Answer:

x = \sqrt{1}

Step-by-step explanation:

(x + 6 )^2 = 49

get rid of the square , by square rooting the 49

x + 6 = \sqrt{49}

x = \sqrt{49} -6

x = \sqrt{1}

\sqrt{49} means + or - hence it could be -7 -6 = -1 ... or  7-6 = 1

therefore the answer is = or -  1

hence in terms of roots .. answer is :

\sqrt{1}

nadezda [96]

Answer:

  (-∞, -5/2) ∪ (1, ∞)

Step-by-step explanation:

"Increasing" means the graph goes up to the right. It is increasing from the left up to the local maximum--the peak at left.

It is increasing again from the local minimum on the right to the right side of the graph.

The two sections where the graph is increasing are ...

  (-∞, -5/2) ∪ (1, ∞)

__

The graph is <em>decreasing</em> between the maximum on the left and the minimum on the right.

HELLLPPPPPPP .... The probabilities of a test are represented by I for infected; U, uninfected; D, infection detected; and N, no
Dominik [7]

Answer:

P(I⋂D)

Step-by-step explanation:

The symbolic way to represent the probability of a true positive is P(I⋂D).

We know that I stands for Infected, U stands for Uninfected, D for Infection detected, N for infection no detected.

Then, a true positive will be given by the intersection of Infected and Infection Detected.

 x is the number of adults and y is the number of children.
   x + y = 12
<span>14x + 10y = 140
lets multiply the first equation by -10 and then add it to the second equation:
-10x - 10y = -120
</span>14x + 10y = <span>140
</span>-----------------------
4x + 0 = 20
x = 20/4
x = 5
then substitute in the original equation:
x + y = <span>12
</span>5 + y = <span>12
</span>y = 12 - 5
y = 7
therefore there were 5 adults and 7 children
