29.) This is simply interpreting the linear function.
The function:
96+2.1x
a.) The 96 is what you start with from the beginning. So, we know Rachel weighed 96 ounces when she was born.
b.) Again, interpretation. The 2.1 is the slope, or the change in the line. So we know that Rachel gains 2.1 ounces each day.
30.) For this one, you just have to plug 9 into the equation for x.

You could write a set of equations or use the interest formula, A(t)=P(1+r/n)^nt
where p equals the principal amount, r equals the rate/ percentage of interest, n equals the compounding periods and t equals time

Look at the Picture. Look at the Picture.
lys-0071 [83]

Answer:

325 square inches

Step-by-step explanation:

Consider the attachment below for further reference. Ideally we would split this figure into parts, and solve as demonstrated by the attachment. I have labeled each rectangle as rectangle 1, rectangle 2, rectangle 3 etc. ;

Rectangle 1 Area = 17 in * 5 in = 85 square in\\Rectangle 2 Area = ( 17 in - 5 in ) * 14 in  = 168 square in,\\Rectangle 3 Area = ( 12 in - 3 in ) * 8 in = 72 square in\\\\Total Area = 85 + 168 + 72 = 325 square inches

<em>Hope that helps!</em>

Three students are working to find the solution set of this system of equations: y = 3x + 10 2y = 6x – 4
ivanzaharov [21]

Answer:

Step-by-step explanation:

Since this is a system with two equations, we can easily use a graphing calculator to find the solution

The intersection between the graphs of the equations

y = 3x + 10

2y = 6x – 4   (if we divide by two)

y = 3x - 2

However, we can see that the graphs have the same slope m = 3

Since both equations are not equal, there is no solution for this system

Please see attached graph. The lines are parallel and they never touch each other.

Lisa [10]

Answer:

D(t)=3 \frac{miles}{hour} +0.05*\frac{miles}{hour*F}(80F-t)

Step-by-step explanation:

The average speed in function of the temperature:

S(t)=6 \frac{miles}{hour} +0.1*\frac{miles}{hour*F}(80F-t)

The distance in function of the average speed:

D(x)=0.5*x

x and S are the same

D(t)=0.5*[6 \frac{miles}{hour} +0.1*\frac{miles}{hour*F}(80F-t)]

D(t)=3 \frac{miles}{hour} +0.05*\frac{miles}{hour*F}(80F-t)
