Answer:
13.8
Step-by-step explanation:
the required constant can be calculated as:
according to the formula above:
I’m not sure...but I think
x+y=5
If x =15
Then 15+y=5
Y= 10
The 2nd robot can do the task in 10min
Answer:
x = -2
Step-by-step explanation:
The line x = - 5 means it is a straight vertical line that has no slope. This means that the slope is undefined.
Now, for this line to be parallel to the line passing through point P(−2, 6), it means the line will be a vertical line too with the equation of form (x = a).
Thus, the equation of the line is x = -2
Pounds of butter=1/10 (potatoes)
=1/10 (12.5)
=1.25 pounds
Ellie uses 1.25 pounds of butter
Complete the square for the given equation
x² - 2x + ____ + y² - 2y + _____ = 98
x² - 2x + (1) + y² - 2y + (1) = 98 + (1) + (1)
(x - 1)² + (x - 1)² = 100
(x - 1)² + (x - 1)² = 10²
Now the equation is in the form (x - h)² + (y - k)² = r²
Radius = 10
