The number is -12 in the inequality x + 4y ≥ ?
What is an inequality?In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.
Given is a system of linear inequalities represented by the graph [attached]
We need to find the missing number,
y ≥ 2x – 2 and x + 4y ≥ ?
The linear equation with slope m and intercept c is given as follows.
y = mx + c.
The formula for slope of line with points (x₁, y₁) and (x₂, y₂) can be expressed as,
m = y₂ - y₁ / x₂ - x₁
The orange line intersects y-axis at (0, -2), therefore the y-intercept is -2.
The orange line intersects the points that are (1, 0) and (0, -2).
The slope of the line can be obtained as follows,
m = 2,
The slope of the line is m = 2.
Therefore, the orange line is y ≥ 2x – 2.
The blue line intersects y-axis at (0, -3), therefore the y-intercept is -3.
The blue line intersect the points that are (-4, -2) and (0, -3).
The slope of the line can be obtained as follows.
m = -1/4
The inequalities is x + 4y ≥ b passes through the point (0, -3).
0 + 4(-2) ≥ b
-12 ≥ b
Hence the number is -12 in the inequality x + 4y ≥ ?

Find f(-2) for the following function.
f(x)=3.6x-2
Answer:
f(- 2) = - 9.2
Step-by-step explanation:
To evaluate f(- 2) substitute x = - 2 into f(x) , that is
f(- 2) = 3.6(- 2) - 2 = - 7.2 - 2 = - 9.2
• There are 20 pounds of the mixture.
• Peanuts cost $2.95 per pound.
• Almonds cost $5.95 per pound.
• The mixture costs $4.00 per pound.
How many pounds of peanuts will there be?
Answer:
6.63 pounds
Step-by-step explanation:
Total pounds of mixture = 20
The contents of the mixture are; peanuts and almonds. Of which;
Peanuts cost = $2.95 per pound
Almonds cost = $5.95 per pound
The mixture cost = $4.00 per pound
Total cost of contents of the mixture = $8.90
The pounds of peanuts = [tex]\frac{2.95}{8.90}[/tex] x 20
= 6.63
Therefore, 6.63 pounds of peanuts was used in producing 20 pounds of the mixture.
Raymond used 36 cubes to build the first layer of a rectangular prism. The edge length of each cube was 1 inch. The finished prism had a total of 8 layers. What is the volume of Raymond’s prism in cubic inches?
Answer:
[tex]Volume=288in^{3}[/tex]
Step-by-step explanation:
Given
Base Cubes =36
Layers = 8
The number of base cubes represents the base area and the number of layers represents the height of the prism.
So, the volume is calculated as:
Volume = Base Cubes * Layers, i.e Base Area * Heights
Volume = [tex]36*8[/tex]
Volume = [tex]36in^{2} * 8 in[/tex]
Volume = [tex]288in^{2}[/tex]

7436 and k+ 80
+80 and k+36
and
36
Answer:
(C) j/j+80 and 36/k+36
Step-by-step explanation:
From the table attached :
Total Email (positive + negative) = j + 80
Number of positive Emails = j
Fraction of positive emails = (number of positive / total number of emails) = j / (j + 80)
Total phone calls (positive + negative) = 36 + k
Number of positive Emails = 36
Fraction of positive emails = (number of positive / total number of emails) = 36 / (k + 36)

Answer:
a. (5x - 2)° + (2x - 2)° + x° = 180°
b. m<113°,
m<K = 44°,
m<L = 23°
Step-by-step explanation:
Given:
m<J = (5x - 2)°
m<K = (2x - 2)°
m<L = x°
Required:
a. the equation to find x,
b. m<J, m<K, and m<L
Solution:
a. m<J + m<K + m<L = 180° (sum of triangle)
Substitute
(5x - 2)° + (2x - 2)° + x° = 180°
Solve for x
5x - 2 + 2x - 2 + x = 180
Add like terms
8x - 4 = 180
8x - 4 + 4 = 180 + 4
8x = 184
8x/8 = 184/8
x = 23°
b. ✔️m<J = (5x - 2)°
Plug in the value of x
m<J = 5(23) - 2 = 113°
✔️m<K = (2x - 2)° = 2(23) - 2
m<K = 44°
✔️m<L = x = 23°

The distance from the roller coaster to the food court on the map is 3.5 centimeters. If the scale on the map is 1 centimeter = 10 meters then find the actual distance to the food court?
Answer:
35 meters
Step-by-step explanation:
Since 1cm=10meters, we can do 3.5cm=how many meters?
To get from 1 to 10 we multiply by 10.
So we can do 3.5x10 to get 35 meters.

A student designed this sculpture. Using the dimensions on the sculpture, find the dimensions of each rectangular prism. Then calculate the volume of each prism.
Answer:
Prism Y
[tex]Height = 12in[/tex]
[tex]Length = 6in[/tex]
[tex]Width = 4in[/tex]
[tex]Volume = 288in^3[/tex]
Prism Z
[tex]Height = 18in[/tex]
[tex]Length =10in[/tex]
[tex]Width = 10in[/tex]
[tex]Volume = 1800in^3[/tex]
[tex]Total = 2088in^3[/tex]
Step-by-step explanation:
Given
See attachment for sculpture
Solving (a) The dimension and volume of Y
From the attachment
[tex]Height = 18 - 6[/tex]
18 in is the height of Z and 6in represents the length (height) of the unoccupied space by Y
So:
[tex]Height = 12in[/tex]
[tex]Length = 16 - 10[/tex]
16 in is the total length of the sculpture and 10 in represents the length of Z
So:
[tex]Length = 6in[/tex]
[tex]Width = 10 - 6[/tex]
10 in is the width of Z and 6in represents the length (width) of the unoccupied space by Y
So:
[tex]Width = 4in[/tex]
Hence, the dimension of Y is:
[tex]Height = 12in[/tex]
[tex]Length = 6in[/tex]
[tex]Width = 4in[/tex]
Volume is then calculated as:
[tex]Volume = Length * Width * Height[/tex]
[tex]Volume = 12in * 6in * 4in[/tex]
[tex]Volume = 288in^3[/tex]
Solving (b) The dimension and volume of Z
As identified in (a), the dimensions of Z are:
[tex]Height = 18in[/tex]
[tex]Length =10in[/tex]
[tex]Width = 10in[/tex]
Volume is then calculated as:
[tex]Volume = Length * Width * Height[/tex]
[tex]Volume = 18in * 10in * 10in[/tex]
[tex]Volume = 1800in^3[/tex]
Solving (c): Total volume of the sculpture.
To do this, we simply add up the volumes of Y and Z.
So, we have:
[tex]Total = 288in^3 + 1800in^3[/tex]
[tex]Total = 2088in^3[/tex]

Solve for possible values of x. 3x^2 = 18x
(0,0) and (6,0)
First we subtract 18x from both sides
3x²-18x=0
Factor out a 3x
3x(x-6)=0
This means that x is either 0 or 6
Answer:
3×^2=3^3
or; same base get canceled so
x^2=3
hence x=√3
Help!! Find the value of x
Answer:
x = 51
Step-by-step explanation:
The sum of internal angles for this rectangle is 360
x + 81 + 124 + 104 = 360 add like terms
x + 309 = 360 subtract 309 from both sides
x = 51
