Make y the subject of these equations.<br> by² = d<br> Jay = 6<br> ay - cy = d.<br> cy - b) = y
allsm [11]

Answer:

See all the answers  below.

Step-by-step explanation:

by² = d

Jay = 6

ay - cy = d.

cy - b) = y

Option A

by² = d

divide both side by b

y² = d/b

square both sides

y=√d/b

Option B

Jay = 6

Divide both sides by Ja

y= 6/Ja

Option C

ay - cy = d

y(a-c)=d

divide both sides by (a-c)

y= d/(a-c)

Option D

(cy - b) = y

y-cy=-b

y(1-c)=-b

y= -b/(1-c)

Alborosie
X, y - the numbers

The numbers add to 9 and multiply to -70.
x+y=9 \\&#10;xy=-70 \\ \\&#10;y=9-x \\&#10;xy=-70 \\ \\&#10;\hbox{substitute 9-x for y in the second equation:} \\&#10;x(9-x)=-70 \\&#10;9x-x^2=-70 \\&#10;-x^2+9x+70=0 \\&#10;-x^2+14x-5x+70=0 \\&#10;-x(x-14)-5(x-14)=0 \\&#10;(-x-5)(x-14)=0 \\&#10;-x-5=0 \ \lor \ x-14=0 \\&#10;x=-5 \ \lor \ x=14 \\ \\&#10;y=9-x \\&#10;y=9-(-5) \ \lor \ y=9-14 \\&#10;y=14 \ \lor \ y=-5 \\ \\&#10;(x,y)=(-5,14) \hbox{ or } (x,y)=(14,-5)

The numbers are -5 and 14.

Please help this is the last problem I need
tangare [24]

Answer:

sin 54 = \frac{x}{14}

Step-by-step explanation:

sine = \frac{opposite}{hypotenuse}

Side z is the adjacent, since it is next to the angle you are solving for.

Side x is the opposite, since it is opposite the angle you are solving for.

The side measuring 14 is the hypotenuse, since it is across from the right angle.

sin 54 = \frac{x}{14}
