The vertex is the lowest/highest point, depending on if the parabola opens upwards or downwards.

So because the vertex opens upwards, we are looking for the lowest point which is at (2,-3).

Determine the domain for the graphed function:<br> Please help meeee
Rom4ik [11]

Answer:

D

Step-by-step explanation:

First, domain refers to the x axis. So you would find the lowest number on the X axis, -2, and then you look at the kind of dot on that number. It is an open dot, which means that it is all the numbers up to -2, but does not include -2. Then you find the highest number, in this case 2. Looking at the dot that is marking it, it is a closed dot, meaning it includes the number 2. So the domain would be numbers between -2 and 2, but does not include -2. all numbers greater than -2, x, all numbers less than and equal to 2.

What is a factor of 15xy-45x-6y+18?<br><br> A. Y-2<br> B. 5x-3<br> C. 5x-2<br> D. Y-6
AfilCa [17]
Factor the following:
15 x y - 45 x - 6 y + 18
Factor 3 out of 15 x y - 45 x - 6 y + 18:
3 (5 x y - 15 x - 2 y + 6)
Factor terms by grouping. 5 x y - 15 x - 2 y + 6 = (5 x y - 2 y) + (6 - 15 x) = y (5 x - 2) - 3 (5 x - 2):
3 y (5 x - 2) - 3 (5 x - 2)
Factor 5 x - 2 from y (5 x - 2) - 3 (5 x - 2):
Answer:  3 (5 x - 2) (y - 3)

1/3 + 1/4 + 1/6<br> PLEASE SHOW WORK, thank you
Dovator [93]

Answer:

3/4

Step-by-step explanation:

1/3 + 1/4 + 1/6

notice that the denominators consists of the numbers 3, 4 and 6 and that the lowest common multiple for all 3 numbers is 12, hence all these fractions can be expressed with a denominator of 12

i.e

1/3 = 4/12

1/4 = 3/12

1/6 = 2/12

hence,

1/3 + 1/4 + 1/6

= 4/12 + 3/12 + 2/12

= (4+3+2) / 12

= 9/12  (simply)

= 3/4

Which postulate proves the two triangles congruent?
lorasvet [3.4K]

Answer:

B) SAS

Step-by-step explanation:

Notice that there are two pairs of congruent sides, AC is congruent with ZX, and BC is congruent with YZ. Since there's one angle in each triangle that's congruent to each other, we can say B is the only true answer.
