Can a system of linear equation have exactly 2 solutions ? why or why not?

Answers

Answer:

Under normal circumstances a system of two linear equations can have 0, 1 or infinitely many solutions.

Step-by-step explanation:

Which situations can be simulated using this spinner? Select three options.A spinner with 6 equal sections.

A: Predicting the gender of a randomly chosen art teacher if 1 of 3 art teachers is female
B: Predicting the gender of a randomly chosen history teacher if 12 of 15 history teachers are female
C: Predicting the gender of a randomly chosen biology teacher if 8 of 12 biology teachers are female
D: Predicting the gender of a randomly chosen chemistry teacher if 4 of 9 chemistry teachers are female
E: Predicting the gender of a randomly chosen health teacher if 2 of 4 health teachers are female

Answers

Answer:

A: Predicting the gender of a randomly chosen art teacher if 1 of 3 art teachers is female.

C: Predicting the gender of a randomly chosen biology teacher if 8 of 12 biology teachers are female.

E: Predicting the gender of a randomly chosen health teacher if 2 of 4 health teachers are female.

Step-by-step explanation:

Notice that the spinner has 6 equal sections.

So, all situations that can be simulated with such spinner must be multiples, divisors of 6, or a number least than 6, that way, we could use the 6 equal-section spinner.

Option A uses 1 of 3, Option B uses 8 of 12, and Option E uses 2 of 4.

Therefore, the anwers are A, C and E.

Answer: A C E

What are the coordinates of the image produced by applying the composition Ro,-270 degrees o Ro,-90 degrees to the point (–5, 4)?A. (–5, 4)
B. (–4, –5)
C. (4, 5)
D. (5, –4)

Answers

On dealing with a rotation of -270 degrees or 90 degrees (both are equal to each other), it is necessary to know the relation between the x and y coordinates to know the new coordinate points of the rotated image. The rotation relation for a 90 degree rotation is:

R90 (x,y) = (-y , x)

Therefore, with that being applied to the point (-5,4), the new coordinate points of the rotated image would be: (-4,-5). Among the choices, the correct answer is B.
