The next step of the valid proof is that AE = CE because of the perpendicular bisector theorem.
What is a perpendicular bisector theorem?The perpendicular bisector theorem states that any point on the perpendicular bisector is equidistant from the endpoints of the line segment on which it is drawn.
In this case, Julia is using this figure to prove that triangle ABC is an isosceles triangle. After the steps given, the next step will be to indicate that AE = CE because of the perpendicular bisector theorem.

Answer:
x is -1
Step-by-step explanation:
-4 multiplied by x is -4x, then -4 x 3 is -12, which makes the problem -4x + -12 and you need to do the opposite so add 4, -4x cancels out and then add 4 to -12 which is 8x

A circle is centered at the point (-3, 2) and passes through the point (1, 5). The radius of the circle is ____? units. The point (-7, __?) lies on this circle.
Answer:
the answer is 5 and (-7,5)
Step-by-step explanation:
The radius is 5, and the points (-7, 5) and (-7, -1) both lie on the circle.
Given that:
The points at which the circle is centered are (-3,2)
Passing points = (1,5)
The radius is calculated using the distance formula:
d = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2[/tex]
Substituting the coordinates, we have:
d =[tex]\sqrt{({1 - (-3))^2 + (5 - 2)^2[/tex]
= [tex]\sqrt{(1 + 3)^2 + (5 - 2)^2[/tex]
=[tex]\sqrt{(4^2 + 3^2)[/tex]
= [tex]\sqrt{(16 + 9)[/tex]
= 5
Therefore, the radius of the circle is 5 units.
The equation of a circle with center (h, k) and radius r is given by:
[tex](x - h)^2 + (y - k)^2 = r^2[/tex]
Substituting the values, we have:
[tex][-7 - (-3)]^2 + (y - 2)^2 = 5^2[/tex]
[tex](-7 + 3)^2 + (y - 2)^2 = 25[/tex]
[tex](-4)^2 + (y - 2)^2 = 25[/tex]
[tex]16 + (y - 2)^2 = 25[/tex]
[tex](y - 2)^2 = 9[/tex]
Taking the square root of both sides, we have:
y - 2 = ±3
Solving for y, we have two possible values:
y - 2 = 3
y = 5
y - 2 = -3
y = -1
The points (-7, 5) and (-7, -1) both lie on the circle.
Thus, the radius is 5, and the points (-7, 5) and (-7, -1) both lie on the circle.

A training field is formed by joining a rectangle and two semicircles, as shown below. The rectangle is 86m long and 64m wide. Find the area of the training field. Use the value 3.14 for π, and do not round your answer. Be sure to include the correct unit in your answer.
The area of the training field to the nearest whole number is 8719 msq. meter
Area of composite solidThe given field is made up of a rectangle and 2 semi circles. The formula for calculating the area of the field is:
Area of the field = area of circle + area of rectangle
Area of field = 3.14(32)² + (86)(64)
Area of field = 3215.36 + 5504
Area of the field = 8719 msq. meter
Hence the area of the training field to the nearest whole number is 8719 msq. meter

2. Martin read for a total of 150 minutes last week. He read the same amount of time each day for 6 days. Which equation shows, n, the number of minutes Martin read each day? 150 minutes in all n minutes read each day A 150 x 6-n B 150+6=n 150-6-n D 150+6=n
Answer:
n = 150/6
or
n = 25
Step-by-step explanation:
Since martin read during 150 minutes for six days, all you need to do is divide the time by the amount of days to get how many minutes (n) martin read per day.
Therefore, n = 150 / 6
If you make the division n = 25

What are the x-intercepts of the graph of the given function f(x)=3(x+7)(x-9) show your work
Answer:
x intercepts = (9,0), (-7,0)
Step-by-step explanation:
First lets expand the factored equation.
f(x) = 3(x + 7) (x - 9)
.... = 3x + 21 (x - 9)
....= 3x^2 - 27x - 21x - 189
....= 3x^2 - 6x - 189
lets make the quation equal to 0 and use the Factorization method to solve for x.
3x^2 - 6x - 189= 0
3(x^2 - 2x - 63) = 0
3(x - 9) (x + 7) = 0
x - 9 = 9 and x + 7 = -7
x = 9,
x = -7
Let U=(1,2,3,4,5,6,7,8,9,10) Let A = {2,4,6,8,10}. Let B=(1,3,4,6,9} Determine (A - B)'.
A - B is the complement of B in A; in other words, all the elements of A that do not belong to B.
Since A ∩ B = {4, 6}, we have
A - B = {2, 8, 10}
Then the complement of A - B, denoted (A - B)' is all the elements of the universal set U that do not belong to A - B.
(A - B)' = {1, 3, 4, 5, 6, 7, 9}

What is a regular polygon?A regular polygon is a polygon that has two dimensions and can be made or drawn using at least three lines joined together.

Answer:
t = 110°
Step-by-step explanation:
Triangle BCD is isosceles, so its base angles are congruent. This means m<CBD = m<CDB. Since m<CBD is 35, m<CDB is also 35.
The sum of angles in a triangle is 180, so the following equation can be written:
180 = m<CBD + m<CDB + m<BCD
We can substitute m<CBD and m<CDB with 35 and m<BCD with t and solve:
[tex]180 = 35 + 35+ t\\180=70+t\\t=110[/tex]
So t = 110°
