Answer:

The graph of y=3(x+1)^2 can transformed by the parent function y=x^2. The graph of parent function will shift 1 unit left and vertically stretched by factor 3.

Step-by-step explanation:

The parent function is

y=x^2

This function can be transformed as

y=a(x+b)^2+c

Where a represents vertical stretch and compression, b represents horizontal shift and c represents vertical shift.

If a>0, then it shows vertical stretch and if a<0 then it shows vertical compression.

If b>0, then the graph of parent function shifts left by b units and if b<0 then the graph of parent function shifts right by b units.

If x>0, then the graph of parent function shifts upward by c units and if c<0 then the graph of parent function shifts downward by c units.

The given function is

y=3(x+1)^2

The value of a,b and c are 3, 1 and 0 respectively.

Therefore the graph of parent function will shift 1 unit left and vertically stretched by factor 3.

Liam is setting up folding chairs for a meeting. If he arranges the chairs in 6 rows of the same length, he
vladimir2022 [97]
We will need to have two equations here, having x as the missing length. We know that the chairs are in the same amount on each occasion, so each equation should be equal to the other.

This sets up a problem of:

6x + 7 = 4x + 13

7 and 13 being the leftover chairs and 6 and 4 being the rows. Let’s solve for x.

x = 3

Knowing this, we plug in x for one of the equations

6(3) + 7
18 + 7
25

Liam has 25 chairs.

I need help with this please!!!
Andru [333]

Answer:

U = \frac{TE}{3}

Step-by-step explanation:

Given

T = \frac{3U}{E}

Multiply both sides by E to clear the fraction

TE = 3U ( divide both sides by 3 )

\frac{TE}{3} = U
