Answer:

The equation is c=2n

The constant of proportionality is 2

$18 will buy 9 cups of coffee

Step-by-step explanation:

Cost c=2*n

where c is the number of cups

The constant of proportion is 2

If cost is $18, then

18 = 2n

n = 18/2

n = 9

$18 will purchase 9 cups of coffee

Help Please? Factor Completely: 2x2 − 32

yawa3891 [41]

Answer:

Option 4th is correct

$2 \cdot (x-4)(x+4)$

Step-by-step explanation:

Using difference of square:

$a^2-b^2=(a-b)(a+b)$

GCF is the largest number that divide the given polynomial or expression.

Given the expression:

$2x^2-32$

We have to completely factor the expression.

GCF of $2x^2$ and 32 is, 2

then;

$2 \cdot (x^2-16)$

Using difference of square

$2 \cdot (x-4)(x+4)$

therefore, the completely factor of $2x^2-32$ is, $2 \cdot (x-4)(x+4)$

4x + 5y = 10

EleoNora [17]

First leave y by itself. first subtract 4x by both sides. 5y=10-4x. then divide 5 by both sides y= 10-4x/5. y=5-4x/5. when graphing in sert the x into the equation to give you y.
