The inequality [tex]\(-6x \geq 30\)[/tex] is equivalent to [tex]\(x \leq -5\)[/tex]. Therefore, the correct answer is option d: [tex]\(x \leq -5\)[/tex].
To solve the inequality [tex]\(-6x \geq 30\)[/tex] and find its equivalent form, follow these steps:
1. Write down the original inequality:
[tex]\[ -6x \geq 30 \][/tex]
2. Isolate [tex]\(x\)[/tex] by dividing both sides of the inequality by [tex]\(-6\)[/tex]:
- Note that when dividing both sides of an inequality by a negative number, the direction of the inequality sign must be reversed.
[tex]\[ \frac{-6x}{-6} \leq \frac{30}{-6} \][/tex]
3. Simplify both sides:
[tex]\[ x \leq -5 \][/tex]
So, the equivalent inequality to [tex]\(-6x \geq 30\)[/tex] is [tex]\(x \leq -5\)[/tex].
Therefore, the correct answer is:
[tex]\[\boxed{\text{d: } x \leq -5}\][/tex]

In the diagram, △ABC ≅ △WRS. What is the perimeter of △WRS?
10 units
11 units
12 units
13 units
Answer: Third option is correct.
Step-by-step explanation:
Since we have given that
△ABC ≅ △WRS
So, Perimeter of △ABC is given by
AB+BC+CA
here, AB = 3 units
BC = 4 units
AC = x
By pythagorus theorem, we get that
[tex]AC^2=AB^2+BC^2\\\\x^2=3^2+4^2\\\\x^2=9+16\\\\x^2=25\\\\x=\sqrt{25}\\\\x=5\ units[/tex]
So, perimeter of △ABC is
3+4+5=12 units
So, the perimeter of △WRS is also 12 units as they are similar triangles .
Hence, Third option is correct.

Domingo works 40 hours per week as a tire store manager . If he made $29640 last year. how much he made per hour
A. $14.25
B. $16.50
C. $12.25
D.$11.00
Domingo made $14.25 per hour last year by dividing his annual income of $29640 by the total hours worked in the year, which is 2080 hours (40 hours/week imes 52 weeks).
Explanation:To calculate how much Domingo made per hour, divide his annual income by the total number of hours worked in a year. Domingo works 40 hours per week, and there are 52 weeks in a year, so the total hours worked in a year is 40 hours/week imes 52 weeks/year = 2080 hours/year.
The formula to find the hourly wage is:
Hourly Wage = Annual Income / Total Hours Worked
Thus, Domingo's hourly wage would be:
$29640 / 2080 hours = $14.25 per hour.
Therefore, the correct answer is A. $14.25.

Suppose the graph of a cubic polynomial function has the same zeroes and passes through the coordinate (0, –5).
Write the equation of this cubic polynomial function.
Recall that the zeroes are (2, 0), (3, 0), and (5, 0). What is the y-intercept of this graph?
-5
The linear factors of the cubic are
The cubic polynomial equation which passes through the coordinate (0,-5) and whose zeroes are (2 , 0), (3 , 0), and (5 , 0) is: [tex]y = \dfrac{1}{6}(x-2)(x-3)(x-5)[/tex] and it can be determine by arithmetic operations.
Given :
A cubic polynomial whose zeroes are (2 , 0), (3 , 0), and (5 , 0).Cubic polynomial equation passes through (0 , -5).Arithmetic operations can be used to determine the cubic polynomial equation. The generalised cubic polynomial equation is given by:
[tex]y = K(x-a)(x-b)(x-c)[/tex]
Where, K is constant and a, b, and c are the zeroes of the cubic polynomial equation. Therefore, the value of a, b, and c are 2, 3, and 5 respectively.
[tex]y = K(x-2)(x-3)(x-5)[/tex] ----- (1)
It is given that cubic polynomial equation passes through (0 , -5). So, put x = 0 and y = -5 in equation (1) to evaluate the value of K.
[tex]-5=K(0-2)(0-3)(0-5)[/tex]
[tex]5=30K[/tex]
[tex]K = \dfrac{1}{6}[/tex]
Therefore the cubic polynomial equation is given by:
[tex]y = \dfrac{1}{6}(x-2)(x-3)(x-5)[/tex]

BRAINIEST WILL BE GIVEN------ University Law School accepts 2 out of every 15 applicants. If the school accepts 180 students, find how many applicants they received.
Step 1: Assign variable for the unknown that we need to find.
Let ' x ' be the number of applicants received by University Law School.
Step 2: Set up an equation based on the information given.
"University Law School accepts 2 out of every 15 applicants. If the school accepts 180 students, find how many applicants they received"
[tex] \frac{Accepted \; application}{Applied \; applicants} =\frac{2}{15} =\frac{180}{x} [/tex]
Step 3: Solving the equation
[tex] \frac{2}{15} =\frac{180}{x} \\ Cross \; Multiply\\ \\ 2x=15(180)\\ 2x=2700\\ Divide\; by\; 2\; on\; both\; sides\\ \\ \frac{2x}{2} =\frac{2700}{2} \\ Simplifying\; fraction\; on\; both\; sides\\ \\ x=1350 [/tex]
Conclusion:
The number of applicants received by University Law School is 1350.
The volume of a rectangular box is found by multiplying its length, width, and height: V = lwh. A certain box has a volume of b 3 + 3b 2 - 4b - 12. Factor the four-term polynomial to find the dimensions of the box. Hint: Use factoring by grouping to factor the four term polynomial first.
Answer:
The dimensions of the box are (b+3), (b-2) and (b+2).
Step-by-step explanation:
The volume of a rectangular box is
[tex]V=l\times w\times h[/tex]
The volume of a certain box is
[tex]V=b^3+3b^2-4b-12[/tex]
First of all find the factors of above expression by grouping method.
[tex]V=b^2(b+3)-4(b+3)[/tex]
[tex]V=(b+3)(b^2-4)[/tex]
[tex]V=(b+3)(b^2-2^2)[/tex]
[tex]V=(b+3)(b-2)(b+2)[/tex] [tex][\because a^2-b^2=(a+b)(a-b)][/tex]
Volume of a rectangle is the product of its dimensions, therefore the dimensions of the box are (b+3), (b-2) and (b+2).
