Answer:
The answer is: y = 1/2x + 2
Step-by-step explanation:
Given equation: y = 1/2x + 5
Given point: (-2, 1)
The slope of the given line is 1/2. Parallel lines have the same slope.
Use the point slope form and solve for y:
y - y1 = m(x - x1)
y - 1 = 1/2(x - (-2))
y - 1 = 1/2(x + 2)
y - 1 = 1/2x + 1/2 * 2
y - 1 = 1/2x + 1
y = 1/2x + 2
Proof:
f(-2) = 1/2(-2) + 2
= -1 + 2
= 1, giving point (-2, 1)
Hope this helps!! Have an Awesome Day!! :-)
Answer:12/7
Step-by-step explanation:
-9 2/7 -(-10 3/7)
(7x-9+2)/7+10 3/7
(7x-9+2)/7+(7x10+3)/7
-61/7+73/7
(-61+73)/7=12/7
Real numbers
2.77 is not a natural number (counting numbers 1, 2, 3, ...)
2.77 is not a whole number (non-negative integers 0, 1, 2, 3, ...)
2,77 is not an element of null set as a null set has no elements.
{5, 7, 9}
The elements 5, 7 and 9 are elements of set D and they are also elements of set E.
