Answer:

$4140

Step-by-step explanation:

You just need to find the difference between how much Michele has already and the amount she needs. The other information is just "trash"

So,

$5440 - $1300 = $4140

Can anyone help me with this question? <br>what is 6y+8x=24

Effectus [21]

so you will have to convert it to slope intercept form which is y=mx+B so you will have to isolate the y

6y+8x=24 subtract 8x to both sides

6y=-8x+24

divide 6 by both sides

y= -8/6x + 4

simplify

y= -4/3x + 4

the slope of the line is -4/3

Which graph shows a system of equations with no solutions?

podryga [215]

Graph of Parallel lines shows a system of equations with no solutions

Step-by-step explanation:

Consider a set of equations

$7x - 2y = 16\\21x + 6y =24$

If we solve this both equations using any one of the solving method, (Substitution method) then we will get

$7x-2y=16\\7x=16+2y\\x=\frac{16+2y}{7}$

substituting the following x in 2nd equation (21x + 6y = 24) We get

$21(\frac{16+2y}{7} )+6y=24\\3(16+2y)+6y=24\\48+6y+6y=24\\12y=24-48\\y=-\frac{24}{12} \\y=-2$

Put y= -2 in x equation

$x=\frac{16+2(-2)}{7}\\ x=\frac{16-4}{7}\\\x=\frac{12}{7} \\x=1.71$

Comparing these (x,y) values we can understand that they never meet at a point

I dont understand linear equations,what is the purpose of a linear equation?

Darina [25.2K]

A linear equation in two variables describes a relationship in which the value of one of the variables depends on the value of the other variable. In a linear equation in x and y, x is called x is the independent variable and y depends on it. We call y the dependent variable.

Please help me is this statement true or false 3(36 - 11) = 45?

viva [34]

Hi there! The answer is FALSE

To find the answer we need to work out the parenthesis.
$3(36 - 11) =$
$3 \times 36 - 3 \times 11 =$
$108 - 33 =$
$75$

75 does not equal 45 and therefore the statement is false.
