Determine the solution type for each equation if one solution determine the value for x
sdas [7]

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.

3c

3

=

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

If the equation of a function is y = x2 – 5, what is the output when the input is -1?
Nimfa-mama [501]
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 :)
