Answer: y = x^2 - 2 does not represent a linear function because the squared exponent above the variable makes that equation quadratic. Quadratic equations look like parabolas on a graph, rather than lines.
The page gives you the information that 1 kg is equal to 1000 grams.
This means that you just need to multiply each kg by 1000.

67,436,828,104 rounded to the nearest million is 67,437,000,000. To round to the nearest million, you first check to see what is in the hundred-thousands place. If the number in the hundred-thousands place is a number between 0-4, the millions place stays the same. If the number in the hundred-thousands is 5-9, the millions place value goes up one.

Answer:
x = 96°
y = 102°
Step-by-step explanation:
Angles on a straight line add up to 180
78 + y = 180
y = 180 - 78
y = 102
Angles in a quadrilateral add up to 360
78 + 90 + x + x = 360
78 + 90 + 2x = 360
168 + 2x = 360
2x = 360 - 168
2x = 192
x = 192/2
x = 96°
