zavuch27 [327]

Answer:

156

Step-by-step explanation:

Let,

Sandwiches sold by Adam, Matt and Clinton = 2x, 7x and 3x

Total sandwiches = 2x + 7x + 3x

=> 12x

But its given that Matt sold 91 sandwiches

So,

7x = 91

x = 91/7

x = 13

=> Total sandwiches = 12x = 12(13) = 156

Explain how you could write a quadratic function in factored form that would have a vertex with an x-coordinate of 3 and two dis
skad [1K]
<span>The definition of quadratic function is given by:

</span>(1) \ f(x)=ax^{2}+bx+c \\ \\ where \ a, b, c \ are \ real \ values<span>

So the problem asks for two conditions:

<em>1. Write the quadratic function in factored form. </em>
<em>2. The vertex has an x-coordinate of 3.</em>

Then the equation (1) must be written as follows:

</span>f(x)=(x-m)(x-n) \\ \\ where \ m \ and \ n \ are \ the \ roots<span>

To satisfy the two conditions:

\frac{m+n}{2}=3

So we are free to choose the value of one root, say:

m=1

Thus:

n=6-1=5

Finally, the answer is:

f(x)=(x-1)(x-5)

The graph of this function is shown in the figure below.</span>

motikmotik

Answer:

-102.4 = v

Step-by-step explanation:

-15.9 = -3.1 + v/8

Add 3.1 to each side

-15.9 + 3.1 = -3.1+3.1 + v/8

-12.8 = v/8

Multiply each side by 8

-12.8 * 8 = v/8*8

-102.4 = v
