C. 3x^2+6 is the answer:)
Positive 2 is your slope, (rise over run) if you have to graph it and -1 is your y-intercept
1) split the range in three identical invervals of size [6 - 0] / 3 = 2
2) form three rectangles
2a) First rectangle: base 2, height f(2) = 2^2 + 1 = 5
area 1 = base * height = 2 * 5 = 10
2b) second rectangle: base 2, height f(2+2) = 4^2 + 1 = 17
area 2 = 2 * 17 = 34
2c) third rectangle: base 2 height f(4+2) = 6^2 + 1 = 37
area 3 = 2*37 = 74
3) total area = area 1 + area 2 + area 3 = 10 + 34 + 74 = 118
Answer:
a = 19
Step-by-step explanation:
Given the equation of:
First, multiply both sides by 3. That will clear the denominator which makes it easier to solve for a variable:
Subtract both sides by 5 to isolate the variable:
Therefore, the value of a is 19.
