What's the answer for is substitution Y=-2 4x-3y=18

1 answer:

8 0

First you plug the y into the equation you are substituting it into, this gives you
4x-3(-2)=18
multiply the -3 by the -2 to get 4x+6=18
Subtract the 6 from both sides to get 4x=12
Finally divide by 4 to get x=3

<h3>Analysis of graph :-</h3>

We have given one graph which is plot between distance and time. where time is in minutes and distance is in seconds.

According to the graph

For the first 5 minute ( O to A) , The distance is continously increasing 2m / per minute .
For the 5 minute that is from 5 minute to 13 minute ( A to B) both marellize and her dog wally moving with the constant speed .
For next 3 minutes that is from 10 minutes to 13 minutes ( B to C) , The distance is continously decreasing with time .
For next 3 minutes that is from 13 to 16 minutes ( C to D) , Again they moved with constant speed .
For next 6 minute that is from 16 to 21 minutes ( D to E) . Again, There distance is increasing with time .
Again For next 4 minutes that is 21 to 25 minutes , they are moving with constant velocity .

<h3>Let's Begin :-</h3>

1) Between O and A

The marellize and wally when moving between O to A , The distance is constantly increasing with time.
The graph is Straight line

2) Between A and B

The marellize and wally when moving between A to B, The distance remains the same with time that is they moving with constant speed.
The graph is constant or steady

3) Between B to C

The marellize and wally when moving between B to C, The distance is constantly decreasing with time .
The graph is straight line but it follows decreasing function .

4) For covering the First 6 km ,

According to the graph,

For covering first 6 km, They took 3 minutes.

Find the value of x, 110°, 4x+2, and if you can help with steps that would be great :,)

Helen [10]

Answer:

x = 17

Step-by-step explanation:

The two angles with measures form a linear pair and are supplementary.

The measures of supplementary angles has a sum of 180°.

If you add the two given measures, the sum must equal 180°.

4x + 2 + 110 = 180

4x + 112 = 180

4x = 68

x = 68/4

x = 17
