Answer:
y=3x+5
Since it's already 5 cm we have +5
every month it would go up by 3 cm so we have 3 and x is to represent the # of months.
Solve for y in the first equation.
Answer:
25763253685.3
Step-by-step explanation:
Answer:x=-5 and x=3
Step-by-step explanation:
log(x^2-15)=log(2x)
Cancel log at both sides we get
x^2-15=2x
Collect like terms
x^2-2x-15=0
x^2-3x+5x-15=0
x(x-3)+5(x-3)=0
(x+5)(x-3)=0
x+5=0 x-3=0
x=-5 x=3
First you need to convert them to the same unit. 1 cm is 10 mm, so the scale is 5:10. 5*2 is 10, so the scale factor is 2.
