which equation represents a linear function? equation 1: y = 2x2 1 equation 2: y2 = 3x 1 equation 3: y = 5x – 1 equation 4: y =
1 answer:
linear means first degree
first degree means the hightest exponent of the variables is 1
so
equation 1:
highest exponent is 2, not 1
not leinear
equation 2: y^2=3x+1
highest exponent is 2, not 1
not linear
equaton 3 y=5x-1
y=5x^1-1, it is 1
it is linear
equaton 4
y=4x^4-1
highest is 4, not 1
not linear
answer is equation 3: y=5x-1

Answer:
Step-by-step explanation:
13).
q ≤ 7
14). -12x < 60
12x > -60
x > -5
15). 5 > z - 3
5 + 3 > z - 3 + 3
8 > z
16). 0.5 ≤
0.5 × 8 ≤
4 ≤ y
Now we can draw these inequalities on a number line.
