The roots of the function f(x) = x2 – 2x – 3 are shown. what is the missing number? x = –1 and x =

Answers

we have

f(x)=x^(2)-2x-3

Find the roots

Equate the function to zero

x^(2)-2x-3=0

Group terms that contain the same variable, and move the constant to the opposite side of the equation

x^(2)-2x=3

Complete the square. Remember to balance the equation by adding the same constants to each side.

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

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

Rewrite as perfect squares

(x-1)^(2)=4

Square root both sides

(x-1)=(+/-)2

x=1(+/-)2

x=1+2=3

x=1-2=-1

therefore

the answer is

x=3
x^2 -2x -3 = 0

(x-3)(x+1)=0

x+1=0
x=-1

x-3=0
x = 3 

so the missing number is 3

Charlie has 298/440 points in Math class. What is his grade as a percentage?

Answers

(298).(100)/(440) = 67.727272....
So the answer is about 68%
All you have to do for this is divide the two numbers then round

298 / 440 = 0.67727272727273

So, if you round you would get 68%
Hope this helps!

Write the equation of the line that passes through the point(0, 2) and has a slope of
0

Answers

Answer:  y = 2

Step-by-step explanation:

When a line has a slope of 0, it is a horizontal line ( y = some value )

Since the line passes through the point (0, 2), then the line is y = 2

Which three-dimensional shapes do not have identical cross sections when cut by planes that are parallel to the base? cone
rectangular pyramid
cylinder
triangular prism

Answers

Answer:

Rectangular pyramid

Step-by-step explanation:

The three dimensional shapes can be cut through planes perpendicular or parallel to the base.

Here, the shapes are being cut parallel to the base.

Since, cone cylinder and triangular prism are identical when cut by planes that are parallel to the base.

Rectangular pyramid do not have identical cross sections.  

Option (b) is correct.
your answer is rectangular pyramid

How do u solve 4(y-3)+9-3y

Answers

if you need to find the y, and the 
4(y-3)+9-3y=0, then
we use PEMDAS, parenthesis first
4y-12+9-3y=0
4y-3y-12+9=0 
y-3=0 add 3 on both sides
y=3
4(y-3)+9-3y=0 \n 4y-12+9-3y=0 \n y-3=0 \n y=3
