Tell whether the lines for this equation are parallel, perpendicular or neither

Mathematics
1 answer:
Arisa [49]3 years ago
8 0

Answer:

Perpendicular

Step-by-step explanation:

Parallel lines are lines which do not intersect and their equations have the same slope.

Perpendicular lines are lines which intersect at 90 degree angles and their equations have slopes which are the negative reciprocal of each other. If the slope is 2 then the negative reciprocal would be -1/2.

To determine which this pair of equations is compare their slopes from slope intercept form.

y= 7/3 x +3                                        12x + 28y = 40 becomes y = -3/7 x + 10/7

The slope is 7/3.                                The slope is -3/7.

These are negative reciprocals of each other. The lines are perpendicular,

In Springfield, a specific town in the US, 6 women and 25 men earned bachelor degrees in 2000. In 2010, however, 391 women and 4
Vladimir79 [104]

Answer:

  • See below

Step-by-step explanation:

For women, the initial number is 6, constant rate of change is w, number of years is x.

<u>Find the rate of change and work out the required formula:</u>

  • 10w + 6 = 391 ⇒ 10w = 385 ⇒ w = 38.5

<u>Formula:</u>

  • W(x) = 38.5x + 6

<u>Similarly for men, we get:</u>

  • 10m + 25 = 410 ⇒ 10m = 385 ⇒ m = 38.5

<u>Formula:</u>

  • M(x) = 38.5x + 25

What is the measure of angle TSU?
Irina-Kira [14]

Answer:

m<TSU = 65

Step-by-step explanation:

As one can see, the measure of angle (RST) is (90) degrees. This is indicated by the box around the angle. As a general rule, when there is a box around an angle, the angle measure if (90) degrees. It is also given that the measure of angle (RSU) is (25) degrees. As per the given diagram, the sum of the measures of angles (RSU) and (UST) is (RST). Therefore, one can form an equation and solve for the measure of angle (UST).

(RSU) + (UST) + (RST)

Substitute,

25 + (UST) = 90

Inverse operations,

25 + (UST) = 90

UST = 65

(<UST) is another way of naming angle (TSU).

100m world record was completed at an average speed of 37.6 km/h. work out this speed in meters per second?
pickupchik [31]

Step-by-step explanation:

1 km = 1000 m

1 hour = 3600 s

so,

37.6 km = 37,600 m (still per hour or per 3600 s).

in 1 second now that is

37600/3600 = 10.44444444... m/s
