Answer:
R $ 3855
Step-by-step explanation:
João comprou uma TV por R $ 2400,00; um celular por R $ 1350,00 e um tênis por R $ 130,00 qual o valor total da compra?
O preço total de compra é calculado como:
Custo da TV + Custo do Celular + Custo do Tênis
R $ 2400,00 + R $ 1350,00 + R $ 130,00,
= R $ 3855

Answer:
D (4.34,3.22)
Step-by-step explanation:
Line Y (2,4), (-4,6)
**y=mx+b slope-intercept form
m=slope; b=y-intercept
plug in 1 point
Line Z (8,8) (-5,9)
Substitution
Answer: exactly one solution
Explanation: first we have to solve it. so in 2 + 6x = 3x + 3 we have to subtract 2 from both sides and we get 6x = 3x + 1. then, we subtract 3x from both sides and we get 3x = 1. we divide both sides by 3 and get x = 1/3, which is the only solution.
hope this helped!
