Answer:
B
Step-by-step explanation:
y=mx+b
y=-x (y=-1x+0)
b=0
m=rise/run=-1/1
Sample Response: Yes, the product can be rational. The best example for this to happen is if you take the square root of a non-perfect square and square it, or multiply it by itself. This “undoes” the squaring, so you get a whole number, e.g. √5x√5 = 5.
Step-by-step explanation:
AC = 20
AB = 18
BC² = 20²+ 18² -2•20•18•cos(52°)
BC² = 280.72
BC = √280.72
BC ≈ 16.75
Angle C:
18² = 20² + 16.75² -2•20•16.75•cos(C)
324 = 400 + 280.72 -670•cos(C)
cos(C) = -356.72/-670
cos(C) ≈ 0.53
acos(0.53) = C
C = 57.8°
Angle B:
180-52-57.8 = 70.2°
Answer:
either y = x or x = 1
Step-by-step explanation:
i dunno for sure but i think its y = x
73.94 X .33 = 24.40 thats how much the markup (or profit is)
73.94 + 24.40 = 98.34 thats how much they sold it for.
