Answer:

-7/2

Step-by-step explanation:

Use distributive property: a(b +c) = a*b +a*c

-2(y-1) = 9

y*(-2) - 1*(-2) = 9

-2y + 2 = 9 {Subtract 2 from each side}

-2y = 9 - 2

-2y = 7 {Divide each side by -2}

y = 7/-2

y = -7/2

Answer:

(2,-8)

Step-by-step explanation:

y have

y=3x-14

y=x-10

we can substitute y in the first equation with x-10

x-10=3x-14

solve for x

4=2x

x=2

Now that we know what x equals we can solve for y

3(2)-14

6-14

-8=y

U=F(r+B) solve for r

irina1246 [14]

<h2>The value of r = $\dfrac{U-FB}{F}$ </h2>

Step-by-step explanation:

We have,

U = F(r + B)

To find, the value of r = ?

∴ U = F(r + B)

Dividing both sides by F, we get

$\dfrac{U }{F}=\dfrac{F(r+B) }{F}$

⇒ $\dfrac{U }{F}$ = r + B

⇒ r + B = $\dfrac{U }{F}$

⇒ r = $\dfrac{U }{F}$ - B

⇒ r = $\dfrac{U-FB}{F}$

∴ The value of r = $\dfrac{U-FB}{F}$
