Mathematics
1 answer:
Delvig [45]4 years ago

Answer:

Let’s rewrite both expressions first

y=3/2x+3

-3x+2y=6

The first expression is already plotted on the graph, so we only need to work on the second one.

Let’s turn the second equation into slope-intercept form. We can later use this to graph.

-3x+2y=6

*add 3x on both sides*

-3x+2y=6
+3x +3x
__________
2y=3x+6

*divide each number by 2*

2y=3x+6

2y/2=3x/2+6/2

y=3/2x+3

Since this is the same equation as the one graphed, it means there are an infinite number of solutions. If one were to graph this, the points would be the same as the original.

Hope this helps comment below for more questions :)

Does anyone have the answers for the rest of this or know the answers ?
irga5000 [103]

Answer:

4.

a)  4x^4-4x^3-16x^2+16x

b)  4x^4-4x^3-16x^2+16x

5. Yes

Step-by-step explanation:

The distributive property is:

(a+b)(c+d)=ac+ad+bc+bd

It can be extended to a lot of terms as well.

We will use this to multiply both of the probelms shown.

4 a)

(4x^2-4x)(x^2-4)=(4x^2)(x^2)-(4)(4x^2)-(4x)(x^2)+(4x)(4)=4x^4-16x^2-4x^3+16x=4x^4-4x^3-16x^2+16x

The answer is 4x^4-4x^3-16x^2+16x

4 b)

(x^2+x-2)(4x^2-8x)=(x^2)(4x^2)-(8x)(x^2)+(x)(4x^2)-(8x)(x)-(2)(4x^2)+(2)(8x)=4x^4-8x^3+4x^3-8x^2-8x^2+16x=4x^4-4x^3-16x^2+16x

The answer is  4x^4-4x^3-16x^2+16x

5. Yes

A train is moving at an average speed of 180 m/s. how long will it take to reach the station. Both stations are 80 km apart?
Alexxandr [17]

1 km = 1000 meters.

Find total meters: 80 km x 1000 meters per km = 80,000 meters.

Divide total meters by the given speed:

80,000 meters / 180 m/s = 444.44 seconds.

1 minute = 60 seconds

444.44. Seconds / 60 seconds per minute = 7.41 minutes = 7 minutes 24.42 seconds

Total time = 7 minutes 24.42 seconds

Round as needed.
