Answer:

no the quadrilateral isn't a parallelogram

Step-by-step explanation:

For it to be a parallelogram, the opposite sides must be parallel to each other and in this case it's not.

a line represented by y = 5x − 2 and a line perpendicular to it intersect at r(1, 3). what is the equation of the perpendicular

Snezhnost [94]

Y=ax+b, y=cx+d (a≠0, c≠0)
If the two line cross perpendicularly ⇔ ac= -1

So a tangent of the perpendicular line is "-(1/5)".

Then, the equation of the perpendicular line is y=-(1/5)x+a (a is <span> y-intercept</span>).

On the other hand, this equation pass r(1, 3), so

3 = -(1/5) times 1 + a

∴ a=16 / 5

Therefore, y=-(1/5)x+16 /5 is answer.

By the way, I'm Japanese so if you find some mistakes in my English, please let me know.

Evaluate,

kirill [66]

With 10 to the power to a negative number, it's easier.
Here's a trick: The negative number is the places to the right of the decimal. The last number is a 1, while the rest are 0s.

From this, we get: $10^{-4}=\boxed{0.0001}$

A snail travels 10 cm in 4 minutes at this rate how long will it take the snail to travel 24 cm? If you have the answer please l

Strike441 [17]

10/4 is 2.5. The snail travels 2.5 cms ever min. So 24/2.5 is 9.6 so the snail takes 9 mins and 36 seconds.

Students are given 3 minutes to complete each multiple-choice question on a test and 8 minutes for each free-response question.

Naddika [18.5K]

Answer:

x=16

Step-by-step explanation:

From the Free Response Row,

8(15-m)=x

For the Total Time(in minutes) column

3m+x=55
x=55-3m

Since x=55-3m and x=8(15-m)

Therefore:

55-3m =8(15-m)

55-3m=120-8m

Collect like terms

-3m+8m=120-55

5m=65

Divide both sides by 5

m=13

Therefore:

x=55-3m=55-3(13)=55-39

x=16
