Answer 1
Answer:

Answer:

  see below

Step-by-step explanation:

The sequence of letters in a congruence statement is important: it tells you the corresponding parts.

A triangle, such as ΔCAT, is named using the names of its vertex points. When it is said to be congruent to ΔDOG, it means these correspondences (and congruences) exist:

  • angle C to angle D . . . . . first letters correspond
  • angle A to angle O . . . . . second letters correspond
  • angle T to angle G . . . . . third letters correspond
  • segment CA to segment DO . . . . . named by 1st & 2nd letters
  • segment AT to segment OG . . . . . named by 2nd & 3rd letters
  • segment CT to segment DG . . . . . named by 1st & 3rd letters

Only one of these is on your list of answer choices:

  m∠A = m∠O

Which statement is true about the graphs shown? A) Only graph A represents a proportional relationship. B) Only graph B represents a proportional relationship. C) Graph A and graph B both represent a proportional relationship. D) Graph A and graph B both represent a non-proportional relationship.

Answers

Answer:

I believe the answer is B.

Step-by-step explanation:

Because a proportional relationship is one where x is proportional (equal) to y, and Graph A does not fall into that category, and Graph B does, the answer should be B.

Answer:

The answer A

Step-by-step explanation:

Only graph A represents a proportional relationship.

Two quantities are proportional to each other if the graph is a straight line through the origin.

What is -24 feet per 2 seconds as a unit rate in feet per seconds

Answers

All you have to do is divide -24 by two to get a unit rate, which means that you are move at a speed of -12 feet per second

At the movies, Liz eats 1/4 of a box of popcorn. Her friend Kyra eats 2 times a small much as Lizard eats. How much of a box of popcorn does Kyra eat?

Answers

Kyra ate 1/4 of the box of popcorn because 2 x 1/4 = 2/4 or 1/2. Hope this helps
Kura ate 2/4 or 1/2 of the popcorn because 2 times 1/4 is 2/4

What are the solutions to the system of equations?

Answers

Answer:

A. (1,5) and (5,13)

Step-by-step explanation:

We have been given a system of equations. We are asked to find the solution of our given system.

\left \{ {{y=x^2-4x+8}\atop {y=2x+3}} \right.

Equate both equations:

x^2-4x+8=2x+3

x^2-4x-2x+8-3=2x-2x+3-3

x^2-6x+5=0

Split the middle term:

x^2-5x-x+5=0

x(x-5)-1(x-5)=0

(x-5)(x-1)=0

Use zero product property:

(x-5)=0\text{ (or) }(x-1)=0

x=5\text{ (or) }x=1

Now, we will substitute both values of x, in our given equation to solve for y.

y=2x+3

y=2(1)+3

y=2+3

y=5

One solution: (1,5)

y=2x+3

y=2(5)+3

y=10+3

y=13

2nd solution: (5,13)

Therefore, option A is the correct choice.

Answer:

A

Step-by-step explanation:

Given the 2 equations

y = x² - 4x + 8 → (1)

y = 2x + 3 → (2)

Since both express y in terms of x we can equate the left sides, that is

x² - 4x + 8 = 2x + 3 ( subtract 2x + 3 from both sides )

x² - 6x + 5 = 0 ← in standard form

(x - 1)(x - 5) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

x - 5 = 0 ⇒ x = 5

Substitute these values into (2) for corresponding values of y

x = 1 : y = (2 × 1) + 3 = 2 + 3 = 5 ⇒ (1, 5)

x = 5 : y = (2 × 5) + 3 = 10 + 3 = 13 ⇒ (5, 13)

Solutions are (1, 5) and (5, 13)
