Answer:
y = - 3x - 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 3, then
y = - 3x + c ← is the partial equation
To find c substitute (- 2, - 1) into the partial equation
- 1 = 6 + c ⇒ c = - 1 - 6 = - 7
y = - 3x - 7 ← equation of line
Answer:
0.08 g
Step-by-step explanation:
20% = 0.2
0.2*0.4=0.08 g
Answer:
The answer to Jodie ran at an average speed of 6 km/h for 40 minutes.
How far did she run in km is 4 km.
Step-by-step explanation:
6 km/1 hr is the same as 6 km/ 60 min. Set up a proportion of (x km/ 6 km) = ( 40 min/ 60 min)
Thus 60x = 240.... x=4/
=4 I think that could be the answer
Answer:
$28 3/4
Step-by-step explanation:
One way of doing this is to sum up the increases and the decreases of the price, separately. One then adds the increases to the beginning price ($33 3/8) and subtracts the decreases from this sum:
$33 3/8 + ($4 1/4) - ($8 7/8), where $33 3/8 is the beginning price,
$4 1/4 is the sum of the price increases
for the day, and $8 7/8 is the sum of the
price decreases for the day.
Then we have:
$33 3/8 + $4 2/8 - $ 8 7/8
Here we need sum up the beginning price and the price increase for the day first:
$33 3/8 + $4 2/8 = $37 5/8
We cannot subtract $8 7/8 from $37 5/8 without borrowing. Borrowing, we get:
$36 13/8
and from this we subtract $8 7/8:
$36 13/8
- $ 8 7/8
----------------
$28 6/8
This can be reduced to $28 3/4. This was the closing price.
