7/8 would be the answer is the most simply form available
<span>2/5(10x - 10y) - 3/4(12x - 24y)
=4x - 4y - 9x + 18y
= -5x + 14y
answer is </span><span>A) -5x + 14y </span>
Using the y=mx+b format,
m the slope = (5--9)/(8--12) = 14/20 = 7/10=0.7
y-y1 = m(x-x1)
y-5 = .7(x-8) = .7x-5.6
y = .7x +0.6
10y = 7x + 6
so 7x - 1y = -6 any your equation is almost correct.
Answer:
x = 95°
y = 147°
z = 128°
Step-by-step explanation:
z = 180 - 52 = 128°
x: first find the remaining angle in the big triangle, 180 - (45 + 50) = 85°
x = 180 - 85 = 95°
y: first find the remaining angle in the small triangle, 180 - (95 + 52) = 33°
y = 180 - 33 = 147°
all real numbers are greater than or equal to the equation
