Answer:
A. Two squares with the same side lengths are always congruent.
Step-by-step explanation:
Congruence is a relation that shows similarity between the shape or size of two or more given figures. It can be determined by comparing the size of the angles or sides of the figures involved.
A square has equal length of sides, therefore two squares with the same side lengths are always congruent in all respect (shape and area). The statement in option a is TRUE.

The green shaded region does not represent the
solution to the system of linear inequalities given
below. Explain why not.
y²2
35x+2y= 20
Answer:
Step-by-step explanation:
Region represented by the inequality y ≥ 2 will be the area above the dark line y = 2.
Equation of the other line is,
3.5x + 2y ≤ 20
2y ≤ 20 - 3.5x
y ≤ -1.75x + 20
Shaded region representing the solution of the inequality will be below the solid line y ≤ -1.75x + 20.
Therefore, solution of the system of inequalities will be the common region of both the colors in the graph attached.
Graph of the question will not represent the solution of the system of inequalities.
Answer:
The blue line should be solid because the inequality has “or equal to.” The green shading should be on the other side of the blue line. The blue line should be part of the solution set.

Find the slope of the line that passes through (8,4) and (5, 3).
Answer:
The answer is
[tex] \frac{1}{3} \\ [/tex]
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1}\\[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(8,4) and (5, 3).
The slope is
[tex]m = \frac{3 - 4}{5 - 8} = \frac{ - 1}{ - 3} = \frac{1}{3} \\ [/tex]
We have the final answer as
[tex] \frac{1}{3} \\ [/tex]
Hope this helps you
Step-by-step explanation:
Hey there!
Here;
The given coordinates are(8,4) and (5,3).
Use slope formulae.
[tex]slope(m) = \frac{y2 - y1}{x2 - x1} [/tex]
Put all values.
[tex]m = \frac{3 - 4}{5 - 8} [/tex]
Simplify it to get answer.
[tex]m = \frac{ - 1}{-3} [/tex]
Therefore the slope is, 1/3.

The midpoint of AB is M(-6, -6). If the coordinates of A are (-4-8), what are
the coordinates of B?
Answer:
The coordinates of B are (-8,-4)
Step-by-step explanation:
Midpoint of a segment
Given points A(xa,ya) and B(xb,yb), the coordinates of the midpoint M can be found knowing that:
[tex]\overline{AM}=\overline{MB}[/tex]
Applying that relation in both axes separately, we can write:
[tex]x_A-x_M=x_M-x_B[/tex]
[tex]y_A-y_M=y_M-y_B[/tex]
Knowing the coordinates of the midpoint and A, we can find the coordinates of the other extreme B solving both equations for the required variable:
[tex]x_B=2x_M-x_A[/tex]
[tex]y_B=2y_M-y_A[/tex]
Plugging in the known values:
[tex]x_B=2(-6)-(-4)=-12+4=-8[/tex]
[tex]y_B=2(-6)-(-8)=-12+8=-4[/tex]
The coordinates of B are (-8,-4)

A city known for its temperature extremes started the day at -5 degrees Fahrenheit. The temperature increased by 78 degrees Fahrenheit by midday, and then dropped 32 degrees by nightfall. What expression can you write to find the temperature at nightfall?
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Starting temperature = - 5°F
Temperature at midday =increase in temperature by 78°F = (starting temperature + 78°F)
Temperature at nightfall = decrease in temperature by 32°F = ( temperature at midday - 32°F)
Temperature at midday:
(-5°F + 78°F) = 73°F
Temperature at nightfall:
(Temperature at midday - 32°F)
(73°F - 32°F) = 41°F

6x + 10 = 4x - 4
solve your equation by subtracting 10 on both sides to make -4 -14
6x = 4x - 14
subtract 4x on both sides to get 2x
2x = -14
divide -14 by 2x
x = -7
Check it by plugging it in the equation
-42 + 10 = -28 - 4
-32 = -32

Which of the following is a solution of the equation 9 - 2x = -1?
(A) -5
(B) 5
(C) 4
(D) -4
Answer: B) X = 5
Step-by-step explanation:
You need to get x by itself to find the solution, that means adding/subtracting anything around it first which is 9.
your new equation would be -2x = -10
to get x completely alone, divide it by -2 and divide the other side, it makes x = 1 which is how to solve for it, when you divide -10 by it you get the answer of x = (B) 5

Kelly runs a distance of 100 metres in a time of 10.52 seconds.
The distance of 100 metres was measured to the nearest metre.
The time of 10.52 seconds was measured to the nearest hundredth of a second.
Write down the upper bound for the distance of 100 metres.
Answer:
Upper bound for distance = 100.49. This is the highest number that you can round up to get 10.52.
Lower bound for time = 10.515 seconds. This is the lowest number that you can round up to get 10.52.
Upper bound for average speed = Upper bound for distance divided by upper bound for time.
100.49/10.5249 = 9.548 seconds.
Lower bound for average speed = Lower bound for distance divided by lower bound for time.
99.5 / 10.515 = 9.463 seconds.
Step-by-step explanation:
Hope this helps you out.
The upper bound for the distance of 100 metres is 100.4 meters.
What is meant by rounding off?Rounding off means a number is made simpler by keeping its value intact but closer to the next number.
Given:
Kelly runs a distance of 100 metres in a time of 10.52 seconds.
The upper bound represents the highest number, to which round off can be done to the nearest unit.
We have distance of 100 metres
So, the upper bound for the distance is 100.4 meters.
Hence, the upper bound for the distance is 100.4 meters.

1) If 2x + 3y = 12 and xy = 6, find the value of 4x2 +9y2.
Answer:
72
Step-by-step explanation:
Given that 2x + 3y = 12 , then
(2x + 3y)² = 12² = 144 ← distribute left side using FOIL
4x² + 12xy + 9y² = 144 ( subtract 12xy from both sides )
4x² + 9y² = 144 - 12xy = 144 - 12(6) = 144 - 72 = 72

Convert the following angle from degrees to radians. Express your answer in simplest form. 690∘
23π / 6 radians is equivalent to the 690-degrees.
To convert degrees to radians, we use the formula:
radians = degrees × π / 180
Therefore, for 690 degrees:
radians = 690 × π / 180
Simplifying this expression:
radians = 23π / 6
Therefore, 690 degrees is equivalent to 23π / 6 radians.

What will be the coordinates of point N after a 270° counterclockwise rotation about the origin?
Answer:
N(-4, 1)
Step-by-step explanation:
Counterclockwise means anti clockwise.
Now, when rotated by 90° about the origin, the point N will be in the second quadrant starting clockwise from the 0 - 90° quadrant
When it's rotated counterclockwise by another 90°, it will be at the first quadrant starting clockwise from the 0 - 90° quadrant
When it's rotated another 90°, it will be located in the 4th quadrant starting clockwise from the 0 - 90° quadrant.
Thus, after 270° N will be in the 4th quadrant starting clockwise from the 0 - 90° quadrant.
Therefore, the coordinates of N at that point will be;
On x - axis: -4 units
On y - axis: 1 unit
Thus coordinates are;
N(-4, 1)
