2(x + 3) = 6
2x + 3 = 6
- 3 - 3
2x = 3
+2 +2
x = 1.5
Answer:
Mistake is 2x + 3 = 6. It should be 2x + 6 = 6. Therefore x = 0
Step-by-step explanation:
2(x + 3) = 6
Expand the bracket:
2x + 6 = 6
Subtract 6 from both sides:
2x = 0
Divide both sides by 2
x = 0

The equation `2x - 3 = 4x + 3` is modeled above. What value of `x` makes the equation true?
4) The given figure shows ∆ABC. Points D,E and F are the mid-points of sides AB,AC and BC respectively. Sides AB, BC and CA measure 6 cm, 10 cm and 8 cm respectively. What is the area of ∆DEF? *
Answer:
the area of ∆DEF = 6 cm²
Step-by-step explanation:
The midpoint theorem states that the line segment connecting the midpoints of two sides of a triangle is parallel to the third side and is congruent to one half of the third side.
DE // BC and DE = BC/2 = 10/2 = 5
same reason: DF = AC/2 = 4
FE = AB/2 = 3
DF² + FE² = 16 + 9 = 25 = 5² = DE²
by the Pythagorean theorem, ΔDFE is a right triangle
area ΔDEF = (3 x 4) / 2 = 6 cm²

through: (-3,-5), parallel to y = 2x + 2
Answer:
y = 2x + 1
Step-by-step explanation:
Since you have an equation and a point, all you need to do is substitute the coordinates into the equation and then solve for the y-intercept (or "b"):
y = mx + b
y = 2x + 2
(-3, -5)
-5 = 2(-3) + b
-5 = -6 + b
-5 + 6 = b
b = 1
Now you have your final equation:
y = 2x + 1
*Remember that parallel lines have the same slope, so finding a new slope is not needed!

The graph of the absolute value parent function, fx) = [xl, is stretched
horizontally by a factor of 6 to create the graph of g(x). What function is g(x)?
O A. g(x) = (x+61
B. g(x) = 6] x1
O c. g(x) = \šal
D. g(x) = 16x1
Answer:
g(x) = [x/6]
Step-by-step explanation:
The given graph is f(x)=[x]
On stretching the function f(x) by a factor of 6, the new function g(x) is
g(x) = f(x/6)
So, g(x) = [x/6]
Hence, on stretching the f(x) by a factor of 6, the new function g(x)=[x/6].

A mail order company charges 4.5% for shipping and handling. If the total order is 54.34 how much was the order total before shipping? Write an equation
Answer:
$52
Step-by-step explanation:
Given that :
Amount charged for shipping and handling = 4.5%
Let cost of order = x
Total amount charged = 54.34
However,
total. Amount charged = (total cost + handling and shipping)
54.34 = x + 0.045x
54.34 = 1.045x
Order total before shipping = 54.34 / 1.045
Order total before shipping = 52

Step-by-step explanation:
Translate a point (x, y) 3 units left and 5 units up. Then translate the image 5 units right and 2 units up. What are the coordinates
of the point after the translations?
The coordinates are
Answer:
Please check the explanation.
Step-by-step explanation:
Given the point
P(x, y)
Please note that when we translate a point 'c' units left, the 'c' units are subtracted from the x-values, and when translating a point 'c' units right, we add the 'c' units to the x-values.
Also, note that when we translate a point 'c' units down, the 'c' units are subtracted from the y-values, and when translating a point 'c' units up, we add the 'c' units to the y-values.
After First Translation:
3 units left and 5 units up
P(x, y) → P'(x-3, y+5)
After Second Translation:
Translate the image 5 units right and 2 units up.
P'(x-3, y+5) → P''(x-3+5, y+5+2) = P''(x+2, y+7)
Thus, the coordinates of the point(x, y) after the translations are: P''(x+2, y+7)
TAKING AN EXAMPLE
Let us consider that point
P(0, 0)
After First Translation:
3 units left and 5 units up
P(0, 0) → P'(0-3, 0+5) = P'(-3, 5)
After Second Translation:
Translate the image 5 units right and 2 units up.
P'(-3, 5) → P''(-3+5, 5+2) = P''(2, 7)
Thus, the coordinates of the point P(0, 0) after the translations are:
P''(2, 7)Answer: P''(2, 7). (hope this is what you wanted)!

the function c(x)=18x-10 represents the cost in dollars. How many tickets can you buy?
Note: It seems you may have unintentionally missed writing the complete question. As total cost is missing.
So, I am assuming how many tickets Mr. XYZ can buy if he/she pays 188 dollars.
The solution would still clear your concept though.
Answer:
Please check the explanation.
Step-by-step explanation:
Given the function
[tex]c(x)=18x-10[/tex]
The slope-intercept form of the line equation
We know that the slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
so
comparing with the slope-intercept form of the line equation
here:
rate of change = 18 c(x) or y represents the costand
'x' represents the number of tickets
Assuming the total cost i.e. c(x) = $188
In order to determine the value of x, set c(x) = 188
i.e.
188 = 18x -10
switch sides
188x - 10 = 170
add 10 to both sides
18x - 10 + 10 = 188 + 10
18x = 198
Divide 18 to both sides
18x/18 = 198/18
x = 11
Therefore, if you can buy x = 11 tickets if you pay 170 dollars.
Find the equation in slope intercept form
(-8,-2) and (-4,6
Answer:
y = 2x + 14
Step-by-step explanation:
Answer:
y = 2x + 14
Step-by-step explanation:
Use the slope equation:
[tex]m = \frac{y2-y1}{x2-x1}[/tex]
[tex]m = \frac{6-(-2)}{-4-(-8)}\\m = \frac{8}{4}\\m = 2[/tex]
Next, find the y-intercept by subbing in one of the points and the slope into what you have so far in the equation:
(-8, -2)
y = mx + b
-2 = 2(-8) + b
-2 = -16 + b
-2 + 16 = b
b = 14
Now you have your final equation:
y = 2x + 14

Divya wants to rent a car to drive for the weekend. The rental company has a special that allows her to rent it for $200 for the weekend, plus $0.07 per mile. Divya only has $230. Write an inequality, solve, and determine her limitations when renting.
Answer:
[tex]200 + 0.07m \leq 230[/tex]
A maximum of [tex]\approx[/tex] 428 miles is the distance what Divya can travel.
Step-by-step explanation:
Given that:
Rent to be paid for the car in the weekend = $200
Charges to be paid per mile = $0.07
Total money available with Divya = $230
To find:
The inequality as per her limitations and solution to the problem.
Solution:
Let the number of miles for which Divya can drive = [tex]m[/tex] miles
Charges for one mile = $0.07
Charges for [tex]m[/tex] miles = $0.07[tex]m[/tex]
Total charges for renting and [tex]m[/tex] miles = Rental charges + Operational charges
Total charges for renting and [tex]m[/tex] miles = $200 + $0.07[tex]m[/tex]
These are charges must be lesser than equal to the amount of money available with Divya.
Therefore, we can write:
[tex]200 + 0.07m \leq 230[/tex]
Subtracting 200 from both the sides:
[tex]0.07m \leq 30[/tex]
Dividing both sides with 0.07:
[tex]m \leq \dfrac{30}{0.07}\\m\leq 428.6[/tex]
Therefore, a maximum of [tex]\approx[/tex] 428 miles is the distance what Divya can travel.

Given the following diagram, find the missing measure. m 4 = 2x°, m 2 = (4/3)x°, m 3 = 20°, find x. 10 30 20 60
Answer:
B. 30 degrees
Step-by-step explanation:
Find the diagram attached
From the diagram:
Interior angles are m<3 and m<2
Exterior angle = <4
using the rule that says that the sum of interior angles is equal to the exterior angle we have:
m<2+m<3 = m<4
(4/3)x°+20 = 2x°
multiply through by 3:
4x° + 60 = 6x°
4x°-6x° = -60
-2x° = -60
x°= -60/-2
x° = 30°
Hence the value of x is 30 degrees

Which facts could be applied to simplify this expression? Select three options.
(Negative 5 x minus 3 y) minus (negative x minus 3 z)
To subtract like terms, subtract the coefficients, not the variables.
Like terms are terms that contain the same variable, raised to the same power.
The simplified expression is Negative 6 x minus 3 y + 3 z.
The simplified expression is Negative 4 x minus 3 y + 3 z.
Negative (negative x) is equivalent to Negative x, so Negative 5 x minus x = negative 6 x
Answer:
Negative 4 x minus 3 y + 3 z.
Step-by-step explanation:
We need to simplify the given expression : (-5x-3y)-(-x-3z)
Here, x,y and z are variables.
Combining like terms, we get :
(-5x-3y)-(-x-3z) = (-5x-3y)+x+3z
= (-5x+x)-3y+3z
= -4x-3y+3z
Hence, the equivalent expression is -4x-3y+3z. Hence, the correct option is (b) "The simplified expression is Negative 4 x minus 3 y + 3 z".
