Answer:
9
Step-by-step explanation:
0.9 per cent of 1000 = 0.9(1000)/100 = 0.9(10) =9

Answer:
x (Falafel) = $5.50
y (Turkey BLT) = $7.50
z (Paninis) = $6.00
Step-by-step explanation:
Step 1: Write out systems of equations
5x + 15y + 20z = 260
8x + 18y + 14z = 263
12x + 16y + 12z = 258
There are multiple ways to solve for this systems of equations. I will use an augmented matrix for this:
Top row: [5 15 20 | 260]
Middle row: [8 18 14 | 263}
Bottom row: [12 16 12 | 258]
We find RREF form of the augmented matrix to find our answers:
Top row: [1 0 0 | 11/2]
Middle row: [0 1 0 | 15/2]
Bottom row: [0 0 1 | 6]
And we have our answer!
First we need to define this equation using point slope form.
Point slope form is represented by the following (x₁ and y₁ represent the given points, and m represents slope)
So if we plug in our values, we get
Now, in order to get it into slope-intercept form, we must isolate the Y value
So the equation is
Y = X-7
