A function is shown in the table.

Anna71 [15]

Given:
x g(x)
−3 17
−1 −3
0 −4
2 13

The true statement for the given function is:
The function is decreasing from x = −3 to x = −1.

As you can see, when x = -3 the corresponding value of the function is 17 but when x = -1 the corresponding value is -3. There is a decrease of 20. → 17 - 20 = -3

triangle hij had a vertices of h (1,7),I(-4,-2),j(-3,5) write the coordinate notation for a translation of 3 units to the right

yanalaym [24]

The coordinates are H'(4,11), I'(-1,2), J' (0,9).

Step-by-step explanation:

Triangle HIJ had a vertices of h(1,7), i(-4,-2), j(-3,5)

Here we are going to translate the pre-image.

Translation up means we have to add the translated units to the y-coordinate of the (x,y) point of the preimage.

Translation to the right means we have to add the translated units to the x-coordinate of the (x,y) point of the preimage.

So the points of the image have the change in points using the translation as,

(x+3, y+4)

So the points of the triangle may be changed as,

H (1,7) → H'(1+3, 7+4) → H'(4,11)

I (-4,-2) → I' (-1,2)

J (-3,5) → J' (0,9)

A positive integer is 2 less than another. If the sum of the reciprocal of the smaller and twice

valentinak56 [21]

Answer:

Step-by-step explanation:

Let x represent the smaller integer.

Let y represent the larger integer.

A positive integer is 2 less than another. It means that

y = x + 2

If the sum of the reciprocal of the smaller and twice the reciprocal of the larger is 11/15, it means that

1/x + 2/y = 11/15- - - - - - - - - - 1

Substituting y = x + 2 into equation 1, it becomes

1/x + 2/(x + 2) = 11/15

Considering the left hand side of the equation, it becomes

(x + 2 + 2x)/x(x + 2)

Therefore,

(3x + 2)/(x² + 2x) = 11/15

Cross multiplying, it becomes

15(3x + 2) = 11(x² + 2x)

45x + 30 = 11x² + 22x

11x² + 22x - 45x - 30 = 0

11x² - 23x - 30 = 0

11x² + 10x - 33x - 30 = 0

x(11x + 10) - 3(11 + 10) =℅0

(x - 3)(11x + 10) = 0

x - 3 = 0 or 11x + 10 = 0

x = 3 or x = - 10/11

Since it us a positive integer, the smaller integer is 3 and the larger integer is 3 + 2 = 5

(SAT prep) In △ABC, AB = BC =20, DE ≈ 9.28. Approximate BD.

ankoles [38]

Answer: BD = 5.36 ≈ 5.4

Step-by-step explanation:

length of line AB = length of line BC = 20, line DE ≈ 9.28

Since the length of line AB and line BC are equal, it follows that the length of line BD and line EC are also equal. Therefore, to get the length of line BD will be the difference between the length of lines BC and DE; the result is then divided by 2. The result gives us the length of line BD or line EC because the length of lines BD and EC are equal [BD = EC]
