D because those options do not intersect and are part of the universal set
I think it's commutative property of addition (you can change order of addition but in the end it would be the same)
Answer:
x = 65/16, y = 37/16
Step-by-step explanation:
solve the system algebraically
x+3y=11
4x-4y=7
Try substitution.
let x = 11 - 3y
Plug in.
4(11 - 3y) - 4y = 7
44 - 12y - 4y = 7
44 - 16y = 7
37 = 16y
y = 37/16
x = 11 - 3*y
x = 11 - 3*(37/16)
x = 11 - 111/16
x = 65/16
Consider, pls, this explanation + solution:
according to the given equation the centre of this circle is in the poit (6;7) and its radius =4 units.
Using this data, it is possible to define right choice: D.
answer: graph D.
Answer: Range is a set/group of y-value points of a function. If/when the dot is filled in, the number is included in the set. This is signified by a bracket []. If/when the dot is not filled in, the number is not included in the set. This is signified by a parentheses (). The range of this graph is [4,-9).
