Answer:
C(p) = p*50 + 300
Step-by-step explanation:
Using the names:
Clm: cost of labor and materials
Crm: fixed cost on rent and equipment
p: number of phones
and Ct: total cost
the ecuation would be number of phones times the cost and material plus the fixed cost, something like this
p * Clm + Crm = Ct
on the example we have all the data except the rent and equipment cost (the fixed cost) so thats what we need to solve
producing 3 phones its
3 *¨50 + Crm = 450
Crm = 450 - 150 = 300
so replacing in the above formula the equation would be
C(p)=p * 50 + 300
Answer:
x=-3
Y=-5
Step-by-step explanation:
2x-y=-1 ×2
3x-2y=1. ×1
4x-2y= -2
3x-2y=1
eliminate y by subtracting
Answer:
Given: BD is an altitude of △ABC .
Prove: sinA/a=sinC/c
Triangle ABC with an altitude BD where D is on side AC. Side AC is also labeled as small b. Side AB is also labeled as small c. Side BC is also labeled as small a. Altitude BD is labeled as small h.
Statement Reason
BD is an altitude of △ABC .
Given △ABD and △CBD are right triangles. (Definition of right triangle)
sinA=h/c and sinC=h/a
Cross multiplying, we have
csinA=h and asinC=h
(If a=b and a=c, then b=c)
csinA=asinC
csinA/ac=asinC/ac (Division Property of Equality)
sinA/a=sinC/c
This rule is known as the Sine Rule.

Step-by-step explanation:
Answer:
#2, AB is congruent to AD
Step-by-step explanation:
AB is congruent to AD.
since the bottom sides are corresponding, and the middle sides are corresponding, then if the outside sides are corresponding, then CAB is congruent to CAD
