14.75 is a rational number because it can be written in a ratio form \frac{x}{y} or x to y or x : y

14.75 = \frac{59}{4}

False, 14.75 is not an example of an irrational number.

False -

 An irrational number is a real number that can't be written as a simple fraction. So your EX, a rational number . ND Pi is a irrational number thats another example .

or


irrational numbrs cannot be written as a simple fraction like 34/73 or a/b . The number in decimal form, does not end because if it did it would end at one particular number, you could write it as that number over one, which would look like 0.6666666.. is rational cause it is equivalent too 2/3, Pi is irrational cause it cannot be represented by a simple fraction, we can approximate pi at 22/7, but 22/7 divide out doesn't end the whole pi .


The answer would be Falsee since 14.75 can be written as 14.75/1 or 1475/100 either way . REALLY HOPE THAT THIS HELPS BRO IF NOT COMMENT BELOWW PLX THANKS! BRO .

Choose the point-slope form of the equation of this line.​
igor_vitrenko [27]

Answer:

y= -5x +7

Step-by-step explanation:

We can see points on the graph:

  • (2, -3) and (3, -8)

The function in general form is:

  • y= mx+b

Let's find the slope and y-intercept as per identified points on the graph:

  • m= (y1-y1)/(x2-x1)
  • m= (-8+3)/(3-2)= -5

b= y- mx

  • b= - 3 -(-5)*2= -3 +10= 7

Based on the found values of m and b, the given line is:

  • y= -5x +7

Answer:

y = 5/2x

y = 35/2

Step-by-step explanation:

direct variation

y = kx

Substitute the values for x and y

15 = k(6)

Divide each side by 6 yo find k

15/6 = k

5/2 = k

The equation is y = 5/2 x

Now we know x =7

y = 5/2(7)

y = 35/2

Kennedy and Olivia go to the movie theater and purchase refreshments for their friends.
Anvisha [2.4K]

Answer:

6x + y = 38.75

x + 2y = 17

price of drink is $5.75

Step-by-step explanation:

Let the price  of popcorn be x

Let the price  of drink be y.

price  of  12 bags of popcorn will be 12x

price  of  2 drinks  will be 2y

it is given that "Kennedy spends a total of $77.50 on 12 bags of popcorn and 2 drinks."

thus

12x + 2y = 77.50

dividing LHS and RHS by 2 we have

12x/2 + 2y/2 = 77.50/2

=> 6x + y = 38.75 _________(1)

__________________________________________________

price  of  3 bags of popcorn will be 3x

price  of  6 drinks  will be 6y

it is given that "Olivia spends a total of $51.00 on 3 bags of popcorn and 6 drinks."

thus

3x + 6y = 51.00

dividing LHS and RHS by 3 we have

3x/3 + 6y/3 = 51/3

=> x + 2y = 17   _____________(2)

__________________________________________________

Thus we have two equation

6x + y = 38.75 _________(1)

x + 2y = 17

=> x = 17 - 2y

putting this value of x in equation 1 we have

6( 17 - 2y) + y = 38.75

=> 102 - 12y + y = 38.75

=> 102 - 11y = 38.75

=> -11y = 38.75 -102

=> -11y = -63.25

=> y = -63.25/-11 = 5.75

as we have x = 17 - 2y

using 5.75 in place of y

x = 17 - 2(5.75 )

=> x = 17 - 11.5

=> x = 5.5

Thus, system of equations are

6x + y = 38.75

x + 2y = 17

price of drink is $5.75
