Order -6 1/4, -6.35, -6 1/5, and 6.1 from greatest to least. Explain.

1 answer:

3 0

If you turn all the numbers into decimals it becomes, -6.25, -6.35, -6.20, and, 6.1 so in order it would go 6.1, -6.20, -6.25, -6.35

A line of a slope of 8 passes through the point (-6,4). What is its equation in point slope form?

kotykmax [81]

Answer:

$\huge\boxed{y-4=8(x+6)}$

Step-by-step explanation:

The equation of a line in the point-slope form:

$y-y_1=m(x-x_1)$

$m-slope\\\\(x_1;\ y_1)-point$

We have:

$m=8\\\\(-6;\ 4)\to x_1=-6;\ y_1=4$

Substitute:

$y-4=8(x-(-6))\\\\y-4=8(x+6)$

Question

wlad13 [49]

Answer:

No Solutions

Step-by-step explanation:

First to complete the square, it will need to look something like

a^2+2ab+b^2

so in order to get that we can see that 4n^2+8n seems to be missing a piece.

a is the square root of 4n^2 which is 2n.

8n/2n=4

4/2=2

b=2

so now add 2 to both sides of the equation so now it's

4n^2+8n+4=-13

rewrite as (2n+2)^2=-13

Now you see a negative number as the result of a exponent.

A number squared will never be negative.

Therefore the answer is

No Solutions

A system of linear equations has been graphed in the diagram. Determine a reasonable solution for the system of equations.

zaharov [31]

Answer:

(- 2, 3)

Step-by-step explanation:

The solution of the graphed system is the point of intersection of the 2 lines.

This occurs in the second quadrant where the x- coordinate is negative and the y- coordinate positive.

A reasonable estimate is therefore (- 2, 3)

A collection of dimes and quarters has a total value of five dollars and contains 29 coins. How much of each kind of coin are th

Feliz [49]

Answer:

15 dimes and 14 quarters.

Step-by-step explanation:

Let q represent number of quarters and d represent number of dimes.

We have been given that a collection of dimes and quarters contains 29 coins. We can represent this information in an equation as:

$q+d=29...(1)$

$q=29-d...(1)$

We know each dime is worth $0.10 and each quarter is worth $0.25.

We are also told that the total value of coins is $5. We can represent this information in an equation as:

$0.25q+0.10d=5...(2)$

Upon substituting equation (1) in equation (2), we will get:

$0.25(29-d)+0.10d=5$

$7.25-0.25d+0.10d=5$

$7.25-0.15d=5$

$7.25-7.25-0.15d=5-7.25$

$-0.15d=-2.25$

$d=\frac{-2.25}{-0.15}$

$d=15$

Therefore, there are 15 dimes in the collection.

Upon substituting $d=15$ in equation (1), we will get:

$q=29-d\Rightarrow 29-15=14$

Therefore, there are 14 quarters in the collection.
