Is the line through points p (3,-5) and Q(1,4)parallel to the line through points R( -1,1) and S (3,-3)
Anna [14]

Answer:

No

Step-by-step explanation:

To find out if the lines that go through the pairs of points are parallel, we must find the slope of each line. If the slopes are equivalent, then they are parallel. If not, then they are not parallel.

We can use the slope formula to find the slope between two points. The slope formula is:

m=\frac{y_2-y_1}{x_2-x_1}

where m is the slope between the points (x₁, y₁) and (x₂, y₂).

Lets first find the slope between points P and Q.

m=\frac{-5-4}{3-1}=\frac{-9}{2}=-4.5

So the slope between P and Q is -4.5.

Now lets find the slope between the points R and S.

m=\frac{-3-1}{3-(-1)}=\frac{-4}{4}=-1

So the slope between R and S is -1.

Since -4.5 does not equal -1, the lines are not parallel.

I hope you find my answer and explanation to be helpful. Happy studying.

Chloe is 5 feet 4 inches tall. There are 2.54 centimeters in 1 inch. What is Chloe’s height in centimeters?
Nikitich [7]
You need to make feet into inches
12×5=60
60+4=64

then divide 64 by 2.54 to get your answer and have it rounded to the tenths

64×2.54=25.2
Your answer rounded is 25.2cm

HELPP PLEASEEE ??? 2. The snow pack on Mt. Hood in the Oregon Cascades was 150 inches on
babunello [35]

Answer:

Therefore, the Forest Service will open trials on April 23rd.

Step-by-step explanation:

On January 15th, snow pack = 150 inches.

Snow pack decreases 11 inches per week.

The trials for hiking would be opened when the snow will be gone.

The snow will be gone in the number of weeks it takes to decease.

Number of weeks required = \frac{150}{11}

                                 = 13.64 weeks

Number of weeks required ≅ 14

Thus, it would take a maximum of 14 weeks for the snow to be gone from January 15th.

Therefore, the Forest Service will open trials on April 23rd.
