What is coordinate?

Coordinate, is represented as the values on the x-axis and y-axis of the graph. while the coordinate x is called abscissa and the coordinate of the y is called ordinate.

Here,
To solve the system of equations using the substitution method, we substitute x = 9 into the first equation:

y = 3(9) - 4

y = 27 - 4

y = 23

Therefore, the solution of the system is (x, y) = (9, 23).

So, the correct answer is option D, (9, 23).

Escape what is on sale for 60% off the regular $80 price what is the sales price

Answers

Answer:

$32 is the sales price.

Step-by-step explanation:

First, change the percentage to a decimal.

60% = 60/100 = 0.6

Next, multiply 0.6 with the regular price ($80)

80 x 0.6 = 48

$48 is the discount. Subtract from the original price

80 - 48 = 32

$32 is the sales price.

~

Answer:

$32

Step-by-step explanation:

The sales price = original price - original price * discount rate

Factor out the original price

sales price = original price (1 -discount rate)

We know the original price is 80

We know the discount rate is 60% = .6

Substitute these values in

sales price = 80 (1-.6)

sales price = 80 * .4

sales price = 32

How to change feet to centimeters and feet centimeters to gallons

Answers

-- To change a length in feet to the same length in centimeters,
you can multiply the number by  30.48 .

-- There is no such unit as foot-centimeter, and if there were, I guess
it would have to be a unit of area, not volume, so there would be no way
to convert it to an equivalent number of gallons..
