7 times what equals 1?
Arturiano [62]
For this case, the first thing we must do is define a variable.
 We have then:
 x: unknown number
 Doing the multiplication we have:
 (7) (x) = 1&#10;
 From here, we clear the value of x.
 We have then:
 x =  \frac{1}{7} &#10;
 Therefore, we have:
 (7) ( \frac{1}{7} ) = 1&#10;
 Answer:
 
7 times 1/7 equals 1

Show that the equation 2x + 3 cos x + e ^ x = 0 has a root on the interval [- 1, 0]
ExtremeBDS [4]

If <em>x</em> = -1, you have

2(-1) + 3 cos(-1) + <em>e</em> ⁻¹ ≈ -0.0112136 < 0

and if <em>x</em> = 0, you have

2(0) + 3 cos(0) + <em>e</em> ⁰ = 4 > 0

The function <em>f(x)</em> = 2<em>x</em> + 3 cos(<em>x</em>) + <em>eˣ</em> is continuous over the real numbers, so the intermediate value theorem applies, and it says that there is some -1 < <em>c</em> < 0 such that <em>f(c)</em> = 0.
