Answer:
(x +4)^2 +(y +8)^2 = 64
Step-by-step explanation:
The equation of a circle with center (h, k) and radius r is ...
(x -h)^2 +(y -k)^2 = r^2
The circle centered at (h, k) = (-4, -8) with radius 8 has equation ...
(x +4)^2 +(y +8)^2 = 64
Answer:
the answer is x=-25/56
Step-by-step explanation:
2 4/5x=-1 1/4
14/5x=-5/4
x=-25/56
Answer:
The length of the triangle is 22.
Step-by-step explanation:
Area = width*length
length = area/width = 198/9 = 22
Answer:
1.4 times k
Step-by-step explanation:
If k feet is the distance from home plate to third base, and the distance from first base to third base is 1.4 times the previous value, then
distance from first base to third base = 1.4 * k or 1.4 times k
If, for example, k=90 feet, then from first to third base there are
1.4*90=126 feet
<span>From the problem, you can get this equation:
Jane is 2 years older than Sally
J=z+2
David is 4 times older than Jane.
D=4J
</span>Write two equivalent expressions that represent David’s age in terms of Sally’s age, z, and explain how the two expressions relate to one another.<span>Sally is z years old.
From the 2 equation above, you can get:
</span>D=4J
D=4(z+2)
D=4z+8
D-8=4z
(D-8)/4=z
The two equivalent expression would be D=4z+8 and (D-8)/4=z
The expression that more usefull would be D=4z+8 if you want to determine David age.
