Answer:

22

Step-by-step explanation:

f(x)=(3x+4)-(2-x)

Let x =5

f(5)=(3*5+4)-(2-5)

     Do the parentheses first

    = (15+4) - (2-5)

     = 19-(-3)

     = 19+3

    = 22

For this case we have a function of the form y = f (x), where:

f (x) = (3x + 4) - (2-x)

Simplifying, taking into account that - * + = -and - * - = +, we have:

f (x) = 3x + 4-2 + x

We add similar terms:

f (x) = 4x + 2

Now we evaluate the function at x = 5:

f (5) = 4 (5) +2\\f (5) = 20 + 2\\f (5) = 22

Answer:

f (5) = 22

Which of the following quantities are directly proportional:
Zepler [3.9K]

Answer:

Area ∝ Length.

Step-by-step explanation:

If the length of a rectangle is L and width is W, then the area of the rectangle is given by A = LW.

Now, it is given that the width of a rectangle is constant and it is 6 cm.

Therefore, the relation between the length of the rectangle in cm with the area of the rectangle in cm² will be A = 6L.

So, it is clear from the above relation that Area (A) is proportional with its length (L) and the constant of proportionality is 6. (Answer)

10 POINTS IDENTIFY THE SLOPE, Y-INTERCEPT AND GRAPH.<br> 1. Y = 2x + 3<br> 2. Y = 3/4x - 2
Alenkasestr [34]

Answer for problem 1: slope = 2, y intercept = 3

Answer for problem 2: slope = 3/4, y intercept = -2

Explanation:

Both equations are in the form y = mx+b. This is known as slope intercept form. This is because we can read off the values of the slope and y intercept very quickly. We have y = 2x+3 match up with y = mx+b. The m is the slope and b is the y intercept. So m = 2 and b = 3 for this equation. A similar situation happens with the other equation as well. It might help to rewrite the second equation into y = (3/4)x + (-2).
