The equation to describe the situation is 8p = 56

The number of packs of hot dog the neighbour bought is 7

p = number of packs of hot dogs

8 hot dogs are in each pack of hot dogs.

Altogether, they have 56 hot dogs. Therefore,

The equation to describe the situation is as follows:

  • 8p = 56

The number of packs the neighbour bought can be calculated as follows:

<h3>Equation model:</h3>8p = 56

divide both sides by 8

8p / 8 = 56 / 8

p = 7

Find the vertex of the graph of f(x) = x2 + 4x - 5.
Fofino [41]
You can solve this in two ways.

1. Graphical. Plot the graph for x between -5 and 1 (see attachement).
The vertex of the graph is the peak of the curve, which has the coordinates x=-2, y=-9.

2. Analytical. Calculate the derivative of the function f(x)
\frac{df}{dx}=2x+4
Solve the equation:
2x+4=0
will give the solution x=-2.
Replace x=-2 in the f(x) function and you'll get the value of y:
(-2)^2+4 \cdot (-2)-5=4-8-5=-9

You get the same answer: x=-2, y=-9

So the answer is

Find the surface area
mote1985 [20]

Answer:

Step-by-step explanation:

l = 7 in

w = 11 in

h = 5 in

Surface area = 2*(lw +wh +hl)

        = 2*(7*11 + 11*5 + 5*7)

       = 2* (77+ 55 + 35)

     = 2 * 167

     = 334 square inches

2. Two angles have a common vertex but no common side. How can you tell whether the angles are vertical angles?
Maksim231197 [3]

Explanation:

The angles are <em>vertical angles</em> if the opposites of the rays forming one of the angles are the rays forming the other angle.

More formally, if V is the common vertex, and ...

  • R is a point on one of the rays forming Angle 1
  • S is a point on the ray that is the opposite of ray VR
  • T is a point on the other ray forming Angle 1
  • U is a point on the ray that is the opposite of ray VT

Then angle RVT and angle SVU are vertical angles.

___

Another way to say this is that points R, V, S are collinear, as are points T, V, U, and the two angles of interest are RVT and SVU.

If the above conditions cannot be met, then the angles are not vertical angles.
