Marty bought two value meal. He paid $4.99 for each one. How much did he spend in all?

Solve the system of equations below by graphing.

Katen [24]

(0.5, 1.3) is the correct answer

Step-by-step explanation:

Given equations are:

$y = 4x-0.8\ \ \ Eqn1\\2x+y-2.3=0\ \ \ Eqn2$

As we can see that the given equations are linear equations which are graphed as straight lines on graph. The solution of two equations is the point of their intersection on the graph.

We can plot the graph of both equations using any online or desktop graphing tool.

We have used "Desmos" online graphing calculator to plot the graph of two lines (Picture Attached)

We can see from the graph that the lines intersect at: (0.517, 1.267)

Rounding off both coordinates of point of intersection to nearest tenth we get

(0.5, 1.3)

Hence,

(0.5, 1.3) is the correct answer

A number cube with the numbers 1 through 6 is rolled. What is the probability of the number cube showing a 4 or a number less th

Sonja [21]

Answer:

Step-by-step explanation:

The probability is

P

(

A

)

=

1

3

Explanation:

To calculate the probability you have to count the number of all possible results

|

Ω

|

and the number of results that fulfill the given condition

|

A

|

.

In this case

Ω

=

{

1

,

2

,

3

,

4

,

5

,

6

}

Thereare 6 possible result of a dice toss. So

|

Ω

|

=

6

The given condition is "the result is divisible by

3

", so

A

=

{

3

,

6

}

- those are the only numbers divisible by

3

, so

|

A

|

=

2

.

Finally to calculate the probability we have to divide

|

A

|

by

|

Ω

|

.

P

(

A

)

=

|

A

|

Ω

|

=

2

6

=

1

3

Note The probability is never larger than

1

, so if you get such result then there must be a mistake in calculations.

grandymaker [24]

Answer:

$2h^2$

Step-by-step explanation:

=> $(10h^4+h^2)-(10h^4-h^2)$

=> $10h^4+h^2-10h^4+h^2$

=> $h^2+h^2$

=> $2h^2$
