Answer:
The first one
Step-by-step explanation:
I hope this helps with your answer :)
Vertex formula = -b/2a
-18/1 = 18.
However, this is just the x value, the vertex is (x,y)
-18*2 + 18(18) - 72 = 576
A) (18,576)
576 dollars made with 18 members is the highest amount made in one day.
B) (12,0) (6,0)
Answer:
<h2>y - 6 = 2(x - 7)</h2>
Step-by-step explanation:
The point-slope of an equation of a line:

m - slope
The formula of a slope:

We have the poinys (-1, -10) and (5, 2). Substitute:

Put the value of the slope and the coordinateso f the point (5, 2), to the equation of a line:

In the question we have y - 6 = ...
Therefore
<em>subtract 4 from both sides</em>
<em>use the distributive property</em>

<em>distributive</em>

Answer:
(x, y) = {(20, 1.3), (40, 2.6), (60, 3.9), (80, 5.2), (100, 6.5)}
Graph C represents the table of values
Step-by-step explanation:
To complete the table, substitute each value of x into the equation,
, to find each corresponding y-value.
Thus:
✔️When x = 20:



✔️When x = 40:



✔️When x = 60:



✔️When x = 80:



✔️When x = 100:



✔️<em>The graph of that represents this table of values is graph C. See attachment.</em>
You have the following equation:

In order to solve the previous equation for y, proceed as follow:
3 + y/2 = -212 subtract 3 both sides
y/2 = -212 - 3 simplify right side
y/2 = -215 multiply by 2 both sides to cancel the denominator left side
y = -215(2)
y = -430
Hence, the solution for y in the given equation is y = -430
