4 0

Answer:

30x + 5 < 120

30x < 20 - 5

30x < 15

x < 0.5

4x - 9 > 90

4x > 90+9

4x > 99

x = 24.75

28x + 4 < 140

28x < 140-4

28x < 136

x = 4/6/7

Aiden and Haisem are going to eat the same amount of hamburgers and fries, but from different restaurants. Aiden goes to Burger
Paha777 [63]

Answer:

the burgers be 3 and fries be 2

Step-by-step explanation:

The computation is shown below:

Let us assume burgers be x

And, the fries be y

Now according to the questiojn

1.25x + 0.50y = $4.75

1.50x + 0.99y = $6.48

Now multiply by 1.2 in the first equation

1.50x + 0.6y = $5.70

1.50x + 0.99y = $6.48

-0.39y = -0.78

y = 2

Now put the value of y in any of the above equation

1.25x + 0.50(2) = $4.75

x = 3

Hence, the burgers be 3 and fries be 2

If f(1) = 2 – 2 anid 9(37)<br> and g(x) = x2 – 9, what is the domain of g(x) = f(x)?
lana66690 [7]

Answer:

B

Step-by-step explanation:

Let divide g(x) by f(x)

\frac{ {x}^{2} - 9 }{2 - x {}^{ \frac{1}{2} } }

The domain of a rational function cannot equal zero so let set the bottom function to zero.

2 - x {}^{ \frac{1}{2} }  = 0

x  {}^{ \frac{1}{2} }  = 2

Square both sides

x = 4

Also we can simplify the bottom denomiator into a square root function

2 -  \sqrt{x}

The domain of a square root function is all real number greater than or equal to zero because a square root of a negative number isn't graphable.

So we must find a answer that

  • Disincludes 4 from the interval
  • Doesnt range in the negative number or infinity)
  • Range out in positve infinity
  • The answer to that is B
