Y=-3x+2 bc the line is going down so it’s negative and the y intercept is 2
Answer:
31
Step-by-step explanation:
5+(6-5)+5^2
use PEMDAS,
Parentheses
Exponents
Multiply
Divide
Addition
Subtraction
meaning-
5+(6-5)+5^2
5 + 1 + 5^2
5 + 1 + 25
31
Y = 2x + 1
y = x²+1
reemplazando
2x+1 = x²+1
ordenando
0=x²-2x
donde
0 = x (x-2)
resolviendo
0=x v x-2=0
0 =x x= 2
si x=0 entonces y = 1 par (0,1)
si x=2 entonces y= 5 par (2,5)
respuesta A
Option 1 : -22
using formula
(a + b )(a - b ) = a^2 - b^2
(√10 + 2√8) (√10 - 2√8)
= (√10)^2 - (2√8)^2
= 10 - 2×2×8=10-32
= -22
2nd question answer is option 3
