find the value of x
a. 124
b. 50
c. 93.5
d. 32
==============================================
Explanation:
The chords intersect to form the angle 73 degrees. The chords also form the arcs of 96 and x. Averaging the arc measures will result in the internal angle 73
---------
(x+96)/2 = 73
x+96 = 2*73 ... multiply both sides by 2
x+96 = 146
x = 146-96 ... subtract 96 from both sides
x = 50

Determine whether a triangle can be formed with the given side lengths. If so, use Heron's formula to find the area of the triangle. (5 points) a = 240 b = 123 c = 207
Answer:
Triangle inequality rule states that the sum of eachpair of sides must be greater than the third sides.
240 + 123 > 207 true
240 + 207 > 123 true
123 + 207 > 240 true
A = √(s(s-a)(s-b)(s-c))
s is the semi-perimeter (a + b + c)/2
s = (240 + 123 + 207)/2
s = 285
A = √(285*(285-249)(285-123)(285-207))
A = 12,730 units^2

Which of the following statements are true about segments in a plane? Choose all that apply.
Every segment has infinitely many midpoints
Every segment has two bisectors
Every segment has one perpendicular bisector
Every segment has infinitely many congruent segments
Every segment has one line that is perpendicular to it
Answer:
Every segment has infinitely many midpoints
Every segment has one perpendicular bisector
Every segment has infinitely many congruent segments
Every segment has one line that is perpendicular to it
Step-by-step explanation:
Segments in a plane: The term "segment" is determined as a specific part that is being cut-out from a particular figure, for example, a spherical or a circular figure through a plane or a line as one of the parts consisting of a "circular area" associated with an arc or its related chord by two distinct planes or lines.

Explain why you cannot find the intersection points of the two lines shown below. Give both an algebraic reason and a graphical reason. y=4x+1 and y= 4x+10
Answer:
[tex]m_1 = m_2 = 4[/tex]
Step-by-step explanation:
Given
[tex]y = 4x + 1[/tex]
[tex]y = 4x + 10[/tex]
Required
Show that these two lines have no point of intersection
The general equation of a line is
[tex]y = mx + b[/tex]
Where m represents slope
In [tex]y = 4x + 1[/tex]
[tex]m = 4[/tex]
Similarly; in [tex]y = 4x + 10[/tex]
[tex]m = 4[/tex]
Since the slope of both lines are equal;
[tex]m_1 = m_2 = 4[/tex]
This implies that the lines are parallel and parallel lines have no point of intersection

Which statement is true? Integers are always whole numbers or all whole numbers are rational or integers include all rational members or rational numbers do not include integers.
Let's go through each statement to see if it is true or false.
=====================================
Integers are always whole numbers
This is true. Integers are numbers that don't have any fractional or decimal portion
=====================================
All whole numbers are rational
This is also true. Let's say we had the whole number 7. We can write it as 7/1 which is rational. A rational number is any number that can be written as a fraction of two integers. So this means any whole number can be converted to a rational number format.
=====================================
Integers include all rational members
This is false. It is true that all integers are rational, but there is more to the story than just integers when it comes to listing all rational numbers.
For instance, the number 1/2 is rational, but it is not an integer.
=====================================
Rational numbers do not include integers.
This is false. As stated earlier, any integer can be placed over 1 to form a rational number. So the rational numbers do include integers, among non-whole number fractions as well.

Answer:
[tex] -ax - 20 = -14 [/tex] => [tex] x = -\frac{6}{a} [/tex]
[tex] 4 = \frac{6}{a}x + 5 [/tex] => [tex] x = -\frac{a}{6} [/tex]
[tex] 7 + 2ax = 13 [/tex] => [tex] x = \frac{3}{a} [/tex]
Step-by-step explanation:
[tex] -ax - 20 = -14 [/tex]
[tex] -ax - 20 + 20 = -14 + 20 [/tex]
[tex] -ax = 6 [/tex]
[tex] \frac{-ax}{-a} = \frac{6}{-a} [/tex]
[tex] x = -\frac{6}{a} [/tex]
[tex] 4 = \frac{6}{a}x + 5 [/tex]
[tex] 4 - 5 = \frac{6}{a}x + 5 - 5 [/tex]
[tex] - 1 = \frac{6}{a}x [/tex]
[tex] - 1*\frac{a}{6} = \frac{6}{a}x*\frac{a}{6} [/tex]
[tex] -\frac{a}{6} = x [/tex]
[tex] x = -\frac{a}{6} [/tex]
[tex] 7 + 2ax = 13 [/tex]
[tex] 7 + 2ax - 7 = 13 - 7 [/tex]
[tex] 2ax = 6 [/tex]
[tex] \frac{2ax}{2a} = \frac{6}{2a} [/tex]
[tex] x = \frac{3}{a} [/tex]

What is the equation of the transformation of y=x^2, up 4 units and right 2 units?
Answer:
y = (x -2)^2 +4
Step-by-step explanation:
Translation (right, up) by (h, k) gives you the function ...
g(x) = f(x -h) +k
You want f(x) = x^2 to be translated right 2 and up 4, so it becomes ...

Answer:
B. x = 7/2 or x=-1/3
Step-by-step explanation:
You know both angles 6x² and 19x+7 have to be the same, so you can solve
6x² = 19x+7
6x² - 19x - 7 = 0
apply the quadratic formula and find
x = -1/3 or x = 7/2
now think carefully if the negative x is a realistic solution. It would lead to the angles being (2/3)°. This is not what the picture suggests, but it is also not wrong, so answer B seems the best.

DUE SOON PLEASE HELP Find the value of x. A. 40 B. 95 C. 45 D. 22.5
Answer:
D. 22.5
Step-by-step explanation:
By the property of intersecting tangent and secant outside of the circle, we have:
x° = 1/2[(4x+5)° - 50°]
2x° = [(4x+5)° - 50°]
2x° = (4x-45)°
2x = 4x - 45
45 = 4x - 2x
45 = 2x
x = 45/2
x = 22.5
The measure of the variable x will be 22.5°. Then the correct option is D.
What is a circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
We know that half of the difference between the angle (4x + 5)° and 50° will be equal to x°. Then the equation will be
x = [4x + 5 - 50] / 2
Simplify the equation, then we have
2x = 4x - 45
2x = 45
x = 22.5°
The measure of the variable x will be 22.5°.
Then the correct option is D.

Which equation is true?
15 - 112.5 = 7.5
15 : 112.5 = 75
112.5 : 15 = 7.5
112.5 : 15 = 75
What’s the answer
Answer:
112.5:15=7.5
Step-by-step explanation:
112.5:15
=112.5÷15
=7.5
The equation "112.5 : 15 = 7.5" is true.
Proceed option 1:
"15 - 112.5 = 7.5":
This equation is not correct because 15 - 112.5 does not equal 7.5.
Proceed option 2:
"15 : 112.5 = 75":
This equation is not correct because when we divide 15 by 112.5, we get a decimal answer of 0.1333, not 75.
Proceed option 3:
"112.5 : 15 = 7.5": This equation is correct.
When we divide 112.5 by 15, we get an answer of 7.5.
Proceed option 4:
"112.5 : 15 = 75": This equation is not correct because when we divide 112.5 by 15, we get an answer of 7.5, not 75.
Hence equation "112.5 : 15 = 7.5" is correct.

Li uses 8.4 grams of sugar every day in her tea. Sue uses 12.6 grams of sugar every day in her coffee. If Li’s sugar canister contains 128 grams of sugar and Sue’s canister contains 191 grams, in how many days will Li and Sue have the same amount of sugar in their canisters?
Answer:
They will have the same amount of sugar in their canisters in 15 days
Step-by-step explanation:
Here in this question, we are concerned with knowing the number of days in which the amount of sugar in both canisters will be the same.
Since we do not know the number of days it will
take, we have to represent it using a variable.
Let the number of days be x days
Now, we are told Li uses 8.4 g per day.
So in x days, the amount user will be 8.4 * x = 8.4x g
Thus, the amount of sugar remaining in her canister after x days will be 128 - 8.4x
For Sue, she uses 12.6 grams each day. So in x days, the amount of sugar used will be 12.6 * x = 12.6x g
So the amount of sugar left in her canister will be 191-12.6x
Since on the xth day , the amount of sugar remaining is same, we can equate the amount of sugar remaining in both canisters. That would be;
128-8.4x =191-12.6x
Collect like terms;
12.6x-8.4x = 191-128
4.2x = 63
x = 63/4.2
x = 15 days
