Answer:

**Answer:**

Isosceles

**Step-by-step explanation:**

If BD is an altitude, it splits triangle ABC into 2 triangles. It is also a median, so it splits the angle ABC into 2 congruent angles. Angle ABD and CBD are congruent. That means that angles A and C are congruent. This is true because the 2 angles at D are both right angles. Because of this, side AB and side CB are congruent. That means that this is an isosceles triangle.

The correct answer for the question that is being presented above is this one: "A rule is a function if each element in the domain goes to exactly one element in the range."

The following tables that contain correct pairs of input and output values for the function are the:

(1)

Input (x) -1.6 0.4 2.2 3.7

Output f(x) -5.5 2.5 6.75 10.75

(2)

Input (x) 1.1 2.4 5.3 6.9

Output f(x) 4.25 7.5 11.75 17.25

**Answer:**

domain (0,1,3,5,6) range (-20,-16,-8,0,4) function f(x)=4-4x

domain (-2,-1,0,3,4) range -13,-8,-3,12,17) function f(x)=5x-3

domain (-4,-3,0,2,4) range (-40,-20,0,20,40) function f(x)=10x

domain (-3,-2,-1,2,6) range (0.5,0,-1.5,3,2) function f(x)=3/x+1.5

**Step-by-step explanation:**

A patient receives 150 cc of medication in an IV drip over 4 hours. What is the rate per hour of this dose?

The average rate is 150 cc/4 hrs=37.5 cc per hour.

37.5 cc per hour you just have to divide 150cc/4 = 37.5 cc

Answer:

**Answer:**

The value of x is 18°

**Step-by-step explanation:**

Sum of the angles are 180°

3x+126=180

3x=180-126

3x=54

x=18

Movie B-

X is the running time for movie A and y the running time for movie B

X = 2y + 33

3y - × = 57

x- 2y = 33

-× + 3y = 57 => y = 90

=> x 33 + 180 = 213

X = 2y + 33

3y - × = 57

x- 2y = 33

-× + 3y = 57 => y = 90

=> x 33 + 180 = 213

use what they tell you to create the equations

a=33+2b & 57=3b-a

for this to work we need to substitute a variable to get rid of it.

look at

57=3b-a (lets switch it around s that the equation reads "a=")

57+a=3b

a=3b-57 (this is our new equations)

so now we know that

a=33+2b & a=3b-57

so we can write 33+2b=3b-57. we have now "gotten rid" of "a"

SOLVE FOR B

33+2b=3b-57 (get variable alone)

33= 3b-2b-57 (subtract and add accordingly)

33= b-57

33+57=b

90=b (this means that movie b is 90 long)

SOLVE FOR A

you can plug "b" into any of the original equations.

a=33+2b

a=33+2(90)

a=33+180

a=213

CHECK

plug "a" into any of the original equations to find "b" if b=90 then you know you've done it right

213=33+2b

213-33=2b

180=2b

180/2=b

90=b

hope this helps :)
