Answer:
(9.5, 6.5) and (-4.5, -7.5)Step-by-step explanation:
Let the extended points be A' and B' and add the point M as midpoint of AB
Coordinates of M are:
((6 - 1)/2, (3-4)/2) = (2.5, -0.5)Now point A is midpoint of A'M and point B is midpoint of MB'
Finding the coordinates using midpoint formula:
A' = ((2*6 - 2.5),(2*3 - (-0.5)) = (9.5, 6.5)B' = ((2*(-1) - 2.5), (2*(-4) - (-0.5)) = (-4.5, -7.5)SOMEONE, PLEASE HELP LITERALLY STRUGGLING!!!!!!

6) Choose which postulate proves the triangles congruent.
Answers
Answer:
SAS(Side.Angle.Side
Step-by-step explanation:
since x is mid point of pr and qs so px=xr and x is midpoint of qs so qx=sx,
and two lines intercept so angles made on point x are equal.....hence 2 sides and one angle proved so triangles are equal
The postulate that can be used to prove that triangle QXP and triangle SXR are congruent to each other is: SAS Congruence Theorem,
Recall:
Two triangles are congruent by the Side-Angle-Side Congruence Theorem, if two sides and one included angle of one triangle are congruent to two sides and the corresponding included angle in the other triangle.Since X is a midpoint of QS and RP, therefore:
[tex]PX \cong RX\\\\QX \cong SX\\[/tex]
Also,<PXQ = <SXR (vertical angles are congruent)
Thus, triangle QXP and triangle SXR are congruent by SAS.Therefore, the postulate that can be used to prove that triangle QXP and triangle SXR are congruent to each other is: SAS Congruence Theorem,

Answers
Answer:
Joey completed 52 pushups each day.
Step-by-step explanation:
We know that he did 1,456 pushups in 4 weeks, and that there are 7 days a week. This means that he did those pushups in the span of 28 days. So, divide 1,456 by 28 to get 52 pushups.

Answer:
18.6cm (rounded to 3 s.f.)
Step-by-step explanation:
You can actually figure out the two bases of the triangles based on the Pythagoras theorem where the slant length of a 90° triangle is [tex]\sqrt{a^{2} + b^{2} }[/tex] where a is one of the bases and b is the other length that is 90° perpendicular to a.
So this means:
[tex]\sqrt{6^{2} + base^{2} }[/tex] = 8cm
6² + base² = 64cm
36 + base² = 64
base² = 64-36
= 28
base = [tex]\sqrt{28}[/tex]
≈ 5.2915 (5 s.f.)
So the two bases are roughly 5.2915, and the middle base is part of a rectangle, so it has the same length as the rectangle's length, which is 8cm.
Thus, x = 5.2915 + 5.2915 + 8
= 18.6cm (rounded to 3 s.f.)

There was a study done on oxygen consumption of snails as a function of pH, and the result was a degree 4 polynomial whose graph is shown.
Which of the following statements about this function is INCORRECT?
Answers
Answer:
A. There is a positive leading coefficient
Step-by-step explanation:
Polynomials can be represented as an equation or graphs.
The incorrect option is: (b) There is a positive leading coefficient.
The polynomial has a degree of 4; this means that the degree of the polynomial is even.
So option (a) The degree of the polynomial is even is true
From the graph, we can see that the function decreases at (7<x<8) and (9<x<10)
This means that, the function decreases at two intervals
So option (d) There are two intervals where the function is decreasing is also true
Also, the function is at maximum at x = 7 and x = 9.
This means that:
Option (c) At two pH values, there is a relative maximum value
Hence, the incorrect option is:
(b) There is a positive leading coefficient.
This is so because, the graph decreases at some points on the graph.
This means that, the graph has a negative leading coefficient.

The walls of a square room need painting. Each of the four walls is 12ft wide by 8.5 feet tall. One gallon of paint covers 75ft2. How many gallons will you need
Answers
Answer:
5.44 gallons of paint
Step-by-step explanation:
First, we calculate the total area of the walls we need to paint. To do this, we use the formula for the area of a rectangle and we multiply our answer by 4, since there are 4 walls.
Area=(length*width)4
Area=(12*8.5)4
Area=(102ft^2)4
Area=408ft^2
Therefore, the total area of the walls is 408ft^2.
Now, we need to calculate the number of gallons we need to paint 408ft^2 worth of wall. Because we know that one gallon of paint covers 75ft^2, we can calculate this by dividing 408 by 75.
408/75
=5.44 gallons
Therefore, we would need 5.44 gallons of paint to paint the four walls.
