Schach [20]3 years ago

Answer:

x = \frac{-7}{3}

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

7x + 3 − x − 5 = −16

7x + 3 + − x + −5 = −16

(7x + −x) + (3 + −5) = −16(Combine Like Terms)

6x + −2 = −16

6x − 2 = −16

Step 2: Add 2 to both sides.

6x − 2 + 2 = −16 + 2

6x = −14

Step 3: Divide both sides by 6.

\frac{6x}{6} = \frac{-14}{6}

x = \frac{-7}{3}

Hope this helps!

Answer:

(7x+3)+(-x-5)=-16

or,7x+3-x-5=-16

or,6x-2=-16

or,6x=-16+2

or,6x=-14

or,x=-14/6

hence x=-14/6

A rocket is launched into the air. The height h(t), in yards, of the rocket is a function of time, t, in seconds, as shown in th
RideAnS [48]

Answer:

From 3 to 6 seconds, the rocket is falling 11 yards per second.

Step-by-step explanation:

Normal pace of progress is exactly the same thing as the slant. Since this is explanatory, we can't track down the specific pace of progress as we could if this were a straight capacity. Be that as it may, we can utilize a similar thought. At the point when t = 3, h(t) = 33, so the organize point is (3, 33). At the point when t = 6, h(t) = 0, so the facilitate is (6, 0). Attachment those qualities into the incline recipe:  

m= 0-33/6-3 and m=-33/3 which is 11  

From 3 to 6 seconds, the rocket is falling 11 yards each second.

What is obtained by squaring the standard deviation?
anastassius [24]
<h2>Answer:</h2>

Variance

<h2>Step-by-step explanation:</h2>

The standard deviation is related to the variance. The standard deviation measures the variation or dispersion of a set of data and is represented by the Greek letter sigma \sigma, while the variance measures how far a set of  numbers are spread out from their average value. The variance is obtained by squaring the standard deviation, so the variance can be found as \sigma^{2}
