An algebraic expression is a phrase in mathematics that consists of numbers such as 1,2,3 and the like, variables which are represented with letters and operations like addition, multiplication, subtraction and division. It is usually used to represent a certain situation which would relate the variables involved. To write the algebraic expression for the problem statement above, we do as follows:
Let x = number of consoles to be bought
y = number of games to be bought
z = number of controllers to bebought
C = total cost of all
The total cost would be equal to the sum of the price multiplied by the number of consoles, games and controllers bought. We write the algebraic expression as follows,
C = 299x + 59.99y + 29.99z
Answer:
oh what subject is this
Step-by-step explanation:
how do u solve it lol
Answer:

Step-by-step explanation:


Add
on both sides and subtract
on both sides.


Solve the fractions.



Multiply by the reciprocal of the fraction with the variable to isolate the variable. The reciprocal is the inverted fraction.


Answer:
y = -2x - 4.
Step-by-step explanation:
The points marked are (-2,0) and (0,-4).
The slope of line = (-4-0) / (0- -2)
= -4/2 = -2.
The y-intercept is at y = -4,
so the equation required is y = -2x - 4.
