Answer:
(x,y)=(-13,-12)
Step-by-step explanation:
5x - 7y = 19
7x - 7y = -7 Multiply both sides of the equation by -1
Which then gives you :
5x-7y=19 Sum the equations vertically to eliminate
-7x+7y=7 at least on variable
-2x=26 Divide both sides of the equation by -2
X=-13 Substitute the given value of x into the equation 7x - 7y =-7
7 x(-13)-7y=-7 solve the equation for y
y=-12
Thus gives you (-13,-12)
Hope this was useful!!! Sorry if it's wrong.
If two angles are complementary, the sum of their measures is 90 degrees. Call one of the angles x. This means that its complement is 90 - x degrees. But the difference in their measures is 12 degrees.
Answer:
D
Step-by-step explanation:
In Maths, axioms are basically set of propositions from which we can derive true statements from logic. Then these statements are known as theorems.
Hence, defining theorem in an axiomatic way means that a statements that we derive from axioms (propositions) using logic and that is proven to be true.
From the answer choices, we see D goes with this, hence D is the correct answer.

Simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers.
Answer:
6x-11
Step-by-step explanation:
so g(f(x)) means wherever in g(x), you see x, you replace it with f(x)
g(x) = 3x+1
g(f(x)) = 3(2x-4)+1
= 6x-12+1
= 6x-11
