Each pencil costs $0.40 because
4.00/10=.40
Answer:
C
Step-by-step explanation:
The equation of C is 4th-degree, so is definitely non-linear.
___
The equation of E can be multiplied by y to get x +y = 2y, which is a linear equation. It graphs as a straight line, so can be called linear on that basis. However, it has a "hole" at y=0, so could arguably be called non-linear.
Answer:
According to the pythagorean theorem, a^2 + b^2 =c^2
c signifies the hypotenuse
a and b are the two legs
the sum of the two legs squared measures will equal the measure of the hypotenuse squared.
Step-by-step explanation:
Answer: 55.56
Step-by-step explanation:
Let the unknown number be k
(45 x k) / 100 = 25
45k/100 = 25
multiply both sides by 100
45k = 25 x 100
45k = 2500
divide both sides by 45
k = 2500/45
k = 55.56
