You have to put it in y=mx+b form so you subtract 15 to both sides so put it under the 3x and then it would be y=3x-15. Hope it's correct.
Answer: The required value of y is 22.
Step-by-step explanation: We are given the following function of a and b :
We are to find the value of y when a = 1 and b = 2.
To find the required value of y, we need to substitute the values of a and b in equation (i).
From (i), we get
Thus, the required value of y is 22.
A)f(4)=6(4)-9=24-9=15
B)f(1/2)=6(1/2)-9=3-9= -6
First, to make the equation easier to read, you want to add the x’s together. you should then get 2.6x-3.8=-9. then, you want to add the 3.8 to both sides, to make the x stand alone. you should end up with 2.6x=-5.2. to find x, you then want to divide both sides by 2.6. your final answer after dividing should be x=-2
