The rules of exponents tell you to add exponents in the numerator and subtract those in the denominator. A power of a power causes the exponent to be multiplied.
Answer:
they are congruent so 47 is also the measurement for its corresponding angle(aka the corner that doesn't have a variable)
and in a triangle, interior angles add to 180 so 47+x+y=180
90 + 43 = 133
+47= 180
so your answer is a
hope this helps!!
Answer:
x=0, y=-5
Step-by-step explanation:
The system is
(1) 5x+3y=-15
(2) -8x-2y=10
Let's solve it by elimination. In order to do it, you have to multiply the equations by suitable numbers in such a way that when you add the 2 equations, one of the unknowns is eliminated
Multiply (1) by 2 and (2) by 3
(1) 10x+6y=-30
(2) -24x-6y=30
Add the two equations
10x-24x+6y-6y=-30+30 ----> -14x=0---->x=0
Now replace this value in any equation, for example in (1)
6y=-30 ----> y=-30/6----> y=-5
Answer:
a
Step-by-step explanation:
the transversal across two parallel lines causes the consecutive internal angles to be congruent according to the consecutive internal angles theorem.
