Michael makes a total of $400 from his land investment after calculating the total losses and gains from the lands sold.
Explanation:In order to find out the total money that Michael has made from his land investment, you need to calculate the losses and the gains individually. Michael sells two of his lands at a loss of $1,200 each, hence his total loss is 2 * $1,200 = $2,400. On the other hand, he sells the other two lands at a profit of $1,400 each, hence his total profit is 2 * $1,400 = $2,800.
To get the total money that he made on his investment, you subtract the total loss from the total profit. That is $2,800 (total profit) - $2,400 (total loss) = $400. Hence, Michael makes $400 on his investment.

Solve for x.
−1/3x≤−6
Answer:
x ≥ 18
hope this helps! <3
The solution of the inequality is x ≥ 18.
What is Inequality?Inequalities are mathematical formulas in which neither side is equal. Unlike equations, we compare two values in inequality. In between, the equal sign is substituted by a less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
We have −1/3x≤−6
Now, Multiply the inequality 3 from both side
-3x /3 ≤ -6 x 3
-x ≤ -18
Multiply (-1) to both side as
x ≥ 18.

What is the equation in point-slope form of a line that passes through the points (3, −5) and (−8, 4) ?

The equation of the line is y - 4 = (-9/11)[x + 8] which passes through the points (3, −5) and (−8, 4) option (A) is correct.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
It is given that:
The two points are: (3, −5) and (−8, 4)
As we know,
The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
The equation of the line:
y - 4 = (4+5)/(-8-3)[x + 8]
y - 4 = (-9/11)[x + 8]
Thus, the equation of the line is y - 4 = (-9/11)[x + 8] which passes through the points (3, −5) and (−8, 4) option (A) is correct.

Which of the following represents ninth root of x to the seventh power in exponential form?
Answer:
[tex]x^{\frac{7}{9}}[/tex]
Step-by-step explanation:
write ninth root of x to the seventh power in exponential form
[tex]\sqrt[9]{x^7}[/tex]
To write the radical in exponential form we use the below property
[tex]\sqrt[n]{x^a} = x^{\frac{a}{n}}[/tex]
The radical becomes the base of the fraction
[tex]\sqrt[9]{x^7}=x^{\frac{7}{9}}[/tex]
we cannot simplify the fraction.
The given expression in exponential form is

The students at Campbell High School have been planting trees as part of an ongoing service project. This month, they averaged 15 trees per participant. That is 150% more trees than their average the last time they did it. What was their average last time?
___ trees
Final answer:
The average number of trees planted by participants last time was 10 trees, calculated by understanding the percentage increase and using basic arithmetic.
Explanation:
The average number of trees planted by participants last time was 10 trees.
To solve this, we know that the current average is 15 trees per participant, which is 150% more than the last average. This means the current average is 250% of the last average. To find the last average, you divide the current average by 2.5 (250%), giving you 6. Then, you calculate 150% of 6, which equals 9. Adding 6 and 9 together gets you 15 trees, the current average, confirming the last average was 10 trees.

The volume formula of a cylinder is given as:
V = π r^2 h
So plugging in the value of the volume:
10 ft^3 = π r^2 h
h = 10 / (π r^2) ---> eqtn 1
The formula for the surface area of cylinder is:
s = 2 π r h + 2 π r^2
plugging in eqtn 1:
s = 2 π r [10 / (π r^2)] + 2 π r^2
s = (20 / r) + 2 π r^2 (ANSWER)

What is the missing term in the factorization
To find the missing term in the factorization, we rewrite the equation in the form of ax^2 + bx + c = 0, equate the coefficients and solve for the term. The missing term is -25.
Explanation:
To find the missing term in the factorization, we can rewrite the given equation in a general form of the quadratic equation like ax^2 + bx + c. In our case, this would be:12x^2 - 3(4x^2 - 10x + ?) = −75. Here, 'a' has a coefficient of 12, 'b' is -10 multiplied by 3 (the '3' outside the brackets), and 'c' is ? multiplied by 3. By equating the coefficients on both sides of the equation, we can solve for the missing term '?'. Therefore, the missing term is '? = -75 / 3' or '? = -25'.

The value of x is 61 after using the concept of vertically opposite angles option (A) 61 is correct.
What are vertically opposite angles?It is defined as the angles when two lines intersect each other and at the intersecting point, some pair of angles are formed which we call vertically opposite angles, as the name describes that they have vertically opposite angles.
It is given that:
The angles are shown in the picture.
As we know, from the definition of vertically opposite angles, the angles when two lines intersect each other and at the intersecting point.
The first angle = 2x + 24
The second angle = 146
Equating both the angles:
2x + 24 = 146
2x = 146 - 24
2x = 122
x = 122/2
x = 61
Thus, the value of x is 61 after using the concept of vertically opposite angles option (A) 61 is correct.

concert tickets cost $15 for general admission, but only $9 with a student ID. ticket sales total $4500. wirte and graph ab equation that models this situation. explain how to use your graph to find how many student tickets were sold if 200 general admission tickets were sold
The equation is given as 15x + 9y = 4500
The tickets sold when 200 are sold is y = 166.7
How to model the equation
The equation that models this would be
$15x + $9y = $4500
15x + 9y = 4500
If 200 admission tickets were sold we would have
15 * 200 + 9y = 4500
3000 + 9y = 4500
9y = 4500 - 3000
9y = 1500
y = 166.7 please approximate because tickets number has to be whole
The approximated total tickets that were sold is given as 167
