Answer: B
Reason:
44 + x

Also when we have a greater and equal to sign (
), it will be a filled in circle.
Thats why its by.
First, simplify the radicals
√125=√(5*5*5)=(√5*5)(√5)=5√5
so 3√125=3*5√5=15√5
and √16=4
so
15√(5)-4 is the simplified version
Answer:
relation ( but not a function)
Step-by-step explanation:
Answer:
(0, -14)
Step-by-step explanation:
The y intercept of the graph of the function is at (0, -14)
In the equation y = mx + b, the constant b is the y value of the y intercept. In this equation, b is equal to -14, so this means the y intercept is at (0, -14).
We can also find the y intercept by setting x equal to 0, then solving for y.
Substitute 0 for x:
y = -7x - 14
y = -7(0) - 14
y = 0 - 14
y = -14
So, the y intercept is at (0, -14)
