Answer:
<h3>Attachment</h3>
Step-by-step explanation:
Convert to the slope-intercept form (<em>y = mx + b</em>):
<em>divide both sides by 2</em>
We choose any three x values and calculate the y value:
for x = -1
for x = 1
for x = -3
Mark the points on the coordinate plane and draw a line through the given points.
Answer:
yes
Step-by-step explanation:
Answer:
Step-by-step explanation:
A value that is 9.75 less than p can be represented by the expression ...
p - 9.75
We are told that value is equal to 64, so the equation is ...
64 = p - 9.75
__
This equation is solved by adding 9.75 to both sides.
64 +9.75 = p -9.75 +9.75
73.75 = p
The store price is $73.75.
The answer is 16. because the 4 lines up with the 16
Answer:
y - value of the vertex is 49.
Step-by-step explanation:
Given function is f(x) = -(x - 3)(x + 11)
f(x) = -(x² - 3x + 11x - 33)
= -(x² + 8x - 33)
= -(x² + 8x + 16 - 49)
= -[(x + 4)² - 49]
= -(x + 4)² + 49
Comparing this equation with the vertex form of a quadratic function,
f(x) = -(x - h)² + k
Where (h, k) is the vertex of the function.
Vertex of the parabola is (-4, 49)
Therefore, y-value of the vertex is 49.
