M∠BDC=half the arc it faces=1/2 of 54=27
BD is the diameter, so m∠C=90
m∠DBC=180-90-27=63
Answer:
Step-by-step explanation:
-2 + 2(3) =-2 +6 = 4 for the 2nd equation
2(-2) + 4(3) = -4 +12 = 8 for the 2nd equation
(-2,3) satisfies both equations
let x = 0, then y= 2 (0,2) is another solution
there's multiple solutions, including (-2,3) and (0,2). That eliminates all answers except the first
Try graphing the two equations. They're the same line, with an infinite number of points on the line, which means an infinite number of solutions.
Answer: i need time to work on this but i think its 3,3
Step-by-step explanation:
The ones that simplify to x=x or c=c where c is a constant
as soon as you have
ax+b=c where a, b, and c are constants (and b≠0 and a≠0), then there is one solution
A. -4.4+3y=4.3-3y
-4.4+6y=4.3
this has one solution
B. -1/3y+2.5=1.2
this has 1 solution
C.
6.3+2y=6.3+2y
2y=2y
y=y
infinite solutions
D. 4/10y=2.3+15/10y
-11/10y=2.3
1 solution
C is the answer
