Answer: C

Step-by-step explanation:

(-1,4) is the vertex. reflect (-2,3) and (-3,0) onto the other side of the y-axis. you may use desmos to plug in the functions and the answer will be C, since it goes through the points given and reflected.

Answer:

f(x)=4x(x-3)

Vertex=3/2, -9

Step-by-step explanation:

First, factorize it.

That is equal to 4x(x-3)

Therefore, x intercepts are 0 and 3, as  at least one of them need to be 0.

To find the vertex, first find the x of the vertex, which you can do by finding the average of the x intercepts, so it will be 3/2

Then, find the y, by making x in the original equation equal 3/2. This will give us -9 as the y.

The vertex will by 3/2, -9

2/3y + v = s solve for y
DanielleElmas [232]

Answer:

y = \frac{3s-3v}{2}

Step-by-step explanation:

Given

\frac{2}{3} y + v = s ( subtract v from both sides )

\frac{2}{3} y = s - v

Multiply through by 3 to clear the fraction

2y = 3s - 3v ( divide both sides by 2 )

y = \frac{3s-3v}{2}

The blueprint (a scale drawing used by architects and others) for Zahra’s new office measures `4` cm long and `2` cm wide. The s
Dimas [21]

Using scale concepts, it is found that the length of her office is of 10 ft, while the width is of 5 ft.

------------------------

  • The scale of 6 cm to 15 ft means that each <u>6 cm in the drawing represent 15 ft in actual dimensions</u>.
  • From this, a rule of three is applied to find the dimensions.

First, we find the actual length:

6 cm - 15 ft

4 cm - x ft

6x = 60

x = \frac{60}{6}

x = 10

The actual length is of 10 ft.

Then, we find the actual width:

6 cm - 15 ft

2 cm - x ft

6x = 30

x = \frac{30}{6}

x = 5

The actual width is of 5 ft.
