Step 1: Find the slope

(y-y)/(x-x) = (8-8)/(9+4) = 0

Step 2: Substitute into the slope intercept equation

y - y = m(x - x)

y - 8 = 0(x - 9)

If the problem just wants plain, slope intercept form, then this is your answer.

If not, y = 8

Answer:

$4\frac{1}{2}$ feet further.

Step-by-step explanation:

Since these are mixed numbers that are both in fourths, we can easily subtract the two numbers. However, I find it easier if we first convert both mixed numbers into improper fractions.

$5\frac{1}{4} = \frac{5\cdot4+1}{4} = \frac{21}{4}$

$9\frac{3}{4} = \frac{9\cdot4+3}{4} = \frac{39}{4}$

Now we can subtract the numerators:

$\frac{39}{4} - \frac{21}{4} = \frac{39-21}{4} = \frac{18}{4}$

$\frac{18}{4}$ simplifies down to $\frac{9}{2}$ .

Converting $\frac{9}{2}$ to a mixed number is easy - 2 goes into 9 4 times (8) with one remainder so:

$4\frac{1}{2}$ .

Hope this helped!

AnnyKZ [126]

Answer:

Working together, they will finish the job in 1 hour, 25 minutes, and 42.6 seconds.

Step-by-step explanation:

Given that Ted can change an advertisement on a billboard in 5 hours, while Marie can do the same job in 2 hours, to determine how long it would take them if they worked together the following calculation must be performed:

Ted 1/5 in 1 hour

Marie 1/2 in 1 hour

1/5 + 1/2 = X

5X + 2X = 10

7X = 10

X = 10/7

X = 1 3/7

60/7 x 3 = 25.71

60 x 0.71 = 42.6

So, working together, they will finish the job in 1 hour, 25 minutes, and 42.6 seconds.
