Answer: y = -3.5x - 4.5
suppose: the equation of the line is y = ax + b ( a ≠ 0 )
because the line passes through (-2;2.5) => 2.5 = -2a + b
the line passes though (0;-4.5) => -4.5 = b
=> b = -4.5
2.5 = -2a + b
=> a = -3.5
b = -4.5
=> the equation of the line is y = -3.5x - 4.5
Step-by-step explanation:
4 hours = 50$
6 hours = 75$
10 hours = 125$
50 + 75 + 125 = 250?
I'm not sure if I understood your question, because you didn't say like "What is all of these times together?"
Answer:
B 12 pi m^2
Step-by-step explanation:
The area of the circle is pi r^2
We know the radius is 6
A = pi (6)^2 = 36 pi
The sector is 120 degrees. The entire circle is 360 degrees.
The fraction is 120/360 = 1/3
The sector covers 1/3 of the circle so it is 1/3 of the area
1/3 A = 1/3 (36 pi) = 12 pi
If I understand the question correctly, dots are written around the symbol to represent valence electrons, so 7 dots would be in the elements dot diagram. The element is in Group 17 with 4 other elements.
