Answer:
(9, 6)
Step-by-step explanation:
add equations together: (x + y = 15) + (x - y = 3) --> x + x + y - y = 15 + 3 --> 2x = 18
isolate the variable: 2x/2 = 18/2 --> x = 9, so the x-coordinate is 9
substitute 9 in x's place in one of the equations: 9 + y = 15
solve for y: y = 15 - 9 --> y = 6, so the y-coordinate is 6
combine x and y coordinates together: (9, 6)
Uhh I wish I could help but I cannot I'm so sorry
Answer:
Hello!! the answer is undefined
Sin(x) = 0 where x = 0
Cos(x) = 1 where x = 0
Cot(0) is undefined
Answer:
The answer is B. It often helps to look at the desmos website to input the graphs.
Step-by-step explanation:
You can see that the points (4,13) intersect the graphs y = 2/5x+23 as well as be perpendicular to y=2/5x-5.
Answer:
V= 7,241.1
Step-by-step explanation:
V = 4/3 × π × r^3
V = 4/3 × 22/7 × 1,728
V = 88/21 × 1,728
V = 4.190 × 1,728
V= 7,241.1
