Two small pizzas with diameter 10 cost $15, while a large pizza with diameter of 16 cost $17 which pizza is less expensive per square inch

The larger pizza is less expensive per square inch

Step-by-step explanation:

we know that

The area of a circle (pizza) is equal to

step 1

Find the area of the smaller pizza

we have

----> the radius is half the diameter

substitute

Find the price per square unit

Remember that

The price of one smaller pizza is

so

step 2

Find the area of the larger pizza

we have

----> the radius is half the diameter

substitute

Find the price per square unit

so

Therefore

The larger pizza is less expensive per square inch

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
