Answer:

a = -18

Step-by-step explanation:

-2/3 a =12

Multiply each side by -3/2 to isolate a

-3/2 * -2/3a = 12 * -3/2

If f(x) = x 2 + 1 and g(x) = 3x + 1, find [f(2)-g(1)] 2. 1 2 9
arsen [322]
Put the argument value where the variable is, then evaluate.
For f(x), you want f(2).
  f(2) = 2² + 1 = 4+1 = 5

For g(x), you want g(1).
  g(1) = 3·1 +1 = 4

For [f(2) - g(1)] you want the difference of the above values.
  [f(2) - g(1)] = [5 - 4] = 1

Help please!! What is the slope?
Brut [27]

Answer:

C. -1/3

Step-by-step explanation:

Youre getting close here!

since you are rising by one, and running by 3, the slope will be 1/3

that means, the slope will be negative.

HELP PLEASE. Find me the answer
REY [17]

Answer:

y = 3x -1

Step-by-step explanation:

When the given points are dilated by a factor of 1/5 about the origin, each of the coordinate values is multiplied by 1/5. The points after dilation are ...

... (2/5, 1/5), (-1/5, -8/5)

The line through these points can be found starting with a 2-point form of the equation for the line.

... y -y1 = (y2 -y1)/(x2 -x1)·(x -x1)

Filling in the point values gives ...

... y -1/5 = (-8/5 -1/5)/(-1/5 -2/5)(x -2/5)

... y = (-9/5)/(-3/5)(x -2/5) +1/5 . . . . simplify parentheses, add 1/5

... y = 3x -1 . . . . . simplify

_____

The graph shows the original points and the line through them in red, and the dilated points and line in green.
