Answer:
Answer is D
Step-by-step explanation:
The first thing you should know is that the rate of each one is:
Kaitlyn = 1/6
Mark = 1/8
Then,
d = number of days.
The equation then if they work together is:
1 / 6d + 1 / 8d = 1
answer:
the equation for number of days it would take to build the sheld together is
1 / 6d + 1 / 8d = 1
Answer: x = 0; x=10

Answer:
See explanation below for all parts
Step-by-step explanation:
Your current slope (m) is -1/2 (the orange colored slope) so the "opposite" slope would be 2/1 or 2(the blue colored slope)
The answer for number 3 is y=2x+b.
For number 4, plug in the point values for x and y and solve for b. The point given is (-4,-5).
-5=2(-4)+b Now simplify
-5=-8+b then add 8 to both sides to isolate b
3=b or b=3
For number 9, you now know that m is 2 and b is 3
y=2x+3
Diameter: The length of the circle
Radius: Half of the diameter
If the diameter of the circle is 14 inches, the radius would be 7 inches as the radius is half the diameter
