Answer:

Angle 2 = Angle 4 = 76

Step-by-step explanation:

Here, we want to get the measures of angle 2 and angle 4

From what we have in the diagram, angle 2 and angle 5 are supplementary (meaning they add up to 180)

The reason for this is because both angles are same side interior angles

Thus,

angle 2 + angle 5 = 180

angle 2 = 180 - angle 5

angle 2 = 180 -104

angle 2 = 76

Furthermore, we can see that angle 2 equals angle 4 as they are vertically opposite angles

Thus, angle 2 = angle 4 = 76

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.
I hope this helps!

Answer: 5x^2+3x+1

Step-by-step explanation:

Solving for (f+g)(x) add both functions so

(3x^2+4x)+(2x^2-x+1)

Add like terms

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

4x+-x=3x

+1

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

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
