Answer:
3
Step-by-step explanation:
The solution to a system of equations is the intersection point of two or more lines on a graph.
In this case, we see that at (1, 3)
Remember that this question is asking for the y intercept, not the full coordinates or the x intercept.
We know that the full coordinates are (1, 3), or (x, y), and since we need y, we know the y cooridnates are 3, not 1, since this is x.
So the first answer, A, is correct.
Hope this helps!
Answer:
125
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Use the formula for the SA of a hemisphere.

Now we can find the radius of the hemisphere, which is 15.
Then, we can square that and multiply it by 2 to get 450.
Now, let's use the formula for the Volume of a hemisphere.

Now we can cube 15 and multiply it by 2 to get 6750.
Then we can divide this number by 3.
2250.
So the answer is D.
Answer:
x = 323 in
Step-by-step explanation:
Given triangles are similar, so their corresponding sides would be in proportion:
3ft = 3*12 = 36 in
5ft 8 in = 5*12 + 8 = 68 in
14 ft 3 in = 14*12 + 3 = 171 in

Answer: d = 40 - 5/2t; 1995
