Answer:
Negative
Step-by-step explanation:
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:
y=3x+5
y=-2x-1
y=-4x
y=1/2x+2
Step-by-step explanation:
These are linear functions(y=mx+b). m stands for the slope and b stands for the y intercept. After plugging in your slope, you use the coordinates they give you to find the y intercept. To find the y intercept plug in the y coordinate into the y in y=mx+b, and plug in the x coordinate into the same equation.

Hope my explanation made sense! I suck at explaining things lol.
Answer:
90 + 29 + x = 180
119 + x = 180
-119 -119
X = 61 degrees
A triangle will always equal 180 degrees.
Given that there is a right triangle it is 90 degrees, also given that 29 degrees is there we add those and add x (the unknown degree) to equal 180 degrees.
Answer:
Step-by-step explanation:
1) 20 for $1.56
The unit price is
1.56/20 = $0.078
= 7.8 cents each
2) $3.78 for 6
The unit price is
3.78/6 = 0.63
= 63 cents each
3) 2 1/2 for 1 dollars
The unit price is
1/2.5 = 0.4
= 40 cents each
4) 5 at 3.9
The unit price is
3.9/5 = 0.78
= 78 cent each
5) 1 1/2 for 1.58
The unit price is
1.58/1.5 = 1.05
= 1.05 each
