Answer:

x = -5

y = -2

Step-by-step explanation:

Since you have y, plug that into the equation:

-2x - 7y = 24

-2x - 7(-2) = 24

-2x + 14 = 24

Then, subtract 14 from both sides:

-2x + 14 = 24

- 14 - 14

__________

-2x = 10

Finally, divide both sides by -2:

-2x = 10

x = -5

So now you have, x = -5 and y = -2.

Let F(x)=3x-1 and g(x)=×+2. Findf(g(x)) and g(f(x))

Fofino [41]

Solution:

Given:

$\begin{gathered} f(x)=3x-1 \\ g(x)=x+2 \end{gathered}$

To find f(g(x)):

$\begin{gathered} f(g(x))\text{ means substitute g\lparen x\rparen into f\lparen x\rparen} \\ f(g(x))=3(x+2)-1 \\ f(g(x))=3x+6-1 \\ f(g(x))=3x+5 \end{gathered}$

Therefore, f(g(x)) = 3x + 5

To find g(f(x)):

$\begin{gathered} g(f(x))\text{ means substitute f\lparen x\rparen into g\lparen x\rparen} \\ g(f(x))=(3x-1)+2 \\ g(f(x))=3x-1+2 \\ g(f(x))=3x+1 \end{gathered}$

Therefore, g(f(x)) = 3x + 1

The slope of a line is -4 and it’s y-intercept is (0,4) what is the equation of the line that is perpendicular to the first line

Rasek [7]

Original line equation: y=-4x+4

Perpendicular lines have opposite reciprocals, so the slope of the perpendicular line would be 1/4x.

Perpendicular line equation: y=1/4x+b

Plug in the coordinates that the line passes through to solve for b. Plug -8 in for x and 2 in for y.

2=1/4(-8)+b

Multiply.

2=-2+b

Add 2 to both sides.

4=b

Equation of the perpendicular line: y=1/4x+4

Hope this helps! :)
