Answer:
200
Step-by-step explanation:
60% of 125 is 75
75+125=200
hope this helped!!!
Answer:
It would be $465 marked up.
Step-by-step explanation:
55% of 300 is 165.
So marked up its 465 and marked down its 135.
The first thing is to define each one:
Polynomial: expression made with constants, variables and exponents, which are combined using addition, subtraction and multiplication. Exponents can only be natural numbers and the polynomial cannot have an infinite number of terms.
Example:
This is a:
Degree: It is the exponent with the highest degree. If a monomial of those that are forming the polynomial has two unknowns, each with its exponent, these add up since we would be doing a multiplication of monomials.
Example:
The degree of this polynomial is 3 because it is the largest exponent.
Linear term coefficient: is the number that multiplies the variable with the highest exponent
Example:
In this case it is 5 because is the variable with the highest exponent
Constant term coefficient: is one that is found in a polynomial alone, that is, without multiplying the x or another unknown.
Example:
In this case it is 20 because it is the one found without multiplying any linear term (x)
Attached image with example of this.
Let y =
+ 3 be line₁
And the perpendicular angle be line₂
If a line is perpendicular to another, then the product of their gradients is -1, which means that the gradient of line₂ would be the negative reciprocal of line₁
Based on that, if the gradient of line₁ is
then, the gradient of line₂ is - 2.
Now by using the point-slope form y - y₁ = m ( x - x₁)
If line₂ passes through the line (1,8) and have gradient -2,
then by exploiting the point-slope form y - 8 = -2 (x - 1)
∴ equation of the ine perpendicular to y =
+ 3 would be
y = -2x + 10
