Answer:

The series of transformations that moves pentagon FGHIJ onto pentagon F'G'H'I'J' is;

C. Translation, translation

Step-by-step explanation:

The coordinates of points in pentagon FGHIJ are F(-2, 0), G(-1, 3), H(-2, 4), I(-5, 4), J(-4, 1)

The coordinates of points in pentagon F'G'H'I'J' are F'(2, 1), G'(3, 4), H'(2, 5), I(-1, 5), J(0, 2)

Therefore the series of transformations that moves pentagon FGHIJ onto pentagon F'G'H'I'J' are;

1) A horizontal translation 4 units to the right and

2) A vertical translation 1 unit up

Therefore, the series of transformations that moves pentagon FGHIJ onto pentagon F'G'H'I'J' is T₍₄, ₁₎ which is a translation, translation.

Two sides of an acute triangle are 8 and 15. how many possible lengths are there for the third side, if it is a positive integer

Misha Larkins [42]

In an accute triangle the 3 angles are less than 90°.

The minimum lenght of the third side is if the other two sides form the lowest possible angle (close to 0 degrees), in which case the length approximates to zero, so if the number is an integer, the minimum length of the fhird side is 1.

The maximum length of the third side is if it is close to the hypotenuse of a right triangle with legs 8 and 15 =>

hypotenuse^2 = 15^2 + 8^2 = 289 => hypotenuse =17. So, the lenght of the third side must be less than 17.

So, the possible lengths of the third side are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, and 16.

12-2x = -2(y-x) find x pls show me how u did it lol

EastWind [94]

Answer:

$12-2x = -2(y-x)$

$12-2x = -2y + 2x$

$12 + 2y = 4x$

$x = \frac{12 + 2y}{4}$

$x = \frac{6 + y}{2}$

Marcie cooked dinner for herself. The original recipe has a serving size of 3 and requires three and three sevenths pounds of ch

Sati [7]

Using proportions, the number of pounds that will be needed for a single serving is: one and three seventh pounds.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

The number of pounds for 3 people is given by:

$3 \frac{3}{7} = 3 + \frac{3}{7} = \frac{24}{7}$

Hence, for one person, the number of pounds can be divided by three(multiplied by 1/3), hence:

$\frac{24}{7} \times \frac{1}{3} = \frac{24}{21}$

24 divided by 21 has a quotient of 1 and remainder of 3, hence as a mixed number, the amount is:

one and three seventh pounds.
