Answer: count units between zeros
Explanation:
meaning, say one x1 = (-4,0) and x2 = (3,0) count from -4 all the way to 3 and see how many units it took (7units) thats how u find the distnace between the x intercepts
y=x2+x-2
x+y=1
If(x,y)is a solution of the system of equtions abpve which of the following is possible value of xy?
Answer:
The equations are :
y=x²+x-2
x+y=1⇒ y= 1-x
multiply(y=1-x) by -1 then add it to y= x²+x-2
you get : x²+x-2+x-1=0⇒ x²+2x-3 = 0
let Δ be the dicriminat of this equation :
a= 1b= 2c= -3Δ = 2²-4*1*(-3)= 16
so this equation has two solutions
x= (-2-4)/2 = -3 or x=(-2+4)/2 = 1
then :
if x= -3 y= 4 y= 1+3 if x = 1 y= 0now the possible solutions are (-3,4) and (1,0)
the possible values of xy are :
-12 : -3*4= -120 : -3*0= 0 4 : 4*1= 4 0 : 1*0=0so xy could be : 0 or 4 or -12
A 10 kg ball is traveling at the same speed as a 1 kg ball. Compared to the 10 kg ball, the 1 kg ball has A) the same momentum B) 1/100 the momentum C) ten times the momentum D) 1/10 the momentum
Answer:
I think it is D

Smaller particles moved by the wind occurs through deflation.
Answer:
True
Explanation:
Deflation is a geological process, in which the erosion of the loose surface materials or small particles occurs because of the physical action of high speed wind current. It generally occur in the flat and dry areas, uncemented sediments, deserts, floodplains, dry lake bottom, and glacial plains which are out washed.

true
