coordinate geometry to find the distance between the coordinates then find the perimeter
