Answer:
H) -5x - 50
Step-by-step explanation:
(-5 · x) + (-5 · 10) = -5x - 50
Step-by-step explanation:
A quadratic graph will surely help you find the solutions
X2-x-2=0
x1=2 x2= -1
Substitute each of the x value in the original equation to get the y value
(2)^2-(2)-2= 0 (2,0)
(-1)^2-(-1)-2=-2 (-1,-2)
plot the coordinates on the graph,the graph should be a curve
Answer:
-1/5
Step-by-step explanation:
It has a rise of 2 and a run of -10, therefore it is a slope of -2/10 or -1/5
3y=−4x+2
y = -4x/3 + 2/3
y = 3x/4 + 2/3
so the slope is 3/4 remember that perpendicular slope is just the opposite reciprocal of the original slope given.
Vbox-vspheres
vbox=, I assume we are dealing with l=w=h
so
v=lwh=12^3=1728
vsphere=(4/3)pir^3
r=3
vsphere=(4/3)pi3^3=4pi9=36pi
8 of them so
8 times 36pi=288pi or about 904.7786842338604526772412943845 cubic inches
vbox-sphere=1728-904.7786842338604526772412943845=823.2213157661395473227587056155
space filled by packing beads is about 823.22 cubic inches
beads percent is 823.2213157661395473227587056155/1728 times 100=47.64% filled by beads
