Y=1/4 x y=4x-5 parallel perpendicular neither

ziro4ka [17]

Answer:

Neither.

Step-by-step explanation:

The slope for the first one is 1/4 and the slope for the second one is 4. These are reciprocals, but not opposite reciprocals, meaning they are not perpendicular. An opposite reciprocal means the fraction is flipped (ex. 3/1 to 1/3) and the sign is changed. The line parallel to y=1/4x would be y= -4x.

A mountain trail is 12.1 miles long. If a hiker walks along the trail at a rate of 1.96 miles per hour, in approximately how man

snow_lady [41]

Given : A mountain path is 12.1 miles long.

a hiker walks along the path at a rate of 1.96 miles per hour

To Find: in approximate how many hours will the hiker walk the entre trail

Solution:

Distance = 12. 1 miles

Speed = 1.96 mile/hr

Distance = Speed * time

12.1 = 1.96 * t

=> t = 12.1/1.96

=> t = 6.17

=> t ≈ 6 hrs 10 mins

PLEASE HELP, THIS IS MY LAST QUESTION FOR THE YEAR SO I CAN PASS ALGEBRA (BRAINLIEST IF ANSWERED WITHIN 30 MINS AND CORRECT)

White raven [17]

Answer:

x intercepts: (-1,0) and (2.5,0)

It will be a minimum because the coeficcent for the degree is positive. The coordinates of the vertex are: (.75,-6.125)

To graph this I would first draw points on the vertex (.75,-6.125) and the x intercepts (-1,0) and (2.5,0). I would then simply just sketch a parabola that met all those points.

Step-by-step explanation:

A conjecture and the flowchart proof used to prove the conjecture are shown.

pishuonlain [190]

Answer:

∠1 is supplementary to ∠3.

Step-by-step explanation:

Given information: ABCD is a parallelogram.

Prove: ∠1 is supplementary to ∠3.

Proof:

∠1 = ∠ADB

∠2 = ∠DBC

∠3 = exterior angle adjacent to angle D B C.

Statement Reason

∠2 is supplementary to ∠3 Linear pairs

m∠2+m∠3=180° Definition of supplementary angles

$m\angle 1=m\angle 2$ Alternative interior angles

m∠1+m∠3=180° Substitute property of equality

∠1 is supplementary to ∠3 Definition of supplementary angles

Hence proved.
