Answer: Sure, I can help you with that!
Part A: To solve the inequality −6(x − 3) > 42, we first need to distribute the -6 to the expression inside the parentheses:
-6(x - 3) > 42 -6x + 18 > 42
Next, we’ll subtract 18 from both sides:
-6x > 24
Finally, we’ll divide both sides by -6. Since we’re dividing by a negative number, we need to flip the inequality sign:
x < -4
Therefore, the solution to the inequality is x < -4.
Part B: To graph the solution to this inequality on a number line, we’ll start by drawing an open circle at -4 (since x is not equal to -4). Then, we’ll draw an arrow pointing to the left of -4 to indicate that all values less than -4 are solutions to the inequality.
Part C: To find two values that would make the inequality true, we can choose any two values less than -4 and substitute them into the original inequality. For example, if we choose x = -5, then:
-6(-5 - 3) > 42 -6(-8) > 42 48 > 42
Since 48 is greater than 42, this confirms that x = -5 is a solution to the inequality. Similarly, if we choose x = -10, then:
-6(-10 - 3) > 42 -6(-13) > 42 78 > 42
Since 78 is also greater than 42, this confirms that x = -10 is also a solution to the inequality.
I hope this helps!

Answer:
many solutions
Step-by-step explanation:
4n + 6 = 4 + 2 + 4n
We try to solve for n
we try to get the variable alone
4n + 6 = 4 + 2 + 4n
combine like terms
4n + 6 = 6 + 4n
subtract 4n from both sides
6=6
If we arrive at a true statement like 5=5 then the equation has infinitely many soltions
We arrived at a true statement 6=6 so infinitely many solutions
Answer:
see explanation
Step-by-step explanation:
given the function
f(x) = x² - 6x + 8
(a)
to find the y- intercept , let x = 0 in f(x)
f(0) = 0² - 6(0) + 8 = 0 - 0 + 8 = 8 ← y- intercept
(b)
to find the x- intercepts , let f(x) = 0 , that is
x² - 6x + 8 = 0 ← in standard form
(x - 2)(x - 4) = 0 ← in factored form
equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2
x - 4 = 0 ⇒ x = 4
the x- intercepts are x = 2 and x = 4 or (0, 2 ), (0, 4 ) in coordinate form
(c)
given a quadratic in standard form
f(x) = ax² + bx + c ( a ≠ 0 )
then the x- coordinate of the vertex is
= -
f(x) = x² - 6x + 8 ← is in standard form
with a = 1 and b = - 6 , then
= - = - (- 3) = 3
evaluate f(3) for corresponding y- coordinate
f(3) = 3² - 6(3) + 8 = 9 - 18 + 8 = - 9 + 8 = - 1
vertex = (3, - 1 )
(d)
the axis of symmetry is a vertical line , passing through the vertex with equation
x = c ( c is the value of the x- coordinate of the vertex )
equation of axis of symmetry is then x = 3
b) The company takes 600 photos before selecting which ones to use for its calendars.
c) The company expects to sell 600 calendars each month.
d) The company will sell the calendars for $6.00 each.
Answer:
The correct option is a.
Step-by-step explanation:
The average cost function is
Where x is the number of calendars produced.
The average cost formula is
Therefore the total cost is defined b the function
Here 600 is the initial cost and the cost each unit is 2.
Initial cost is the fixed cost which occurs at zero level of productivity.
The company spends $600 on a new computer and printer before beginning the project. The option (a) is correct.
