Answer 1

Answer:

Answer:

7t^5 - t^3

6x -3 +2x/y

Step-by-step explanation:

A. (7t^8 - t^6)/t^3

Separate into 2 fractions

(7t^8/t^3) - (t^6)/t^3

Remember a^b / a^c = a^ (b-c)

7 t^(8-3) - t^(6-3)

7t^5 - t^3

B (12x^2y - 6xy +4x^2)/2xy

Separate into 3 fractions

12x^2y/2xy - 6xy/2xy +4x^2/2xy

Remember a^b / a^c = a^ (b-c)

12/2 x^(2-1) y^(1-1) - 6/2 x/x * y/y +4/2 x^(2-1) /y

6 x y^0 -3*1*1 +2 x/y

Remember that x^0 = 1

6x -3 +2x/y

Why might someone choose to use the the y-intercept and the slope to graph a line?

Answers

For this case the generic equation of the line is given by:

y = mx + b

Where,

m: slope of the line

b: intersection with the y axis.

To graph a line it is necessary to know the values of m and b.

Answer:

y = mx + b

You need to know m and b to graph the function completely.

For this reason, someone would choose to use the y-intercept and the slope

If someone had an equation that was in slope intercept form, the y intercept and slope are easily accessible and easily calculable.

Therefore, if someone had a line that was in slope intercept form, then they would probably choose to use the y intercept and slope to graph that line.

The formula d = ft can be used to calculate the distance (d) an object travels using its rate of speed (r) and the time it travels (t). Using the formula, which shows the rate the object traveled?

Answers

In that first sentence, you should have typed d = r * t
Rate would be calculated as:
rate = distance / time

Jerome bought screen for 59 cents per sq ft. how much did 12 sq ft cost

Answers

Answer:

$7.08

Step-by-step explanation:

59 cents = 1 sq ft

? = 12 sq ft

To get from the 1 to the 12 we multiply by 12, so we must do the same to the 59 cents.

0.59 * 12 = 7.08

Therefore, the cost of 12 sq ft is $7.08.
