Answer:

g(f(-9))=4

Step-by-step explanation:

This is a composite function so we need to first find the value of the function on the inside in order find the value of the composite function

f(-9)=x+7=-9+7=-2

we can put -2 instead of f(-9) in the composite function

g(-2)=(-2)^2=4

What is longer 180 seconds or 3 minutes

Neporo4naja [7]

They are both the same. There are 60 seconds in one minute, so 60*3 is 180. Since 180=180, they are equal.

Find the slope-intercept form of the equation of the line that passes through the point P and makes angle with the positive x-

SIZIF [17.4K]

Answer:

The answer is " $y= -x+7$ "

Step-by-step explanation:

If $\bold{\theta = 135^{\circ}}$

point: $p=(2,5)$

Formula:

$\to m= \tan \theta \\\\\to (y-y_1)= m(x-x_1)$

$\to m= \tan \ 135^{\circ} = -1\\\\\to x_1= 2\\\\\to y_1=5$

Put the value in the above formula:

$\to y- 5 = -1(x-2)\\\\\to y- 5 = -x+2\\\\\to x+y = 5+2\\\\\to x+y=7$

$\to y= -x+7$
