Find f(g(x)) and g(f(x)).
Given: f(x)= 3x – 1; g(x) = 7x + 6
Answers
Answer:
When f(x)= 3x – 1 and g(x) = 7x + 6,
f(g(x)) = 21x + 17
and
g(f(x)) = 21x - 1
Step-by-step explanation:
Given:
f(x) = 3x - 1
g(x) = 7x + 6
To find f(g(x)), substitute the value of g(x) into f(x).
f(g(x)) = f(7x + 6)
Substitute variable.
f(7x + 6) = 3(7x + 6) - 1
Distribute the 3 inside the parenthesis.
f(7x + 6) = 21x + 18 - 1
Subtract 1 from 18.
f(7x + 6) = 21x + 17
Therefore, f(g(x)) is 21x + 17.
To find g(f(x)), substitute the value of f(x) into g(x).
g(f(x)) = g(3x - 1)
Substitute variable.
g(3x - 1) = 7(3x - 1) + 6
Distribute the 7 inside the parenthesis.
g(3x - 1) = 21x - 7 + 6
Add 6 to -7.
g(3x - 1) = 21x - 1
Therefore, g(f(x)) is 21x - 1.
Which fraction is equal to 0.54--
Answers
Answer:
27/50
Step-by-step explanation:
Answer:
27/50
Step-by-step explanation:
54 is another way of writing 54 hundredths, or as a fraction, 54/100. Asking for a simplified fraction is asking you to reduce the numerator and denominator by any common terms. 54 and 100 are both divisible by 2, so we get to 27/50. These have no factors in common, so 27/50 is our simplified fraction.
Suppose that two asteroids in the asteroid belt are moving in a straight line and at the same speed toward each other. If a 3D coordinate system is placed with the origin at the sun, then the position of one asteroid can be described as 2.8 astronomical units (AU) in the direction of positive x, 0.3 AU in the direction of positive y, and 0.15 AU in the direction of positive z. At the same time, the position of the other asteroid can be described as 2.7 AU in the direction of positive x, 0.23 AU in the direction of positive y, and 0.12 AU in the direction of positive z. At what point in this 3D coordinate system will they collide? Use the midpoint formula

Hence Proved !Shandra scored 75 on her first math test. She scored
20% higher on her next math test. What did she score
on her second test?
Answers
Answer:
90
Step-by-step explanation:
20% of 75 is 7.5 times 2 which equals 15 so 15 plus 75 is 90.
Answer:
She scored 90 on her second math test.
Step-by-step explanation:
A 20% increase is 120% of the original number. 120% is also just a multiplier of 1.2. Multiply the first score by 1.2 to get the second score:

Answers
Answer:
You can pay a maximum of $84.
formula is:
84 = 40 + .22*m
subtract 40 from both sides of this equation to get:
44 = .22*m
divide both sides of this equation by .22 to get:
44/.22 = m
simplify to get:
m = 200

the measure of an angle is nineteen times the measure of its complementary angle. what is the measure of each angle?
Answers
Step-by-step explanation:
officially, complementary angles complete each other to a total sum of 90 degrees.
supplementary angles complete each other to a total sum of 180 degrees.
angle 1 = 19× angle 2
90 = angle 1 + angle 2 = 19×angle 2 + angle 2 = 20×angle 2
angle 2 = 90/20 = 9/2 = 4.5 degrees.
angle 1 = 19×4.5 = 85.5 degrees.
and so, it seems to me, your teachers made a severe definition mistake and aimed for 180 degrees instead of the correct 90 degrees.
in that case, everything doubles.
angle 2 = 9 degrees
angle 1 = 171 degrees
If measure of an angle is 19-times measure of its complementary-angle, then measure of one angle is 85.5° and other is 4.5°.
Let us denote the measure of the angle as = "x" degrees.
The complementary angle is the angle that, when added to the given angle, forms a 90-degree angle.
The complementary-angle to "x" degrees is = (90 - x) degrees,
We know that the measure of the angle is nineteen times the measure of its complementary angle, we can write the equation as :
x = 19(90 - x),
x = 1710 - 19x,
20x = 1710,
x = 1710/20,
x = 85.5,
Therefore, the measure of the angle is 85.5 degrees. The measure of its complementary angle is 90 - 85.5 = 4.5 degrees.

Graph the line with slope 2 passing through the point (-1, -3).
Answers
Answer:
Step-by-step explanation:
Start with the standard equation of a straight line, y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).
We know m, so:
y = 2x + b
Now find b by using the given point (-1,-3)
y = 2x + b
-3 = 2(-1) + b
b = -1
The equation is y=2x-1

Step-by-step explanation:
The volume of a cone can be represented by:
V = (π)(r²)(h/3)
Substitute the known values:
π = 3.14
r = 12
h = 9
V = (3.14)(12²)(9/3)
Square 12.
V = (3.14)(144)(9/3)
Divide 9 by 3.
V = (3.14)(144)(3)
Multiply 3.14 and 144.
V = (452.16)(3)
Multiply 452.16 and 3.
V = 1356.48
Round to the nearest tenth.
V = 1356.5.
