Which statements about the graph of the function f(x) = 2x2 – x – 6 are true? Check all that apply.

lbvjy [14]

Hello,

1: dom f=R
2: img f =R
3: 2x²-x-6=2(x²-2x/4+1/46)-6-1/8=2(x-1/4)²-49/8
Vertex=(1/4,-49,8)

4: roots are -3/2 and 2
2(x-1/4)²-49/8=1/8[(4x-1)²-49]=1/8*(4x+6)(4x-8)

5:
From the vertex to ∞
[-1/4 , ∞)

If I can paint a wall in 20 min and my friend can paint a wall in 30 min. How many minutes would it take for us to paint a wall

ra1l [238]

Answer: $12\ \text{min}$

Step-by-step explanation:

Given

It takes 20 min and 30 min for a person and his friend to paint a wall individually i.e.

In 1 min they cover $\frac{1}{20}$ part and $\frac{1}{30}$ part of wall respectively.

If the work together, 1 minute work is

$\Rightarrow \dfrac{1}{20}+\dfrac{1}{30}\\\\\Rightarrow \dfrac{3+2}{60}\\\\\Rightarrow \dfrac{5}{60}$

Time required will be reciprocal of it

$\Rightarrow \dfrac{60}{5}=12\ \text{min}$

Solve the equation. Write a justification for each step. <br>5m-3=22

balu736 [363]

Answer:

m=5

Step-by-step explanation:

5m-3=22

take 3 the other side by doing the opposite operation

5m= 22+3

5m= 25

then divide it by 5 on both sides to get the value of m.
5m÷5=25÷5
5and 5 cancels out and the answer becomes :

m=5
