Answer:
x = 0, x = 1
Step-by-step explanation:
Both graphs correctly plot f(x).
Only the bottom graph correctly plots g(x).
The points of intersection of f(x) and g(x) are (0, -4) and (1, -2). The x-value of these points are x = 0 and x = 1. These are the values of x for which f(x) = g(x).
Answer:
![x=-6,\\y=6](https://tex.z-dn.net/?f=x%3D-6%2C%5C%5Cy%3D6)
Step-by-step explanation:
Rewrite the system of equations as:
![\begin{cases}-13x+2y=90\\-6x+2y=48\end{cases}](https://tex.z-dn.net/?f=%5Cbegin%7Bcases%7D-13x%2B2y%3D90%5C%5C-6x%2B2y%3D48%5Cend%7Bcases%7D)
Subtract the second equation from the first to isolate
:
![-13x+2y-(-6x+2y)=42,\\-7x=42, \\\fbox{$x=-6$}](https://tex.z-dn.net/?f=-13x%2B2y-%28-6x%2B2y%29%3D42%2C%5C%5C-7x%3D42%2C%20%5C%5C%5Cfbox%7B%24x%3D-6%24%7D)
Plug in
into any of the equations above and solve for
:
![-6(-6)+2y=48,\\2y=12,\\\fbox{$y=6$}](https://tex.z-dn.net/?f=-6%28-6%29%2B2y%3D48%2C%5C%5C2y%3D12%2C%5C%5C%5Cfbox%7B%24y%3D6%24%7D)
Verify that the solution pair
works ![\checkmark](https://tex.z-dn.net/?f=%5Ccheckmark)
Therefore, the solution to this system of equations is:
![x=-6,\\y=6](https://tex.z-dn.net/?f=x%3D-6%2C%5C%5Cy%3D6)
Answer:
x=50 y=10
Step-by-step explanation:
5-p i think? How many peppermints are there in actual?
Answer:
1. y+5=4x-40
2.y=4x-45
Step-by-step explanation:
To get the slope of a line you do y₂-y₁/x₂-x₁ so we plug in the values -9+5/9-10 and we get -4
Point-slope form states y-y₁=m(x-x₁) where m is the slope so plug in the values we get y+5=4(x-10) and you get y+5=4x-40 then turn this equation into y=mx+b and get y= 4x-45
