Answer:
it depends
Step-by-step explanation:
sometimes a teacher will accept "there are infinite solutions" but if you cant you may need to do something else(this applies to basically everything)
for an example lets use x=1
(1,+infinity)
or
(1,-infinity)
(this is being graphed.) (this may not apply to everything)
i hope this helps

Answer:
the answer for x<5
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
−4<−4x+16
Step 2: Flip the equation.
−4x+16>−4
Step 3: Subtract 16 from both sides.
−4x+16−16>−4−16
−4x>−20
Step 4: Divide both sides by -4.
−4x
−4
>
−20

x<5
Answer:
B
Step-by-step explanation:
The maximum value of the function is the y- coordinate of the vertex.
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
= - 
y = - 3x² - 15x + 9 ← is in standard form
with a = - 3 and b = - 15, thus
= -
= - 2.5
Substitute x = - 2.5 into the equation for y- coordinate of vertex
y = - 3(- 2.5)² - 15(- 2.5) + 9 = - 18.75 + 37.5 + 9 = 27.75 → B
$250 x 0.25 = 62.5
62.5 + 250 == $312.50
you will pay $312.50
