ira [324]3 years ago
6 0

1. BD is perpendicular to AC - given

2.BD bisects AC - given

3. <BDC = 90 degrees; < BDA= 90 degrees - definition of perpendicular

4. m<BDC = m<BDA - substitution property

5. m<ABD = m<CBD - definition of a bisector

6. BD = BD - reflexive property

7. ABD = CBD - Angle-side-angle congruency theorem

hope this helps at all

Ryan found that the amount of plant food remaining decreased an equal amount each day, and he used the entire 72 milliliters by
BaLLatris [955]

Answer:

A function rule for the relationship between the amount of plant food remaining, f(x), and the number of days that have passed, x is f(x)=72-12x

Step-by-step explanation:

We are given that Ryan used 72 mL of food over the course of a 6 day study.

So, He used amount per day = \frac{72}{6}

He used amount per day =12 ml/day

Now we are given that t the amount of plant food remaining decreased an equal amount each day, and he used the entire 72 milliliters by the end of his study.

So, The equation becomes : f(x)=72-12x

f(x):The amount of plant food remaining

x : The number of days that have passed

Hence  a function rule for the relationship between the amount of plant food remaining, f(x), and the number of days that have passed, x is f(x)=72-12x

Why do you start with the greater number when adding on a number line
Pie
Because greater means best, and you have to start with the best!

Just kidding, the real answer is that it makes it more simple to count up on the number line. If you start with the higher number, you don't have to count up as many places because you count up whatever the value of the smaller number is

If the solution of a polynomial fucntion is x=-5 then the linear factor is (x-5)
insens350 [35]

Answer:

No. It would be (x + 5)

Step-by-step explanation:

set each of the factors as equal to 0. So if you do x+5=0 then solve for x by subtracting 5 from both sides you get x = -5

The clue is to switch the sign from the factor to get the value of the variable and vice-versa.
