Which expression is equivalent to 7/8+ 3/8x-1/4y+3/4y-1/2?
Answer: the answer is in the pics
Step-by-step explanation:
The solution of the expression ( 7/8+ 3/8x-1/4y+3/4y-1/2 ) is 1 / 2 ( 3 / 4 x + y + 3/4).
What is an expression?Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication and division.
The given expression is ( 7/8+ 3/8x-1/4y+3/4y-1/2 ). The given expression will be simplified as below,
E = ( 7/8+ 3/8x-1/4y+3/4y-1/2 )
E = 1 / 2 ( 7 / 4 + 3/4x -1/2y + 3/2y - 1 )
E = 1/2 ( 3/4x +y + 3/4)
Therefore, the solution of the expression will be E = 1/2 ( 3/4x +y + 3/4).

Ellen makes and sells bookmarks. She graphs the number of bookmarks sold compared to the total money earned. What is the rate of change for the function graphed to the left?
Answer:
Given coordinates on the graph is (4,0), (8,10), (12,20).
We need to find the rate of change for the function graphed.
Actually rate of change is the second name of slope.
So, we need to find the slope between given coordinates.
We know slope formula
Let us choose first two coordinates (4,0), (8,10).
(x1,y1) = (4,0) and (x2,y2) = (8,10).
Plugging values of x1,x2,y1 and y2 in slope formula, we get
Slope=
Therefore, rate of change is 5/2 or $2.5 earned per bookmark sold.

What is the numerical coefficient in the polynomial 4y+ 6?
Answer:
4y
Step-by-step explanation:
A coefficient is a number with a variable and no sign in between them.
The numerical coefficient in the polynomial 4y+ 6 is 4.
What is expression?A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation. Let's examine the writing of phrases. The other number is x, and a number is 6 greater than half of it. In a mathematical expression, this proposition is denoted by the equation x/2 + 6.
A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.Coefficient: A coefficient is a number that is multiplied by a variable in an expression.Given expression:
4y + 6
As, A coefficient is a number that is multiplied by a variable in an expression.
here the term that contain variable is 4y.
So, the coefficient is 4.
Hence, the numerical coefficient in the polynomial 4y+ 6 is 4.
