Answer: B: 56


Step-by-step explanation: First find f(g(x)). Where f(x) = -3x-4 and

g(x) = 2x-6. Replace X in f(x) with the equation for g(x)

f(g(x)) = -3(2x-6) -4. Then use the foil method and simplify.

= -6x+18-4

=-6x+14

Now sub. in the value of x with -7 and evaluate.

=-6(-7)+14

=42+14

=56

Write the equation of a line that is perpendicular to the given line and that passes through the given point. y-3=-1/5(x+2); (-2
arsen [322]

Answer:

The equation would be B) y = 5x + 17

Step-by-step explanation:

To start, you need to locate the slope of the first equation. Since the slope is the coefficient of x, we know it to be -1/5. Now, the perpendicular slope is the opposite and reciprocal of that, which makes the new slope 5.

Now that we have this, we can use the point and the slope in point-slope form to get the equation.

y - y1 = m(x - x1)

y - 7 = 5(x + 2)

y - 7 = 5x + 10

y = 5x + 17

Stella [2.4K]
C 3 1/2
The lines in between the number means absolute value. This means that’s when the number is simplified it would become positive. Since 3 1/2 isn’t negative it would just stay the same
