If f(x) = 3x+ 2 and g(x) = 2x-2, what is (f-8)(x)?
Answer: x + 4
Step-by-step explanation:
If it is asking us for (f - g)x, then we will subtract the function g from function f. Why? The x distributes creating f(x) - g(x), so we use this to solve.
Given:
g(x) = 2x - 2
f(x) = 3x + 2
Set up:
f(x) - g(x)
(3x + 2) - (2x - 2)
Distribute the negatie:
3x + 2 - 2x + 2
Reorder to combine like terms:
3x - 2x + 2 + 2
Combine like terms:
x + 4
(f - g)(x) = x + 4
5. A moving car has kinetic energy. If the mass is doubled what happens to the
amount of kinetic energy? If the speed is doubled what happens to the amount
of kinetic energy?
Answer:
See below ~
Step-by-step explanation:
Change in KE if mass is doubled
KE (original) = 1/2mv²KE (new) = 1/2 x (2m) x v²KE (new) = mv²⇒ KE is doubledChange in KE if speed is doubled
KE (new) = 1/2 x m x (2v)²KE (new) = 1/2 x 4 x mv²KE (new) = 2mv²⇒ KE is quadrupledhow many inches are in 1 1/2 ?

Step-by-step explanation:
The relations between angles and arcs in this problem set are ...
The sum of central angles in a circle is 360°The measure of an arc is the measure of the central angle it subtendsThe measure of an inscribed angle is half the measure of the arc it subtends__
B.3.no identifier is given
4.Arc DBC is the difference between a full circle (360°) and short arc DC. The measure of short arc DC is marked as 96°, so ...
arc DBC = 360° -96° = 264°
5.Αrc BC is twice the measure of the inscribed angle BDC it subtends.
arc BC = 2×60° = 120°
6.Arc AB is the difference between 360° and the sum of arcs AD, DC, and CB.
arc AB = 360° -(90° +96° +120°) = 54°
7.Angle ACD is half the measure of arc AD.
Angle ACD = 90°/2 = 45°
8.Angle ADC is half the measure of arc AC, which is the sum of arcs AB and BC
angle ADC = (54° +120°)/2 = 87°
9.Angle ACB is half the measure of arc AB
angle ACB = 54°/2 = 27°
__
C.9.x° is the arc whose central angle is 200°
x° = 200°
y° is half the measure of x°
y° = 200°/2 = 100°
10.The relations between arcs and inscribed angles mean that opposite angles in an inscribed quadrilateral are supplementary.
x° = 180° -112° = 68°
y° = 180° -81° = 99°

Melody need 155 bags of 140 cu. inches to fill the vegetable garden.
What is Volume of Cuboid?The volume of the cuboid is the measure of the space occupied within a cuboid. The cuboid is a three-dimensional shape that has length, breadth, and height.
Here, Length of vegetable garden = 48 inch
breadth of garden = 30 inches
height of garden = 15 inches
Volume of garden = Length X width X height
= 48 X 30 X 15
= 21600 cu. inches
Volume of each bag = 140 cu. inches
Number of Bags required = Volume of garden/Volume of each bag
= 21600 / 140
≈ 155
Thus, Melody need 155 bags of 140 cu. inches to fill the vegetable garden.

(2x 3)(x 1) (2x−3)(x−1) (3x 2)(x 1) (3x−2)(x−1)
The algebra tile configuration that represents the factors of 2x² + 5x + 3 must have a product of (2x + 3) and (x + 1)
How to model the factor?The expression is given as:
2x² + 5x + 3
Expand the expression
2x² + 5x + 3 = 2x² + 2x + 3x + 3
Factorize the expression
2x² + 5x + 3 = 2x(x + 1) + 3(x + 1)
Factor out x + 1
2x² + 5x + 3 = (2x + 3)(x + 1)
The above means that the algebra tile configuration that represents the factors of 2x² + 5x + 3 must have a product of (2x + 3) and (x + 1)

A and B are independent events. If P(A) = 0.50 and P(A and B) = 0.20, find P(B).
The independent events are illustrations of probability, and the value of P(B) is 0.40
How to determine the value of P(B)?The given parameters are:
P(A) = 0.50
P(A and B) = 0.20
Two events A and B are independent, if
P(A and B) = P(A) * P(B)
So, we have:
0.50 * P(B) = 0.20
Divide both sides by 0.50
P(B) = 0.40
Hence, the value of P(B) is 0.40

Not only would I like the value of x, but also I wonder how I’d go about solving this problem?
Answer:
x = 58
Step-by-step explanation:
This question can be solved by using the exterior angle property, which states that the exterior angle of a triangle = the sum of the two opposite interior angles.
62 lies on a line, so the exterior angle is 180 - 62, or 118 degrees.
Using the EAP, we can conclude the following:
(x + 2) + (x) = 118
2x + 2 = 118
2x = 116
x = 58
Hope this helps
Answer:
X=58
Step-by-step explanation:
1.) 62+2+2x=180
2) 64+2x=180 (add 62 and 2)
3) 2x=116 (subtract 64 from 180)
4)x=58 (divide 116 by 2 =58
Select the correct answer. A company offers its employees free recreational activities and gym memberships. Of the 200 employees, 95 employees registered for recreational activities, 80 employees registered for gym memberships, and 30 employees did not register at all. If an employee is chosen at random, what is the probability that the employee has registered for both recreational activities AND gym memberships?
Answer:
1/40
Step-by-step explanation:
95 + 80 + 30 = 205
205 - 200 = 5

If they sell their CDs for $10 each, how many must they sell before they make a profit?
