Answer:
9^2= (x+2)^2+(y+8)^2
Step-by-step explanation:
The equation is r^2=(x+h)^2+(y-k)^2
Answer:
72.22
Step-by-step explanation:
Do you mean what percent is 35 of 50? I can help with that. Well since a percent is out of 100 you can multiply 50 by 2 to get to 100. But then you would also have to multiply 35 by 2. This will get you 70 out of 100. Which would make it 70 percent. Both number are proportionate so 70 would be your answer. But since this doesn't work for most others another way to solve it is to divide 35 by 50. And you get 0.7 Which it seventy-tenths of one hundred. Or 70 percent. So you could work this one both ways. But your final answer would be 70% no matter which you do.
Answer:
y = 9 x= -11
Step-by-step explanation:
opposite angles of a trapezoid are supplementary.
The two angles of the same base in an isosceles triangle are congruent.
-6x-16 = 50
-6x = 66
x= -11
The supplementary of 50 is 130
3x+16y+19 = 130
-33 +16y +19 = 130
16y = 144
y = 9
The sum of all 4 angles is 360 degrees
Answer: x = 1, y = -7
Step-by-step explanation:
Then substitute y=-7 in -4x=y+3
Order: (1,-7)
