Answer:

$g(f(5))=64$

Step-by-step explanation:

we have

$f(x)=x+3$

$g(x)=x^{2}$

we know that

$g(f(x))=(x+3)^{2}$

$g(f(5))=(5+3)^{2}=64$

PLZZ HELP I’m bad at math.

Answer:

y< $\frac{-1}{3}$ x+1 is inequality shown on graph.

Step-by-step explanation:

The graph shows representation of inequality,

Here, Line passes through points say, A(3,0) and B(0,1)

The slope of line is given by m= $\frac{Y2-Y1}{X2-X1}$

m= $\frac{Y2-Y1}{X2-X1}$

m= $\frac{1-0}{0-3}$

m= $\frac{-1}{3}$

and Y-intercept is c=1

The equation of line is given by y=mx+c

y= $\frac{-1}{3}$ x+1 is equation of line in graph.

To decide which side you are going to shaded area on the graph

Take test of origin.

If (0,0) is statisfy the equation then, shaded the graph towards the origin.

Let suppose,

Take, y< $\frac{-1}{3}$ x+1

0< $\frac{-1}{3}$ (0)+1

0<1

TRUE,

Therefore, y< $\frac{-1}{3}$ x+1 is inequality shown on graph.

Line t has an equation of y = -8x + 7. Line u includes the point (-1, 7) and is parallel to line

umka2103 [35]

Answer:

y = -8x - 1

Step-by-step explanation:

y = mx + b

7 = -8 (-1) + b Substitute in points for x and y. Substitute -8 for m (parallel)

7 = 8 + b

-1 = b
