Answer:
fish 1 dollar
castle 6 dollars
Step-by-step explanation:
4x + y = 10
4x + 2y = 16
Multiply the first equation by -1
- 4x - y = -10
4x + 2y = 16
------------------------
0x +y = 6
y = 6
This means the castle costs 6 dollars
Substitute this into the first equation
4x+y =10
4x+6=10
Subtract 6 from each side
4x+6-6=10-6
4x=4
Divide by 4
4x/4=4/4
x=1
This means each fish costs 1 dollar
So x=1 the answer is 1

Explanation:
A parallelogram is a four-sided polygon with opposite sides that are both parallel and equal in length. It also has opposite angles that are equal. In other words, if you take any two opposite sides of a parallelogram and extend them indefinitely in both directions, they would never intersect.
Parallelograms have several properties:
Opposite sides are parallel and equal in length.Opposite angles are equal.Consecutive angles are supplementary, meaning they add up to 180 degrees.Diagonals bisect each other.Precalculus Homework help please.

I need to find the missing numbers
Answer:
b11 = -14
b12 = 9
b13 = 8
Step-by-step explanation:
* Lets revise some notes to solve the problem
- Any matrix has a dimension m × n, where m is the number of rows
and n the number of columns
- We can add matrices with same dimensions
* Now lets solve the problem
∵ [tex]B+\left[\begin{array}{ccc}15&-7&4\\0&1&2\end{array}\right]=\left[\begin{array}{ccc}1&2&12\\4&0&2\end{array}\right][/tex]
- Let [tex]B=\left[\begin{array}{ccc}b11&b12&b13\\b21&b22&b23\end{array}\right][/tex]
∴ [tex]\left[\begin{array}{ccc}b11&b12&b13\\b21&b22&b23\end{array}\right]+\left[\begin{array}{ccc}15&-7&4\\0&1&2\end{array}\right]=\left[\begin{array}{ccc}1&2&12\\4&0&2\end{array}\right][/tex]
- Lets add and find the missing
* Lets start with the first rows
∵ b11 + 15 = 1 ⇒ subtract 15 from both sides
∴ b11 = -14
∵ b12 + -7 = 2 ⇒ add 7 to both sides
∴ b12 = 9
∵ b13 + 4 = 12 ⇒ subtract 4 from both sides
∴ b13 = 8
* Now lets start with the second rows
∵ b21 + 0 = 4
∴ b21 = 4 ⇒ given
∵ b22 + 1 = 0 ⇒ subtract 1 from both sides
∴ b22 = -1 ⇒ given
∵ b23 + 2 = 2 ⇒ subtract 2 from both sides
∴ b23 = 0 ⇒ given
An Angle whose measure is 40 is in standard position. In which quadrant does the terminal side of the angle fall?
ANSWER
First quadrant
EXPLANATION
An angle in standard position starts measuring from the positive x-axis anticlockwise.
Since 40° is less than 90°, it's terminal side will fall within the first quadrant.
Hence the terminal side of a 40° is in the first quadrant.

Answer:
Abraham Lincoln, the 16th president of the United States, was born on February 12, 1809 and died at the age of 56 on the 4th day of March 1861. Lincoln was the president of the United States for four years from 1861 to 1865. Lincoln was born in Hardin County in the state of Kentucky in a small cabin that only had one room. His parents, Thomas Lincoln and Nancy Hanks were farmers who had a large track of land that measured 348 acres on which their cabin was situated. His parents were uneducated, however.
Lincoln’s political career began in 1832 when he created a political campaign for a political party known as the Whig Party. This party was based on efforts that sought to improve navigation on the neighboring river. Ten years later, Lincoln married the love of his life, Mary Todd, with whom he had four sons. Unfortunately, only one of his four sons did not survive into adulthood. Lincoln’s participation in active national politics took a turn for the better in 1842 when he campaigned and was elected to the US House of Representatives.

Step-by-step explanation:
Kyle drew 4 polygons labeled A,B,C, and D. Figure A has twice as many sides as Figure B. Figure B has 3 vertices. Figure C has half as many sides as figure D. Figure D has 8 vertices. Name each polygon Kyle draw.
Answer:
Figure A - hexagon
Figure B - triangle
Figure C - rectangle
Figure D - octagon
Step-by-step explanation:
If figure B has 3 vertices (angles), then that means it is a triangle (3 sides)
So that means figure A has 6 sides, (hexagon)
And figure D has 8 vertices, so 8 sides (octagon)
And if C has half as many, that would be 4 (rectangle)
How much more will 22,000 earn in interest than 14000 if both are invested in savings accounts with apys of 5.4% for a year?
Answer:
$432 more are earned by 22,000 than 14,000 if invested with apys of 5.4% for a year
Step-by-step explanation:
Total = [tex]P*(1+r)^t[/tex]
where P=Principal amount
r= rate
t= time
Using this formula for P= 22,000 and r = 5.4% or 0.054 and t= 1
Total = [tex]22,000*(1+0.054)^1[/tex]
Total = [tex]23,188[/tex]
Interest earned = 23,188 -22,000
Interest earned = 1,188
Using this formula for P= 14,000 and r = 5.4% or 0.054 and t= 1
Total = [tex]14,000*(1+0.054)^1[/tex]
Total = [tex]14,756[/tex]
Interest earned = 14,756 -14,000
Interest earned = 756
AS interest earned by 22,000 is 1,188 while interest earned by 14,000 is 756
so, 1,188 - 756 = 432.
So, $432 more are earned by 22,000 than 14,000 if invested with apys of 5.4% for a year
Answer:

13. Write a function with a zero of 1/2. Explain how you know.
Answer:
The function is [tex]f(x)=2x-1[/tex]
Step-by-step explanation:
If a function has a zero of [tex]\frac{1}{2}[/tex].
The we can write [tex]x=\frac{1}{2}[/tex].
We need to work backwards to obtain the function:
We multiply through by 2 to get:
[tex]2x=1[/tex].
This implies that:
[tex]2x-1=0[/tex]
Hence a function with such zero is [tex]f(x)=2x-1[/tex]
Answer:
The function is [tex]f(x)=4x-2[/tex]
Step-by-step explanation:
That a function has a zero at a certain number x means that [tex]f(x)=0[/tex]
Let's see an example,
If we have [tex]f(x)=x+2[/tex] (this is what we call function)
and we choose any value for the x,
x = 3
Now we replace it in our function
[tex]f(3)=3+2[/tex]
[tex]f(3)=5[/tex] (this is the image of 3)
Now if we say that x = -2, and replace it in our function
[tex]f(-2)=(-2)+2[/tex]
[tex]f(-2)=0[/tex] , this means that our function has a zero at x = -2
We can find the zeros of our function equaling it to zero and clearing the x, let's see
[tex]x+2=0[/tex]
[tex]x=-2[/tex] this means that our function has a zero at x = -2
To find a function that has a zero at [tex] \frac{1}{2}[/tex] , let's think that the result must be [tex]f(x)=0[/tex]
If we have 4 and multiply it by 1/2.
[tex]4)(\frac{1}{2})=2[/tex], now we subtract 2 from this result
[tex]-2 = 0[/tex] , the complete process would be
[tex]4)(\frac{1}{2})-2=0[/tex], we said that [tex] \frac{1}{2}[/tex], then
[tex]4x-2[/tex], now we write it as a function
[tex]f(x)=4(x)-2[/tex] we know that by replacing the x by 1/2 the result will be zero, which means that [tex] \frac{1}{2}[/tex] is zero of this function

For circle O, mCD=125° and m
CA is a diameter of the circle, so [tex]m\widehat{AC}=180^\circ[/tex], which means [tex]m\angle AOB=m\angle AOD=m\widehat{AD}=180^\circ-m\widehat{CD}=55^\circ[/tex]. Then [tex]m\boxed{\angle ABO}=90^\circ-55^\circ=35^\circ[/tex].
This means [tex]m\angle CBO=55^\circ-35^\circ=20^\circ[/tex]. Also, if [tex]m\angle AOB=55^\circ[/tex], then [tex]m\angle BOC=180^\circ-55^\circ=125^\circ[/tex], which in turns tells us that [tex]m\boxed{\angle BCO}=180^\circ-20^\circ-125^\circ=35^\circ[/tex].

the substitution method.
y = 3x + 9
y = 5x – 3
I need the answer for X and Y
Answer: Please Mark Brainliest :) !!
The answer is x= 6 and y= 27.
Step-by-step explanation:
3x + 9 = 5x + 3
-2x + 9 = -3
y = 5x -3
x = 6
y = 5x -3
y = 5(6) -3
y = 27
First, when solving for x, you would need to make one of the equation into standard form, which would be Ax + By = C. So, I'm going to use y = 5x -3.
y = 5x - 3 || subtract -5x on both sides from the equal sign
5x + y = -3 || there you have one equation in standard form
Now, all you have to do now is substitute the y-intercept form equation into the standard form equation. As you can see, you would substitute the y-intercept form into the y in the standard form equation.
5x + y = -3
5x + 3x + 9 = -3 || combine like terms
8x + 9 = -3 || subtract 9 on both sides from the equal sign
8x = 6 || divide by 8 on both sides from the equal sign
x = 0.75 || final answer for x
Then for solving y, take any equation in y-intercept form and substitute with the x in the equation, which I'm going to use y = 3x + 9 in this case.
y = 3x + 9 || substitute with x
y = 3 (0.75) + 9 || multiply 3 and 0.75
y = 3.75 + 9 || add 3.75 and 9
y = 12.75 || final answer for y
Thus, x = 0.75 and y = 12.75.

Which of the following uses the Distributive Property to determine the product 12(185) Question 6 options: a) 12(100) + 12(13) b) 12(18) + 12(5) c) 12(1) + 12(8) + 12(5) d) 12(100) + 12(80) + 12(5)
Answer:
d) 12(100) + 12(80) + 12(5)
Step-by-step explanation:
According to the distributive property, if a,b, c, and d are real numbers, then
a(b+c+d)=ab+ac+ad
We want to find the product 12(185).
We can expand 185 as 100+80+5
Our product then becomes;
[tex]12(185)=12(100+80+5)[/tex]
We expand using the distributive property to get;
[tex]12(185)=12(100)+12(80)+12(5)[/tex]
The correct choice is D
Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
12(185)
Firstly we can write
185=100+80+5
So, it will be rewritten as
12(100+80+5)
As we know that distributive law that implies
a(b+c+d)=ab+ac+ad
So, according to distributive law, it becomes,
12(100)+12(80)+12(5)
Hence, option 'd' is correct.
