Find the equation of the first line using the two given points: (1,-1) (-1,-5)
Slope = change in Y over change in x:
Slope = (-5-(-1)) / (-1-(1) = -4/-2 = 2
Now find y intercept: y - y1 = m(x-x1) = y -(-1) = 2(x-1)
Simplify to get y = 2x-3
Now a perpendicular line has a opposite reciprocal slope.
The perpendicular line would be y = -1/2x - 3
You are told the y intercept is -4 units greater, so add -4 to -3 to get -7
The answer would be A. y = -1/2x-7
Answer: 82 ft squared
Step-by-step explanation: The surface area is 2( wl + hl + hw)
so the width is 2 the length is 7 and the height is 3
so it's 2( 14 + 21 + 6) = 2(41) = 82
3,500,000 - 2,800,000 = 700,000
So the magazine needs 700,000 readers to meet their goal.
Hope that helps you. :-)
Answer:
8308?
Step-by-step explanation:
Answer: x = 24º
Step-by-step explanation:
180 - 94 - 41 = 45
x + 111 + 45 = 180
x + 156 = 180
x = 24
