Which Point Is A Reflection Of (1.5, -4.5) Across The X-axis And The Y-axis?A. Point IB. Point JC. Point

Answers

Answer 1

Answer:

(1.5, 4.5 ) and (- 1.5, - 4.5 )

Step-by-step explanation:

Under a reflection in the x- axis

a point (x, y ) → (x, - y ) , then

(1.5, - 4.5 ) → (1.5, 4.5 )

Under a reflection in the y- axis

a point (x, y ) → (- x, y ) , then

(1.5, - 4.5 ) → (- 1.5, - 4.5 )

If x- axis then y- axis

(1.5, - 4.5 ) → (1.5, 4.5 ) → (- 1.5, 4.5 )

Write an equation of the line that passes through 9,2 and is parallel to the line y=5/3x+9

Answers

Answer:

Equation: I believe its y=5/3x-13

Step-by-step explanation:

In the "y=5/3x+9" equation, 5/3 is the slope. You then take the slope (5/3) and the points (9,2) and add it to the equation "y+y1=m(x-x1)":

y-y1=m(x-x1)

distribute 5/3: y-2=5/3(x-9)

y-2=5/3x-45/3

y-2=5/3x-15

-add 2 on both sides-

y=5/3x-13

A jar is filled with quarters and nickels in the ratio 1 2/5 to 2 1/3. If there are 24 quarters in the jar, what is the ratio in dollar value of quarters to that of the nickels???

Answers

Answer:

  3 : 1

Step-by-step explanation:

The ratio of coins is ...

  1 2/5 : 2 1/3 = 7/5 : 7/3 = 3 : 5

The quarters have 5 times the dollar value of nickels, so the ratio of dollar values is ...

  5(3) : 5 = 3 : 1

The quarters have 3 times the dollar value of the nickels.

__

Additional comment

The number of nickels is 5/3 times the number of quarters, so is 5/3(24) = 40.

The dollar value of the quarters is 24($0.25) = $6.

The dollar value of the nickels is 40($0.05) = $2.

As above, the ratio of dollar values is 6:2 = 3 : 1.
