Step-by-step explanation:
Equation of straight line is y=mx+c
choose any two points on straight line
for me I choose:(-3,11) and (3,-1)
use these two points to find gradient,m.
m= (-1-11)/(3-(-3))
m= -2
now, y=-2x+c
choose any point on the straight line
I choose point (3,-1)
sub the point into the equation to find c
-1=-2(3)+c
c=5
equation: y=-2x+5
Answer:
y intercept is 4
Step-by-step explanation:
Answer: Population = 1.380
Step-by-step explanation:
Step 1 :
Population density is defined as the measure of average the population of people per unit of area( per square mile). And is calculated as
Population density =
Number of People / Land Area in Square Km.
Step 2
given Population density = 60 people per square kilomete
Land Area= 23 square kilometer
Population =Population density x Land Area in Square Km
= 60 people per square kilometer x 23 square kilometer
=1,380.
Answer:
mAC=70°
Step-by-step explanation:
Someone can corroborate this but:
180°-110=70°=(m<aed)
180°-(m<aed)=70°
mAC=mBD
