Help help help if u can answer this I’ll mark u brainliest (6) (the one in the middle)
Hoochie [10]

You just have to plug in each thing:

So f(0):

3(0)^2 - 4 = -4

so its not A

f(-2) and f(2):

3(-2)^2 - 4

3(2)^2 -4

now we don't even have to calculate these, anything to the power of an even number is a positive number so -2^2 and 2^2 both equal 4

B is correct, so you can do the others if you want to check, but if B is true the others shouldn't be true.

At Lisa's printing Company LLC there are two kinds of printing presses model a witch can print 70 bucks per day and model B whic
erastovalidia [21]

Answer:

Model A is 9

Model B is 5

Step-by-step explanation:

At Lisa's printing Company LLC there are two kinds of printing presses model.

Let x = the number of model A printing press.

Let y = the number of the model B printing press.

model A can print 70 bucks per day and model B can print 55 bucks per day.

The total number of both models prints 905 bucks per day.

This means

70x + 55y = 905 - - - - - - - - -1

The company owns 14 total printing presses. This means

x + y = 14 - - - - - - - - - -2

x = 14-y

Put x = 14-y in equation 1

70(14-y) + 55y = 905

980 -70y + 55y = 905

-15y = 905-980= -75

y = -75 / -15= 5

x = 14-y = 14-5

= 9
