Answer:
(4, 1)
Step-by-step explanation:
3x+4y=16 /*4
-4x-3y= - 19 /*3
12x + 16y = 64
<u>- 12x - 9y = - 57 </u>
7y = 7
y = 1
3x+4y=16
3x + 4*1 = 16
3x = 16 - 4
3x = 12
x = 4
Answer:
-2/5
2
Step-by-step explanation:
Slope is rise over run according to my former algebra teacher, but I learned it differently (still correct tho).
The first moves 2 units down so negative 2, and moves 5 units right, so -2/5 since the rise is -2, and run is 5.
The second one moves 2 x-units for every 1 y-unit, so the slope is 2,
Answer:
Distance from the airport = 894.43 km
Step-by-step explanation:
Displacement and Velocity
The velocity of an object assumed as constant in time can be computed as
Where 
is the displacement. Both the velocity and displacement are vectors. The displacement can be computed from the above relation as
The plane goes at 400 Km/h on a course of 120° for 2 hours. We can compute the components of the velocity as
The displacement of the plane in 2 hours is
Now the plane keeps the same speed but now its course is 210° for 1 hour. The components of the velocity are
The displacement in 1 hour is
The total displacement is the vector sum of both
The distance from the airport is the module of the displacement:
Let
T---------> <span>the tax rate on the parts in $
we know that
$18.75=$15+$3.50+$T
T=18.75-15-3.5
T=$0.25
so
$3.50----------> 100%
$0.25--------> x
x=0.25*100/3.50------> x=7.14%------> x=7.1%
the answer is
7.1%</span>
<span>3(9x-9)=16+3(-2x+9)
27x - 27 = 16 - 6x + 27
27x + 6x = 16 + 27 + 27
33x = 70
x = 70/33
x = 2 4/33
In short, Your Answer would be 70/33 or 2 4/33
Hope this helps!</span>
