Using creamers rule of determinants, we have;
D =
|1 1|
|2 3|
Thus; D = (1 × 3) - (1 × 2)
D = 1
Dx =
|2 1|
|4 3|
Dx = (2 × 3) - (1 × 4)
Dx = 2
Dy =
|1 2|
|2 4|
Dy = (1 × 4) - (2 × 2)
Dy = 0
Thus;
x = Dx/D = 2/1
x = 2
y = Dy/D = 0/1
y = 0

The volume of Cube A is 64 cubic inches. The face of Cube B has an area of 81 square inches. Which cube has a greater side length?
The side length of Cube A is inches. The side length of Cube B is
(Simplify your answers.)
inches Cube
has a greater side length.
Answers
The answer to this question is:
Cube B has greater side length.
We know that the volume of cube = ( a )³
(where a represents the cube's sides length.)
Given that:
Volume of Cube A = 64 cubic inches = 64 in³
Volume of Cube B = 81 cubic inches = 81 in³
Length of side by cube = ∛Volume
Length of side of Cube A = ∛64 = ∛ 2*2*2*2*2*2*
= 2*2
= 4 inches
Length of side of Cube B = ∛81 = ∛ 3*3*3*3
= 3√3
=3*1.732 = 5.196 inches
Length of side of cube A < Length of side of cube B
4 inches < 5.196 inches
Thus, Cube B has greater side length.
Therefore, Cube B has greater side length.

Answer: Apple price = Rs 75 per kg & Orange price = Rs 45 per kg
Step-by-step explanation:
Creative Section- A
a) 4kg apples + 6 kg oranges = Rs 570
3kg apple price = 5 kg orange price
Let, apple = x , orange = y
Now, 4x+6y= 570
3x=5y ⇒ 3x-5y= 0
Subtract two equations,
x+11y=570
⇒ x + (33x/5) = 570
⇒ 7.6x = 570
⇒ x = 75, y= 45
Apple price = Rs 75 per kg
Orange price = Rs 45 per kg

Graph the logarithmic function below by moving the
key point.
y = log₂ (x)
You can only graph integer points
Answers
To graph the logarithmic function y = log₂(x), we can use the key point (1,0) and the fact that the logarithmic function is the inverse of the exponential function y = 2ˣ.
Starting at the key point (1,0), we can move to the right by increasing x by a factor of 2, since log₂(2) = 1. This takes us to the point (2,1). Similarly, we can move to the right by a factor of 2 again to get to the point (4,2), and then to (8,3), (16,4), and so on.
If we instead move to the left from the key point (1,0) by a factor of 2, we get to the point (1/2, -1), since log₂(1/2) = -1. We can continue moving to the left by dividing x by 2 to get to (1/4, -2), (1/8, -3), and so on.
The given graph of y = log₂(x) using only integer points.
The graph is symmetric about the line x=1, since log₂(x) = log₂(1/x) = -log₂(x).

[tex]\left \{ {{x+y=5} \atop {x-2y=2}} \right.[/tex]
Here we have 2 equations in one system.
System of Equations/Simultaneous Equations are for finding the intercepts of both graphs.
We can solve these Simultaneous Equations in many ways. However, I'll be solving by substitution.
To solve by using substitution, we need to move either x or y to the another side. I'll move x term to another side for the first equation. (We'll substitute the first equation in the second.)
[tex]\left \{ {{y=-x+5} \atop {x-2y=2}} \right.[/tex]
Now we substitute y = -x+5 in x-2y = 2
[tex]x-2(-x+5)=2\\[/tex]
Then distribute -2 in (-x+5) | Note that multiplying the negative will get positive. |
[tex]x-2(-x+5)=2\\x+2x-10=2\\3x=2+10\\3x=12[/tex]
We should get this. When we get this, we move 3 to divide 12 (Opposite when moving to another side so from plus to minus and from multiply to divide.)
[tex]x=4[/tex]
But we are not done yet. We have to find the y-value. After all they are two variables equations.
If we want to find the y-value then we have to substitute x = 4 in any given equations. I'd suggest to substitute in the equation that doesn't have a coefficient with high value.
So I'll be substituting in x + y = 5 instead.
Substitute x = 4 in x + y = 5
[tex]4+y=5\\y=5-4\\y=1[/tex]
Thus, we get both x and y value. Answer in either coordinate point or writing form.
Therefore, the answer is
x = 4 when y = 1 or (4,1)
Both works. Hope this helps.

√25 is 5. Multiply your 20 and 5 together to get 100, and then put your √6 next to the 100 since it cannot be added or multiplied since they are not like-terms.

2. Grant works as a salesperson at a seasonal market. During the Christmas season, he
gets a 15 percent commission on every tree he sells. If he sold 12 trees today, with an
average sale price of $35 per tree, what amount of commission will he make?
Answers
Grant will make $63 commission on 12 trees he sold.
Given that, Grant works as a salesperson at a seasonal market. He gets a 15 percent commission on every tree he sells. If he sold 12 trees then we have to calculate the amount of commission he will get if the average sales price of a tree is $35.
So, first we will calculate the amount of commission Grant will get if he sold one tree.
∴ The commission on one tree will be equals to 15 percent on the sales price of a tree i.e., $35.
⇒ 15% of $35
= 15/100 x 35
= 5.25
Therefore, Grant will get $5.25 commission on selling one tree.
He sold 12 trees on that day. So, the total amount of commission he will get on 12 trees will be equal to,
= 12 x 5.25
= 63
Therefore, $63 is the amount of commission Grant will made on the sale of 12 trees.
