Answer:
x=47, y=68
Step-by-step explanation:
Add the two equations. Then we get
-y=-68
y=68
Substituting the value of y in the first equation,
8x-6(68)=-32
8x-408=-32
8x=376
x=47
The interest is computed from
... I = Prt
where P is the principal amount ($569), r is the rate (0.045) and t is the time in years (250/360).
... I = $569×0.045×250/360 ≈ $17.78
Please note that time is not rounded. Rather, the exact value (25/36) is used in the calculation. The only rounding of any number is done at the end, where the amount is rounded to the nearest cent. (Your text authors should know this.)
_____
If you follow the problem instructions (which Valerie's lender will <em>not</em> do), the interest is calculated as ...
... t = 250/360 = 0.6944444... ≈ 0.69 . . . . years
... I = $569×0.045×0.69 ≈ $17.67
_____
Note the rounding of intermediate numbers (time) introduces an error of about $0.11 in the answer.
Answer:
the answer is 48:34
Step-by-step explanation:
82 - 48 = 32
so 48 : 32
Which set of orderd pairs is a function A.( -6, -4 ), (-4, -2) , ( 0, 0 ), (-4, 2 ) ,( -6, 4) B. ( -2 , 1 ) , (-4, 2) , ( 0, 3)

Answer:
The answer is D
Step-by-step explanation:
To be a function, you cannot have the same x values.
A^2 + b^2 = c^2.....a and b are the legs and c is the hypotenuse
41^2 + 40^2 = c^2
1681 + 1600 = c^2
3281 = c^2...take sqrt of both sides, eliminating the ^2
sqrt 3281 = c
57.28 ...rounds to 57 = c
so the 3 sides of ur triangle are 57,41,and 40. The perimeter is all three sides added together. So the perimeter is : 57 + 40 + 41 = 138 ft <==
