Susie plans to run 2 miles per day the first week and then increase the daily distance by a half a mile each of the following we

AlekseyPX

Due to length restrictions, we kindly invite to see the explanation below to know the answer with respect to each component of the question concerning linear equations.

<h3>How to determine a linear equation describing the daily distance of a runner</h3>

In this question we need to derive an expression of the daily distance as a function of time. Now we proceed to complete the components:

Linear equations have an independent variable (t - time) and a dependent variable (x - daily distance).
We notice that the daily distance increases linearly in time, then then we have the following pattern:

t 1 2 3 4 5 6
x 2 2.5 3 3.5 4 4.5
The equation that represents the n-th term of the sequence is x(n) = 2 + 0.5 · (n - 1).
The week when Susie will run 10 miles per day is:

10 = 2 + 0.5 · (n - 1)
8 = 0.5 · (n - 1)
n - 1 = 16
n = 17

Susie will run 10 miles per day in the 17th week.
It is not reasonable to think that pattern will continue indefinitely as it is witnessed in the difficulties experimented by fastest runners in the world to increase their peak speeds.
A marathon has a distance of 26 miles, then we must solve the following equation:

26 = 2 + 0.5 · (n - 1)
24 = 0.5 · (n - 1)
48 = n - 1
n = 49

Susie should start her training 49 weeks before the marathon.

Calculating Multipliers :

9.2 Calculate multipliers for the two fractions

Denote the Least Common Multiple by L.C.M

Denote the Left Multiplier by Left_M

Denote the Right Multiplier by Right_M

Denote the Left Deniminator by L_Deno

Denote the Right Multiplier by R_Deno

Left_M = L.C.M / L_Deno = 1

Right_M = L.C.M / R_Deno = 2

Making Equivalent Fractions :

9.3 Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example : 1/2 and 2/4 are equivalent, y/(y+1)2 and (y2+y)/(y+1)3 are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

L. Mult. • L. Num. 837

—————————————————— = ———

L.C.M 50

R. Mult. • R. Num. 279 • 2

—————————————————— = ———————

L.C.M 50

Adding fractions that have a common denominator :

9.4 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

Given h(x) =1/2 x + 4 find h(-4) + 2.

Lynna [10]

Hi there! :)

$\large\boxed{h(-4) + 2 = 4}$

h(x) = 1/2x + 4

Substitute in -4 for "x" to solve for h(-4):

h(-4) = 1/2(-4) + 4

h(-4) = -2 + 4

h(-4) = 2

Since we are solving for h(-4) + 2, add:

2 + 2 = 4.
