f(x) = x+4
g(x) = 3x2 - 7
Find (f•g)(x)
Answer:
3x³ + 12x² - 7x - 28
Step-by-step explanation:
(f • g)(x) = f(x) × g(x)
= (x + 4)(3x² - 7)
Each term in the second factor is multiplied by each term in the first factor, that is
x(3x² - 7) + 4(3x² - 7 ) ← distribute both parenthesis
= 3x³ - 7x + 12x² - 28
= 3x³ + 12x² - 7x - 28
Find X

Which table represents a linear function?
At a glance, Kendra believes that the function represented on the graph is linear.
How can Kendra determine if the function is actually linear?
She can check to see if the rate of vertical increase equals the rate of horizontal increase between each pair of points.
She can check to see if the sum of each y-value and x-value in every ordered pair is the same.
She can check to see if the quotient of each y-value and x-value in every ordered pair is the same.
She can check to see if the rate of change between the first two ordered pairs is the same as the rate of change between the first and last ordered pairs.

Answer:
y = 7
Step-by-step explanation:
Mathematically, according to the Pythagoras’ theorem;
The square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the two other sides
The hypotenuse is the side that faces the right angle and it is represented by the square root of 85 here
Thus, we have it that;
(√85 )^2= 6^2 + y^2
85 = 36 + y^2
y^2 = 85-36
y^2 = 49
y = √49
y = 7

Find the inequality represented by the graph
Answer:
y > -2/3 x + 3
Step-by-step explanation:
First we find the equation of the dashed line.
y = mx + b
We see b = 3.
The slope is -2/3.
The equation of the line is
y = -2/3 x + 3
The line is dashed, not solid, and the shading is above the line, so the inequality is
y > -2/3 x + 3

A Rectangular has area 12a^2 and perimeter 14a what are the dimensions of this Rectangular?
9514 1404 393
Answer:
3a by 4a
Step-by-step explanation:
For dimensions L and W, the area and perimeter are ...
A = LW = 12a^2
P = 2(L+W) = 14a
Using the second equation, we can find L:
L +W = 7a . . . . . divide by 2
L = 7a -W
Substituting into the area formula gives the quadratic ...
(7a -W)(W) = 12a^2
W^2 -7aW +12a^2 = 0 . . . . arrange in standard form
(W -3a)(W -4a) = 0 . . . . . . . factor (find factors of 12 that total 7)
Then we have the two solutions ...
W = 3a, L = 4a
W = 4a, L = 3a
The rectangle dimensions are 3a by 4a.

How are the steps for graphing a line
using slope-intercept similar to using
point-slope? How are they different?
Answer:
they both use y^2-y^1 and x^2 - x^1, one is to find the slope the other is to find the y intercept
Step-by-step explanation:
Slope-intercept is when you have a graph and a equation such as y=mx+b
y = y coordinate
m = slope
x = x coordinate
b = y intercept
point-Slope is when you have this equation and you use (x1, y1) as the coordinates to graph.
y - y1 = m * (x - x1)

29. The circumference of a circle is C centimeters. The diameter of the circle is 13
centimeters.
Which expression best represents the value of ar?
Answer:If the diameter is 13 you should try each answer until you find pi.
To find pi you have to divide the circumference by the radius.
You don't need to find the circumference in this question but you can.
The circumference is 40.82
Then you have to divide
40.82÷13
that equals 3.14
and because that is pi, C is your answer
Step-by-step explanation:
