Answer:

Step-by-step explanation:

they are saying when -49 = -12x +47 what is x

so solve for x

-49-47 = -12x

-96 = -12x (b/c there are two negative signs they cancel out )

$\frac{96}{12}$ =x

8 = x

:) so when you input an 8 you get out a -49

Answer:

Number of students in vans =15 and bus =46

Step-by-step explanation:

use variables for the vans and buses

let x= vans and y=buses

Now solve the 2 equations simultaneously

remember to number your equations

6x+7y=412..........1

6x+9y=504.........2

make x the subject of one equation

and label it equation 3

6x=412—7y

$x = \frac{206}{3} - \frac{7y}{6} .............3$

subs 3 into 2

$6( \frac{206}{3} - \frac{7y}{6} ) + 9y = 504$

$412 - 7y + 9y = 504$

$- 7y + 9y = 504 - 412$

$2y = 92$

$y = 46...................4$

subs 4 into 1

$6x + 7(46) = 412$

$6x + 322 = 412$

$6x = 412 - 322$

$6x = 90$

$x = 15$

Therefore there are 15 students in each van and 46 students in each bus.

This figure shows y=f(x), the graph of the function f. If the function g is defined as g(x)= 2•f(x)-1, what is the value of g(1)

uranmaximum [27]

This is a nice twist to see if you can read the graph and interpret what it means.

f(1) is the y value of the graph when x = 1

So start at x = 1 and find the y value. Go straight up. The point you reach is (1,3)

so g(1) = 2*f(1) - 1

g(1) = 2*3 - 1

g(1) = 5

Answer

g(1) = 5
