Can you mark as BREINLEST
Since the better deal is 9 for $8, start by dividing 77 by 9. You’ll get 8 with the remainder of 5. Answer is $69. AHHH I SEE WHAT YOU DID THERE!

line 2: y = -3x + 3
Step-by-step explanation:
you find the slope by using rise over run and then the y intercept
Answer:
x = 3
This triangle ABC will be a right triangle as its sides obey the Pythagoras theorem.
Step-by-step explanation:
Let us assume that the triangle Δ ABC has vertices A(x,3), B(-3,-1) and C(-1,-4) and it is a right triangle.
We have to determine x.
Applying the Pythagoras Theorem,
AB² + BC² = AC² {If AC is the hypotenuse of the right triangle}
⇒ [(x + 3)² + 4²] + [(- 2)² + 3²} = (x + 1)² + 7²
⇒ x² + 6x + 38 = x² + 2x + 50
⇒ 4x = 12
⇒ x = 3 (Answer)
