Let the required no. be x then according to question
(84/100)*x = 21
x = 21*(100/84)
x = 2100/84
x = 25
hence the required no. is 25
hope it helped
hello :<span>
<span>an equation of the circle Center at the
A(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : a =0 and b = 0 (Center at the origin)
r = OP....p(-8,3)
r² = (OP)²
r² = (-8-0)² +(3-0)² = 64+9=73
an equation of the circle that satisfies the stated conditions.
Center at the origin, passing through P(-8, 3) is : x² +y² = 73</span></span>
Answer:
Step-by-step explanation:
A) Use the slope formula to find the slope m.
m=4/13
B) Use the point-slope formula, y−y1=m(x−x1) to find the equation of the line.
y=4/13x+198/13
C) Write in slope-intercept form, y=mx+b.
y=4/13x+198/13
