[tex]4(3q - 2) = 16q[/tex]
Hey there!!
Given equation :
... 4 ( 3q - 2 ) = 16q
... 12q - 8 = 16q
Subtract by 12q on both sides
... -8 = 4q
Divide by 4 on both sides
... -8 / 4 = q
... q = -2
Given equation :
4 ( 3q - 2 ) = 16q
Substitute the value of -2 in place of q
... 4 ( -6 -2 ) = 16 × -2
... 4 ( -8 ) = -32
... -32 = -32
∴ Hence proved

If y = 7x, what happens to x when y is increased by 5 times its original value?
A) x decreases 5 times its original value
B) x increases to 11/5 its original value
C) x also increases 5 times its original value
D) x decrease to 4/5 of its original value
B) Because to find the value of x and y you have to divide x by 7 to make it x and the multiply 7 by y because you divided by the opposite side, which is x.
find x if a =13 and C = 47 need help
So you're using the Pythagorean theorem which is a^2 + b^2 = c^2... so if you dont have b you can manipulate the equation. That equation is c^2 - a^2= b^2, so you square 47 which is 2209 and then square 13 which is 169... you do 2209-169 and that equals 2040, then you do the square root of that which is 45.166359 that can be simplified to 45 or two decimal points 45.167. Hope that Helped! :)

Audrey is trying to find the equation of a line parallel to y = 2 over 3 x −5 in slope-intercept form that passes through the point (−6, −1). Which of the following equations will she use
Final answer:
To find the parallel line's equation, Audrey used the slope of 2/3 from the given line and the point (-6, -1) to write the equation in point-slope form, eventually simplifying it to y = 2/3x + 3.
Explanation:
Audrey is looking to find the equation of a line that is parallel to the line with the equation y = 2/3x - 5 and that passes through the point (-6, -1). Since parallel lines have the same slope, our new line will keep the slope of 2/3. Using the point-slope form of the equation of a line, we set up y - y1 = m(x - x1). Plugging in the known slope m and point (x1, y1), we get y - (-1) = 2/3(x - (-6)). After simplifying, we have y + 1 = 2/3x + 4. Finally, we solve for y by subtracting 1 from both sides, yielding the equation y = 2/3x + 3 as the line that is parallel to the original line and passes through the given point.

Leeann works 20 hours per week and makes $15 per hour. What is her yearly pay?! SOME ONE PLEASE HELP ME PLATO
(20 hrs/1 wk)*(15 dollars/1 hr) = 20*15 = 300 dollars per week
There are 52 weeks in a year. If Leeann works all 52 weeks (ie no sick days, vacations, etc) then,
(52 weeks/1 yr)*(300 dollars/1 week) = 52*300 = 15600
Her yearly pay is $15,600
Answer:
$15,600
Step-by-step explanation:
Leeann works 20 hours per week and makes $15 per hour
Her weekly income = 20 × 15 = $300
In one year = 52 weeks
Therefore, her yearly pay = 300 × 52
= $15,600
Leeann's yearly pay is $15,600
Reflectional symmetry is the quality a design has if it maintains _____ when it is reflected across an axis or line of symmetry. A. some characteristics B. all characteristics C. no characteristics
The correct answer would be B, all characteristics. Reflectional Symmetry is when an object is divided into halve in which to completely identical pieces are left.
(B) All characteristics.
Reflection symmetry:In mathematics, symmetry with regard to a reflection is known as reflection symmetry, line symmetry, mirror symmetry, or mirror-image symmetry. In other words, a figure with reflectional symmetry does not alter when it is reflected.There is a symmetry line or axis in 2D and a symmetry plane in 3D. A mirror-symmetric object or figure is one that is identical to its changed counterpart. In conclusion, the shape is divided in two by a line of symmetry, and both parts should be the same.Therefore, the correct option to fill the blank is (B) All characteristics.

twelve is the same as two-thirds a number diminished by two.
12 = 2/3(x - 3)
Distributive property.
12 = 2/3x - 2
Add 2 to both sides.
14 = 2/3x
Multiply both sides by 3.
42 = 2x
Divide both sides by 2.
21 = x
The value of x is equal to 21.
The equation, twelve is the same as two-thirds a number diminished by two - True
Explanation:To determine if twelve is the same as two-thirds of a number diminished by two, we can set up an equation. Let's represent the number as 'x.' According to the statement, twelve is equal to two-thirds of x diminished by two. Mathematically, this can be written as:
12 = (2/3)x - 2
To solve for x, we need to isolate it on one side of the equation. First, we can add 2 to both sides:
14 = (2/3)x
Next, we can multiply both sides by 3/2 to eliminate the fraction:
14 * (3/2) = x
21 = x
Therefore, the number in question is 21. To confirm, we can substitute x back into the original equation:
12 = (2/3)(21) - 2
12 = 14 - 2
12 = 12
Since the equation is true, we can conclude that the statement is True.

Complete the mapping of the vertices of ΔDEF. D(2, –4) → D' E(1, –1) → E' F(5, 1) → F' What is the rule that describes a reflection across the line y = x? rx = y(x, y) →
D(2, –4) → D' = (-4, 2)
E(1, –1) → E'= (-1, 1)
F(5, 1) → F'=(1, 5)
What is the rule that describes a reflection across the line y = x?
rx = y(x, y)= (y, x)
The rule which describes a reflection across the line is y(x, y) --> (y, x) and the mapping of the vertices of ΔDEF is (-4, 2)D', (-1, 1)E' , (1, 5)F'.
What is reflection?The reflection of a plane or shape is flipping the original figure with respect to a reference line.
The following steps are used to for reflecting a shape-
Select the shape which has to be reflected.Select a base line or reference line over which the shape has to be reflected.Mark the corners of the shape at the equidistant from the reference line as the original shape has, but in the opposite direction.The reflected shape is now is facing the opposite direction.The rule that describes a reflection across the line says that when your reflect a point across the line say y=x. Then the coordinates of x and y are interchanged as,
y(x, y) → (y, x)
Now let's complete the mapping of the vertices of ΔDEF using the above rule. For this, change the places of x and y coordinate as,
D(2, –4) → (-4, 2)D'
E(1, –1) → (-1, 1)E'
F(5, 1) → (1, 5)F'
Thus, the rule which describes a reflection across the line is y(x, y) --> (y, x) and the mapping of the vertices of ΔDEF is (-4, 2)D', (-1, 1)E' , (1, 5)F'.
