Hope this helps

- Que

Answer:

B. 2x + 3 = 4

Step-by-step explanation:

6x + 9 = 12

Find this out by solving for x start with subtraction property of equality.

6x = 3

Division property of equality

x = 3/6 or x = 0.5

_____________________

Now insert the value of x to check other answers starting with A

0.5 + 9 = 6

<em>9.5 = 6 is incorrect so not A.</em>

Now B

2(0.5) + 3 = 4

1 + 3 = 4

4 = 4 is correct so B is your answer

Now C

3(0.5) + 9 = 6

1.5 + 9 = 6

<em>10.5 = 6 is incorrect so not C</em>

Lastly D

6(0.5) + 12 = 9

3 + 12 = 9

<em>15 = 9 is incorrect so not D either. </em>

Answer:

B

Step-by-step explanation:

if we divide both sides of 6x + 9 = 12 by 3

(6x + 9)/3 = 12/3

2x + 3 = 4 ---> which matches choice B

Through: (-3,-5), parallel to y = 2x + 2​
Archy [21]

Answer:

y = 2x + 1

Step-by-step explanation:

Since you have an equation and a point, all you need to do is substitute the coordinates into the equation and then solve for the y-intercept (or "b"):

y = mx + b

y = 2x + 2

(-3, -5)

-5 = 2(-3) + b

-5 = -6 + b

-5 + 6 = b

b = 1

Now you have your final equation:

y = 2x + 1

*Remember that parallel lines have the same slope, so finding a new slope is not needed!

Give a big-o estimate for the number of operations (where an operation is an addition or a multiplication) used in this segment
Marianna [84]
We have a "rectangular" double loop, meaning that both loops go to completion.
So there are 3*4=12 executions of t:=t+ij.

Assuming two operatiions per execution of the innermost loop, (i.e. ignoring the implied additions in increment of subscripts), we have 12*2=24 operations in all.

Here the number of operations (+ or *) is exactly known (=24). 

Big-O estimates are used for cases with a varying scale of operations, governed by a variable (usually n) to indicate the sensitivity of the number of operations relative to a change in the size of n.

Here we do not have a scale, nor n is defined.  The number of operations is constant and known at 24.   So a variable is required to find the big-O estimate.

To speed the process of surveying, surveyors use brass metal plates to record important information. The benchmarks, as they are
Agata [3.3K]

Answer:

Feet Above Sea Level

Step-by-step explanation:

A benchmark is a term in Surveying and Geo informatics, that describes a point of reference established at a known elevation which serves as basis in which other elevation or topographical point can be measured.

Therefore, when determining the benchmark, it's height is calculated relative to the vertical datum of the area, typically mean sea level, which is then recorded in FEET ABOVE SEA LEVEL.

Hence, Benchmarks measurements refer to FEET ABOVE SEA LEVEL.
