Answer:
6(-5)-9
-30-9
=-39
Step-by-step explanation:
<span>In order to calculate this, we can set up a simple ratio. We say that
10 empty bottles : 1 drink
100 empty bottles : x drinks
We cross multiply to form the equation:
10x = 100
Now, we can simply solve for x to determine the number of drinks we would get for 100 bottles.
x = 10
So we will get 10 drinks if we bring 100 bottles to the bottle shop.Hope this helps. Let me know if you need additional help!</span>
Answer:
y = (x - 3)² + 1
Step-by-step explanation:
the equation of a quadratic function in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
here (h, k ) = (3, 1 ) , then
y = a(x - 3)² + 1
to find a substitute (1, 5 ) into the equatiuon
5 = a(1 - 3)² + 1 ( subtract 1 from both sides )
4 = a(- 2)² = 4a ( divide both sides by 4 )
1 = a
then equation of quadratic function is
y = (x - 3)² + 1
The graph is just a straight line (parallel to the x-axis) with y- coordinate is 18
