Triangle ABC undergoes a transformation using the rule (x,y) → (x + 7. y + 3) to form triangle A'B'C'. Determine if ABC is
congruent to A'B'C'. Explain your reasoning.

Answers

Answer:

ΔABC and ΔA'B'C' are congruent, by the SSS rule of congruency

Step-by-step explanation:

The given parameters are;

The transformation undergone by triangle ABC = (x, y) → (x + 7, y + 3) to give triangle A'B'C'

Therefore, the points on triangle ABC are transformed by a translation of 7 units to the right and 3 units up to form triangle A'B'C'

Given that a translation transformation is a form of rigid transformation, we have;

The lengths of triangle ABC are congruent to the lengths of the sides of triangle A'B'C'

Therefore. ΔABC ≅ ΔA'B'C', by the Side-Side-Side (SSS) rule of congruency.

I need help with this problem on homework

Answers

The side given is 110*, and the side underneath that is 90*. If you add it together, That's 200*. Due to the sum property of a quadrilateral, we know that the angles must add up to 360* in total. So, we can simplify it as following.

(2x) + (x+10) = 360-200

2x + (x+10) = 160

2x + x = 160-10

2x + x = 150

x = 50

A bowl with 2 cups of flour in it weighs 405 grams. When it has 5 cups of flour in it, it weighs 765 grams. How much does the bowl weigh by itself?

Answers

Answer:

im think the bowl weighs 49.5 grams by itself

Step-by-step explanation:

405/2= 202.5

765/5=153

202.5-153=49.5

9514 1404 393

Answer:

  165 grams

Step-by-step explanation:

We can write an equation for the total weight (y) as a function of the number of cups of flour (x). The y-intercept of that equation will be the weight of the bowl.

The two-point form of the equation of a line is ...

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

The two points we are given are (2, 405) and (5, 765).

  y = (765 -405)/(5 -2)(x -2) +405

  y = 360/3(x -2) +405 . . . . simplify a bit

  y = 120x -240 +405 . . . . . eliminate parentheses

  y = 120x +165 . . . . . . . . . . combine terms

The bowl by itself weighs 165 grams.

Each cup of flour weighs 120 grams.

Solve and show your work below: Julie And Paulo are building a treehouse. Julie has a wood board that is 1.15 meters long and Paulo has a board that is 0.7 meter long.What is the total length of the two boards ? Solve this problem any way you choose .

Answers

Answer: Total length of the two boards= 1.85 meters

Step-by-step explanation:

Given: For a treehouse

Length of first wooden board =  1.15 meters

Length of second wooden board = 0.7 meters

Then by using the addition operator

Total length = Length of first board  + Length of second board

= 1.15 + 0. 7 meters

= 1.85 meters

Hence, the total length of the two boards = 1.85 meters

what is the y and x intercept of 15x + 20y =1800?​

Answers

You can do this by doing 1800 / 15 which is 120 and 1800 / 20 which is 90
Which means that the x intercept is 120 and the y intercept is 90.
For the y-intercept equation, the x will always be 0. And vice versa.

20y = 1800
Divide by 20 on both sides

y = 90

15x = 1800
Divide 15 on both sides

x = 120

Answers

the area of a rectangle is length times width or base times height

so 5 times 2x-3

there is no value of x

Sorry this got to you super late. At least others looking for the answer can find it.

The proof by S A S congruence rule is given below.

Given from fig, JK || LM.

And JK = LM

Since JK is parallel to LM and JN is a transversal so the angle made on the same side of JN are corresponding angles which are equal to each other.

So, angle KJL = angle MLN........equation 1

Also given L is the midpoint of JN so, JL = NL.....equation 2

Now, in triangle JLK and triangle LNM

JK = LM (given)

angle KJL = angle MLN (from 1)

JL = NL (from 2)

So by S A S congruence rule, triangle JLK conguent triangle LNM proved.
