Answer:

<u><em>x = -68/7 </em></u>          (-9.71428571429)

Step-by-step explanation:

Solve for x

-18 - 16 = 7x+ 34

- 18 - 16 - 34 = 7x

-68 = 7x

x = -68/7

----------------------

check

-18 - 16 = 7 * (-68/7) + 34

-18 - 16 - 34 = -68

-68 = -68

the answer is good

X-18-16 = 7x + 34

Simplify:

X -34 = 7x + 34

Add 34 to both sides:

X = 7x + 68

Subtract 7x from both sides:

-6x = 68

Divide both sides by-6

X = -34/3 = -11 1/3

Please answer the question .
Vsevolod [243]

Answer:

The answer is A.

Step-by-step explanation:

I'm very sorry if this is wrong but A would make the most sense. the formula y=mx+b. m is the slope, and b is the y-intercept so A is the most reasonable.

If this helped you I would appreciate it if you marked me Brainliest. Thank you and have a nice day!

Find the equation of the line that passes through the point (−3, −4) and is parallel to the line that passes through the points
Dimas [21]

Answer:

y = -\frac{1}{3}x - 5

Step-by-step explanation:

To write the equation of a line use the point slope formula y - y_1 = m(x-x_1). Find m by using the slope formula with the points.

m = \frac{y_2-y_1}{x_2-x_1} = \frac{1--3}{-5-7} =\frac{4}{-12} =-\frac{1}{3}

Since the line is parallel, it will have the same slope.

Substitute m = -1/3 and (-3,-4).

y --4 = -\frac{1}{3}(x --3)\\y + 4 = -\frac{1}{3}(x+3)\\y +4 = -\frac{1}{3}x - 1\\y = -\frac{1}{3}x - 5

What is the square root of 95.54
vladimir2022 [97]
Well this is simple a calculator type problem...but if you are curious as the the algorithm used by simple calculators and such...

They use a Newtonian approximation until it surpasses the precision level of the calculator or computer program..

A newtonian approximation is an interative process that gets closer and closer to the actual answer to any mathematical problem...it is of the form:

x-(f(x)/(df/dx))

In a square root problem you wish to know:

x=√n  where x is the root and n is the number

x^2=n

x^2-n=0

So f(x)=x^2-n and df/dx=2x so using the definition of the newton approximation you have:

x-((x^2-n)/(2x)) which simplifies further to:

(2x^2-x^2+n)/(2x)

(x^2+n)/(2x), where you can choose any starting value of x that you desire (though convergence to an exact (if possible) solution will be swifter the closer xi is to the actual value x)

In this case the number, n=95.54, so a decent starting value for x would be 10.

Using this initial x in (x^2+95.54)/(2x) will result in the following iterative sequence of x.

10, 9.777, 9.774457, 9.7744565, 9.7744565066299210578124802523397

The calculator result for my calc is: 9.7744565066299210578124802523381

So you see how accurate the newton method is in just a few iterations. :P
