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
The answer would be 6.2 then 7
8n + 12 +(-9) -(-6n)
12 + -9 = 12-9 = 3
8n - (-6n) = 8n + 6n = 14n
The equation becomes 14n + 3
20,817.92 rounded to the nearest dollar is 20.818
Answer:
The first one is linear the rest isn't
Step-by-step explanation:
A linear function represent a straight line.
The first one shows that.
The second function look more like a tangent function which is a trig function so it isn't linear. The third one is a exponential function which is definitely not linear.
