Answer:
x = 11.75
Step-by-step explanation:
Answer:
ΔABC ~ ΔEDF; x = r × w/z
Step-by-step explanation:
m∠ABC = 180 -47 - 62 =71 = m∠EDF
ΔABC ~ ΔEDF
w/z = x/r
x = r × w/z
Answer:
y = -3/4x -5
Step-by-step explanation:
(4, -8) and (-8, 1)
m = (y2-y1)/(x2-x1)
m= (1+8)/(-8-4)
m = (9)/(-12)
m = -3/4
y - y1 = m(x-x1)
y + 8 = -3/4(x -4)
y + 8 = -3/4x + 3
y = -3/4x -5
Answer:
-35x³ - 39x² + 25x
Step-by-step explanation:
First write out the equation which is (5x - 3x²) - (5x - 2)(10x + 7x²). Then distribute 5x - 3x² to -(50x² + 35x³ - 20x - 14x²). After that, combine the like terms and don't forget to distribute the negative as well, 5x - 3x² - 36x² - 35x³ + 20x. Lastly combine all the like terms to end up with this -35x³ - 39x² + 25x.
Hope this helps :)
