It is C. (0, 1), (-5/2, 6)

These are the points where the two graphs interject one another.

You can just plug these graphs into desmos. C: Have a nice night/day.

Answer:

Option C - (0,1), (-5/2,6)

Step-by-step explanation:

Given : The system of equations y=2x^2+3x+1 and y=-2x+1

To find : Solve the system by graphing ?

Solution :

Let the equation 1 - y=2x^2+3x+1  is a quadratic equation.

Equation 2 - y=-2x+1 is a linear equation.

Plot these equation in the graphing tool,

Equation 1 y=2x^2+3x+1  is shown by blue line with vertex (-0.75,-0.125).

Equation 2  y=-2x+1  is shown by green line passing through (0.5,0) and (0,1).

The intersection point of the equations is the solution of the system i.e. (-2.5,6) and (0,1).

The solution is (0,1), (-5/2,6).

Refer the attached figure below.

Therefore, Option C is correct.

The probability of contamination in batch 1 of a drug (event A) is 0.16, and the probability of contamination in batch 2 of the
VLD [36.1K]
We have:
Event A ⇒ P(A) = 0.16
Event B ⇒ P(B) = 0.09
Probability of event B given event A happening, P(B|A) = P(A∩B) / P(A) = 0.12

By the conditional probability, the probability of event A and event B happens together is given by:
P(B|A) = P(A∩B) ÷ P(A)
P(B|A) = P(A∩B) ÷ 0.16
0.12 = P(A∩B) ÷ 0.16
P(A∩B) = 0.12 × 0.16
P(A∩B) = 0.0192

When two events are independent, P(A) × P(B) = P(A∩B) so if P(A∩B) = 0.0192, then P(B) will be 0.0192 ÷ 0.16 = 0.12 (which take us back to P(B|A))

Since P(B|A) does not equal to P(B), event A and event B are not independent.

Answer: <span>Events A and B are not independent because P(B|A) ≠ P(B)</span>

What are the vertices of triangle A'B'C' produced by (x, y) -&gt; (x+5, y-2)?
lara [203]

Answer:

The vertices of triangle A'B'C' produced by (x, y)  →  (x+5, y-2)  will be:

  • A'(8, -2)
  • B'(8, 0)
  • C'(5, -5)

Step-by-step explanation:

Given the vertices of an original triangle ΔABC such that

  • A = (3, 0)
  • B = (3, 2)
  • C = (0, -3)

As the rule of translation is given by

Translation: (x, y)  →  (x+5, y-2)

So, after the translation the vertices of the original triangle ΔABC will be translated as:

A = (3, 0)  → (x+5, y-2)  ⇒ (3+5, 0-2) = A'(8, -2)

B = (3, 2)  →  (x+5, y-2)  ⇒ (3+5, 2-2) = B'(8, 0)

C = (0, -3) → (x+5, y-2)  ⇒ (0+5, -3-2) = C'(5, -5)

Therefore, the vertices of triangle A'B'C' produced by (x, y)  →  (x+5, y-2)  will be:

  • A'(8, -2)
  • B'(8, 0)
  • C'(5, -5)
