Answer:
(5,-3) if the system is
y=x-8
2x+3y=1
Step-by-step explanation:
I think the system is to read:
y=x-8
2x+3y=1.
Please correct me if I'm wrong.
I'm going to plug 1st equation into 2nd equation giving me:
2x+3(x-8)=1 ->I replaced y with (x-8).
Distribute:
2x+3x-24=1
Combine like terms:
5x-24=1
Add 24 on both sides:
5x=25
Divide both sides by 5:
x=5
If y=x-8 and x=5, then y=5-8=-3.
The solution is (5,-3).
Answer:
(a-b-c)(a-b+c)
Step-by-step explanation:
a^2-2ab+b^2-c^2
(a-b)^2-c^2
(a-b-c)(a-b+c)
HEY THERE !!
AS WE KNOW A HEXAGON'S ALL ANGLES ARE 720°
SO HERE X = 720° - all rest angle's add
or 160+75+132+113+108= 588
x = 720 - 588
x = 132 °

Answer:
The level was 402.7ft. at the end of two weeks.
Step-by-step explanation:
First, we need to find the amount of decrease for the first week.
520 x 0.12 = 62.4
Now, we subtract the change for the first week.
520 - 62.4 = 457.6
Next, we find the change for the second week.
457.6 x 0.12 = 54.912
Then, we subtract the change for the second week.
457.6 - 54.912 = 402.688
And we are left with our final answer that is 402.688ft. or if you wish to round to the nearest tenth, then your answer would be 402.7ft.
Answer:
The equation rewritten in standard from --->
46x = 65.
solution --> x = 65/46
Alternate form --> x = 1 19/46, x = 1.41
