Answer:
The answer is 53 or Square Root (sqrt) of 2809
Step-by-step explanation:
a^2+b^2=c^2
28^2+45^2=c^2
784+2025=c^2
c^2=sqrt 2809
c = 53
A. The (x,y) coordinates where the equations y =4x and y = 2x - 1 intersect on a graph is the solution to that system of equations. When solving for this system of equations by substitution of y, the equation 4x = 2x -1 is obtained. So the x-coordinate obtained is both a solution to the equation 4x = 2x - 1 and the intersection point of the system of equations y = 4x and y = 2x - 1.
B. Idk about this part... Says to make a tables to solve for 4x = 2x - 1.
If you make a table for Eq. #1. y = 4x and Eq. #2. y = 2x -1 maybe..
#1. y = 4x
x ...... y
-4 .. -16
-3 .. -12
-2 .. -8
-1 .. -4
0 ... 0
1 ... 4
2 .... 8
3 ... 12
4 ... 16
the solution to 4x = 2x - 1 ; the x-coordinate is not an integer value so Idk what the point of this is.....
4x = 2x - 1
4x - 2x = -1
2x = -1
x = -1/2
not an integer..
C. You can solve the equation 4x = 2x - 1 graphically by graphing y = 4x and y = 2x - 1 and identifying the x-coordinate at the point of intersection.
Answer:
Step-by-step explanation:
i)
A) For triangles, the sum of all the angles is equal to 180 degrees.
b) A quick Google search on "types of quadrilaterals" should be sufficient!
c) For quadrilaterals, the sum of all angles is equal to 360 degrees.
I'm sure you can figure out the answers from there.
The answer to your question is 3.6
