Answer:

The age of Melanie is 29 years.

Step-by-step explanation:

Step 1 : Given statement

Melanie is 2 years older than Bill. Bill is 27 years old,

We need to find the age of Melanie.

Step 2 : We have given,

Melanie is 2 years older than Bill,

I.e. age of Melanie = Bill's age + 2

Step 3 : Age of Melanie = 27 + 2 ( Substituting )

Step 4 : 27 + 2 = 29 ( By adding ),

Step 5 : The age of Melanie is 29 years.

The y coordinate of the vertex of f (x)=-x^2+8x+7 is f(4)
azamat

Hello there.

To answer this question, we need to remember some properties about the vertex of quadratic functions.

Let f(x)=ax^2+bx+c,~a\neq0. Its vertex can be found on the coordinates (x_v,~y_v) such that x_v=-\dfrac{b}{2a} and y_v=-\dfrac{b^2}{4a}+c, in which y_v=f(x_v).

Using the coefficients given by the question, we get that:

x_v=-\dfrac{8}{2\cdot(-1)}\\\\\\ x_v=-\dfrac{8}{-2}\\\\\\ x_v=4

Thus, we have:

y=f(x_v)=f(4)

So the statement is true, because the x coordinate of the vertex of the function is equal to 4.~~\checkmark

Sliva [168]

Given parameters:

Total length of curtains bought = 20m

She used 8m for the living room

She used 7m for the dining room

unknown:

Quantity used for the kitchen = ?

Solution:

Quantity used for the kitchen = Total length - (living room + dining room)

Input the parameters given solve;

   Quantity used for the kitchen = 20 - (8 + 7) = 5m

The length of curtain used for the kitchen is 5m

Plsss help ASAP!!!!!!
Stells [14]

Answer:

Its either A or D because its reflection so that cancels out B and C

im not sure if this helps u or not but at lest it cancels out 2 of the options

The reflection of a horizontal line has the same result as a rotation of 90 degrees clockwise.

Step-by-step explanation:

When an image is rotated 90 degrees counterclockwise the shape is still congruent but in a different quadrant. The same is true when an image is reflected across a horizontal line.
