Nora and Lila are reading the same novel for book club. Nora is on page 128 and plans to read 8 pages per day until the next clu

kicyunya [14]

Answer:

- They will be on the same page after 6.5 days or $6\frac{1}{2}$ days.

- They will be on page 180.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

$y=mx+b$

Where "m" is the slope and "b" is the y-intercept.

You know that Nora plans to read 8 pages per day until the next club meeting and she is on page 128.

With this information you can write the following equation of the line in Slope-Intercept form to represent the number of the page "y" she will be on after "x" days:

$y=8x+128$

Know that Lila is on page 102 and plans to read 12 pages per day until the next club meeting, you can write this linear equation that represent the number of the page "y" she will be on after "x" days:

$y=12x+102$

Since they will be on the same page after "x" days, make both equations equal and solve for "x":

$8x+128=12x+102\\\\26=4x\\\\x=6.5$

Substitute that value into any original equation the same page they will be on after 6.5 days (or $6\frac{1}{2}$ days):

$y=12(6.5)+102\\\\y=180$

Serjik [45]

500 guitar picks

order 15 boxes with 9 picks each

sell 19 boxes with 10 picks each

-> the store ordered about 150 picks (15 x 9 -> 15 x 10)

-> the store sold about 200 picks (19 x 10 -> 20 x 10)

it is reasonable, since they have 50 fewer picks which is about 450.

Joann has a jug containing 128 ounces of milk. She drinks 14 ounces of milk each day. Enter the function f(x) that represents th

Tatiana [17]

Answer:

$f(x)=128-14x$

Step-by-step explanation:

So, we started out with 128 ounces of milk.

Each day, Joann drinks 14 ounces of milk.

Therefore, the amount of milk left over after x days is 14 times x subtracted from 128.

Therefore, our function is:

$f(x)=128-14x$

And we're done!
