F(6) = 7(6) - 4
f(6) = 42 - 4
f(6) = 38
Hope this helps!
Answer:
look below
Step-by-step explanation:
i dont know what that +... thing is
but when youre adding the negatives youre really just adding that number so this is just
48+45+42+81+84
45+42 is 87
now we have
48 + 87 + 81 + 84
87 + 81 is 168
48 + 84 is 132
now we have
168 + 132 and that is exactly 300
again dont know what the ... is so cant help you there
Answer:
- m = 4/3; b = -4
- m = 3; b = -6
Step-by-step explanation:
In each case, <em>solve for y</em>. You do this by getting the y-term by itself, then dividing by the coefficient of y.
<h3>1.</h3>
-3y = -4x +12 . . . . . subtract 4x
y = 4/3x -4 . . . . . . . divide by -3
The slope is 4/3; the y-intercept is -4.
__
<h3>2.</h3>
y = 3x -6 . . . . . . divide by 2
The slope is 3; the y-intercept is -6.

<em>Additional comment</em>
Whatever you do to one side of the equation, you must also do to the other side. When we say "subtract 4x", that means 4x is subtracted from both sides of the equation. The reason for doing that in the first equation is to eliminate the 4x term from the left side.
(Sometimes, you may see operations described as "move ...". There is no property of equality called "move." There are <em>addition</em>, <em>subtraction</em>, <em>multiplication</em>, <em>division</em>, and <em>substitution</em> properties of equality. Any equation solving process will make use of one or more of these.)
