Answer:
y = -19
Step-by-step explanation:
The equation has a negative slope (-3). This means the y value decreases as x increases. Since the maximum value for x is 5 (≤5), we know that the value produced when x = -5 will result in the smallest value of y.
In this case,
y = -3x - 4
y = -3(5) - 4
y = -19
See attached graph.
Yes it is a function because there are not any repeating x values ( first number in each set of parentheses)
Answer:
x-7>0
Straight answer: x-7
Step-by-step explanation:
Assuming that the timber is X cm long and 7cm was cut off, there remaining amount is x - 7cm. In order for 7cm to be cut off, the timber must have been > 7cm long => x > 7 => x - 7 > 0
Answer: The function is (f/g) (x)=2x+9. The domain of f/g is all real numbers except for x=8 because the denominator is 0 when x=8
