Natali5045456 [20]
Equation of a line is given by y - y1 = m(x - x1); where m is the slope.
y - 4 = 2/5 (x - (-2))

<h2>Hello!</h2>

The answer is:

The correct option is A. 8.3.

<h2>Why?</h2>

To calculate the number of weeks that will pass, we need to use the given information.From the statement we know that we need to use the value of $600 substituting it as "y", and then, isolate "x", so, calculating we have:

log(y)=0.30x+0.296\\\\log(600)=0.30x+0.296\\\\2.78=0.30x+0.296\\\\2.78-0.296=0.30x\\\\x=\frac{2.78-0.296}{0.30}=8.28=8.3

Hence, the correct option is A. 8.3.

Have a nice day!

Tim Has M Dollars. Rebecca has $6 less than 1/10 Times The Number Of Dollars That Tim Has. Which Expression represents the total
Mrac [35]
M = Tim's dollar amount
R = Rebecca's dollar amount
MR = Tim and Rebecca's dollars together

R = (M x 1/10) - 6

MR = M + ((M x 1/10) - 6)

MR = 70 + ((70 x 1/10) - 6)

MR = 70 + (7 - 6)

MR = 70 + 1

MR = 71

Suppose c and d vary inversely, and d = 2 when c = 17.
balu736 [363]

Answer:

c = 34/d

d = 1/2

Step-by-step explanation:

Part A

Basic Formula

c = k/d

17 = k/2         Multiply both sides by 2

17*2 = k*2/2     Combine

34 = k

So the equation is c = 34/d

Part B

c = 68

k = 34

d = ?

68 = 34/d               Multiply both sides by d

68*d = 34 * d/d      Simplify.

68 d = 34                Divide by 68

d = 34/68                Simplify

d = 1/2
