Answer:

x = -3

Step-by-step explanation:

3x - 7 = -16

3x - 7 + 7 = -16 + 7

3x = -9

x = -9/3

x = -3

3*-3  - 7 = -16

-9 -7 = -16

Subtract the given function and indicate the domain of the difference
maxonik [38]

Answer:

The domain is x\in (-\infty,\infty).

Step-by-step explanation:

Given functions f(x)=x^2+3x+1 and g(x)=2x^2-4x-1

Subtract these two functions:

f(x)-g(x)\\ \\=(x^2+3x+1)-(2x^2-4x-1)\\ \\=x^2+3x+1-2x^2+4x+1\\ \\=(x^2-2x^2)+(3x+4x)+(1+1)\\ \\=-x^2+7x+2

Plot these difference on the coordinate plane (see attached diagram). This function is defined for all vlues of x, so the domain is x\in (-\infty,\infty).

Before we can make the mashed potatoes, we need to boil some water. The water starts out at room temperature, 70° F, and increas
Karolina [17]

Answer:

Part a) y=50t+70

Part b) t=2.84\ min

Step-by-step explanation:

Part a) Create a linear equation

Let

t ----> the time in minutes

y ---> the temperature in °F

we know that

The linear equation in slope intercept form is equal to

y=mt+b

where

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value of the linear equation

In this problem we have

The slope m is equal to

m=50\° F\ per\ minute

The y-intercept is

b=70\° F

substitute

y=50t+70

Part b) How many minutes until the water boils at 212° F?

For y=212° F

substitute in the linear equation and solve for t

212=50t+70

50t=212-70

50t=142

t=2.84\ min
