Answer:
a=1/2
Step-by-step explanation:
From the question, the expression a(8x+7) is equivalent to 4x+3.5
Which means that multiplying 8x by a gives 4x and multiplying 7 by a gives 3.5
So, we can write the following to find the value of a

we can write the following
8ax=4x

Hence the value of a is 1/2
Answer:
w = - 
Step-by-step explanation:
3 1/4 = 1/2 + w
Cross Multiply
31(2 + w) = 4
Divide both sides by 31
=
(simplify) -> 2 + w = 
Subtract 2 from both sides
2 + w - 2 +
- 2 (simplify) -> - 
w = -

Answer:
f(x) = 3x - 7
Step-by-step explanation:
Let the independent variable of a function is 'y' and dependent variable 'x'.
Therefore, function will be in the form of y = ax - b
Now statement given in the question states that "The output is 7 more than 3 times the input."
That means y is 7 less than 3 times of x.
y = 3x - 7
Rewrite this equation in the form of a function.
f(x) = 3x - 7
