Mya applied the distributive property to write the equivalent expressions below
45+ 72 - 9(5 + 9)
What is Mya's error?
Mya did not write the common factor in the correct place,
Mya wrote two expressions that are not equivalent
O Mya did not use the correct operations in the equation,
Mya used a factor that is not common to 45 and 72,

Answers

Answer:

Mya wrote two expressions that are not equivalent

Step-by-step explanation:

45 +72 does not equal to 9(5+9)

9(5+9) = 45 + 81

Answer:

Step-by-step explanation:

I dislike these kinds of questions. I could argue either of 2 answers - b and d.

b says that her error was that she wrote two expressions that are not equivalent and that is true. She did not write equivalent expressions.

d says she didn't use a common factor to both terms and that is true.

The actual answer is that she made a silly error which we all often do.

8 * 9 is 72

so the distributive property should be

9(5 + 8)

So, what's the answer? I would pick D, but hold your nose when you enter it.

What is the slope of the line parallel to 7x + 4y = -16?

Answers

Answer:

The slope of the line that is parallel to the given line is [tex]\frac{-7}{4}[/tex]

Step-by-step explanation:

Parallel lines have the same slopes and different y-intercepts

The slope of the line who has an equation ax + by = c is m = [tex]\frac{-a}{b}[/tex]

Let us use these rules to solve the question

∵ The equation of a given line is 7x + 4y = -16

→ Compare it with the form of the equation above

∴ a = 7 and b = 4

∵ The slope of the line = [tex]\frac{-a}{b}[/tex]

∴ The slope of the line = [tex]\frac{-7}{4}[/tex]

∵ Parallel lines have the same slope

∴ The slope of the line that is parallel to the given line is [tex]\frac{-7}{4}[/tex]

Graph the line with slope 1/4 and y intercept -2

Answers

Answer:

y= 1/4x -2

Step-by-step explanation:

Y=mx+b

m is the slope

b is the y intercept

The equation of line is y= 1/4x -2 .

What is slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given:

slope = 1/4 and y intercept = -2

Using slope- intercept form

y= mx + b

y= 1/4x + (-2)

y= 1/4x -2

Mario deposited $6,500 in a simple interest account that pays 2.8% interest annually. If Mario leaves the money in the account for 12 years, how much interest will he earn?

Answers

Answer:

$2,184

Step-by-step explanation:

Simple interest = (Principal × Rate × Time) / 100

Principal = $6,500

Rate = 2.8%

Time = 12 years

Simple interest = (Principal × Rate × Time) / 100

= (6,500 × 2.8 × 12) / 100

= 218,400 / 100

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - x + 7 ← is in slope- intercept form

with slope m = - 1

Write an expression for the perimeter of the triangle shown below:

A triangle is shown with side lengths labeled 2.3x plus 14, 2x, and negative 0.2x plus 15.

4.1x + 29

4.1x − 29

4.5x + 29

4.5x − 29

Answers

4.1x + 29 is the correct answer

Answer:The perimeter is just the sum of all the side lengths.So let's get to work and add it up: (2.3x + 14) + (2x) + (-0.2x + 15)Add up all the x's: (2.3x + 2x - 0.2x) = 4.1xAdd up all the ordinary numbers: (14 + 15) = 29So the perimeter is simply 4.1x + 29.
