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 ≥ ?

answer the following
please give steps of how you got your answer
Answer: x^4
Step-by-step explanation:
1. Rewrite the expression in fraction form:
(3√x²)^6 = x^(2/3)^6
2 is the exponent, so when written in fraction form, it is the numerator. 3 is the index or root, so in fraction form it is the denominator.
2. Solve:
x^(2/3)^6 = x^(12/3) = x^4
Because the exponent 2/3 is raised to the power of 6, you can use the power rule, which basically just means that whenever an exponent is raised to an exponent, multiply them. So, 2/3 * 6 equals 12/3, and 12/3 equals 4, making your answer x^4.
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]

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.

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

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)

What is the slope of (-6, 1) and (2,5)?
Answer:
1/2
Step-by-step explanation:
To find the slope given two points, use the slope formula
m= ( y2-y1)/(x2-x1)
= ( 5-1)/(2--6)
= (5-1)/(2+6)
= 4/8
= 1/2
Answer:
slope = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 6, 1) and (x₂, y₂ ) = (2, 5)
m = [tex]\frac{5-1}{2+6}[/tex] = [tex]\frac{4}{8}[/tex] = [tex]\frac{1}{2}[/tex]

What is the weight of a square if a triangle weighs 4 grams? Explain your reasoning
Answer:
2 grams
Step-by-step explanation:
One can see that the given diagram is that of a balancing scale, meanig that both sides are equal to each other. Therefore, if one calls the weight of the triangle (t), then one can form an equation. Keep in mind that it is given that the square weighs (4) grams, and therefore, the square doesn't need a variable representation.
t + 4 + 4 = t + t + t + 4
Simplify,
t + 8 = 3t + 4
Inverse operations,
t + 8 = 3t + 4
-4 -4
t + 4 = 3t
-t -t
4 = 2t
/2 /2
2 = t
Answer:
2 grames
