Answer:
y=-12x-9
Step-by-step explanation:
plug the value of m and b in the equation:
-y=12x+9
divide negative 1
y=-12x-9
5 tickets for $30
this means one ticket is $6 as 30÷5=6
7 multiplied by 6= $42
7 tickets would cost $42
Answer:
time period (t) is 2.25 years
Step-by-step explanation:
Given data in question
amount (a) = $94000
principal (p) = $78870
rate (r) = 7.8 % = 0.078
to find out
time period (t)
solution
we know that continuous compound interest formula i.e.
amount = principal 
...............1
we will put all value a, p and r in equation 1
amount = principal
94000 = 78870 
= 94000 / 78870
now we take ln both side
ln ln (94000 / 78870)
0.078 t = ln 1.19183466
0.078 t = 0.175494
t = 0.175494 /0.078
t = 2.249923
so time period (t) is 2.25 years
Answer:
Step-by-step explanation:
#6
a n
---- = ---- Solve for a. Note that if we multiply both sides of this equation by
m p n
m, we get a = m * ----
p
m*n
and this simplifies to a = mn/p or a = ---------
#7 Solve mx = np for x. We want to isolate x on the left side. Dividing
both sides by m isolates x on the left and adds the divisor m on the right:
np
mx = np => x = ------
m
#8 Solve c - x = d + r for x We want -x alone on the left side. Accomplish this by subtracting c from both sides, obtaining:
-x = d + r - c. Now multiply both sides by -1, obtaining x = -d - r + c
