The <em>quadratic</em> equation has the following results: (p, q) = (8, 15), minimum point: (h, k) = (1, 4), range of values: - 4 < x < - 3

<h3>How to analyze quadratic equations</h3>

In this question we have a <em>quadratic</em> equation of the form y = x² + p · x + q , whose <em>missing</em> coefficients can be found by solving on the following system of <em>linear</em> equations:

- 5 · p + q = - 25

- 3 · p + q = - 9

(p, q) = (8, 15)

The vertex represents the <em>minimum</em> point, which is found by changing the form of the equation from <em>standard</em> form into <em>vertex</em> form:

y = x² + 8 · x + 15

y + 1 = x² + 8 · x + 16

y + 1 = (x + 4)²

(h, k) = (1, 4)

And lastly we must solve for x in the following inequality:

x² + 8 · x + 15 < x + 3

x² + 7 · x + 12 < 0

(x + 3) · (x + 4) < 0

- 4 < x < - 3

Solve: x³-7x²+36=0.​
Aliun [14]

Answer:

3,6,-2

Step-by-step explanation:

a+2a+b = 7

2a^2b = -36

a*2a + ab + 2ab = 0

or, a(2a+3b) = 0

so, b = -2a/3

Solve those and you find 3,6,-2

An integer is chosen between 0 and 100. What is the probability that it is divisible by 7?
IgorC [24]
Assuming 0 and 100 are included in the possible choices:

There are \left\lfloor\dfrac{101}7\right\rfloor=14 multiples of 7 between 0 and 100, so there is a \dfrac{14}{101}\approx0.1386 probability of choosing a multiple of 7.

pav-90 [236]
<h2>♪Answer : </h2>
  • f(x) = x + 20
  • g(x) = x + 5

»(f o g)(2)

  • find (f o g)(x)

»f(g(x))

»f(x + 5)

»x + 5 + 20

»x + 25

so, (f o g)(2) is

»2 + 25
