I am pretty sure it is 120 or 30
answer:
A is the answer because you need to divide it and add it together and then u get 3.25 which is also a fraction for 3/4
Only 4 because result is (x-4)(x-4) that means (x-4)^2=0
So
X-4=0
X=4
Answer:
a) y=0.75x+12 (y=ax+b)
b)a=0.75
c)b=12 (b=y-intercept, the place where the graph hits the Y axis). It's the starting cost, the cost that will be paid only one time
d) starts at (0,12) and goes up +0.75 each time
To solve for the solution of this system of linear equation, it is best to use substitution. From the first equation, x = 3y
Substituting the expression on the right for the value of x on the second equation,
-2(3y) + 3y = 16
Solving for the value of y gives y = -5 1/3
With this value of y, solving for x gives x = -16
Thus, the solution for this system of linear equation is (-16, -5 1/3)
