Answer: You need a grade of 78 on the final exam to earn a final grade average of at least 87 in each grading system.
Step-by-step explanation:
(85 + 90 + 95 + x)÷ 4 =87
Simplify:
(270 + x) ÷ 4 = 87
Rearrange:
(x + 270) ÷ 4 = 87
Multiply terms to Reduce:
4((x + 270) ÷ 4) = 4 * 87
Cancel Multiplied terms in Denominator:
x + 270 = 4 * 87
Multiply:
x + 270 = 348
Subtract 270 on both sides of the equation:
x + 270 - 270 = 348 - 270
Simplify:
x = 78
Y = 20x + 7 for instance
then just substitute the values
Answer:
y > 0 best describes the range of the function f(x) = 2(3)x.
A function whose value is a constant raised to the power of the argument, especially the function where the constant is e.
If b is any number such that and then an exponential function is a function in the form, where b is called the base and x can be any real number.
