Answer:
C.b< 13
Step-by-step explanation:
3b-7<32
Add 7 to each side
3b-7+7<32+7
3b < 39
Divide each side by 3
3b< 39/3
b < 13
Answer:
(x -a)^2 + y^2 = 2a^2
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
Here r^2 is the square of the distance between the center and the point on the circle. That can be found using the distance formula:
d^2 = r^2 = (x2-x1)^2 +(y2 -y1)^2 = (0-a)^2 +(-a-0)^2 = 2a^2
Filling in the above formula with (h, k) = (a, 0) and r^2 = 2a^2, we find the equation to be ...
(x -a)^2 +y^2 = 2a^2
The correct answer is the first one
Answer:
y=1/3x+7
Step-by-step explanation:
1. The given equation is y=1/3x-6 and it has to be parallel passing through (-12,3), so you just plug in the x and y values into the equation y=mx+b with 1/3 as the slope since its parallel (meaning the slope is the same for both eqts)
2. 3=1/3(-12)+b
3. 3=-4+b
4. 7=b
5. So, the equation is y=1/3x+7
