Step-by-step explanation:
1 .f(x)=
-x+1
f(-1)= (-1)-(-1)+1
f(-1)= 1+1+1
= 3
3.f(x)=-x+1
f( 1)=(1)-1+1
f( 1)=1-1+1
=1
5. f(x)=-x+1
f(3)=
-3+1
= 9-3+1
=7
2. g(x) = 5 - 3x
g( -8)=5-3(-8)
g( -8)=5+24
=29
4.g(x) = 5 - 3x
g(5)=5-3(5)
g(5)=5-15
=-10
6.g(x) = 5 - 3x
g(-3)=5-3(-3)
g(-3)=5+9
=14
Responda:
48,5
Explicação passo a passo:
Dado que:
Custo total de bolsa e sandália = 74,00
Deixei :
Custo da sandália = x
Custo da bolsa = x - 23
Preço da sandália:
x + (x - 23) = 74
x + x - 23 = 74
2x - 23 = 74
2x = 74 + 23
2x = 97
x = 97/2
x = 48,5
Portanto, custo da sandália, x = 48,5
Perimeter of a poligon= sum of all sides.
Perimeter of this triangle=s+(s+4)+3s=5s+4
An expression that represents the perimeter of this triangle is: 5s+4
In order to do mean you have to add all of the numbers in the list together. then divide them by the total amount of numbers (ex. 7,9,3,2,5. you would add all of these up 7+9+3+2+5=26 then you would divide that by 5 because there are five numbers in the list.
