Answer:

Hello, Have a good day

Step-by-step explanation:

The slope of the perpendicular line is the opposite sign and the inverse of the original line's slope.

(-1,-2) and (0,0).

slope = (0 - -2)/(0 - -1) = 2/1

So ,inverse and opposite would be -1/2

A parallel line has the same slope with a different y intercept

-2 = (-1/2)(-1) + b

-2 = 1/2 + b

b = -5/2

So, same slope, different b (y intercept) for a parallel line.

Composite functions g(d) = 2d - 5 h(d) = -4d +3 Find (hºg)(d)

hoa [83]

Answer:

$(h\circ g)(d)=-8d +23$

Step-by-step explanation:

Composite Function

Given g(d) and h(d) real functions, the composite function named (hog)(d) is defined as:

$(h\circ g)(d)=h(g(x))$

For practical purposes, it can be found by substituting g into h.

The functions g and h are given as:

$g(d) = 2d - 5$

$h(d) = -4d +3$

Substituting g into h:

$(h\circ g)(d)=-4(2d - 5) +3$

Operating:

$(h\circ g)(d)=-8d +20 +3$

$\boxed{(h\circ g)(d)=-8d +23}$

The high school soccer team can have no more than 27 players. Solve an inequality to determine how many players can make the tea

Dvinal [7]

Answer:

The answer is $x\leq 9.$

Step-by-step explanation:

Now, to find the number of players to make the team by solving an inequality.

Let the number of players that can make team be $x.$

Total number of players high school soccer team can have = 27.

Already players chosen by coach = $18$ .

According to question:

$x+18\leq 27$

Subtracting both sides by 18 we get:

$x\leq 9.$

Therefore, the answer is $x\leq 9.$
