What is the standard form of the following equation?
y + 2 = 14x
a. y = 14x −2
b. y = 14x + 2
c. x − 4y = 8
d. 14x − y =2

D

Step-by-step explanation:

The standard form of the equation of a line is

Ax + By = C ( A is a positive integer and B, C are integers )

Rearrange y + 2 = 14x into this form

Subtract y from both sides

2 = 14x - y, thus

14x - y = 2 ← in standard form → D

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
