Answer:
30x + 45
Step-by-step explanation:
multiply 5 times 6x
30x
multiply 5 times 9
45
you cannot add 30x and 45
Answer:
Yes, the relationship between x and y is a non-linear function.
Step-by-step explanation:
Given the table
Edge Length, x Surface Area, y
1 6
2 24
3 54
4 96
- The table values clearly represent a function, because each input value has one and only one output value. i.e. there is no repetition of x values.
- Also from the table values and the graph, it is clear that the function is not a linear function, because the graph is not a straight line. Also, In a cubic function, the highest power over the x variable(s) is 3. So, it is not a linear function.
Hence, we conclude that Yes, the relationship between x and y is a non-linear function.
Therefore, the 'last option' is correct.
Answer:
30° and 60°
Step-by-step explanation:
Complementary angles sum to 90°
let 1 angle be x then the other angle is 0.5x ( half as large ), then
x + 0.5x = 90
1.5x = 90 ( divide both sides by 1.5 )
x = 60
Hence angles are x = 60° and 0.5x = 30°
