Answer:
Step-by-step explanation:
Divide 3 on both sides of the equation.
Answer:
Step-by-step explanation:
"Find the values of x that satisfy 3x - 2x^2 = 7." Please do not use " × " to represent a variable; " × " is an operator, the "multiply" operator.
Rearrange these three terms in descending order by powers of x:
-2x^2 + 3x - 7 = 0. Here the coefficients are a = -2, b = 3 and c = -7, and so the discriminant of this quadratic is b^2-4ac, or 9 - 4(-2)(-7), or 9 - 56, or -47.
Because the discriminant is negative, we'll have two different complex roots here. The quadratic formula becomes
-3 ± i√47 -3 ± i√47
x = ----------------- = -------------------
2(-2) -4

A term is a expression.
Answer: 5.6%
Step-by-step explanation:
Formula for simple interest: Interest = 
, where P= Principal , R = Rate of interest , T= Time.
Given: P= $3,875, T= 3 years , Interest = $651
Substitute all values in formula, we get
Hence, the required rate = 5.6%
