What are all simplified form of the equation 2(3x

uysha [10]

Answer:

15.5 seconds.

Step-by-step explanation:

From the time the driver activated the brakes until he stopped, he travelled 76 - 14 = 62 meters.

During this time the car slowed down from 8 m/s to 0 m/s.

Assuming the deceleration was constant during this time we can apply one of the equations of motion for constant acceleration:

s = (u + v)t / 2 where u = initial velocity, v = final velocity, s = distance and t = the time, so:-

62 = (8 + 0)t/ 2

62 = 8t/2

4t = 62

t = 15.5 seconds.

A veterinarian needs to know an animal's weight in kilograms if 20 lb is about 9 kg in a dog weighs 30 lb use a ratio table to f

Jobisdone [24]

Answer:

13.5 kgs.

Step-by-step explanation:

Here we have to find conversion factor of lbs into kg.

For this we use the given information.

Given that the weight of a dog is 20 lbs and also 9 kg.

Hence we have conversion factor as

20 lbs = 9 kg

Or 1 lb =9/20 = 0.45 kg.

Using this, we find the 30 lb converted into kg.

For 1 lb, equivalent kg = 0.45

Hence for 30 lbs equivalent kg= 30(0.45) = 13.5 kg.

Find the solution(s) to the system of equations. Select all that apply.

Drupady [299]

Answer:

The points (3, 0) and (0, -3) would be the two solutions.

Hence, options A and D are correct.

Step-by-step explanation:

We know that when the system of equations meets at a point on a coordinate plane, that point or points will be the required set of solutions.

The point where the system of equations meets is called the point of intersection.

If we closely observe, the graph indicates that the graph of two equations meets at the following two points:

at x = 3 and y = 0

at x = 0, y = -3

Therefore, the points (3, 0) and (0, -3) would be the two solutions.

Hence, options A and D are correct.

Find the slope of a line perpendicular to the line 3x – 2y = 5.

jenyasd209 [6]

Answer:

2/3

Step-by-step explanation:

to the the slope of the perpendicular line we must first find the slope of line given in the problem. To do this we must transform this equation into the slope intercept format

The slope intercept form of a liner equation is:

Y = mx + b

Where m is slope and b is the y - intercept value.

solving the equation in the problem for y produces :

3x - 3x + 2y = -3x - 5

0 + 2y = 3x - 5

2y = - 3x - 5

2y = -3x - 5

2 2

y = - 3 x - 5

2. 2

Therefore the slope of this line is m = - 3

2

the slope of perpendicular line is the negative inverse of the slope of the line we are given,or

- 1

m

so for our problem the slope of a perpendicular line is - - 2 = 2
