Find the line for each given equation in the problem.

If they cross each other ( at least one solution) it is consistent.

If they do not cross each other at all, it is inconsistent.

If a consistent system has only one answer it would be independent.

If a consistent system has infinite solutions ( this would be just a straight line) it would be dependent.

If there are no solutions, it is neither dependent or independent.

1. Both lines cross each other in one place, so this is consistent and independent.

2. Both lines cross each other in one place, so this is consistent and independent.

3. The two lines do not cross each other, so this is inconsistent.

There are no solutions, so this is neither dependent or independent.

4. Both lines cross each other in one place, so this is consistent and independent.

Explain how complex fractions can be used to solve problems involving ratios?

alisha [4.7K]

Complex fractions are numbers in which the numerator and the denominator are both fractions. in this case, to solve the ratio, we can multiply the numerator fraction by the reciprocal of the denominator fraction. Another way is to solve the fraction separately and then divide eventually.

Part I: Marco rented a small moving van. The moving company charges $40 a day for up to 5 days. The input is the time, in days,

Snezhnost [94]

Given mapping is a function.

Domain: $\{1,2,3,4,5\}$

Range: $\{40,80,120,160,200\}$

Step-by-step explanation:

By observing Marco's mapping diagram we can see that every value in time is mapped to only one value in the cost. This means that there will be no repetition or same output to two different outputs so given mapping is a function.

Domain:

Domain is the set of all inputs of a function. Here time is input so domain of function is:

$\{1,2,3,4,5\}$

Range:

Range is the set of all outputs of the function on domain so the range of the given function is:

$\{40,80,120,160,200\}$

Hence,

Given mapping is a function.

Domain: $\{1,2,3,4,5\}$

Range: $\{40,80,120,160,200\}$

Keywords: Domain, range, function

Mrrafil [7]

Answer:

x = 1

Step-by-step explanation:

${x}^{2 } - {x}^{2} - 3x + 3 \\ - 3x + 3 \\ 3x = 3 \\ x = 1$

How do you write an equation for the sum of three consecutive numbers equals 384?

emmasim [6.3K]

Let x be the smallest number.
x＋(x＋1)＋(x＋2)＝384
3x＋3＝384
3x＝381
x＝127
The three consecutive numbers are 127, 128 and 129.

Hope my answer helped u :)

the length of this prism is multiplied by a scale factor of 1/2 to create rectangular prism B the volume of rectangular prism B

anastassius [24]

We know that

[volume of rectangular prism]=L*W*h
L= 6 in prism A
volume of rectangular prism A=6*w*h

L=6*(1/2)------> L=3 in prism B

volume of rectangular prism B=3*w*h
so
volume of rectangular prism B=[volume of rectangular prism A]/2

the answer is
Volume of B is 1/2 volume of A
