Answer:
C ( i think)
Step-by-step explanation:
Answer:
y = 
Step-by-step explanation:
given y varies as the square of x then the equation relating them is
y = kx² ← k is the constant of variation
to find k use the given condition y = 25 when x = 3
k =
= 
⇒ y =
x²
when x = 2
y =
× 4 = 
Answer:
a) The difference of a number and six is no less than 15
x - 6 ≥ 15
b) 25 plus a number is at least 13
25 + x ≥ 13
c) g decreased by 25 is at most five
g - 25 ≤ 5
Step-by-step explanation:
a) The difference of a number and six is no less than 15
Let the number be represented by x
We difference is involved in a mathematics question, it requires the application of Subtraction operation, hence:
x - 6 ≥ 15
b) 25 plus a number is at least 13
Let the unknown number be represented by x
When at least is used in Mathematics, is means greater than or equal to a particular value,
Hence,
25 + x ≥ 13
c) g decreased by 25 is at most five
At most means less than or equal to a particular value, hence:
g - 25 ≤ 5
The vertex form of parabola is,

Where
is vertex point.
In this case our parabola is given by,

Hence the vertex is at
.

By rounding $24.97 to $25, she actually added 3 cents to the price of the shirt. After adding $25 + $13.75 and getting $38.75, she needs to subtract the 3 cents she added to find the exact sum which is $38.72.
Answer: A. Subtract $0.03
