Suppose you are determining the growth rate of two species of plants. Species A is 12 cm tall and grows 2 cm per month. Species B is 10 cm tall and grows 3 cm per month. Which system of equations models the height of each species H(m) as a function of months m.H(m ) = 2 + 12m
H(m ) = 3 + 10m

H(m ) = 2 + 12m
H(m ) = 10 + 3m

H(m ) = 12 + 2m
H(m ) = 3 + 10m

H(m ) = 12 + 2m
H(m ) = 10 + 3m

Answers

Answer 1
Answer:

Answer:

The equations for the growth of two type of species are

H(m) = 12 + 2m

H(m) = 10 + 3m

Step-by-step explanation:

As given

The growth rate of two species of plants.

Species A is 12 cm tall and grows 2 cm per month.

The height of each species is represented by H(m) as a function of months m.

Than the equation becomes

H(m) = 12 + 2m

As given

Species B is 10 cm tall and grows 3 cm per month.

Than the equation becomes

H(m) = 10 + 3m

Than the equations for the growth of two type of species are

H(m) = 12 + 2m

H(m) = 10 + 3m
Answer 2
Answer: H(m) = 12 + 2m
H(m) = 10 + 3m

You want to leave a 15% tip on a meal that cost $65.00.

First, convert the 15% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.

Second, you need to find out what 15% of your $65.00 meal cost is.This is always done by multiplying 0.15 by $65.00, or

0.15 x $65.00=$9.75.

So, the amount of tip you are going to leave is $9.75.

This makes the total cost of your meal (to write on your charge slip or other payment)

$65.00 + $9.75 = $74.75.
A: y=50x+75
EXP: The x value 0 is at 75, making that the y-intercept. Rise/run for rise 1 -> 2 is up 50, making slope 50(x). Put it together giving you y=50x+75

If f(x+5)=x^2+kx+30 what is K equalled to?

Answers

f(x+5) means for every x, it is x+5

ok so since it is 2nd degree, we do exponent
f(x)=x^2
f(x+5)=(x+5)^2=x^2+10x+25
we need 5 more
f(x)=x^2+5
f(x+5)=x^2+10x+25+5=x^2+10x+30

17g+6=20g+3 Solve for the variable g.

Answers

1g is the answer

minus 6 and 3=3
minus 17 and 20
3g=g
1=g

You need to isolate the variable g onto one side. Since we're going backwards, we need to do the opposite of the order of operations. Step one is to subtract 20g from both sides. 17g-20g is -3g. -3g+6=3. Now, subtract 6. 3-6=-3. 
-3g=-3. Finally, divide both sides by -3. -3/-3 is 1, so G is 1. 

What are the zeros of (x-2)(x^2-9)

Answers

So because the factors of the equation are (x-2), (x+3) and (x-3), you set them equal to zero and you get x=2, -3, and 3
                         (x - 2)(x² - 9) = 0
          (x - 2)(x² + 3x - 3x - 9) = 0
(x - 2)(x(x) + x(3) - 3(x) - 3(3)) = 0
                 (x - 2)(x - 3)(x + 3) = 0
x - 2 = 0  or  x - 3 = 0  or  x + 3 = 0
  + 2 + 2         + 3  + 3          - 3  - 3
     x = 2             x = 3             x = -3

What is
the ratio equal for 90:18

Answers

u have to think what numbers go into both those numbers
the biggest number that will go in 
9 goes into 90 and 18 
it goes to 90 ten times 
and into 18 twice 
so the ratio in its simplest form it 10:2 
To find the ratio between 2 numbers, you need to find the GCF of those 2 numbers. If the GCF is the ratio, the ratio is in it's simplest form.
GCF of 90 and 18 is 18
divide both numbers by the GCF and the final simplest ratio is 5:1
