Answer:
-8 + i
Step-by-step explanation:
(-3 + 2i) * (2 + i)
= -6 + -3i + 4i + 2i^2
= -6 + i - 2
= -8 + i
Answer:
2 - 2y^2 - x/y
Step-by-step explanation:
2x^2/x^2 = 2
and
x^2/xy = x/y
therefore
2x^2/x^2 - y^2 - x^2/xy - y^2
= 2 - y^2 - x/y - y^2
= 2 - y^2 - y^2 - x/y
= 2 - 2y^2 - x/y
The slope or increase in cost per pound is 3. (1 pound of grapes costs $3).
Answer:
38, 1
Step-by-step explanation:
Since this is a transversal, we know that 3x + 2x -10 is equal to 180. Therefore:
3x + 2x - 10 = 180
5x - 10 = 180
5x = 190
x = 38
We know that 12x + 8 is equal to 4x + 16 because they are corresponding angles. So:
12x + 8 = 4x + 16 (subtract 4x, and subtract 8)
8x = 8
x = 1
Answer:
y=-2x + 5
Step-by-step explanation:
y=mx+b
m=slope
b= y intercept
since on the y line the line intercepts on 5 you replace 5 with the b.
As for the m(slope) when the line is decreasing (going down) its automatically a negative number. and since (0,5) (1,3) 5-3=2 -2 would be ur slope.
