Mathematics

Answer:

neither

Step-by-step explanation:

Parallel lines have equal slopes

The product of the slopes of perpendicular lines = - 1

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x - 9 ← is in slope- intercept form

with slope m = 2

y = \frac{1}{2} x + 3 ← is in slope- intercept form

with slope m = \frac{1}{2}

2 ≠ \frac{1}{2} , then lines are not parallel

2 × \frac{1}{2} = 1 ≠ - 1, then lines are not perpendicular

Answer:

perpendicular

Step-by-step explanation:

First of all

We'll find the slope (m) of y=2x-7

if I put x=0 then, y= —7

And if I put x=—1 then, y= —9

so, m= {—7-(—9)} /{0-(—1)}

m= (—7+9) / (0+1) = 2

Now we'll find the slope (n) of y= 1/2x —1

If I put x=1 then, y=—1/2

And if I put x= —1 then, y= —3/2

So, n= {—1/2 —(—3/2)} / {1-(—1)}

n= (—1/2 +3/2 ) / (1+1)

n= 1/2

So, slope (m) of y= 2x-7 and slope (n) of y= 1/2x —1

m × n = 2 × 1/2 = 1

The distances between three cities on a map are 45 miles, 56 miles, and 72 miles. Do the positions of
ollegr [7]

Answer:

The position of the three cities do not form a right-triangle.

Step-by-step explanation:

There are three cities on a map (say A, B, and C).

Now, the distances between them are 45 miles, 56 miles, and 72 miles.

i.e. AB= 45 miles, BC= 56 miles and CA =72 miles.

If the three cities A, B, C form a right-angled triangle on the map, then applying Pythagoras Theorem AB² +BC² =AC²

or, AC= √(AB² +BC²) must be satisfied.

Now, right-hand side of the above equation =√(45²+56²) =71.84 ≠ 72 (AC)

Hence, Right-hand side ≠ Left-hand side.

Therefore, the positions of the three cities do not form a right triangle. (Answer)

The graph of the piecewise function f(x) is shown.
NeTakaya

Answer:

{f(x) | -∞ < f(x) ≤ 4 }

Step-by-step explanation:

The range is made up of the y values.  Remember f(x) = y

In this graph the least value of y is -∞ and the greatest value of y is 4

So, the range is {f(x) | -∞ < f(x) ≤ 4 } which is the 2nd choice
