Alan and his mom are planting vegetables in their garden. Alan has finished planting 4 rows of carrots so far and is planting new rows at a rate of 2 rows per hour. His mom has finished 7 rows of tomatoes and will continue planting at 1 row per hour. Once the pair get to the point where they have finished the same number of rows, they will take a break and decide what to plant next. How many rows will they each have completed? Write a system of equations, graph them, and type the solution.
Alan and his mom will each have completed 10 rows after 3 hours.
What do you mean by term Expressions ?An expression is a combination of numbers, variables, and/or operations (such as addition, subtraction, multiplication, division, exponents, and roots) that are grouped together to represent a value.
Let x be the number of hours it takes for Alan and his mom to have planted the same number of rows.
Alan will have planted 4 + 2x rows of carrots, and his mom will have planted 7 + x rows of tomatoes.
Setting these two expressions equal to each other gives:
4 + 2x = 7 + x
Solving for x, we get:
x = 3
Thus, after 3 hours, Alan will have planted:
4 + 2(3) = 10 rows of carrots
And his mom will have planted:
7 + (3) = 10 rows of tomatoes
Therefore, they will each have completed 10 rows of vegetables after 3 hours.
To graph these equations, we can plot them on a coordinate plane, where the x-axis represents the number of hours and the y-axis represents the number of rows planted.
Alan's equation is y = 2x + 4, and his mom's equation is y = x + 7.
The graph of these two equations intersect at the point (3, 10), which represents the moment when they have each planted 10 rows.
Therefore, Alan and his mom will each have completed 10 rows after 3 hours

(Thx for any help!)
The value of the length of line segment AB, in feet, that corresponds to the width of the television is,

We have to given that;
A new curved projection system for a small media room states the optimal viewing angle is 74° (m/ACB = 74°) when you sit 10 feet from the center of the TV (length of CD = 10 ft). The depth of the curved screen is 2 feet (length of DE = 2 ft).
Now, We can formulate;
CE = 10 - 2 = 8 feet
∠ACD = 74/2 = 37°
Hence, We can formulate;
tan 37° = AE / CE
0.75 = AE / 8
AE = 0.75 × 8
AE = 6
Hence, The value of the length of line segment AB, in feet, that corresponds to the width of the television is,
⇒ AB = 6 x 2
⇒ AB = 12 feet
Thus, The value of the length of line segment AB, in feet, that corresponds to the width of the television is,
⇒ 12 feet

Answer:
[tex]6\sqrt{2}+3\sqrt{10}[/tex]
Step-by-step explanation:
Use the Distributive Property. Remember that you can multiply the numbers under a square root whether or not they're the same. But you can ONLY add square roots when the square root part is the same.
[tex]\sqrt{3}(2\sqrt{6}+\sqrt{30})\\= \sqrt{3}(2\sqrt{6})+\sqrt{3}(\sqrt{30})\\=2\sqrt{18}+\sqrt{90}[/tex]
Simplify each square root part:
[tex]2\sqrt{18}+\sqrt{90}\\=2(3\sqrt{2})+3\sqrt{10}\\=6\sqrt{2}+3\sqrt{10}[/tex]
Since the square root parts are different, you cannot simplify any further.

Need the slope(m) of the function.
the y intercept of the function.
and the slope intercept form f(x)=mx+b of the function.
Answer:
We can calculate the slope by taking 2 points on the line. I took A(4,4) and B(-4,0), so we get m=1/2.
2. y-intercept is the point where a line crosses the y-axis which is (0,2)
3. We have f(x)=1/2x +b
By taking a particular point on the line,we get :
2=1/2(0)+b
==》 b=2
So the slope intercept form is
y=1/2x+2

B. The degree of a polynomial is: 4. It has 4 terms (4x², 3y, -6x^4y, and 4.); C ALWAYS result in another polynomial.
What is a Polynomial?A polynomial is a mathematical expression consisting of variables and coefficients that involves only the operations of addition, subtraction, and multiplication of non-negative integer exponents.
Part A:
Area of the rectangle = (7x - 1)(2x + 3) = 7x(2x + 3) -1(2x + 3)
= 14x² + 21x - 2x - 3
Combine like terms:
Area of the rectangle = 14x² + 19x - 3 (standard form)
Part B: Given the expression, 4x² + 3y - 6x^4y + 4,
The degree of a polynomial is the highest exponent of its variable.
Therefore, the degree is 4.
It has 4 terms, which are: 4x², 3y, -6x^4y, and 4.
Part C: When two polynomials are subtracted, multiplied, or added, it will ALWAYS result in another polynomial.

Answer:
If point A (-4,-5) of the trapezoid is reflected across the y-axis, the x-coordinate will change sign while the y-coordinate remains the same. This gives us the point A' (4, -5).
Next, if we shift the point A' by -6 units in the x-direction and 7 units in the y-direction, we get the new point A":
A" = (4 - 6, -5 + 7) = (-2, 2)

x = 6, x = 44; The zeros represent the number of monthly memberships where no profit is made.
x = 25, x = 361; The zeros represent the number of monthly memberships where no profit is made.
x = 25, x = 361; The zeros represent the number of monthly memberships that produces a maximum profit.
The zeros of the quadratic profit function are explained as:
x = 6, x = 44; The zeros represent the number of monthly memberships where no profit is made
How to find the zeros of a quadratic function?The quadratic function is given as:
f(x) = −x² + 50x − 264
The general form of expression of a quadratic function is:

Two mechanics worked on a car. The first mechanic worked for 20 hours, and the second mechanic worked for 15 hours. Together they charged a total of $2600. What was the rate charged per hour by each mechanic if the sum of the two rates was $155
per hour?
the first mechanic charged $55 per hour and the second mechanic charged $100 per hour. we solve this by forming equation by by given data.
what is equation ?
An equation is a mathematical statement that shows that two expressions are equal. It typically consists of two sides separated by an equal sign (=). The expressions on each side of the equal sign can contain variables,
In the given question,
Let's assume that the first mechanic charged x dollars per hour and the second mechanic charged y dollars per hour.
From the problem, we know that:
The first mechanic worked for 20 hours, so he charged 20x dollars.
The second mechanic worked for 15 hours, so he charged 15y dollars.
Together, they charged a total of $2600, so we have:
20x + 15y = 2600
The sum of the two rates was $155 per hour, so we have:
x + y = 155
We can use these two equations to solve for x and y. First, we can rewrite the second equation as:
y = 155 - x
Then, we can substitute this expression for y into the first equation:
20x + 15(155 - x) = 2600
Simplifying and solving for x, we get:
20x + 2325 - 15x = 2600
5x = 275
x = 55
Now that we know x, we can use the second equation to find y:
y = 155 - x = 155 - 55 = 100
Therefore, the first mechanic charged $55 per hour and the second mechanic charged $100 per hour.

A local city government wants to display the ages of the city citizen. Would it be better to organize the data using a dot plot or a histogram, and why?
If local city government wants to display the ages of the city citizen, It would be better to organize the data using a histogram.
A histogram is a graph that shows the distribution of a set of continuous data. The ages of city citizens can be considered as continuous data, as there are many possible values for age within a certain range.
A dot plot, on the other hand, is a graph that shows the distribution of a set of discrete data. Discrete data are values that can only take on specific, isolated values, like shoe sizes or the number of siblings a person has.
A histogram would be more effective for displaying the distribution of the ages of city citizens because it can show the range of ages in a more continuous manner, and provide a more precise representation of the frequency of the different age groups.
A dot plot, on the other hand, would be less effective, as it could be difficult to represent every age value as a single dot, and the resulting graph may not provide a clear indication of the distribution of ages.
