<h3>Known that</h3>
y = -2x² - 8x + 3
════════════════════
<h3>Way to do + explanation</h3>
#First, find the x coordinate first by using the formula of -b/2a
x = -b/2a = -(-8)/2(-2) = 8/-4 = -2
#After getting the x, find the y
y = -2(-2)² - 8(-2) + 3
y = -2×4 +16 + 3
y = -8 + 16 + 3
y = 11
So the vertex is
(-2,11)

Answer:
The time to complete the job is given by the expression below:
Where T = time it takes to wash all the windows
x = the number of workers assigned to the job
Step-by-step explanation:
The proportionality can be represented below as:
T ∝
T = -------------------- Equation 1
Where K is the constant of proportionality
Considering the given instance,
When T = 6, x = 4
6 =
K = 4 × 6
K = 24
Substituting the value of K into Equation 1,
T =
The answer is D, because you have to divide 12 by 2 so you get 6 then 2 times 3 to get 6, so now you should have 6+4-6 which will then become 10-6 which equals 4
If the question is, what is it? It is called this figure a pencil of lines.
А pencil of lines can consist of any number of straight, the main thing that they all had one common point. Here you can find a lot of vertical angles and rays.
