Answer:
M=p-5n
Step-by-step explanation:
Here we are given that M+5n=p
We are asked to solve this equation for M. In order to do that we will follow these steps.
Subtracting 5n from both sides we get
M+5n-5n=p-5n
M=p-5n
Hence , now we have our M as dependent variable, whose value depends on the values of p and n. One or both of them can be independent variable/.
Answer:
minutes at daytime rate: 3.00
minutes at nighttime rate: $2.70
total cost of call: $8.55
Step-by-step explanation:
split up the hours so you have the 5 cent charge per minute for 1 hour and you have the 3 cents a minute for an hour and a half after 8.
multiply 5 cents a minute by 60 to get the amount of money for the first hour($3.00),
next multiply 3cents a minute by an hour and a half (90 minutes) to get $2.70
next add the money together to get $5.70 and multiply that by 1.5 to get $8.55
Answer:
-1/ 4
Step-by-step explanation:
y = 4x-3 has a slope of 4 because the equation is in slope intercept form
y = mx+b where the slope is m
Perpendicular lines have slopes that are negative reciprocals
-1/ 4 is the slope of a line that is perpendicular to y = 4x-3

Answer:
c = 34
Step-by-step explanation:
x²+19x+c=0
(x + a) (x + b) = x² + (a + b) x + ab
a + b = 19
a - b = 15
a = 17
b = 2
c = ab = 34
