Answer:
y= -4x-6 is the required equation.
Step-by-step explanation:
Lets take (0,-6) and (1,-10)
now
slope = (y2-y1)/(x2-x1)
= ((-10+6)/(1-0)
= -4/1
so, m = -4
again
y=mx+c
or, -10=-4×1+c
or, -10 = -4+c
so, c = -6
now
y=mx+c
or, y = -4x-6
Consider the right angles triangle with hypotenuse 15 and leg 8 cm formed by drawing the diagonal.
The other leg (x) will be the other side of the rectangle and , by Pythagoras we have:-
15^2 = 8^2 + x^2
x^2 = 225 - 64
x^2 = 161
x = 12.69 cms
So the perimeter p = 2*8 + 2* 12.69
= 16 + 25.38
= 41.38 cms (answer)
1st: 6 • 6 (2/10) - 3
2nd: 6 • 6 + 5 - 3
3rd: 36 + 2
Answer: 38
If it is not correct, I am deeply sorry. Feel free to correct me if I am incorrect. Thank you!
Answer:
we know all angles are 90° in the rectangle
therefore, angle d = bdc+bda = 90
=> 31+bda = 90
=>angle bda= 59
