Lee pays $72 in advance on his account at the movie store. Every time he rents a movie, $4 is deducted from his account for ever

lapo4ka [179]

So it would be,
y = 72 - 4x
y is the total money that is left on the account and x isthe movies rented. after renting 4 movies it would be,

y = 72 - 4(4)
y = 72 - 16
y = 56

So there are $56 left in the account after renting 4 movies.

Help me slove this problem thank you

Answer:

<h3> $\boxed{ \bold{ \boxed{ \sf{22 \: units}}}}$ </h3>

Step-by-step explanation:

Let the points be A and B

A ( -8 , - 18 )⇒( x₁ , y₁ )

B ( 14 , -18 )⇒( x₂ , y₂)

Finding the distance between these two points

$\sf{ \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } }$

Plug the values

⇒ $\sf{ \sqrt{ {(14 - ( - 8)}^{2} + {( - 18 - ( - 18))}^{2} } }$

We know that, $\sf{( - ) \times ( - ) = ( + )}$

⇒ $\sf{ \sqrt{ {(14 + 8)}^{2} + {( - 18 + 18)}^{2} } }$

Calculate

⇒ $\sf{ \sqrt{ {22}^{2} + {0}^{2} } }$

Evaluate the power

⇒ $\sf{ \sqrt{484} }$

⇒ $\sf{{22} }$ units

Hope I helped !

Best regards!!

Break the numbers under the radical into perfect squares: $\sqrt{2^2*2^2*2*x^2*x^2*z}$ . Take the perfect squares out: you have two 2's, and 2 x's, on the outside of the radical with 2 and z leftover: $3*2*2*x*x*\sqrt{2*z}$ . Multiply everything together to get $12x^2\sqrt{2z}$ .
