Answer:

The correct statements are:

Step-by-step explanation:

A square is a type of parallelogram, which is a special quadrilateral. This quadrilateral has equal side length and interior angles measure 90∘. Every square is a parallelogram.

A quadrilateral is a four-sided polygon with four angles. The most common types are the parallelogram, rectangle, square, trapezoid, and the rhombus.

A trapezoid is a type of quadrilateral. A quadrilateral with exactly one pair of parallel sides is called a trapezoid.

Write the equation of the line in fully simplified slope-intercept form.
fiasKO [112]

y = -\frac{1}{2}x - 1

Step-by-step explanation:

Let's pick two points on the line: P_1(-4, 1) and P_2(2, -2). Let's calculate the slope of this line using these points:

m = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{-2 - 1}{2 - (-4)} = -\dfrac{1}{2}

With this value of the slope, we can write the general slope-intercept form of the equation as

y = -\frac{1}{2}x + b

To solve for the y-intercept b, let's use either P1 or P2. I'm going to use P2:

-2 = -\frac{1}{2}(2) + b \Rightarrow b = -1

Therefore, the slope-intercept form of the equation is

y = -\frac{1}{2}x - 1

For the equation y= x + 5, find the value of y when
Nina [5.8K]

Answer:

a) 3 b) 5 c) 7 d) 9

Step-by-step explanation:

For this, you want to replace x in the equation y=x+5 with each of the values listed.

For the first one, -2, the equation becomes y=-2+5, which is solved to y=3.

For the second one, 0, the equation becomes y=0+5, which is solved to y=5.

For the third one, 2, the equation becomes y=2+5, which is solved to y=7.

For the last one, 4, the equation becomes y=4+5, which is solved to y=9.

The sets of numbers 3, 4, 5 and 5, 12, 13 are examples
Wewaii [24]

Answer:

  • 8, 15, 17 — yes
  • 15, 20, 25 — yes
  • 20, 48, 52 — yes
  • 2, 9, 11 — no
  • 39, 80, 89​ — yes

Step-by-step explanation:

The squares of the three numbers in each of the given triples are listed. When the sum of the first two numbers is equal to the third, the set of numbers in the triple is a Pythagorean triple.

  {64, 225, 289}, yes

  {225, 400, 625}, yes — a 3,4,5 triple multiplied by 5

  {400, 2304, 2704}, yes — a 5,12,13 triple multiplied by 4

  {4, 81, 121}, no*

  {1521, 6400, 7921}, yes.

___

* the smallest set of integers that is a Pythagorean triple is {3, 4, 5}. The number 2 in this group tells you this cannot be a PT.
