The equation for a line that passes through the point of (3, 9) and has a slope of 2 in slope intercept form is y=2x+3
Answer:
1+3i
Step-by-step explanation:
i is a variable. -1 has an absolute value of 1. 3i is multiplying i by 3.
There was $800 deposited at 9% interest and $400 deposited at 4% interest.
The formula for simple interest is I = prt. Using our information we have:
88 = x(0.09)(1) + (1200-x)(0.04)(1)
88 = 0.09x + 48 - 0.04x
88 = 0.05x + 48
Subtract 48 from both sides:
88 - 48 = 0.05x + 48 - 48
40 = 0.05x
Divide both sides by 0.05:
40/0.05 = 0.05x/0.05
x = 800
1200 - x = 400
96 messages .... $4.80
