Answer:
Step-by-step explanation:
n = 3 => f(n) = -4*-3+8 = -44
n= 0 => f(n) = -4*0+8 = 8
n= 2 => f(n) = -4*2+8 = 0
n= 7 => f(n) = -4*7+8 = -20
Step-by-step explanation:
Vamos resolver sua equação passo a passo.
10-7c=10+2(3-5c)
Etapa 1: simplifique os dois lados da equação.
10-7c=10+2(3-5c)
10+-7c=10+(2)(3)+(2)(-5c)(Distribuir)
10+-7c=10+6+-10c
-7c+10=(-10c)+(10+6)(Combine os termos semelhantes)
-7c+10=-10c+16
-7c+10=-10c+16
Etapa 2: adicione 10c a ambos os lados.
-7c+10+10c=-10c+16+10c
3c+10=16
Etapa 3: subtraia 10 de ambos os lados.
3c+10-10=16-10
3c=6
Etapa 4: divida os dois lados por três.

Answer:
Number of vans = 7 students
Number of buses = 60 students
Step-by-step explanation:
Let
Number of vans = x
Number of buses = y
2x + 11y = 674 (1)
6x + 14y = 882 (2)
Multiply (1) by 3
6x + 33y = 2,022 (3)
6x + 14y = 882 (2)
Subtract (2) from (3)
33y - 14y = 2,022 - 882
19y = 1,140
y = 1,140 / 19
= 60
y = 60 students
Substitute y = 60 into
2x + 11y = 674 (1)
2x + 11(60) = 674
2x + 660 = 674
2x = 674 - 660
2x = 14
x = 14/2
= 7
x = 7 students
The input is the y
y = x^2 - 5
plug in what we're given
-1 = x^2 -5
add 5 to both sides
4 = x^2
take the square root of both sides
2 = x
Hope this helps :)
