Let f(x) = -3x2 – 1 and g(x) = -5x. Find f(g(x)).

Mathematics

Substitute g(x) where x is in the definition of f(x).
  f(g(x)) = -3(g(x))^2 - 1
  f(g(x)) = -3(-5x)^2 - 1
  = -3(25x^2) - 1

f(g(x)) = -75x^2 - 1

PLEASE HELP !!! URGENT!!!

Answer:

best ans is { f(x)| –∞ < f(x) ≤ 4}

Step-by-step explanation:

usually to find the range of a fn, u need to see what the value can be. the graph show only a small range of x values. but u can see f(x) is definitely <  4. so the ans is { f(x)| –∞ < f(x) ≤ 4}

Find the equation of the line.​
JulsSmile [24]
Answer: y = 2x + 5

Explanation:

The slope (number before x) is rise (change in y)/run (change in x). The rise is 6 and the run is 3, so the slope is 6/3, or 2.

The second blank is the y-intercept, or where the line crosses the vertical axis. This point is at 5.

Hope this helps!

If two lines having equations 3x+5y-16=0 and 4y-mx= 20 are parallel, find the value of m
sergejj [24]

Answer:

m = -3/5

Step-by-step explanation:

since both lines are given as "parallel", they will have the same slope, so we only need to solve for one.

we will put this equation into slope-intercept form to find the slope

3x + 5y - 16 = 0

3x + 5y = 16

5y = -3x + 16

y = -3/5x + 16/5

m = -3/5

Answer:

(-4,16)

Step-by-step explanation:

1/2x+18=5/2+26

1/2x=5/2x+8

-2=8 divided by -2

Equals x=-4

Plug in -4 in one of the equations

1/2(-4)=18= 16
