What is the equation of the line in slope-intercept form that is perpendicular to the line y=3/4x-2 and passes through the point (–12, 10)?
y =-4/3 x – 6
y = -4/3 x + 6
y = 4/3 x + 26
y = 4/3 x + 10
Answer:
A
Step-by-step explanation:
You have to plug numbers into point slope formula (make sure to use a slope of -4/3 since its perpendicular) and then solve for y.

(a) Describe the relationship among the lengths of the segments formed by two secants. You may use words and/or and equation.
(b) Suppose CG = 3 in, CH = 2 in, and GE = 5 in, is it possible to find the length of DH? If so, show how to find the length. If not, explain why not.
Help would be appreciated!
Based on the intersecting secants theorem:
a. CG*CE = CH*CD
b. length of DH = 10 in.
What is the Intersecting Secants Theorem?When an exterior point is formed by two secant segments to a circle, the product of the length of one secant segment and its external segment will always be equal to the product of the length of the other secant segment and its external segment, according to the intersecting secants theorem.
a. Based on the intersecting secants theorem, the relationship that describes the lengths of the segments formed by the two secants is:
CG*CE = CH*CD
b. Given the following lengths:
CG = 3 in, CH = 2 in, and GE = 5 in
CE = CG + GE = 3 + 5 = 8 in.
CD = CH + DH = 2 + DH
Substitute into CG*CE = CH*CD:
3*8 = 2*(2 + DH)
24 = 4 + 2DH
24 - 4 = 2DH
20 = 2DH
20/2 = DH
DH = 10 in.

Given: AD=AC (Triangle ADC is isosceles) and B is the midpoint of segment DC Complete the blanks proving that segment AB is the perpendicular bisector of segment DC.
It is given that AD = AC is the midpoint of the segment DC. Therefore, DB = BC by the definition of the midpoint making the segment AB as a bisector. Additionally, ∠D is congruent to the angle ∠C by the definition of the vertical angle theorem. Triangle ΔADB is congruent to triangle ΔACB by SAS theorem.
Since angles like ∠ ABD and ∠ABC are a linear pair adding up to 180 and congruent by linear pair postulate. This means that the angle ABD and ABC each measures 90 degrees. Therefore, segment AB is perpendicular to segment DC by midpoint isosceles theorem making segment AB both as a bisector and perpendicular to the segment DC.

a) The length of the perpendicular drawn from the point (a, 3) on the line
3x + 4y + 5 = 0 is 4. Find the value of a.
Answer:
We know that for a line:
y = a*x + b
where a is the slope and b is the y-intercept.
Any line with a slope equal to -(1/a) will be perpendicular to the one above.
So here we start with the line:
3x + 4y + 5 = 0
let's rewrite this as:
4y = -3x - 5
y = -(3/4)*x - (5/4)
So a line perpendicular to this one, has a slope equal to:
- (-4/3) = (4/3)
So the perpendicular line will be something like:
y = (4/3)*x + c
We know that this line passes through the point (a, 3)
this means that, when x = a, y must be equal to 3.
Replacing these in the above line equation, we get:
3 = (4/3)*a + c
c = 3 - (4/3)*a
Then the equation for our line is:
y = (4/3)*x + 3 - (4/3)*a
We can rewrite this as:
y = (4/3)*(x -a) + 3
now we need to find the point where this line ( y = -(3/4)*x - (5/4)) and the original line intersect.
We can find this by solving:
(4/3)*(x -a) + 3 = y = -(3/4)*x - (5/4)
(4/3)*(x -a) + 3 = -(3/4)*x - (5/4)
(4/3)*x - (3/4)*x = -(4/3)*a - 3 - (5/4)
(16/12)*x - (9/12)*x = -(4/3)*a - 12/4 - 5/4
(7/12)*x = -(4/13)*a - 17/4
x = (-(4/13)*a - 17/4)*(12/7) = - (48/91)*a - 51/7
And the y-value is given by inputin this in any of the two lines, for example with the first one we get:
y = -(3/4)*(- (48/91)*a - 51/7) - (5/4)
= (36/91)*a + (153/28) - 5/4
Then the intersection point is:
( - (48/91)*a - 51/7, (36/91)*a + (153/28) - 5/4)
And we want that the distance between this point, and our original point (3, a) to be equal to 4.
Remember that the distance between two points (a, b) and (c, d) is:
distance = √( (a - c)^2 + (b - d)^2)
So here, the distance between (a, 3) and ( - (48/91)*a - 51/7, (36/91)*a + (153/28) - 5/4) is 4
4 = √( (a + (48/91)*a + 51/7)^2 + (3 - (36/91)*a + (153/28) - 5/4 )^2)
If we square both sides, we get:
4^2 = 16 = (a + (48/91)*a + 51/7)^2 + (3 - (36/91)*a - (153/28) + 5/4 )^2)
Now we need to solve this for a.
16 = (a*(1 + 48/91) + 51/7)^2 + ( -(36/91)*a + 3 - 5/4 + (153/28) )^2
16 = ( a*(139/91) + 51/7)^2 + ( -(36/91)*a - (43/28) )^2
16 = a^2*(139/91)^2 + 2*a*(139/91)*51/7 + (51/7)^2 + a^2*(36/91)^2 + 2*(36/91)*a*(43/28) + (43/28)^2
16 = a^2*( (139/91)^2 + (36/91)^2) + a*( 2*(139/91)*51/7 + 2*(36/91)*(43/28)) + (51/7)^2 + (43/28)^2
At this point we can see that this is really messy, so let's start solving these fractions.
16 = (2.49)*a^2 + a*(23.47) + 55.44
0 = (2.49)*a^2 + a*(23.47) + 55.44 - 16
0 = (2.49)*a^2 + a*(23.47) + 39.44
Now we can use the Bhaskara's formula for quadratic equations, the two solutions will be:
\(a = \frac{-23.47 \pm \sqrt{23.47^2 - 4*2.49*39.4} }{2*2.49} \\\\a = \frac{-23.47 \pm 12.57 }{4.98}\)
Then the two possible values of a are:
a = (-23.47 + 12.57)/4.98 = -2.19
a = (-23.47 - 12.57)/4.98 = -7.23

Eric is planning to fly to New Jersey. If he flies non-stop to New Jersey from San Diego, he will fly
2,786 miles. If he flies from San Francisco, he will fly 698 miles to Denver, 678 miles to Chicago and
965 miles to New Jersey.
Which route will be the longest for Eric to fly? By how many miles?
A.the flight from San Francisco by 440 miles
B.the non-stop flight from San Diego by 400 miles
C.the non-stop flight from San Diego by 445 miles
D.the flight from San Francisco by 445 miles
Answer: To find the longest route for Eric to fly, we need to add up the distances for each option and compare them.
Option A: San Francisco to Denver to Chicago to New Jersey
Total distance = 698 + 678 + 965 = 2,341 miles
Option B: Non-stop from San Diego to New Jersey
Total distance = 2,786 miles
Option C: Non-stop from San Diego to New Jersey
Total distance = 2,786 miles
Option D: San Francisco to Denver to Chicago to New Jersey
Total distance = 698 + 678 + 965 = 2,341 miles
Therefore, the longest route for Eric to fly is Option D, from San Francisco to Denver to Chicago to New Jersey, which is 2,341 miles. This is longer than the non-stop flight from San Diego (Option B) by 445 miles. Therefore, the answer is (D) the flight from San Francisco by 445 miles.

Answer:
(a) C = 0.29t + 2.50
(b) 5
Step-by-step explanation:
The variables are defined as follows:
t = the number of toppings
C = total cost for ice cream
It is provided that:
An ice cream with no toppings is $2.50.Every topping is priced at $0.29 each.(a)
The algebraic equation to find the total cost for ice cream depending on the number of toppings is:
C = 0.29t + 2.50
(b)
Compute the number of toppings Mr. Torrance can buy if he wants to spend only $4.00 on it as follows:
C = 0.29t + 2.50
4.00 = 0.29t + 2.50
0.29t = 4.00 - 2.50
0.29t = 1.50
t = 5.1724
t ≈ 5
Thus, Mr. Torrance can buy 5 toppings.

The value of x in the polygon will be 13.25 degrees.
The value of x is 10.
We can find the value of x by plugging in the number of sides of the regular polygon into the formula x = (n-2)*15° - 1.
How to calculate the valueThe sum of the interior angles of a regular polygon with n sides is (n-2) x 180 degrees.
Sum of angles = (24-2) x 180 = 22 x 180 = 3960 degrees
Since all the angles in a regular polygon are congruent, we can divide the sum of the angles by the number of angles to find the measure of one angle:
Measure of one angle = 3960/24 = 165 degrees
165 = 12x + 6
159 = 12x
x = 13.25
Therefore, the value of x is 13.25 degrees.
Each of the triangles in our decomposition has one angle equal to (17x+2)°, so the sum of all the angles in the triangles is 43 × (17x+2)° = 731x+86°.
Therefore, we have:
731x+86° = 7380°
Solving for x, we get:
731x = 7294°
x = 10
Therefore, the value of x is 10.
The equation that can be used to find the value of x is:
(9x+48)° + (15x-24)° = (n-2)*180°
24x + 24 = (n-2)*180°
Dividing both sides by 24, we get:
x + 1 = (n-2)*15°
Subtracting 1 from both sides, we get:
x = (n-2)*15° - 1
