How many solutions does the system of linear equations 6a + 3b = 12 and<br> 6a - 3b = 12 have?
Olin [163]

Answer:

One solution

Step-by-step explanation:

Lets solve it for b

3b= -6a+12

3b= 6a-12

Simplifying

b= -2a+4

b= 2a+4

Both have same slope and intercept hence both lines are going to intersect at one point. So the equations are having one solution.

Robin wants to find out the number of salamanders by a pond near her house. She catches 45 of them, puts a leg band on each sala
Verdich [7]
Given:
1st week: caught 45 salamanders and put leg bands on them
2nd week: caught 50 salamanders and 3 have leg bands

3/50 = 0.06 of the salamander population have leg bands.

45 / 0.06 = 750 total number of salamanders 

<span>45/750 = 0.06 or 6% </span>

The reasonable estimate of the number of salamanders by the pond is 750 salamanders.

Find the midpoint of the line segment connecting the two points (5,-3) (-4,7)
barxatty [35]

Answer:

The answer is

<h2>( \frac{1}{2}  \: , \: 2)</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

<h3>M  = ( \frac{x1 + x2}{2} ,  \:  \frac{y1 + y2}{2} )</h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(5,-3) and (-4,7)

The midpoint is

<h3>M  = ( \frac{5 - 4}{2} , \:  \frac{ - 3 + 7}{2} ) \\  = ( \frac{1}{2}  \: , \:  \frac{4}{2} )</h3>

We have the final answer as

<h3>( \frac{1}{2}  \: , \: 2)</h3>

Hope this helps you
