Answer:
1=27
2=34
Step-by-step explanation:
1)9y power 2÷3
or, y=9 power 2÷3
or, y=9×9÷3
or, y=81÷3
or, y=27
2) (8x power 2+4x)÷2
=(8x×8+4x)÷2
=(64x+4x)÷2
=68x÷2
or, x=68÷2
or, x=34
Answer:
y = 1/3x - 1
Step-by-step explanation:
This is because the slope is rise over run. The slope is 1/3 and the y-intercept is -1
Hope this helps
Primeiro multiplica o -2 com tudo que tem dentro do parenteses (chuveirinho) -114 = -5x -2(4x+18)
-2 . 4x = -8x + -2 . 18 = -36 = -8x-36
Agora soma os números com incógnitas (no caso x)
-114 = - 5x - 8x -36
Joga a incógnita do outro, tornando positiva
-114 = -13x - 36
13x -114 = -36
e o 114 do outro lado, ficando positiva também
13x -114 = -36
13x = - 36 + 114
13x = 78
x = 78 /13
x= 6

Answer:
SLOPE = - 4
y-intercept = 9
Step-by-step explanation:
