12x = 40.8 find the number for the variable
4.3
3.4
4.4
489.6
Answer:
3.4
Step-by-step explanation:
Equation:
12x = 40.8
Isolate the variable:
x = 40.8/12
x = 3.4
Answer:
x = 3.4
Step-by-step explanation:
12x = 40.8
40.8 / 12 = 3.4
x = 3.4
Suppose m is the line with equation y = −4 and ΔA'B'C is mapped to ΔA"B"C" by applying the glide reflection T3, 0 Rm.
What are the coordinates of ΔA″B″C″?
Answer:
The coordinates of ΔA''B''C'' are;
A''(-1, -3), B''(-2, -6), C''(1 , -7)
Step-by-step explanation:
A glide reflection involves the reflection of the preimage over a given line, followed by the translation of the resulting image along the given line
Given that the coordinates of the triangle ΔA'B'C' are;
A'(-4, -5), B'(-5, -2), C'(-2, -1), we have by reflection across the line y = -4
A''(-4, -4 + 1) = A''(-4, -3)
B''(-5, -4 - 2) = B''(-5, -6)
C''(-2, -4-3) = C''(-2, -7)
Translation of A''B''C'' by T 3, 0, we have;
A''(-4, -3) → T₃, ₀ → A''(-4 + 3, -3) = A''(-1, -3)
B''(-5, -6) → T₃, ₀ → B''(-5 + 3, -6) = B''(-2, -6)
C''(-2, -7) → T₃, ₀ → C''(-2 + 3, -7) = C''(1 , -7)
The coordinates of ΔA''B''C'' are therefore;
A''(-1, -3), B''(-2, -6), C''(1 , -7).
Answer:
A″(−1, −3), B″(−2, −6), C″(1, −7)
option A

how are translations described mathematically
Answer:
In geometry, a translation is the shifting of a figure from one place to another without rotating, reflecting or changing its size. This is done by moving the vertices of the figure the prescribed number of spaces on a coordinate plane and then drawing the new figure.

Answer:
{ (-441/23, 433/23) }
Step-by-step explanation:
The "cross-multiplication method" is usually shown as follows:
1. rewrite the equations in general form: ax +by +c = 0
2. write the coefficients in two row in the order b, c, a, b.
3. form three products, each being the number in the first row times the number to its right in the second row. That is, b1·c2, c1·a2, a1·b2
4. form three more products, each being the number in the second row times the number to its right in the first row. That is, b2·c1, c2·a1, a2·b1
5. form three differences, subtracting the products of step 4 from those of step 3. Call these differences d1, d2, d3. (For example, d1=b1c2-b2c1.)
6. The values of x and y satisfy the equations ...
x/d1 = y/d2 = 1/d3
which is to say, ...
x = d1/d3, and y = d2/d3
_____
For your equations, we can rewrite them as ...
11x +12y -15 = 012x +11y +23 = 0Then our rows of coefficients are ...
[tex]\begin{array}{cccc}12&-15&11&12\\11&23&12&11\end{array}[/tex]
And our differences are ...
d1 = 12(23) -11(-15) = 441
d2 = -15(12) -23(11) = -433
d3 = 11(11) -12(12) = -23
The relations between x and y are ...
x/441 = y/-433 = 1/-23
so, x = -441/23 and y = 433/23
The solution set is one ordered pair: { (-441/23, 433/23) }.

The final solution is identical to the formula arrived at using Cramer's Rule. Calling this the "cross-multiplication method" avoids any discussion of matrices and determinants.
Which equation represents the line that passes through (–6, 7) and (–3, 6)?

y = –y equals negative StartFraction one-third EndFraction x plus 5.x + 5
y = –3x – 11y
y = –3x + 25
Answer:
y = - [tex]\frac{1}{3}[/tex] x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m= [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 6, 7) and (x₂, y₂ ) = (- 3, 6)
m = [tex]\frac{6-7}{-3+6}[/tex] = [tex]\frac{-1}{3}[/tex] = - [tex]\frac{1}{3}[/tex] , thus
y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 3, 6 ), then
6 = 1 + c ⇒ c = 6 - 1 = 5
y = - [tex]\frac{1}{3}[/tex] x + 5 ← equation of line

Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
These type of problems could be a little tricky so I'll explain this one as I go.
So the first step I would do is to multiply the 8 in both sides so you end up with...[tex]x+11=-24[/tex]
After that it should be easier and you'll go at it normally by subtracting the 11 in both sides and that should leave you with the answer of [tex]x=-35[/tex]
Two cables, with lengths of 40 feet and 35 feet, are tied from the top of a pole to stakes in
the ground. If the stakes are 30 feet apart, find the height of the pole.
Answer:
The height of the pole is 33.89 feet.
Step-by-step explanation:
Since the length of the cables are 35 feet and 40 feet respectively, the 40 feet cable being farthest from the pole. We know that they are 30 feet apart. This forms a scalene triangle in which the angle between the 40 feet cable and the distance apart of the cables ( or ground) is the angle of elevation of the pole from the 40 feet cable.
So, we use the cosine rule to find this angle of elevation. So,
b² = a² + c² - 2accosB where a = 40 feet , b = 35 feet, c = 30 feet and B = angle of elevation of top of pole from 40 feet cable.
cosB = (a² + c² - b²)/2ac
cosB = (40² + 30² - 35²)/(2 × 40 × 30)
cosB = (1600 + 900 - 1225)/2400
cosB = 1275/2400
cosB = 0.53125
B = cos⁻¹(0.53125)
B = 57.9°
Since we now have the angle of elevation of the top of the pole from the 40 feet cable, we now find the height h of the pole from
sinB = h/40 since the 40 feet cable, the ground and the pole form a right-angled triangle.
h = 40sinB
h = 40sin57.9°
h = 40 × 0.8472
h = 33.89 feet
So, the height of the pole is 33.89 feet.

-1+30x+24=6(5x+4)
???
Answer:
No solution.
Step-by-step explanation:
Write the expression, combine like terms, and distribute.
-1+30x+24=6(5x+4)
30x+23=30x+24
Get rid of the variable first because they're both 30x (it makes it a lot easier).
30x+23=30x+24
-30x -30x
23=24
23 is not equal to 24. When this happens, it means there is no solution, and that's just the answer.

Maria's dinner bill is $21.89 after tax. If she wants to leave a 15% tip, what will the total cost of the dinner be?
Please Answer
Answer:
Step-by-step explanation:
The answer would be, 25.17.
You need to multiple the total by 0.15 . Then add the answer to the total.
Answer:
$25.17
Step-by-step explanation:
$21.89 multiplied by 0.15 equals $3.28.
You then add the original bill to $3.28 which equals $25.17 for the total cost.
what kind of sequence is this?
-117, -114, -110, -105,...
Answer:
Finite
Step-by-step explanation:
When the sequence goes on forever it is called an infinite sequence,
otherwise it is a finite sequence
Examples:
{1, 2, 3, 4, ...} is a very simple sequence (and it is an infinite sequence)
{20, 25, 30, 35, ...} is also an infinite sequence

• commutative property
• addition property of equality
• 2x=8
• distributive property
• division property of equality
• x=4
• multiplication property of equality
• subtraction property of equality
Answer:
See below
Step-by-step explanation:
[tex]2(x+5)-3 =15[/tex]
Using the distributive property in the LHS we get
[tex]2x+10-3 =15[/tex]
[tex]2x+7=15[/tex]
Now add -7 both sides. So we have the subtraction property of equality.
[tex]2x+7+(-7)=15+(-7) \text{ This is what I meant for add}[/tex]
[tex]2x+7-7=15-7[/tex]
[tex]2x=8[/tex]
Now divide both sides by 2. So we have the division property of equality
[tex]\dfrac{2x}{2} =\dfrac{8}{2}[/tex]
[tex]x=4[/tex]
Answer −9
x + 1 = −80
Brainlist included
Answer:
x=9
Step-by-step explanation:
-9x+1=-80
To eliminate the one, you subtract one from both sides.
That gives you:
-9x=-81
Then you divide both sides by negative nine to get x by itself.
x=9
Which number is equivalent to the fraction 15/7? 2
2 1/7
7/15
1 8/7
Answer:
2 1/7
Step-by-step explanation:
Answer:
2 1/7, is 15/7(improper fraction) as a mixed fraction, and
1 8/7 is an improper mixed fraction equivilent to 2 1/7.
Step-by-step explanation:
15/7 = 7/7 + 7/7 + 1/7 = 1 + 1 + 1/7 = 2 1/7
1 8/7 = 1 + 8/7 = 1 +7/7 + 1/7 = 1 + 1 + 1/7 = 2 1/7
