2x-4=-4x+6
What value of x makes the equation true
A x=5/3
B x=-5/3
C x=5
D x=-5
Answer: 5/3
6x = 10
x=10/6
x=5/3
Answer:
x = 5/3
Step-by-step explanation:
2x-4=-4x+6
Add 4x to each side
2x+4x-4=-4x+4x+6
6x -4 = 6
Add 4 to each side
6x -4 +4 = 6+4
6x = 10
Divide each side by 6
6x/6 = 10/6
x = 5/3

Points A, B , and C are collinear. Point B is between A and C . Solve for x given the following. AC=22 AB=x+10 BC=x+14
Answer:
x = - 1
Step-by-step explanation:
The points A, B and C are collinear meaning they all lie on a line.
Thus
AB + BC = AC , substitute values
x + 10 + x + 14 = 22, that is
2x + 24 = 22 ( subtract 24 from both sides )
2x = - 2 ( divide both sides by 2 )
x = - 1

which law would you use to simplify the expression 3^10/3^4
Answer:
I would use the "quotient rule of exponents"
Step-by-step explanation:
I would use the "quotient rule of exponents" which states that to divide two exponents that have the same base, the result is the same base to an exponent which equals the subtraction of the exponent in the numerator of the original expression minus the exponent that base has in the denominator.
That is:
[tex]\frac{a^m}{a^n} =a^{m-n}[/tex]
Then in this case the simplified expression would be:
[tex]\frac{3^{10}}{3^4} =3^{10-4}=3^6[/tex]

Answer:
A polygon is a plane figure with at least three straight sides and angles, and typically five or more.
Step-by-step explanation:
When you flip a biased coin the probability of getting a tail is 0.75.
How many times would you expect to get tails if you flip the coin 160 times?
Answer:
You would expect to get tails 120 times
Step-by-step explanation:
0.75 * 160 = 120
Answer:
120
Step-by-step explanation:
to find the number of times, you expect to get tails:
multiply 160 by 0.75.
you could also multiply 160 by 3/4, which is easier, but still gives the same answer.
3/4 x 160 = 3 x 40 = 120

F(2) = -2 + 5 =3
Step-by-step explanation:
Given f(x) = -x + 5
g(x) = 2 x + 2
Put x=0 in f(x) = -x +5
f(0) = -0 +5 =5
g(x) = 2 x + 2
Put x= 1
g(1) = 2(1) +2
g(1) = 4
f(0) +g(1) = 5 +4 =9
b) f(x) = -x +5
put x = 2

1:750 scale model of the Sydney Opera House after a trip to Australia. The length of the model is 24.4 centimetrers. Find the actual length x (in meters) of the Sydney Opera House.
Answer:
183 meters
Step-by-step explanation:
A 1:750 scale model means that each cm on the model corresponds to 750 cm of the actual Sydney Opera House. If the model is 24.4 centimeters long, the actual Opera House has a length of:
[tex]x = 24.4*750\\x=18,300\ cm\\x=183\ m[/tex]
The actual length of the Sydney Opera House is 183 m.
Which statement explains the relationship of sides BA and B'A' after rectangle BADC has been rotated 90° clockwise about the origin?
coordinate plane with rectangle ABCD at A (3,5), B (1,3), C (5,-1), and D (7,1)
Side B'A' has a slope of −1 and is perpendicular to side BA.
Side B'A' has a slope of 1 and is parallel to side BA.
Side B'A' has a slope of 1 and is perpendicular to side BA.
Side B'A' has a slope of −1 and is parallel to side BA.
Answer:
Numbering the options, we have;
1) Side B'A' has a slope of −1 and is perpendicular to side BA.
2) Side B'A' has a slope of 1 and is parallel to side BA.
3) Side B'A' has a slope of 1 and is perpendicular to side BA.
4) Side B'A' has a slope of −1 and is parallel to side BA.
The correct option is;
1) Side B'A' has a slope of -1 and is perpendicular to side BA
Step-by-step explanation:
The given coordinates are;
A(3, 5) B(1, 3), C(5, -1) and D(7, 1)
The slope of BA is found as follows;
[tex]Slope \, of BA= \dfrac{y_{2}-y_{1}}{x_{2}-x_{1}} =\dfrac{3-5}{1-3}= \dfrac{-2}{-2} = 1[/tex]
Rotation of a line through 90 degrees gives
(x, y) will be (y, -x)
Therefore, the coordinates of A' = (5, -3)
The coordinates of B' = (3, -1)
Then the slope is given as follows;
[tex]Slope \, of \, B'A' =\dfrac{-1 -(-3)}{3-5}= \dfrac{2}{-2} = -1[/tex]
Therefore side B'A' has a slope of -1 and is perpendicular to side BA.
Option (4) will be the correct option.
Coordinates of the vertices of rectangle ABCD are,
A(3, 5), B(1, 3), C(5, -1) and D()Slope of a segment with endpoints [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the expression,
Slope 'm' = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Therefore, slope of segment BA (m₁) = [tex]\frac{3-5}{1-3}[/tex] = 1
If a point (h, k) is rotated 90° clockwise about the origin, rule to be followed,
(h, k) → (-k, h)
Following this rule,
B(1, 3) → B'(-3, 1)
A(3, 5)→ A'(-5, 3)
Slope of segment B'A' (m₂) = [tex]\frac{1-3}{-3+5}=-1[/tex]
Expression representing two segments with slopes [tex]m_1[/tex] and [tex]m_2[/tex] to be perpendicular,
[tex]m_1\times m_2=-1[/tex]
Since, slopes of two segments BA and B'A' are (1) and (-1).
(1) × (-1) = -1
Therefore, both the segments BA and B'A' will be perpendicular.
Option (4) will be the answer.

Which statement regarding the diagram is true?
m2WXY = m_YXZ
m2WXY < m_YZX
m2WXY + m2YXZ = 180°
m2WXY + m_XYZ = 180°
Explanation:
These two angles are a linear pair. They are supplementary (ie they add to 180) and they are adjacent. We know they are supplementary because line WXZ is a straight line. Put another way: point X is on line WZ.
-------
Side notes:
Choice A is only true if we have a 90 degree angle at point XChoice B is never true because of the remote interior angle theoremChoice D is only true if we have an isosceles triangle with XZ = YZ.The correct statement is,
⇒ m ∠WXY + m ∠YXZ = 180°
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
To find the correct statement.
Now, We can find the correct statement as;
By definition of linear pair we get;
⇒ m ∠WXY + m ∠YXZ = 180°
Thus, The correct statement is,
⇒ m ∠WXY + m ∠YXZ = 180°

The probability of a biased coin landing on heads is 2/7 complete the tree diagram
Answer:
The numbers needed to fill each box are in the image attached
Step-by-step explanation:
The probability of the coin landing on heads is 2/7, so the probability of it landing on tails is 1 - 2/7 = 5/7
The probability of landing heads 2 times is:
P = (2/7) * (2/7) = 4/49
The probability of landing heads and then tails is:
P = (2/7) * (5/7) = 10/49
The probability of landing tails and then heads is:
P = (5/7) * (2/7) = 10/49
The probability of landing tails 2 times is:
P = (5/7) * (5/7) = 25/49
The numbers needed to fill each box are in the image attached.
Step-by-step:
The first flip numbers will always add up to 1 so you do
1 - 2/7= 5/7
now it gets easy...
The second flip head will be 2/7 because it is a biased dice and the second flip tail will be 5/7
This also applies for the bottom 2: 2/7 head, 5/7 tails

find the midpoint of A and b where A has coordinates (2,7) and B has coordinates (6.3)
Answer:
Midpoint of A and B is (4,5).
Step-by-step explanation:
If there are two points (x1,y1) and (x2,y2) on the coordinate plane
then midpoint is given by (x1+x2)/2 , (y1+y2)/2
_____________________________________
here two points are (2,7) and (6,3)
substituting this value in (x1+x2)/2 , (y1+y2)/2
we have,
midpoint (2+6)/2, (7+3)/2
= 8/2 , 10/2 = 4,5
Midpoint of A and B is (4,5).
A person places $72300 in an investment account earning an annual rate of 7.1%, compounded continuously.

Our P is 72300; our r is .071, e is Euler's number (a constant) and t is 19 years. Filling in:
