The average rate of change of a continuous function f(x) in an interval (a, b) is
(f(b) - f(a)) / (b - a)
So for
f(x) = 3x ² + 2x + 5
on the interval (0, 2), we have
• f (2) = 3 • 2² + 2 • 2 + 5 = 21
• f (0) = = 3 • 0² + 2 • 0 + 5 = 5
so that the average rate of change is
(f (2) - f (0)) / (2 - 0) = (21 - 5) / 2 = 16 / 2 = 8
and the answer is B.
Which equation represents a line parallel to
the line y = 3x - 2?
Answer:
y=3x+2
Step-by-step explanation:
-2's opposite is positive and the rate of change (slope) is constant

help me please !!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
I believe it would be 3n^2 (last option)
Step-by-step explanation:
By definition;
monomial- one term
coefficient- the number in front of a variable
(in this case, without the squared power, it would look something along the lines of "3n", where the 3 is the coefficient and the "n" is the variable.)
sooooooo,
even without the "2nd degree" we can just use the system of elimination and cross out the answers that don't consist of one number, and that don't have a coefficient of 3.
I hope this answer was helpful, please let me know if you got it correct. :)

You were paid $8 per hour to babysit last Saturday for 5 hours. You also mow lawns for $15 per lawn. You mowed 4 lawns this month. You spent a total of $5 in gas for the lawnmower this month. On your way home from babysitting, you spent $2.75 to buy yourself a snack. You want to buy a video game console that costs $100. Did you make enough this month to buy it?
Answer:
Step-by-step explanation:
8 times 5 is 40. 15 times 4 is 60. 40 plus 60 is 100. spending means you're giving money so subtract that from 100
100-5 is 95. 95-2.75 is 92.25
92.25<100. so no you didn't make enough

Vector u has initial point at (3, 9) and terminal point at (–7, 5). Vector v has initial point at (1, –4) and terminal point at (6, –1).
What is u + v in component form?
⟨-10, -4⟩
⟨-5, -1⟩
⟨3, 9⟩
⟨5, 3⟩
Answer:
⟨-5, -1⟩
This is the right answer Edge 2020
Step-by-step explanation:
U + v in the component form will be -5 [tex]\hat{i}[/tex] - [tex]\hat{j}[/tex] hence, ⟨-5, -1⟩ will be the correct answer.
What is a vector?An item with both magnitude and direction is referred to be a vector.
A vector can be visualized geometrically as a straight spline, with a pointing in the orientation and a length equal to the value of the vector.
Geometrical objects with magnitude and direction are called vectors.
A line with an arrow in its direction can also be used to represent a vector, and the length of the line relates to the vector's amplitude.
Given that a vector initial point at (3, 9) and terminal point at (–7, 5). Vector v has initial point at (1, –4) and a terminal point at (6, –1).
So vector A = -10[tex]\hat{i}\\[/tex] - 4[tex]\hat{j}[/tex] and B = 5[tex]\hat{i}\\[/tex] +3[tex]\hat{j}[/tex] now vector joning by this two will be AB = -5 [tex]\hat{i}[/tex] - [tex]\hat{j}[/tex] .

1. Solve for x. 5% + 15 = 28 (5 points)
Answer:x=2.6
Step-by-step explanation:
Simplifying (5x + 15) = 28 Reorder the terms: (15 + 5x) = 28 Remove parenthesis around (15 + 5x) 15 + 5x = 28 Solving 15 + 5x = 28 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-15' to each side of the equation. 15 + -15 + 5x = 28 + -15 Combine like terms: 15 + -15 = 0 0 + 5x = 28 + -15 5x = 28 + -15 Combine like terms: 28 + -15 = 13 5x = 13 Divide each side by '5'. x = 2.6 Simplifying x = 2.6

Answer:
0 = − 6
Step-by-step explanation:
Subtract 7 from both sides of the equation
3 + 7 =3 + 1
3 + 7 =7 = 3 + 1− 7
Simplify
3 = 3 -6
Subtract 3 from both sides of the equation
3 = 3 − 6
3 − 3 = 3 − 6 -3
Simplify
