Answer:
The unit cost of one toy reindeer is $3 and the unit cost of one box of cookies is $2
Step-by-step explanation:
Let
x ----> the unit cost of one toy reindeer
y ----> the unit cost of one box of cookies
we know that
----> equation A
----> equation B
Solve the system by graphing
The solution is the intersection point both graphs
using a graphing tool
The solution is the point (3,2)
see the attached figure
therefore
The unit cost of one toy reindeer is $3 and the unit cost of one box of cookies is $2
Answer:
2 : 3
Step-by-step explanation:
Given ratio of sides of 2 similar triangles = a : b , then
ratio of areas = a² : b²
Here by working in reverse
ratio of areas = 4 : 9 , thus
ratio of sides = 
: 
= 2 : 3
Answer:
y = x for x ≥ 0 and y = - x for x < 0
Step-by-step explanation:
The absolute value function is written as y = |x| and it is defined as following
|x| = x when, x ≥ 0 and |x| = - x when, x < 0.
Therefore, the equations for the domain of x ≥ 0 is y = x
and the equation for the domain of x < 0 is y = - x (Answer)
Answer:
21
Explanation:
d=m/v
3=m/7
Multiply both sides by 7 to cancel it out of the right side
3*7=(m/7)7
21=m
