Answer:
(1,5)
Step-by-step explanation:
y=3x+2
x+2y = 11
Substitute the whole value of y to the second equation:
x+ 2 (3x +2)=11
Distribute 2
x+6x+4=11
Combine like terms:
7x=7
x=1
Plug in the x value to any equation:
y=3(1)+2
y=3+2
y=5
Answer:
The answer is 27.5 I think-
Answer:
37.6
Step-by-step explanation:
i got it right thank meh
Lets look at it as the Pythagorean theorem, so A²+B²=C²
First step: find the X (a) and the Y (b)
|6-0| = 6
|-4-2|= 6
Second step: 6²+6²=c²
36+36=C²
72=C²
√72=√C²
8.49=C
your final answer would be 8.49 units
V (cone) = (1÷3) × (r×r×h) л cm3
3 cone = 1 cylinder (if "h" and "r" is same)
There is two cone...
1st one: (1÷3) × 3×3×5 л cm3 = 15л cm3
2nd one: (1÷3) × 3×3×8 л cm3 = 24л cm3
15 + 24 = 39л cm3
