Answer:
x = 5/39
, y = 539/39
Step-by-step explanation:
Solve the following system:
{y - 2.5 x = 13.5
12.25 x - y = -12.25
In the first equation, look to solve for y:
{y - 2.5 x = 13.5
12.25 x - y = -12.25
y - 2.5 x = y - (5 x)/2 and 13.5 = 27/2:
y - (5 x)/2 = 27/2
Add (5 x)/2 to both sides:
{y = 1/2 (5 x + 27)
12.25 x - y = -12.25
Substitute y = 1/2 (5 x + 27) into the second equation:
{y = 1/2 (5 x + 27)
1/2 (-5 x - 27) + 12.25 x = -12.25
(-5 x - 27)/2 + 12.25 x = 12.25 x + (-(5 x)/2 - 27/2) = 9.75 x - 27/2:
{y = 1/2 (5 x + 27)
9.75 x - 27/2 = -12.25
In the second equation, look to solve for x:
{y = 1/2 (5 x + 27)
9.75 x - 27/2 = -12.25
9.75 x - 27/2 = (39 x)/4 - 27/2 and -12.25 = -49/4:
(39 x)/4 - 27/2 = -49/4
Add 27/2 to both sides:
{y = 1/2 (5 x + 27)
(39 x)/4 = 5/4
Multiply both sides by 4/39:
{y = 1/2 (5 x + 27)
x = 5/39
Substitute x = 5/39 into the first equation:
{y = 539/39
x = 5/39
Collect results in alphabetical order:

Answer:
Translation down 5 units.
Step-by-step explanation:
The - 5 results in a shift of the whole graph down 5 units.
Each value of g(x) is 5 units less f(x).
<u>Statement</u><u>:</u>
A person is running at an initial velocity of 3.7 m/s. If the person is accelerating at 2 m/s².
<u>To </u><u>find </u><u>out:</u>
The person's final velocity after 3 s.
<u>Solution</u><u>:</u>
- Initial velocity (u) = 3.7 m/s
- Acceleration (a) = 2 m/s²
- Time taken (t) = 3 s
- We know, the equation of motion,
- v = u + at
- Putting the values in the above equation, we get,
- v = 3.7 m/s + 2 m/s² × 3 s
- or, v = 3.7 m/s + 6 m/s
- or, v = 9.7 m/s
<u>Answer</u><u>:</u>
The final velocity is 9.7 m/s in the direction of the motion.
