Inequalities help us to compare two unequal expressions. The correct option is B.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.
It is mostly denoted by the symbol <, >, ≤, and ≥.
For the given inequalities, the graph can be plotted as shown below. Now when the coordinates have been plotted the point that will satisfy both the inequalities is (-2,2).
Hence, the correct option is B.

Daniel’s agent made
.
Daniel and the agent made a total of
from the show.
Answer:
Amount in Blank total = $160
Amount of money Daniel’s agent made = $40
Amount of money Daniel and the agent made
from the show = $160
Step-by-step explanation:
this question is based on the calculation of percentages
so,
it is is given in the question that -
Daniel is a singer, and he promises his agent that he will give him a 25% commission based on what he makes from a show.
After paying the agent, Daniel takes home = $120
so,
let 'x' is the total amount of money that Daniel earned form the show
it is also given that Daniel promised to give 25 % to his agent from what he earned from the show
so, percentage of money left to the Daniel is
100-25 = 75%
therefore according to the question,
75percent of the x = $120
75/100×(x) = 120
3/4×(x) = 120
3x = 120×4
3x = 480
x = $160
so the total amount of money Daniel earned from the show is $160
Now we know that Daniel’s agent made 25% of the total amount of money earned from the show
therefore
25percent of 160 = Daniel’s agent made
25/100 ×160 = Daniel’s agent made
$40 = Daniel’s agent made
so the amount of money earned by Daniel’s agent made is $40

If the domain of the square root function f(x) is , which statement must be true?7 is subtracted from the x-term inside the radical.The radical is multiplied by a negative number.7 is added to the radical term.The x-term inside the radical has a negative coefficient.
The question was incomplete. Below you will find the missing content.
The square root function f(x) is x <= 7
Options are :
A. 7 is subtracted from the x-term inside the radical.
B. The radical is multiplied by a negative number.
C. 7 is added to the radical term.
D. The x-term inside the radical has a negative coefficient.
Option D is correct, which is : The x-term inside the radical has a negative coefficient.
Given, the domain of the square root function f(x) is x <= 7
Consider the function y = √x.
The domain of this function is x ≥ 0 and the range is y ≥ 0.
The expression inside the radical must be greater than or equal to zero.
Now, if x ≤ 7
x - 7 ≤ 0
7 - x ≥ 0
And the function y = √(7-x) will have the domain x ≤ 7.
This implies that the x-term inside the radical has a negative coefficient.
Therefore, the statement that the x-term inside the radical has a negative coefficient must be true.

Answer:
3d²
Step-by-step explanation:
Hello!
To simplify, we combine the like terms by adding them.
Like termsLike terms are terms with the same variable and degree. A degree is a power to which the term is raised. Like terms can have numerical coefficients. For example, a coefficient of 4 to x² would mean 4 times x².
We can see that the variable d² is common throughout the three terms, meaning they are like terms. We can simply add and subtract them.
Simplify4d² - 6d² + 5d²-2d² + 5d²3d²The simplified form is 3d².

The different values that could be be the greatest common divisor of the two integers are; 1, 2, 3, 4, 6
How to find the greatest common divisor?
Let the numbers be a, b. Thus, the product of the GCD(a, b) and the LCM(a, b) will be ab.
Now, for us to get something to be a factor of the GCD we need to make it be a factor of both a, b. Thus, its' square must be a factor of 180.
Therefore, the only numbers whose square is a factor of 1800 are 1, 2, 3, 4, 6 and as such they are the only GCDs possible.

The system of equation can be used to find the root of the equation is y= x³-4x² +2x and y=0 , y=4x² and y= x³+2x
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
y=-4x²
y= x³+2x
By equating the above equation we have
-4x²=x³+2x
Now, y= x³-4x² +2x
and y=0
By equating the above equation we have
x³-4x² +2x=0
y=4x²
y= -x³-2x
By equating the above equation we have
4x²=-x³-2x
Lastly,
y=4x²
y= x³+2x
By equating the above equation we have
4x²=x³+2x

A small company manufactures picnic tables. The daily fixed cost is 1,200 and the variable cost is $45 per table. How many picnic tables can be produced for a total daily cost of 4,800.
Using a linear function, it is found that 80 picnic tables can be produced for a total daily cost of 4,800.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Considering the daily fixed cost of 1200 as the y-intercept, and the variable cost of 45 as the slope, the linear function for the cost of producing n picnic tables is given by:
C(n) = 1200 + 45n.
Now, we have to solve for n when C(n) = 4800, hence:
1200 + 45n = 4800
45n = 3600
n = 3600/45
n = 80.
