Answer:

Step-by-step explanation:

alright, lets get started.

There are three triangles are given .

For 1 and 2 to be congruent, a triangle needs to be reflected. Means reflection is required.

For 1 and 3 to be congruent, a triangle needs to be reflected and rotated both, means reflection and rotation both are required.

For 2 and 3, triangle needs to be rotated only.

Means for triangle 2 and 3 to be congruent, it needs rotation.

So, the answer is 2 ans 3 option B : answer

Hope it will help :)

B...Triangles 2 and 3 are rotations of each other. Triangle 1 requires a reflection.

-4x+0y=-8
=> x=2
substitute 2 into either function for y
it will come out the same and u will have solution
Note, if slopes or coefficient of x are the same => no solution because lines are parallel

Whats the m.a.d. of 0, 3, 6, 9, 11, 13, 14? n=7

Answer:

4 2/7

Step-by-step explanation:

It is convenient to let a spreadsheet or graphing calculator do the tedious math for you. (See the attachment.)

_____

The sum of the numbers is 56, so their average is 56/7 = 8. Then the absolute deviations from average are ...

... 8, 5, 2, 1, 3, 5, 6

and the total of these is 30. The mean absolute deviation is this sum divided by the number of numbers, 7, so is ...

... 30/7 = 4 2/7

_____

More about Absolute Deviation from Average

"Absolute" here refers to the absolute value function, which drops the sign of a negative number. The absolute deviation of the data value 0 is ...

... |0 - 8| = |-8| = 8

For 3, it is ...

... |3 - 8| = |-5| = 5

Brian and his friends went to drive to the beach the beach is 80 miles away Brian drove at an average rate of 60 miles an hour h

Answer:

80 minutes or 1 hour 20 min

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

s -----> the speed in miles per hour

d ----> the distance in miles

t ----> he time in hours

$s=\frac{d}{t}$

solve for t

$t=\frac{d}{s}$

we have

$s=60\ mi/h$

$d=80\ mi$

substitute and solve for t

$t=\frac{80}{60}$

$t=\frac{4}{3}\ h$

Convert to minutes

$t=\frac{4}{3}(60)=80\ min$
