Answer:
slope = -
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 9, - 4) and (x₂, y₂ ) = (- 3, - 6)
m = = = -
Answer:
3 pieces that are 1/2 units long,
6 pieces that are 1/4 units long,
or 12 pieces that are 1/8 units long.
Step-by-step explanation:
Multiplying these fractions respectively makes a fraction that is 1 ½ units long
108 degrees
B - Alternate angles
We have an equation: (5+b)/2 = 5
⇒ 5+b= 5*2
⇒ 5+b= 10
⇒ b= 10-5
⇒ b= 5
Final answer: b=5~
Answer:
Square
Step-by-step explanation:
Take a look at the attachment below. We need to apply the distance formula to derive the distance between points (0, 3), (3, 0), (0, - 3), (-3, 0). We can right away note that the sides of the quadrilateral created from these points are congruent. How so?
Again, taking a look at the attachment, you will see that this quadrilateral is named. Take side AB as an example. It forms a right triangle with the x and y - intercepts, the legs of lengths 3 and 3 units. AB is the hypotenuse. Respectively sides BC, CD, and AD each are the hypotenuse of their own mini triangle with legs of 3 units each! From this we can conclude that, by Pythagorean Theorem, AB = √18 = BC = CD = AD.
All sides are congruent, so the shape must be a square!
