Answer: x² + y² = 25
Step-by-step explanation: As we have x²+y²=25 (A) as options,
x-y=1 (B)
x+y=25 (C)
x²+y²=5 (D)
We can rule out B and C as they are not circles. Circles must be
(x - xc)² + (y - yc)² = r². They must have index 2.
We have then A or D.
As the circle must pass through (3,4), we can substitute as x=3 and y=4
(A) 3² + 4² = 9 + 16 = 25 ok
(D) 3² + 4² = 9 + 16 = 25 ≠ 5
So, it is A, x² + y² = 25
Answer:
Equation: $3500+$225s=c
To transport 16 tons of sugar the Sugar Sweet Company will need $7100
Step-by-step explanation:
Notes:
$3500 to rent truck
$225 for each ton of sugar
S is sugar in tons
C is total
Truck is a set cost so you leave it alone
Sugar in the truck is $225 each ton in this case its 16 tons
$3500+$225S=C
Plug in: $3500+$225(16)=C
$3500+$3600=C
C=$7100

Answer:
x = -7
Step-by-step explanation:
Substitute the given value and solve for x
n(x) = -6x +2
44 = -6x + 2
42 = -6x . . . . . subtract 2
-7 = x . . . . . . . divide by -7
n(x) will have the value 44 for x = -7.
Answer:
There are 14 4-point questions and 26 2-point questions.
Step-by-step explanation:
m = number of 4-point questions
n = number of 2-point questions
m+n =40
4m + 2n =108
You can solve system by elimination:
Multiply the 1st equation by -4 and keep the 2nd equation the same.
−4(m+n=40) → -4m -4n= -160
4m+2n=108 add them up
-2n = -52 divide both sides by -2
n = 26
plug it back in to solve for m
m + n = 40 →m + 26 =40 subtract 26 to both sides
m = 14
