Answer:

The number is 30.

Step-by-step explanation:

The number is x.

"Take me seven times over" 7x

"And add a fifty" 7x + 50

"To reach a triple century You still need forty!" 7x + 50 + 40 = 300

7x + 90 = 300

7x = 210

x = 30

The inequality equation represented by the parabola graph is;

y < (x - 2)(x - 8)

<h3>How to Interpret a Quadratic Graph?</h3>

We are told that the zeros of a parabola are 2 and 8. This means that the roots of the quadratic equation represented by the graph are 2 and 8. Thus, the factors of this quadratic graph can be written as;

(x - 2) and (x - 8)

Now, one rule about graphing inequalities is that If the inequality symbol is ≤ or ≥ , then the region includes the parabola, so it should be graphed with a solid line.

Otherwise, if the inequality symbol is < or > , the parabola should be drawn with a dotted line to indicate that the region does not include its boundary.

Now, since the parabola is drawn with a dashed line, it means that the inequality sign will be  < or > .

Lastly, since the outside of the parabola is shaded, it means that the inequality will be less than. Thus, our inequality equation is;

y < (x - 2)(x - 8)

olga55 [171]

Answer:

w = x + 50

Step-by-step explanation:

The dog is 50 pounds. The person's weight is x. You are trying to find the total weight of the dog and person. Therefore, you need to combine the two values to get the total, making the equation w = x + 50, or x + 50 = w

Joel’s veterinarian tells him that he can give his dog 11 5/8 mg of Benadryl for relief of his dogs allergies. Joel’s dog weighs
Sav [38]

Step-by-step explanation:

Given that,

The dosage of Benadryl for Dog is 11\dfrac{5}{8}\ mg

Weight of Joel's Dog is 15\dfrac{1}{2}\ \text{pounds}

(a)  Benadryl dosage per pound for Joel’s dog is calculated as :

\dfrac{11\dfrac{5}{8}}{15\dfrac{1}{2}}=\dfrac{\dfrac{11\times 8+5}{8}}{\dfrac{15\times 2+1}{2}}\\\\=\dfrac{\dfrac{93}{8}}{\dfrac{31}{2}}\\\\=\dfrac{93}{8}\times \dfrac{2}{31}\\\\=0.75\ \text{dosage per pound}

(b) If the weight of the Dog is 12 pounds, it means

\dfrac{11\dfrac{5}{8}}{12}\ \text{dosage per pounds}\\\\=\dfrac{\dfrac{93}{8}}{12}\\\\=\dfrac{93}{8}\times \dfrac{1}{12}\\\\=0.968\ \text{dosage per pounds}

Therefore, this is the required solution.
