Answer:$5215.25
Step-by-step explanation:
Principal(p)=$2300
rate(r)=6.5%
time(n)=13years
amount =p(1+r/100)^n
Amount=2300 x (1+6.5/100)^13
Amount=2300x(1+0.065)^13
Amount=2300x(1.065)^13
Amount =2300 x 2.2675
Amount =5215.25
the given equation is -6x=9
here x=-9/6 = -1.5
x=-1.5
so the graph would be a line parallel to y axis passing through x=-1.5
two ordered pair can be : (-1.5,0) and (-1.5,2)
Graph is shown in attachment
Equation for Singer A: 55 + 20x
Equation for Singer B: 85 + 5x
Make the two equations equal to each other and solve for x.
55 + 20x = 85 + 5x
20x - 5x = 85 - 55
15x = 30
x = 30/15 = 2 hours.
Answer:
At 2 hours both singers will charge the same amount of price.
Answer Check:
Singer A Cost: 55 + 20 (2 hours) = $ 95
Singer B Cost: 85 + 5 (2 hours) = $ 95
