Answer:
12 and 9
Step-by-step explanation:
x=larger number y=smaller number
x+y=21
x=2y-6 (system of equations)
x=21-y
2y-6=21-y
3y=27
y=9
x+9=21
x=12
Answer:
Echo can plant a maximum of 8 shrubs.
The total cost for Echo's shrubs is = 8 $15.32 = $122.56
Step-by-step explanation:
i) Garden is 36 feet wide
ii) Each shrub is 4.5 feet wide.
iii) therefore the maximum number of shrubs that can be planted are
Therefore Echo can plant a maximum of 8 shrubs.
Therefore the total cost for Echo's shrubs is = 8 $15.32 = $122.56

Answer:
x^2/1024 -y^2/7744 = 1
Step-by-step explanation:
The parent hyperbola relation is ...
x^2 -y^2 = 1
This has asymptotes of y = ±x and x-intercepts of ±1.
For the given hyperbola, we want to scale x by a factor of 32, and y by a factor that is 2.75 times that, or 88. Then the equation could be written as ...
(x/32)^2 -(y/88)^2 = 1
More conventionally, the denominator is shown at full value:
x^2/1024 -y^2/7744 = 1
