Answer:

2/5

Step-by-step explanation:

Since we have two points on the line, we can use the slope formula

m = ( y2-y1)/(x2-x1)

   = ( 7-5)/(9 - 4)

   = 2/5

iren [92.7K]
You simplify the fraction by dividing 2 to the nominator and the denominator. So 24/2=12, 8/2=4, 6/2=3. You can only divide a root with a root number so in this case the root three doesn't get affected

What equation represents the line that passes through points (1.-5) and (3 -17)?
zzz [600]

ALL LINES CAN BE REPRESENTED IN THE FORM f(x) = ax+b.

We know that:

f(1) = -5 \implies a\cdot(1)+b = -5 \implies a+b = -5

and

f(3) = -17 \implies a\cdot(3) +b = -17 \implies 3a+b = 17

Observe that:

3a+b = 2a+a+b = 2a+(a+b)

So:

2a+(a+b) =-17

But we know that a+b = -5, so:

2a+(a+b) =-17

2a+(-5) = -17

2a = -12

a = -6

Since:

a+b = -5

(-6)+b = -5

b = 1

So the line is:

f(x) = 1-6x

Murad ran in a track race on Tuesday he finished the race in 420 seconds how many minutes did it take to run the race?
max2010maxim [7]
The key information here is the time he took to run the race - 420 seconds

We know that there are 60 seconds in 1 minute so to find the number of minutes we divide 420 by 60 to get 7.

Murad took 7 minutes to run the race

Wheeler Company can produce a product that incurs the following costs per unit: direct materials, $10.30; direct labor, $24.30,
salantis [7]

Answer:

Incremental cost of buying = $2.50

Step-by-step explanation:

Cost per unit;

Direct materials = $10.30

Direct labor = $24.30

Overhead = $16.30

Total Overhead cost = 10.30 + 24.30 + 16.30

                                  = $50.90

Where the item is purchased,

Total cost = $46.88 + (40% × 16.30)

                = $46.88 + $6.52

                = $53.40

Cost difference = $53.40 - $50.90

                          = $2.50

There is an incremental cost of buying. This amounts to $2.50
