Solve the system of equations. y = 9x y= 2x+56

Mathematics

nadya68 [22]2 years ago

Answer:

(8, 72)

Step-by-step explanation:

Here we have two separate equations for y:  y = 9x and y = 2x + 56.

Equating these equations eliminates y temporarily; we get:

9x = 2x + 56, or 7x = 56.  Dividing both sides by 7 results in x = 8.  

Then, by the first equation, y = 9(8) = 72.

The solution is (8, 72).

PLS BELP IM JUST CONFUSED
Ganezh [65]

Answer:

(0, 3)

Step-by-step explanation:

The y-intercept of any function can generally be defined as: (0, f(0)), since the y-intercept is when the function crosses the y-axis.

Anywhere on the y-axis, the x-value = 0, so the x value of the y-intercept will always be 0, and the y value is f(0), since x=0.

By looking at the graph it appears to intercept the y-axis at (0, 3) which should be the answer
