Answer:

(3y + 1)(y + 4)

Step-by-step explanation:

3y^(2) + 13y + 4 = 3y^(2) + 12y + y + 4 = 3y(y + 4) + 1(y + 4) = (3y + 1)(y + 4)

Zepler [3.9K]

Answer:

  • D.  l = 3  ||  4 < c < y   ||  8l + 7.5c ≥ 70

Step-by-step explanation:

<h3>Work at library</h3>
  • Time  = 3 hours ⇒ l = 3
  • Payment = $8 per hour
  • Total payment = 8l
<h3>Work at coffee shop</h3>
  • Time = between 4 and 7 hours ⇒ 4 < c < 7
  • Payment = $7.5 per hour
  • Total payment = 7.5c

Target income = at least $70 daily  

<u>So the system as per above parameters:</u>

  • l = 3
  • 4 < c < y
  • 8l + 7.5c ≥ 70

Correct option is D

Which is true regarding the graphed function f(x)?
Sladkaya [172]
<h2>Explanation:</h2>

Hello! Remember you have to write complete questions in order to get good and exact answers. Here I'll assume the graphed function comes from:

f(x)=\left(x-4\right)^{2}+5

So this is the equation of a parabola that opens upward and whose vertex lies on the point:

V(4,5)

The graph of this function is shown below. Which is true regarding the graphed function f(x)?

  • It is true that the domain is the set of all real numbers because this is a polynomial function.

  • It is true that the range is the set of all real numbers such that y ≥ 5

  • It is true that this parabola opens upward

  • It is true that it doesn't cut the x-axis
