What is the image point of (4,5)(4,5) after a translation left 5 units and down 3 units?

Answers

Answer:

The image of point (-1,2)

Step-by-step explanation:

Step(i):-

Given point ( 4,5)

The Horizontal translation left '5' units then the transformed to

(x ,y ) → (x - 5 ,y)

(4,5)→ (4-5 , 5)

Step(ii):-

Again the vertical translation down '3' units then transformed to the co-ordinate point is  (x, y)→ ( x, y-3)

                       (4-5 , 5)→ ( 4-5 , 5 -3)

                      (-1 , 5) → (-1 , 2)

Final answer:-

The image of point (-1,2)

Check all the true statements.

Answers

Answer:

The true statements are:

2DE = AC1/2AC = DEDE || AC  

Step-by-step explanation:

As we are given,

AD = 3.5 and BD = 3.5

CE = 3 and BE = 3

From the given triangle ΔABC, it is clear that:

The segment DE bisects the sides AB and BC, so

AD = BD

CE = BE

It is clear that the segment DE is parallel to the segment AC, thus

DE || AC  

As DE is the midsegment between AB and BC, so

2DE = AC

1/2AC = DE

Thus, the true statements are:

2DE = AC1/2AC = DEDE || AC

Is there a way to quickly find a function if you have a handful of ordered pairs?
ex. (-6, 10) (-4, 7) (-2, 4) (0, 3) (2, 0) (4, -3)

Answers

Yeah. You basically have to look at every x value and see if for every x value, is there ONLY one y-value. So in your example, it is a function because every x value has only one y value. Let’s say you had (1,3) and (1,5). That would not be a function because the x value of 1 has TWO y values (3 and 5), therefore it is not a function.

That’s how you can easily spot if something is a function by just looking at a handful of ordered pairs. I hope this makes sense.

Step-by-step explanation:

Given function:

g(t) = 3t² - 5t + 4

a)  g(2)

g(2) = 3*2² - 5*2 + 4 =          3*4 - 10 + 4 =          12 - 6 =          6

b)  g(t - 2)

g(t - 2) = 3(t - 2)² - 5(t - 2) + 4 =               3(t² - 4t + 4) - 5t + 10 + 4 =               3t² - 12t + 12 - 5t + 16 =               3t² - 17t + 28

c)  g(t) - g(2)

g(t) - g(2) = 3t² - 5t + 4 - 6 =                   3t² - 5t - 2

Your next Pre-Algebra test is worth 93 points and contains 38 multiple choice and short answer problems. Each
multiple choice problem is worth two points and each short answer is worth three points. How many of each type of
problem is on the test?

Answers

Answer:

There are 21 multiple-choice problems and 17 short answers.

Step-by-step explanation:

Let there are x multiple-choice problems and y short answers.

ATQ,

x+y = 38 ....(1)

Each  a multiple-choice problem is worth two points and each short answer is worth three points.

2x+3y = 93 ....(2)

Multiply equation (1) by 2.

2x+2y = 76 ....(3)

Subtract equation (2) and (3) we get :

2x+3y-(2x+2y) = 93-76

2x+3y-2x-2y = 17

y=17

Put the value of y in equation (1).

x+17 = 38

x=21

Hence, there are 21 multiple-choice problems and 17 short answers
