Answer:
The graph and the number line in the attached figure
Step-by-step explanation:
we have

Solve for x
subtract 7 both sides


Divide by -2 both sides
Remember
When you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
so

The solution is the interval (-8,∞)
All real numbers greater than -8
In a number line the solution is the shaded area at right of x=-8 (open circle)
The graph and the number line in the attached figure
(5x^2 + x - 4)(x + 2) = x(5x^2 + x - 4) + 2(5x^2 + x - 4) = 5x^3 + x^2 - 4x + 10x^2 + 2x - 8 = 5x^3 + 11x^2 - 2x - 8
Answer:
The number of students in each <u>van are 7</u> and number of students in each <u>bus are 23.</u>
Step-by-step explanation:
Let the number of students in each van be 'x' and number of students in each bus be 'y'.
Given:
<u>High School A:</u>
Number of students = 132
Number of buses = 3
Number of vans = 9
As per question,
-------1
<u>High School B:</u>
Number of students = 205
Number of buses = 8
Number of vans = 3
As per question,
-------2
Multiplying equation (2) by -3 and adding the result to equation (1), we get:


Now, plug in 23 for 'y' in equation (1) and solve for 'x'. This gives,

Therefore, the number of students in each van are 7 and number of students in each bus are 23
The answer is -2 (1-4x) = 3x + 8 is 2.
6^6 = 46656
Try a smaller example with 2 or 3 if that helps next time
