PLS HELP ME 12x - 15 = 6 - 3x
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)
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

Which of the rules given below shows the transformation of f?
OA g(x) = f(x) - 4
O B. g(x) = fx-4)
OC.
g(x) = f(x + 4)
OD. g(x) = f(x) + 4
Answer:
A.) g (x) = f (x) - 2
Step-by-step explanation:
The first thing we are going to do in this case is to take into account the following definition.
Translations are transformations that change the position of the graph of a function.
The general shape of the graph of a function is moved up, down, to the right or to the left.
The translations are considered rigid transformations. Now we will see how these are performed.
Vertical translations:
Suppose that k> 0
To graph y = f (x) + k, move the graph of k units up.
To graph y = f (x) -k, move the graph of k units down.
Using the definition we conclude that:
g (x) = f (x) - 4
Two exponential functions, fand g, are shown in the figure, where g is a transformation of f, g (x) = f (x) - 4 equation shows transformation of f. The correct option is A.
What is exponential function?A mathematical function of the form [tex]f(x) = a^x[/tex], where an is a positive constant and x is the input variable, is an exponential function.
The characteristic curve of exponential functions rises or falls rapidly depending on whether an is greater or less than 1.
To determine the transformation of f which gives g, we need to examine how f has been transformed to obtain g.
Looking at the graph, we can see that g is a vertical shift of f. Specifically, g is obtained by shifting f downward by 2 units. Therefore, we need a rule that subtracts 2 from f (x) to get g (x).
Out of the given options, the only one that matches this description is:
g (x) = f (x) - 4
Option A subtracts 4 from f (x), which is not what we observe in the graph. Option B uses an incorrect format and is also subtracting 4 from f (x).
Option C adds 4 to x, which would result in a horizontal shift, not a vertical shift.
Therefore, the correct answer is A g (x) = f (x) - 2.

Answer:
67.9
Step-by-step explanation:
The polygon has 6 sides.
Sum if interior angles = (n-2)180
=(6-2)180
= 4 x 180
= 720
A + B + C + D + E + F = 720
x+40 + 2x-9 + 2x + 2x + x + x+78 = 720
9x + 109 = 720
9x = 720-109
9x = 611
x = 611/9

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?
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.

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
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)

Use elimination to solve the system of equations. Enter your answers in the boxes.
3x - 2y = 24
x + 2y = 48
X =
Hy=
v
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
