Answer:
4 in
Step-by-step explanation:
The Pythagorean theorem tells you the square of the hypotenuse is equal to the sum of the squares of the other two sides. Solve this problem by writing that relationship using the given information, then solving the equation for the missing side.
__
5² = 3² + ?²
25 = 9 + ?² . . . . . simplify
16 = ?² . . . . . . . . . subtract 9
4 = ? . . . . . . . . . . . take the square root
The missing length is 4 inches.
Arjun should have divided both sides of the equation by 7 instead of multiplying.
M=y2-y1/x2-x1
m=-10-1/5+2
m=-11/7
Simple,
The Y inctercept.
To find the Y intercept we know x=0 because the graph crosses the y axis when x axis is 0 so.
Y=4x-2
Y=4(0)-2
Y=-2 y interecpt is -2
The x intercept.
To find the X intercept we know y=0 because the graph crosses the x axis when y axis is 0 so.
Y=4x-2
0=4x-2
2=4x
2/4 = x x intercept is 2/4 or 0.5
