Ineed the answers because i honestly don’t know the answers . coordinate algebra is very hard and i need !

answer:

v = 4 volt

step-by-step explanation:

given: electrical power (w) p = 0.5 watt and resistance r ( ω ) r = 32 ohm

voltage v = ? (volt)

formula for calculating electrical power is:

p = v² / r => v² = p · r   => v ) √p · r = √0.5 · 32 = √16 = 4 volt

v = 4 volt

answer:

x= 6/5y+6/5

x= 2/3y+6

step-by-step explanation:

3x-18=2y

step 1: add 18 to both sides.

3x−18+18=2y+18

3x=2y+18

step 2: divide both sides by 3.

3x/3= 2y+18/3

x= 2/3y+6

#2

5x−6y=6

step 1: add 6y to both sides.

5x−6y+6y=6+6y

5x=6y+6

step 2: divide both sides by 5.

5x/5= 6y+6/5

x= 6/5y+6/5

answer:

9

step-by-step explanation:

the first thing to do is to subtract 16 from both side of the equation:

16 - 16 - b = 7 - 16

the 16s on the left cancel out resulting in:

-b = -9

think of the -b as -1(9). this is multiplication. by doing the inverse operation (division) we can get rid of the negative on the b. we will divide both sides by -1.

this leaves a positive b. since both parts of the right side of the equation are negative it becomes positive ( a negative divided by a negative is a positive).

the final answer is b= 9.

check our work by plugging in the b value (9) into the original equation:

16 - 9 = 7

7 = 7 is true so we now we have the right answer.
