John says the transformation rule (x, y) Right-arrow (x + 4, y + 7) can be used to describe the slide of the pre-image (4, 5) to the image (0, –2). What was his error?

Answers

sample response: The pre-image is the point you start with. To check the transformation rule, substitute the values of the coordinates (4, 5) into the rule. You get (4, 5) → (4+4, 5+7). Simplify to get (4, 5) → (8, 12). This is the image. Instead the rule was applied to the image. This is the source of the error.

Answer:

The transformation rule should be applied to the pre-image.  The application of the rule results in the point (8, 12).  The transformation rule was applied to the wrong point.

3x - 2y = 24
x + 2y = 48
X =
Hy=
v

Answers

Answer:

x = 18 , y = 15

Step-by-step explanation:

Given the 2 equations

3x - 2y = 24 → (1)

x + 2y = 48 → (2)

Adding the 2 equations term by term will eliminate the y- term

4x + 0 = 72

4x = 72 ( divide both sides by 4 )

x = 18

Substitute x = 18 into either of the 2 equations and solve for y

Substituting into (2)

18 + 2y = 48 ( subtract 18 from both sides )

2y = 30 ( divide both sides by 2 )

y = 15

Step-by-step explanation:

Number of games = 4

Number of controllers = 2

Mr. Gutierrez and his brother want to purchase a game console that is $300.

Let [tex]x[/tex] denotes number of games and [tex]y[/tex] denotes number of controllers.

[tex]4x+2y=300[/tex]

Can you pls show me the solving steps and the answer I have to type a paper on how to solve this problem help me plsss (10 points)

Answers

Answer:

x= 21/15

if you need to reduce it would be x=7/5

Step-by-step explanation:

12x-15 =6-3x

add 3x to both sides

15x- 15 = 6

now add 15 to both sides

15x = 21

lastly divide both sides by 15

x= 21/15

if you need to reduce it would be x=7/5

Answer:

x = 7/5 or 1.4

Step-by-step explanation:

12x - 15 = 6 - 3x             Need to move one variable term to the other side to

+3x              + 3x         isolate it on one side

---------------------------

15x - 15 = 6                   need to +15 to isolate the variable term

     +15   +15

-----------------------

15/15x = 21/15 (simplify 21/15 = 7/5)   need to divide by 15 to isolate x

------------------------

x = 7/5 or 1.4

PLS HELP FOR 20 POINTS PLEASE THIS IS HARD (i think 20 i dont know i set it to 20 but who knows im new to this) sorry for talking to yall like you know humans and not people on internet

Answers

Answer:

30 feet

Multiply

For every 1 mm on the map there are 200 miles of actual distance (third option)

8 cm, 26.8 cm, and 58 cm (last option)

Step-by-step explanation:

Question 1:

An airplane is 180 feet long. Blake makes a scale model of the airplane at 1:60  of its actual size how long is the model?

If the model is scaled down by 1/60, then the model is 60 times smaller than the actual airplane. Set the model size as "x" and so we can write this ratio.

1 / 60 = x / 180

Cross multiply (multiply 60 and x, and 180 and 1)

60x = 180

x = 3 feet

Question 2:

To produce an enlarged or reduced measure you ____ the scale.

In order to find the measure, you multiply it by the scale factor.

Question 3:

A scale on a map is 1 mm: 200 miles

The question tells us that for every 1 mm, there are actually 200 miles. So the answer is the first option, For every 1 mm on the map there are 200 miles of actual distance.

Question 4:

What are the new dimensions if we expand the triangle below by a factor of 4.

If we multiply by the scale factor, 4, we get

2 * 4 = 8

6.7 * 4 = 26.8

14.5 * 4 = 58

Thus, the answer is 8 cm, 26.8 cm, and 58 cm (last option)

I hope this helps! Feel free to ask any questions!
