Answer:
5/4
Step-by-step explanation:
9a + 2b = 5a - 7b
Bringing like terms to one side of the equation,
9a - 5a = 7b - 2b
4a = 5b
By cross multiplication,
a/b = 5/4

Answer:
2^12/2^8 is equivalent to 512 otherwise can be written as 2^9
Answer:
29 ft
Step-by-step explanation:
the screens have 90 degree angles so they form right triangles with the diagonal, so use Pythagorean theorem to solve for the diagonal
diagonal² = 21² +20² , square and square root both sides of the equation
diagonal = √441+400, add
diagonal = √841, square root
diagonal = 29ft
There are multiple ways that you could graph this quadratic equation.
I would start by finding the vertex. The x-value in the vertex is found with -b/2a. The take you value and input back into the equation to find the y-value of your vertex.
Then, you could make a list of points on both sides of the vertex to create a table with which to create the parabola.
