Answer:
option number a -4 and -9
Given:
Number calories in a 6-inch pizza = 640 calories
For the pizza of 6 inch

For the pizza of 12 inch

Number calories in a 6-inch pizza = 640 calories, therefore:

Substitute:

And solve for x:

Now, Estimate the number of calories in one slice of a 12 inch pizza:

Answer: 320 calories
Answer:
x=2
Step-by-step explanation:
use distributive property: x^2+2x-1=4
remove the -1 by adding 1 on both sides: x^2+2x=5
use the guadratic fromula: ax²+bx+c=0
plug in the equation x^2+2x-5=0
a,b and c are the coefficients to plug into the formula
a=1, b=2, c=-1
Finally, you will find that x=2
Answer:

Step-by-step explanation:
Given the expression
, to solve the expression, we need to write both scientific notation to the same power of 10.

The expression above becomes
. On taking the difference;

The final expression gives the right answer
The domain of G is 4 and the range of G is 9 (domain=x, range=y :))
