Answer:
e): m=18.50d + 25
Step-by-step explanation:
5 + 6 − 1 2 − 1 1 -11y 5+6y−12−11y − 7 + 6 − 1 1
− 7 + 6 − 1 1 −7+6y−11y − 7 − 5
− 7 − 5 −7−5y − 5 − 7
Solution: −5y−7
Answer:
B. $1680
Step-by-step explanation:
Note the simple interest formula:
Interest = (Principal)(rate)(time)
Principal = $6000
Rate = 7% = 0.07
Time = 4
Plug in the corresponding numbers for the corresponding variables.
I = (P)(R)(T)
I = (6000)(0.07)(4)
Multiply.
I = (24000)(0.07)
I = 1680
Interest is $1680.

Put that in the calculator changing the + or - sign both times tp find x
Part A-For marigold plants X, a geometric sequence has a general form of:
X = Xo * (1 + r)^n
where r = -15% = -0.15 (negative since it is decreasing)
Xo = the initial amount of marigold plants = 150
X = 150 * (1 – 0.15)^n
X = 150 (0.85)^n
