Answer:
a) The line intersects with the circle once.
b) Tangent
Step-by-step explanation:
We are given the following equation for the circle:
How many times does the line y=-6 intersect with the circle?
We have to find the values of x when
So
Since the line intersects the circle at one point, it is tangent to the circle.
The line intersects with the circle once.
Answer:
y = 10x + 100
Step-by-step explanation:
Given the information:
She earns the same amount per hour as she did in her old job $ 100 sign-on bonus
=> the equation for line p in the form y= mx where:
- x is the number of hour she worked
- y the money she earned
=> the equation for line q in the form y= mx + 100 ($ 100 sign-on bonus )
From that, we see that the two equations have the same slope or you can use a transformation to map line p onto line q
We can create two points (0, 0) and (2, 20) are on line p
<=> m =
The equation for line p is y = 10x
=>The equation for line q should include the hourly earnings at the
new job plus the sign-on bonus. The equation is y = 10x + 100
Hope it will find you well.
