Tanner is ordering a pizza at a restaurant. The cost of a cheese pizza is $8.69, and then it costs $0.30 for each additional top

Grace [21]

Answer:

Option A. $c=8.69+0.30t$

Step-by-step explanation:

Let

t ------> the number of additional toppings

c ----> the cost of the pizza in dollars

we know that

The linear equation that represent this situation is

$c=0.30t+8.69$

This is the equation of the line in slope intercept form

where

the slope m is equal to

$m=0.30\frac{\$}{topping}$

the y-intercept b is equal to

$b=\$8.69$ -----> the cost of a pizza without topping

Will give brainliest to the first person who answers

Answer:

z =86

Step-by-step explanation:

The exterior angle of a triangle is the sum of the opposite interior angles

z + z-39 = z+47

2z-39 = z+47

Subtract z from each side

z-39 = 47

Add 39 from each side

z = 47+39

z =86

Determine whether or not the given differential equation is separable, that is, whether it can be expressed in the form p(y) dy

Flura [38]

Answer:

Yes , it is separable

Step-by-step explanation:

We are given that DE

$\frac{dy}{dx}-2y=16+3xy+24x$

We have to find the the given DE is separable or not.

$\frac{dy}{dx}-2y=16x+3xy+24x$

$\frac{dy}{dx}=16+3xy+24x+2y$

$\frac{dy}{dx}=16+24x+3xy+2y=8(2+3x)+y(3x+2)$

$\frac{dy}{dx}=(2+3x)(8+y)$

$\frac{dy}{8+y}=(2+3x)dx$

When the DE is separable then it can be written as

$p(y)dy=q(x)dx$

Given DE is in Separable form.Therefore, it is separable.
