Part A: Solve the following equation: 8 + 2(x - 3) = 3x - 3 (2 points)
Part B: Solve the following absolute value equation: |2x + 6| = 8 (4 points)
Part C: Solve the following inequality: -5(x + 1) > 30 (2 points)
Part D: f(x) = 4x - 3. Find f(5) (2 points)
Answer:
Part A) x = -3
Part B) x = 1, x = -7
Part C) x < -7
Part D) 2
Step-by-step explanation:
Part A)
2(x - 3) = 3x - 3
open the parenthesis
2 * x - 2 * 3 = 3x - 3
2x - 6 = 3x - 3
subtract 2x from both sides
2x - 2x - 6 = 3x - 2x - 3
-6 = x - 3
add 3 to both sides
-6 + 3 = x
-3 = x
Part B)
|2x + 6| = 8
split this into two equations:
2x + 6 = 8
&
2x + 6 = -8
2x + 6 = 8
2x = 8-6
2x = 2
x = 1
2x + 6 = -8
2x = -8 - 6
2x = -14
x = -7
Part C)-5(x + 1) > 30
open the parenthesis
-5x - 5 > 30
add 5 to both sides
-5x > 35
divide both sides by -5
x > -7
since you divided by a negative, flip the sign.
x < -7
Part D)
f(x) = 4x - 3
substitute x for 5
5 = 4x - 3
5 + 3 = 4x
8 = 4x
2 = x

Answer:
D is the answer
Step-by-step explanation:
A filled circle means "or equal to" in which this case the symbol is less than or equal to, making the dot filled. Since 2 is greater than x, the line would start on the two and continue farther down the line to show that anything 2 or greater is more than x.

Find the slope, x-intercept, and y-intercept of the equation y = 10x - 20.
Answer:
slope=10, y-int=-20. x-int=2
Step-by-step explanation:
The equation y=10x-20 is in slope-intercept form, or y=mx+b with m being the slope and b being the y-int. In this scenarion, the m(the slope) is 10 and the b(the y-int) is -20. For the x-int, you have to find out what x is when y=0 and vice versa for the y-int. In this case, 0=10x-20 so x=2. Therefor the x-int is 2.

For what value of k will the points (3,5) and (9,k) represent a proportional relationship?
Answer:
k = 15
Step-by-step explanation:
For a proportional relationship to exist then for both points
k = [tex]\frac{y}{x}[/tex] ← k is the constant of proportion, that is
[tex]\frac{5}{3}[/tex] = [tex]\frac{k}{9}[/tex] ( cross- multiply )
3k = 45 ( divide both sides by 3 )
k = 15

The local ice cream shop surveyed the customers to see which flavor of ice cream is most popular 125 people choose chocolate as their favorite which represents 25% of the customers surveyed how many total customers were surveyed A.425 B.20 C.500 D.32
Answer:
500
Step-by-step explanation:
Let there were a total of x number of customers.
As 125customers choose chocolate flavor as their favorite which is 25% of the total customers surveyed, so
25% of x = 125
0.25x=125
x=125/0.25=500
Therefore, the total number of customers surveyed is 500.

Lesson 15 Homework 5.2
3. String A is 35 centimeters long. String B is 5 times as long as String A. Both are necessary to create a
decorative bottle. Find the total length of string needed for 17 identical decorative bottles. Express your
answer in meters.

Answer:
The total length of string needed for 17 identical decorative bottles is 35.70 meters
Step-by-step explanation:
Let us solve the question
∵ String A is 35 centimeters long
∵ String B is 5 times as long as String A
→ Multiply the length of A by 5 to get the length of B
∴ The length of string B = 35 × 5 = 175 cm
∵ Both are necessary to create a decorative bottle
∴ The length needed for 1 bottle = 35 + 175 = 210 cm
∴ Each bottle needs 210 cm to be decorated
∵ There are 17 identical bottles
→ Multiply the length needed for 1 bottle by 17
∴ The total length needed = 17 × 210 = 3570 cm
∴ The total length needed to decorate 17 bottles is 3570 cm
∵ 1 meter = 100 centimeter
→ Divide the total length by 100 to express it in meters
∴ 3570 cm ÷ 100 = 35.70 m
The total length of string needed for 17 identical decorative bottles is 35.70 meters

How many four-digit personal identification numbers (PIN) are possible if the PIN cannot begin with a 0 and the PIN
must be an odd number?
a. 5,000
b. 4,500
c. 3,600
d. 500
Answer:
BStep-by-step explanation:
How many four-digit personal identification numbers (PIN) are possible if the PIN cannot begin with a 0 and the PIN must be an odd number?
ANSWER B: 4,500
The number of 4 digit personal identification numbers (PIN) is 4500
What is a PIN?A PIN is a security code that is used for verifying identities
There are 10 numerical digits i.e. 0 - 9
Since the 4 digit personal identification numbers (PIN) cannot begin with 0, then the first character can take any of 9 digits
The other three characters can take any of the 10 digits.
So, the number of PIN is:
PIN = 9 * 10 * 10 * 10/2
Expand
PIN = 4500
Hence, the number of 4 digit personal identification numbers (PIN) is 4500
