Answer:

Check to see if each input value is paired with only one output value. If so, the table represents a function.

Yes. It is a function.

Step-by-step explanation:

it’s not a function because the it is not a 1:2 ratio the way it started. so what that means is that the numbers follow the same pattern so it shows 1 to 2 then 2 to 5, the 5 would have to be a 4 for it to be a function

The answer would actually be A
F(x)=3x^2+4x
G(x)=2x^2-x+1
The two x^2 items are both positive and are added together to be 5x^2
The two x items would be added together to get 3x cause of the -x
Then +1 is just +1
Making the equation 5x^2+3x+1
If we were subtracting you would be absolutely correct, but since we are adding would go the opposite direction.

Answer: 5x^2+3x+1

Step-by-step explanation:

Add like terms

3x^2+2x^2=5x^2

4x+-x=3x

Answers

Answer:

x = -3.73 or -0.27

Step-by-step explanation:

From the question,

x²+ 4x+1 = 0

This is a quadratic equation, and it can be solved using any of the 3 methods.

Using completing the square method,

x²+4x = -1

Add half the coeffiecient of x, square it and add it to both side of the equation.

The coefficient of x is 4,

half the cofficient is 2

Add 2² to both side of the equation

x²+4x+2² = -1+2²

(x+2)² = 3

x+2 = ±√3

x+2 = ±1.73

Either,

x+2 = -1.73

x = -1.73-2

x = -3.73

or

x+2 = +1.73

x = =1.73-2

x = -0.27

After Selling 15 Lemonades, Jessica made 5 dollars. After selling 42 lemonades, she made 18.50

Answers

Answer:

y = 1/2x - 2.5

Step-by-step explanation:

(15, 5) and (42, 18.5)

Slope:

m=(y2-y1)/(x2-x1)

m=(18.5 - 5)/(42 - 15)

m = (13.5)/27

m = 1/2

y - y1 = m(x - x1)

y - 5 = 1/2(x - 15)

y - 5 = 1/2x - 7.5

y = 1/2x - 2.5

Answer:

2   or    1/2

Step-by-step explanation:

change in y over change in x

you didnt define what what x and what was y so ill provide both answers and you can figure which is correct

42-15/18.50-5   =27/13.5   =2

18.50-5/42-15    =13.5/27  =1/2

the answer is L < 5 .

tell whether the slope is positive or negative. then find the slope.​

Answers

Answer:

slope is negative

m=-1

Step-by-step explanation:

the slope of a line is positive if it passes through Quadrants III and I. The slope is negative if it passes through II and IV.

yes, this line passes through Quadrant I alongside II and IV, but it doesn't pass through Quadrant III (it has to pass through Quadrant III to be positive)

that means that the slope of this line must be negative

We can calculate the slope (m) with this formula:

(y2-y1)/(x2-x1)

we can pick two points- for example, (1,3) and (2,2)

label the points:

x1=1

y1=3

x2=2

y2=2

now substitute into the equation

m=(2-3)/(2-1)

m=-1/1

m=-1

the slope is -1

Hope this helps! :)
