It’s -1/3 because you subtract 1-5 and -3-9, you get -4/-12 then simplify to get -1/3.
The answer is A! This is because the formula is (x-h)^2 + (y-k)^2 = r^2.
Because there is no value, you can see that h and k are zero. This means that the center, (h,k) is (0,0).
Answer:
Step-by-step explanation:
i think its b or c
Y = mx + b where m = slope and b = <span>y-intercept
</span><span>slope of -3 and a y-intercept of -4
so
y = -3x - 4
answer
</span><span>D. y = -3x - 4</span>
Answer:
C. 162.5 sq ft.
Step-by-step explanation:
Given the following data;
S.A of smaller cylinder, S1 = 65 ft²
Ratio = 2:5 = 2 + 5 = 7
Let the total surface area be x.
S1 = 2/7 * x = 65
S1 = 2x = 65 * 7
S1 = 2x = 455
x = 455/2
x = 227.5 ft²
To find the surface area of the larger cylinder;
S2 = 5/7 * 227.5
S2 = 1137.5/7
S2 = 162.5 ft²
