I think it should be -6, because line segment equals 12 and it's midpoint will be 12/2 = 6, so you must go down by 6 from (0,0) point on y axis which is 0-6=-6
So the point will be (0, -6)
Ducks have 1 head. Dogs have 1 head.
Ducks have 2 feet. Dogs have 4 feet.
If x = no. of ducks and g = no. of dogs
x + g = 25
2x + 4g = 80
Let's use substitution to solve.
x + g = 25 ⇒ x = 25 - g
replace x with 25 - g in the other equation and solve for g
2x + 4g = 80
2(25 - g) + 4g = 80
50 - 2g + 4g = 80
50 + 2g = 80
2g = 30
g = 15
Now use g = 15 in an earlier equation to find x.
x + g = 25
x + 15 = 25
x = 10
To compare the speed for the both of them, it would be helpful to convert the units to the same units in this case to units of meters per minute. We calculate as follows:
27 / 60 minutes = 0.45 km/minute
0.45 × 1000 = 450 m/minute
14 x 60 = 840 dm/minute
840 / 10 = 84 m/minute
450 - 84 =<span> 366 m/minute faster than the girl</span>
Answer:
y = -6x + 3
Step-by-step explanation:
The format of slope intercept equations is: y = mx + b
b is the y intercept and m is the slope.
The y intercept here is 3 (0,3).
The line goes to the right 1 unit and down 6 units. The slope is rise over run, so the rise is -6 and the run is 1. That makes the slope: -6
Plugging this into the variables, we get:
y = -6x + 3
