y=-2x+7
Step-by-step explanation:
line segment xy has endpoints x(5 7) and y(-3 3)
for the equation of the perpendicular bisector of line segment xy
slope of line segment xy = 7-3 / 5+3
= 4/8
=1/2
so slope of perpendicular bisector is -2
as m1m2= -1 or m1= -1/m2
As perpendicular bisector goes through midpoint of xy , let's find midpoint of xy
midpoint(x,y) = (5-3 / 2 , 7+3 / 2)
=(2/2, 10/2)
=(1,5)
find the equation of line(perpendicular bisector) passing through (1,5) and the slope -2
y-5 = -2(x-1)
y-5 =-2x+2
y=-2x+7
Answer: B
Step-by-step explanation:
Answer:
The expression Barak could use to find the amount he will spend to feed his pet lizards for one day = Number of pets × number of crickets per pet × cost of each crickets
Step-by-step explanation:
Pet lizards = 4
Each lizard eats 5 crickets
4 pet lizards will eat = 4 × 5 crickets
= 20 crickets
A cricket = 12 cents
That is, $0.12
Cost of 20 crickets = 20 × $0.12
= $2
The expression Barak could use to find the amount he will spend to feed his pet lizards for one day
= Number of pets × number of crickets per pet × cost of each crickets
= (4) (5) (0.12)
= $2.4
Answer:
8
Step-by-step explanation:
x(x+6)/2=56
x^2(6x)=112
x^2(6x)-112=0
By trial and error, we can try base =1, height = 7, etc
base =8
height = 14
