Vesnalui [34]
It's a flat horizontal line so the slope is 0

Slope = rise/run = 0/run = 0

The "run" can be any number you want as long as it's not 0.

Please help, I keep getting bots. <br> Using front-end estimation, find a reasonable estimate of:
Aleks [24]

Answer:

Roughly 18,000

Step-by-step explanation:

When you need to do rough mental math, you can do something like 720 vs 25 or 30 which is pretty simple to do in your head.

If you are very proficient in mental math, you can do something like 720 * 25, which is harder, but if you know the tricks, you can do this quickly.

720 * 25

Multiply 25 by 7.

175

Add two zeros.

17,500

Multiply 25 by 2

50

Add a zero.

500.

17500 + 500 = 18000

A one-topping pizza costs $15.00. Each additional topping costs $1.25. Let x be the number of additional toppings. You have $20
pantera1 [17]
So,

Our total will be equal to 20.  If we want 1 additional topping, we will have an additional $1.25.  <span>If we want 2 additional toppings, we will have an additional $2.50.  So we can just multiply the number of additional toppings by 1.25 to get the additional amount.

1.25x

However, you will have already spent $15.

1.25x + 15 = 20

This is option B.

P.S. You will be able to put exactly 4 additional toppings.</span>
