Answer:
Question 3: M = -2, B = 1
Question 4: M = [tex]\frac{2}{5}[/tex], B = -6
Question 5: M = 1, B = -5
Question 6: M = [tex]\frac{1}{3}[/tex], B = 4
Step-by-step explanation:
Question 3 explanation: 2x + y < 1 ⇒ y < -2x + 1 ⇒ M = -2, B = 1
Question 4 explanation: 2x - 5y ≥ 30 ⇒ -5y ≥ -2x + 30 ⇒ y ≤ [tex]\frac{2}{5}[/tex]x - 6 ⇒ M = [tex]\frac{2}{5}[/tex], B = -6
Question 5 explanation: x - y > 5 ⇒ -y > -x + 5 ⇒ y < x - 5 ⇒ M = 1, B = -5
Question 6 explanation: 2x - 6y ≤ -24 ⇒ -6y ≤ -2x - 24 ⇒ y ≥ [tex]\frac{1}{3}[/tex]x + 4 ⇒ M = [tex]\frac{1}{3}[/tex], B = 4

In Which Form is this linear inequality?
Answer: A
Step-by-step explanation:
Find the area of a square that has a side length of 4.8 cm.
A=23.04cm² , A=a2=4.82=23.04cm²
Answer: 23.04 cm.
Step-by-step explanation:
To find the area of something, we use the equation l x w, or length x width.
A square has 4 sides, and all 4 sides are equal. If the length of a square is 4.8, then the width is also 4.8 since all 4 sides of a square are equal.
Since we're using the equation l x w to find the area of the square, we have to multiply 4.8 x 4.8.
4.8 x 4.8 = 23.04.
Therefore, the area of the square is 23.04 centimeters!
Robin braided g inches of a friendship bracelet. Olivia braided 12 less than 1/3 the number of inches Robin braided. Select all of the expressions that represent the total number of inches braided by Robin and Olivia.
A. 2/3g - 12
B. 4/3g - 12
C. 4(1/3g - 3)
D. 1/3(4g - 36)
E. g + ( 1/3g - 12)
Answer: C. [tex]4(\dfrac13g-3)[/tex]
Step-by-step explanation:
Given: Robin braided g inches of a friendship bracelet.
Number of inches braided by Olivia = [tex]\dfrac13g-12[/tex]
The total number of inches braided by Robin and Olivia = Number of inches braided by Robin + Number of inches braided by Olivia
[tex]=g+\dfrac13g-12\\\\=\dfrac43g-12\\\\\=4(\dfrac13g-3)[/tex]
The total number of inches braided by Robin and Olivia = [tex]4(\dfrac13g-3)[/tex]
Hence, C. is the correct option.

Which of the following describes the correct first step in solving the equation 2x - 7 = 5?
Answer:
you need to post a picture of the options, but the answer is add seven to both sides.
Step-by-step explanation:
Answer:
add 7 to 5
Step-by-step explanation:
1. 2x - 7 = 5
2. 2x = 5 + 7 (reverse the 7)
3. 2x = 12 (simplify)
4. 12/2 (divide number by the unknown value)
5. x= 6 (solve?)
6. 2(6) - 7 = 5 (CHECK)

a person bikes 2 1/2 miles at a constant rate in 1/8 of an hour what distance , does the person bikes in an hour.
Answer:
20 miles
Step-by-step explanation:
We are given that
Person traveled total distance by bike=2 1/2 miles
Person traveled total distance by bike==[tex]2+\frac{1}{2}=2.5miles[/tex]
Time taken by person ,t=1/8 hour
We have to find the distance traveled by person bike in an hour.
We know that
Rate==[tex]\frac{Distance}{time}[/tex]
Using the formula
Rate=[tex]\frac{2.5}{\frac{1}{8}}[/tex]miles/hr
Rate=20mph
In 1 hour person bike traveled distance=20 miles

A rectangular prism has a base with an area of 13 square units and a volume of
109.2 cubic units. The equation shown gives the height, h, in units, of the prism.
13h = 109.2
What is the height, in units, of the prism?
Answer:
Isolate the variable and simplify.
Step-by-step explanation:
13h = 109.2
h = 109.2 ÷ 13
h = 8.4
Your answer would be 8.4 units.
Don't forget units! :)

Which function has a greater rate of change? Function A: x 1.5 2.5 3.5 4.5 5.5 y 5 0 –5 –10 –15 Function B: y = –4.5x + 15 Function A has a rate of change of –5 and Function B has a rate of change of –4.5, so Function A has a greater rate of change. Function A has a rate of change of 5 and Function B has a rate of change of 4.5, so Function A has a greater rate of change. Function A has a rate of change of 5 and Function B has a rate of change of 4.5, so Function B has a greater rate of change. Function A has a rate of change of –5 and Function B has a rate of change of –4.5, so Function B has a greater rate of
Answer:
Function A has a rate of change of -5 and Function B has a rate of change of -4.5, so Function B has a greater rate of
Step-by-step explanation:
Function A:
[tex]\begin{array}{cccccc}x & {1.5} & {2.5} & {3.5} & {4.5} & {5.5} \ \\ y & {5} & {0} & {-5} & {-10} & {-15} \ \end{array}[/tex]
Function B:
[tex]y = -4.5x + 15[/tex]
Required
Which has a greater rate of change
The rate of change of function A is calculated as thus:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where:
[tex](x_1,y_1) = (1.5,5)[/tex]
[tex](x_2,y_2) = (2.5,0)[/tex]
So, we have:
[tex]m = \frac{0-5}{2.5 - 1.5}[/tex]
[tex]m = \frac{-5}{1}[/tex]
[tex]m = -5[/tex]
For function B
The general function is:
[tex]y = mx + b[/tex]
Where
m is the rate of change
By comparing [tex]y = mx + b[/tex] to [tex]y = -4.5x + 15[/tex]
[tex]m = -4.5[/tex]
So, we have that:
Function A has a rate of -5; function B has a rate of -4.5.
By comparison: -4.5 is greater than 5
Hence, function B has a greater rate.

Answer:
3.375 in³
Step-by-step explanation:
1) V = l x w x h
2) Since a cube has all equal sides, then our equation would be V = 1.5³
3) V = 1.5³ = 3.375 in³
Answer:
3.375 in^3.
Step-by-step explanation:
All sides have the same length so the volume = 1.5^3
= 3.375 in^3.

Break it apart into rectangles/squares where you can figure out what the length of at least two sides are for each.
Then multiply and get the area of the smaller area.
Then add the areas up.
You're basically just breaking it down into smaller shapes, then adding the different parts back together.
