Answer:

y = 15x

Step-by-step explanation:

Part 2's answer is 15. The constant of proportionality equals k. All you need to do for part 3, then, is to substitute 15 into k for the y = kx equation.

Solve the system of linear equations by graphing, round the solution to the nearest tenth.
algol [13]
For this case we have the following system of equations:
 y = -0.25x + 4.7

y = 4.9x-1.64
 When solving the problem graphically we must take into account the following:
 1) The solution of the system of equations is given by the intersection of both functions.
 2) The solution is an ordered pair of the form (x, y)
 For this case we observe that the solution is given by:
 (x, y) = (1.23, 4.39)

 Note: see attached image.
 Answer:
 
The approximate solution to the system is (1.23, 4.39)

So by hour 3 you should be at 16

What is the coordinates of T' if T(-4,2) after a rotation of the triangle 180°about the origin?​
guapka [62]

Answer:

T'(4, -2)

Step-by-step explanation:

Rotation 180° about the origin (same as reflection across the origin) negates both coordinates:

T' = -T = -(-4, 2)

T' = (4, -2)
