Your cousin says he can find 964 + 4,691 by starting at $4,691 on a number line because of the Associative Property of Addition. Explain why your cousin's reasoning is incorrect.
Your cousin's reasoning is incorrect because the Associative Property of Addition does not applying to the starting point on a number line.
How is your cousin wrong ?The Associative Property of Addition states that the order in which numbers are added does not affect the sum. So, for example, (3 + 4) + 5 = 3 + (4 + 5) = 12.
However, this property only applies to the order in which numbers are being added together, not the starting point on a number line. In order to find the sum of 964 + 4,691, one would need to start at 964, then add 4,691 to that sum. It is not correct to start at 4,691 on the number line and add 964 to that number because it does not take into account the original starting point.

Here's a graph of a linear function. Write the
equation that describes that function.
xpress it in slope-intercept form.
Answer:
the slope intercept form is y = (1/2)x - 1
Step-by-step explanation:
The slope-intercept form is, y = mx + b
We see from looking at the graph that,
at x = 0, y = -1
So, from this we find that b = -1
at x = 2, y = 0,
now, we find the slope m,
using,
\(m = \frac{y_{2} -y_1}{x_2-x_1}\)
Using x_2 = 2, y_2 = 0,
x_1 = 0, y_1 = -1, we get,
m = (0-(-1))/(2-0)
m = 1/2
So, the slope intercept form is,
y = (1/2)x - 1
find the 9th term of the geometric sequence. 12,36,108,...
The 9th term of the given sequence is 78732.
The given sequence is 12, 36, 108... is a geometric sequence with a common ratio of 3.To find the 9th term of the given sequence, we will use the formula for the nth term of a geometric sequence, which is given by:
aₙ = a₁rⁿ⁻¹
Here, a₁ = 12 and r = 3.
Therefore, the formula for the nth term becomes:
aₙ = 12(3)ⁿ⁻¹
Now, we need to find the 9th term of the sequence. Hence, n = 9. Substituting the values of a₁ and r, and n in the formula, we get:
a₉ = 12(3)⁹⁻¹= 12(3)⁸= 12(6561)= 78732

Solve the following equation:
8x + 3 = 2x + 9
Answer:
\(\Huge \boxed{\boxed{ x = 1}}\)
Step-by-step explanation:
Isolate the variable on one side of the equation before trying to solve it. It means that you should only have constants (numbers) on the other side of the equal sign and the variable alone on the one side.
To do this, you can add, subtract, multiply, divide, or use any other operation to both sides of the equation as long as you do the same thing on both sides.
Your final step depends on the equation and how you've simplified it. In general, you want to figure out how you arrived at the final equation by working backwards from it. You'll isolate the variable in the last action you took.
-------------------------------------------------------------------------------------------------------------
SolutionStep1: Subtract \(\bold{2x}\) from both sides
\(8x + 3 = 2x + 9\)\(8x - 2x + 3 = 2x - 2x + 9\)\(6x + 3 = 9\)Step 2: Subtract 3 from both sides
\(6x + 3 - 3 = 9 - 3\)\(6x = 6\)Step 3: Divide both sides of the equation by 6
\(\frac{6x}{6} = \frac{6}{6}\)\(x = 1\)So the solution to the equation \(\bold{8x + 3 = 2x + 9}\) is \(\bold{x = 1}\).

bala had 240 cards and tom had 780 cards. after tom gave some cards to bala, bala had twice as many cards as tom. how many cards did tom give to bala?
The answer is tom will give 440 cards to Bala, using arithmetic operation.
What is the arithmetic operation?
The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or more quantities. Included in them is the study of numbers, especially the order of operations, which is important for all other areas of mathematics, including algebra, data management, and geometry. The rules of arithmetic operations are required in order to answer the problem.
The total number of cards is 780+240 = 1020.
If in the end Bala will have twice as many cards as Tom then I would divide the 1020 by 3 which equals 340.
So Bala will have 2*340 = 680 cards
Tom will have 340 cards.
Now Bala will need (680-240) = 440 more cards.
Hence Tom will give 440 cards to Bala.

Height is a proportional to foot length. A person whose foot length is 10 inches is 67 inches tall. A human-like creature has a foot length of 27 inches. Use a proportion to find the height of the creature.
Answer:
180.9 inches.
Step-by-step explanation:
Given that height is a proportional to foot length, and a person whose foot length is 10 inches is 67 inches tall, if a human-like creature has a foot length of 27 inches, to determine the height of the creature the following mathematical calculation:
10 = 67
27 = X
27 x 67/10 = X
27 x 6.7 = X
180.9 = X
Thus, the height of the creature is 180.9 inches.

For a project in her Geometry class, Deepa uses a mirror on the ground to measure the height of her school’s football goalpost. She walks a distance of 9.35 meters from the goalpost, then places a mirror on flat on the ground, marked with an X at the center. She then steps 6.95 meters to the other side of the mirror, until she can see the top of the goalpost clearly marked in the X. Her partner measures the distance from her eyes to the ground to be 1.35 meters. How tall is the goalpost? Round your answer to the nearest hundredth of a meter.
Deepa makes use of the geometric property of similar triangles formed by
incident and reflected rays to determine the height of the goalpost.
The height of the goalpost is approximately 1.82 metersReasons:
When an object is reflected on a mirror, the angle of incidence, θ₁ is equal
to the angle of reflection, θ₂.
θ₁ = θ₂
Given that the angle, ∅₁, the incident ray of light and the angle, ∅₂, the
reflected light make with horizontal are both complementary angles, to the
angle of incident and reflection, respectively, we have;
θ₁ + ∅₁ = θ₂ + ∅₂
θ₁ = θ₂
Therefore, by subtraction property of equality, we have;
∅₁ = ∅₂
The vertical line from the top of the goalpost to the base of the goalpost
and the the vertical line from Deepa's eyes to the ground on which her feet
is standing are both perpendicular to the ground, therefore, the light from
the top of the goalpost to the mirror and to her eyes form similar triangles
by Angle Angle similarity postulate, which gives;
\(\displaystyle \frac{6.95}{9.35} = \frac{1.35}{The \ height \ of \ the \ goalpost}\)
6.95 × Height of the goalpost = 1.35 × 9.35
\(\displaystyle Height \ of \ the \ goalpost = \frac{1.35 \ m \times 9.35 \ m}{6.95 \ m} \approx 1.82 \ m\)
The height of the goalpost is approximately 1.82 meters.

If GI and JL are parellel lines and m
The measure of angle IHE is 23°.
Since DF and GI are parallel, we know that angle HJF is congruent to angle GHJ. Therefore, we have:
mHJF = mGHJ = 134°
We can now use this information to find the measure of angle IHE. To do this, we need to use the fact that the sum of the angles in a straight line is 180°. Since H, J, F, and I lie on a straight line, we have:
mHJF + mFJI + mIHE = 180°
Substituting the values we know, we get:
134° + mFJI + mIHE = 180°
Simplifying the equation, we get:
mFJI + mIHE = 46°
We still need to find the measure of angle FJI. To do this, we can use the fact that the angles in a triangle add up to 180°. Triangle GHJ is a straight line, so its angles add up to 180°. Therefore, we have:
mGHJ + mHJF + mFJI = 180°
Substituting the values we know, we get:
134° + mFJI + mFJI = 180°
Simplifying the equation, we get:
2mFJI = 46°
Dividing both sides by 2, we get:
mFJI = 23°
Finally, we can substitute this value back into our earlier equation to find the measure of angle IHE:
mFJI + mIHE = 46°
23° + mIHE = 46°
Subtracting 23° from both sides, we get:
mIHE = 23°
