Find the GCF of the two numbers using the distributive property then rewite the sum
20 + 16
To find the GCF of 20 and 16 using the distributive property, we need to break down the numbers into their prime factors.
20 = 2 x 2 x 5
16 = 2 x 2 x 2 x 2
The greatest common factor is 2 x 2 = 4.
To rewrite the sum of 20 + 16 using the GCF, we can factor out 4 from both numbers:
20 + 16 = 4 x 5 + 4 x 4
Using the distributive property, we can simplify this expression:
20 + 16 = 4(5 + 4)
Therefore, the GCF of 20 and 16 is 4, and the sum can be rewritten as 4(5 + 4).
The distributive property allows us to factor out a common factor from an expression. In this case, we found the GCF of the two numbers using prime factorization and then used the distributive property to simplify the sum. By factoring out the GCF, we were able to rewrite the sum in a more simplified form.
The GCF of 20 and 16 is 4, and the sum can be rewritten as 4(5 + 4) using the distributive property. Factoring out the GCF can help simplify expressions and make them easier to work with.

1. What is the solution of the matrix equation?[: L1-62(-2, 1)(10, 6)(-4, 3)(-3, 4)
Answer:
(-3 , 4)
Step by step explanation:
1) 6x + 5y = 2
2) 5x + 4y = 1
we solve the first equation.
5y = 2 - 6x
y = (2 - 6x)/5
Then we replace Y in the second equation.
5x + 4*((2-6x)/ 5) = 1
5x + 8/5 - 24x/ 5 = 1
(8-24x)/5 + (5x*5)/5 = 1 * 5
(8-24x + 5x * 5)/ 5 = 5
8 - 24x + 25x = 5
8 + x = 5
X = -3
Then we replace x in the first equation.
(6*-3) + 5y = 2
-18 + 5y = 2
5y = 2 + 18
Y = 20/ 5
Y = 4

Please answer fast and show how u got the answer step by step thank u
The simple interest was $10.5 and the amount after 1 year would be $360.5 in her account.
What is the simple interest?Simple interest is defined as interest paid on the original principal and calculated with the following formula:
S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years. The rate of interest is in percentage r% and is to be written as r/100
We have been given data as
Principal amount (P) = $350
Time (T) = 1 year
The rate of interest (R) = 3%
Simple interest= P × R × T
Simple interest = 350 × 3/100 × 1
Simple interest = $10.5
So the amount after 1 year would be P + S.I. = 350 + 10.5 = $360.5
Therefore, the simple interest would be $10.5 and the amount after 1 year would be $360.5.

Write an equation in slope-intercept form for the line that passes through (9, 12) and is perpendicular to y=4
Answer:
\(x=9\)
Step-by-step explanation:
First, let's determine the slope! We know that the line is perpendicular to \(y=4\). This line is just a horizontal line that crosses the y-axis with a slope of 0. The line perpendicular to this will have the form \(x=?\). This is a straight, vertical line with indeterminate slope.
The line passes through the point (9, 12). If the line is going straight up and down, it will intercept every y-value, but only one x-value. The x-value in this ordered pair is 9. Therefore, the equation of the line is \(x=9\).
Which of the following could be the equation of the function below?

y = 3 sin (2 (x + pi)) + 2
The equation of the sine function will be y = -3 sin [2(x + π)] + 2. Then the correct option is A.
What is a sinusoidal Function?It is a function that repeats itself in a particular time interval.

What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
A flat screen television is a rectangle with a 53-invh diagonal and a width of 45 inches.
Here,
The diagonal of the screen television = 53 inches
And, The width of the screen television = 45 inches
Let the height of the television = h
So, By the Pythagoras theorem, we get;
⇒ AC² = AD² + DC²
Where, AC = Diagonal of television.
AD = Height of the television
DC = Width of the television.
Substitute all the values, we get;
⇒ 53² = h² + 45²
⇒ 2809 = h² + 2025
⇒ 2809 -2025 = h²
⇒ h² = 784

Read the instructions carefully!!!!
I will do the first example, by explaining how to graph it. Then you can do the second example.
\(f(x) = x^3-10x^2+28x-24\)
We start by determining the the x-intercepts, by letting y = 0:
\(x^3-10x^2+28x-24=0,\\\left(x-2\right)^2\left(x-6\right)=0,\\x=2,\:x=6\)
The x-intercepts of the graph are (2, 0) and (6, 0) respectively. Now we determine the y-intercepts by letting x = 0:
\(f\left(x\right)=\left(0\right)^3-10\left(0\right)^2+28\left(0\right)-24 = - 24\)
So the y-intercept is (0, -24). But remember we need one more point, as there has to be a transition between the x-intercepts. This is the minimum of the graph. To determine this, we take the derivative of the function, and then equate it to 0 to find the "critical points." :
\(\frac{d}{dx}\left(x^3-10x^2+28x-24\right)\\\\ =>\frac{d}{dx}\left(x^3\right)-\frac{d}{dx}\left(10x^2\right)+\frac{d}{dx}\left(28x\right)-\frac{d}{dx}\left(24\right)\\\\=> 3x^2-20x+28-0\\=> 3x^2-20x+28\)
Now we equate this to 0, and apply the quadratic equation. In this case we can actually factor it :
\(3x^2-20x+28=0,\\\left(x-2\right)\left(3x-14\right)=0,\\\\x=2,\:x=\frac{14}{3}\)
x = 2 is our maximum, or our x-intercept (2, 0). Therefore we have to take 14/3 as our minimum, and determine the y-value:
\(f\left(x\right)=\left(\frac{14}{3}\right)^3-10\left(\frac{14}{3}\right)^2+28\left(\frac{14}{3}\right)-24\\\\= -\frac{256}{27}\)
Minimum: (14/3, -256/27)

find the points (x,y) at which the curve x(t)=4cos(t),y(t)=4sin(2t) has a horizontal tangent.
The curve has horizontal tangents at the points (0,0) for all values of t. To find the points at which the curve has a horizontal tangent, we need to find the values of t that make the derivative of y(t) equal to zero.
First, we need to find the derivative of y(t):
y'(t) = 8cos(t)
Next, we set y'(t) equal to zero and solve for t:
8cos(t) = 0
cos(t) = 0
This occurs when t = π/2 or 3π/2.
Now, we can plug these values of t back into the original equations to find the corresponding points:
When t = π/2,
x(π/2) = 4cos(π/2) = 0
y(π/2) = 4sin(2(π/2)) = 0
So the point is (0,0).
When t = 3π/2,
x(3π/2) = 4cos(3π/2) = 0
y(3π/2) = 4sin(2(3π/2)) = 0
So the point is also (0,0).

Step-by-step explanation:
I just did the test
Answer:
The effect on the graph of the function f(x) = 2^x when f(x) is replaced with f(x − 3) is that it translates horizontally 3 units right.
When a function is replaced with f(x - c), where c is a positive constant, the graph of the function shifts horizontally c units to the right. Similarly, if c is negative, the graph shifts horizontally c units to the left.
Therefore, replacing f(x) with f(x - 3) in the function f(x) = 2^x shifts the graph of the function horizontally by 3 units to the right.

alice has two kids. one of them is a girl. what if the probability that the other one is a also a girl
The probability that the other child is also a girl, given that one of them is a girl, is 2/3 or approximately 0.6667.
To determine the probability that the other child is also a girl given that one of them is a girl, we need to consider the possibilities of the gender combinations for Alice's two children.
Let's denote the gender of the first child as G (girl) and B (boy), and the gender of the second child as G' and B'.
There are four possible combinations for the gender of the two children: GG, GB, BG, and BB.
However, we are given that one of the children is a girl. This eliminates the BB combination since we know both children cannot be boys.
Thus, we are left with three possible combinations: GG, GB, and BG.
Out of these three combinations, two of them involve at least one girl: GG and GB. This means there is a 2 out of 3 chance that the other child is a girl.
Therefore, the probability that the other child is also a girl, given that one of them is a girl, is 2/3 or approximately 0.6667.

The equation of line L₂, which is parallel to line L₁: y = 3 - 2x and passes through the point (5, 2), is y = -2x + 12.
Since line L₂ is parallel to line L₁, they have the same slope. The slope of line L₁ is -2. Therefore, the slope of line L₂ will also be -2.
We can use the point-slope form of a linear equation to find the equation of line L₂. The point-slope form is given by y - y₁ = m(x - x₁), where (x₁, y₁) is a point on the line and m is the slope.
We are given that line L₂ passes through the point (5, 2) and has a slope of -2. Substituting these values into the point-slope form, we have y - 2 = -2(x - 5).
Simplifying the equation, we get y - 2 = -2x + 10.
To express the equation in the form y = mx + c, where m is the slope and c is the y-intercept, we rearrange the equation as y = -2x + 12.
Therefore, the equation of line L₂ is y = -2x + 12.
