Answer:
No Solution.
Step-by-step explanation:
2x-7y=9
4x-14y=-18
------------------
-2(2x-7y)=-2(9)
4x-14y=-18
------------------------
-4x+14y=-18
4x-14y=-18
-------------------
0=-36

Answer:
45 Large and 55 Medium
Step-by-step explanation:
First, we have to make our 2 equations. One has to have the pizzas and the total pizzas and one has to have the pounds. Suppose large is L and medium is M. L + 1/2M = 100 (pounds) and L + M = 155 (pizzas). Now, we can use elimination to remove one of the variables. But first, we need to multiply the equation (L + 1/2M = 100) by -2 to get (-2L + -M = -200). We can now add the two equations together and get -L = -45. Then we divide this by -1 and get L = 45. The large pizzas and 45 and with some easy subtracting (100 - 45 = 55) we can determine the amount of medium pizzas, which is 55.
Answer:
0.75 about that in each sequence

Here is how to find the equation of the line using point-slope form
Formula for the equation of a line in <em>point-slope form</em>: y - y₁ = m(x - x₁)
Now that we have the formula, we plug in what we are given.
y - 9 = 4(x + 3)
We can covert this into slope-intercept form by solving for y.
Our equation for this line is: <em>y = 4x + 21</em>.
We can prove this by graphing the line, like so:
