Answer:

x=9, x>-9, x=7

Step-by-step explanation:

15x + 121 = 256 \\ 15x = 256 - 121 \\ 15x = 135 \\  \frac{15x}{15}  =  \frac{135}{15}  \\ x = 9

4x + 8 > 2x - 10 \\ 4x - 2x  >  - 10 - 8 \\ 2x =  - 18 \\  \frac{2x}{2}  =   \frac{ - 18}{2}  \\ x >  - 9

5x + 7 = 42 \\ 5x = 42 - 7 \\ 5x = 35 \\  \frac{5x}{5}  =  \frac{35}{5}  \\ x = 7

What is the equation of a line passing through the points 6,3 and -4,3 so y=?
Mice21 [21]
Equation of a line using 2 points. first find the slope

m= (y2-y1)/(x2-x1)= (3-3)/(-4-6)= 0/-10 = 0
m=0

using y-y1=m(x-x1)
we get
y-3=0(x-6)
y-3=0

y=3 is the equation of the line

Find f(x) and g(x) so the function can be expressed as y = f(g(x)). (1 point)
Rina8888 [55]

Answer:

g(x)=x^2+4 and f(x)=\frac{8}{x}


Step-by-step explanation:

If we want to express y as y=f(g(x)), this means that put the function g(x) into x of f(x) to get y.

The function y is given as y=\frac{8}{x^{2}+4}

<u>So we need to figure out a function g(x) that we can put into another f(x) to get y</u>

If we let g(x)=x^2+4 and f(x)=\frac{8}{x}, we can clearly see that putting g(x) into x of f(x) will give us  \frac{8}{x^2+4}, which is y.


Hence g(x)=x^2+4 and f(x)=\frac{8}{x}
