Answer:
x = 42.3.
Step-by-step explanation:
56.4 /14.4 = x / 10.8
Cross multiply:
14.4x = 56.4 * 10.8
x = (56.4 * 10.8) / 14.4
x = 42.3
Using theorem about secant segments we can write,
AB*AH=AG*AC
AC=4,
CG=6
AG=AC+CG=4+6=10
AH=3
AB= AH+HB=AH+x=3+x
(3+x)*3=10*4
9+3x=40
3x=40-9
3x=31
x=31/3≈10.3
HB≈10.3
EG=HB/2 (as radius and diameter)
EG=10.3/2≈5.2
Answer:
y+21 = -4(x-7)
Step-by-step explanation:
well first you need to find slope what is y2-y1 over x2-x1
23-(-21) ----> 23+21 = 44
-4 - 7 ---> -4 + -7 = -11
so it 44/-11 = -4 is the slope
now choose one pair of points like 7 , -21 and plug them in
y-y1 = m(slope)(x-x1)
so it be y+21 = -4(x-7)
also remember two negatives = a postitive
