It looks like they're multiplied, then you can simply add the exponents,
b⁸ * b⁴ = b⁸⁺⁴ = b¹²
remember, b⁸=b*b*b*b*b*b*b*b and b⁴=b*b*b*b
so b⁸ * b⁴ = b*b*b*b*b*b*b*b * b*b*b*b = b¹²
Answer:
11, 7, 3, -1, -5
Step-by-step explanation:
The dependent variable y is often used interchangeably with the function value f(x). That is, we can usually presume that ...
y = f(x)
__
<h3>evaluate the function</h3>
To find f(x), put the value of x everywhere x appears in the function definition, and do the arithmetic. A calculator or spreadsheet can relieve some of the boredom of repetition. Here are a couple of examples.
f(-2) = -4(-2) +3 = 8 +3 = 11
f(-1) = -4(-1) +3 = 4 +3 = 7
<h3>time saver</h3>
You may notice that each increase of 1 in the value of x causes a decrease of 4 in the value of y. That means we can simply subtract 4 from the previous value of y to find the next one:

Attached is an example of this table being filled by a calculator.
Answer:
C
Step-by-step explanation:
in this form y=mx+b the m is the slope of the line and b is the y intercept. here the line intercepts the y axis at -4. the slope is rise over run or more formally found by (y2-y1)/(x2-x1) and here it is -4/3

True
