Answer:
Box 1
Step-by-step explanation:
If you look carefully, you will notice that Boxes 2, 3, and 4 are all equations. We know this because they all have the "=" sign. On the other hand, Box 1 is an expression. We know this because it doesn't have an "=" sign. Therefore, Box 1 is the odd one out.

Answer: -2, 0, and 2.
Step-by-step explanation: You are given the relation R = {(-3, -2), (-3, 0), (-1, 2), (1, 2)} The domain of the relation are all possible inputs and the range of the relation are all possible outputs. So, the inputs are : -3,-1,1; and the outputs are : -2,0,2. As a result, the domain is : -3,-1,1; and the range is : -2,0,2.
the numbers that are in the range of the relation R are -2, 0, and 2.
To determine the numbers that are in the range of the given relation R, we need to identify the second components (y-values) of each ordered pair in the relation.
The range of a relation consists of all the unique y-values that are paired with x-values in the relation.
For the given relation R = {(-3, -2), (-3, 0), (-1, 2), (1, 2)}, the second components (y-values) are:
-2, 0, 2, 2.
To find the numbers that are in the range, we look for the unique values among these y-values:
-2, 0, 2.
Therefore, the numbers that are in the range of the relation R are -2, 0, and 2.

What are the solutions to this equation 2(6X² + 5x) =12
Answer:
x = - [tex]\frac{3}{2}[/tex], x = [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
Given
2(6x² + 5x) = 12 ( divide both sides by 2 )
6x² + 5x = 6 ( subtract 6 from both sides )
6x² + 5x - 6 = 0 ← in standard form
(2x + 3)(3x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = - [tex]\frac{3}{2}[/tex]
3x - 2 = 0 ⇒ 3x = 2 ⇒ x = [tex]\frac{2}{3}[/tex]

Answer:
x≥2
Step-by-step explanation:
First, write out the equation as you have it:
[tex]58-10x\leq20+9x[/tex]
Then, add [tex]10x[/tex] to both sides:
[tex]58-10x+10x\leq20+9x+10x\\58\leq20+19x[/tex]
Next, subtract [tex]20[/tex] from both sides:
[tex]58-20\leq20-20+19x\\38\leq19x[/tex]
Finally, divide both sides by [tex]19[/tex]:
[tex]\frac{38}{19}\leq\frac{19x}{19}\\2\leq x[/tex]
or
[tex]x\geq 2[/tex]
Therefore: the answer to this inequality/equation is: x≥2

Which statement about this system of equations is true? A. The system has no solution. B. The system has a unique solution at (0,6). C. The system has a unique solution at (0,-4). D. The system has infinitely many solutions.
Answer:
A. The system has no solutions
Step-by-step explanation:
Step 1: Check to see if the 2 lines share 1 slope
slope of blue line = [tex]\frac{y2-y1}{x2-x1} =\frac{7-6}{3-0}=\frac{1}{3}[/tex]
slope of red line = [tex]\frac{y2-y1}{x2-x1} =\frac{-3-(-4)}{3-0}=\frac{1}{3}[/tex]
Step 2: Realize that lines with the same slope never touch
We know lines with the same slope are parallel to each other so they won't collide
Step 3: Know what the question is asking you
When they ask for solutions to the system of equations they are asking you to find out where they intersect
Step 4: Find answer
Because we know this is a parallel line they will never intersect causing this system to never have an answer or solution
Therefore the answer is A. The system has no solutions
Answer:
[tex]\huge \boxed{\mathrm{Option \ A}}[/tex]
Step-by-step explanation:
For the system of equations to have solutions, the two equations have to intersect on the graph.
The two lines on the graph never intersect, therefore there are no solutions for the system of equations.

the sum of a two digit number is 4. if the order of the digits are reversed, the result is a number that exceeds the original number by 18. find the number
Answer:
13
Step-by-step explanation:
Hello, we can write a two digit number 'ab' as 10 * a + b, where a and ba are two integer between 0 and 9.
For instance, 54= 50 + 4 = 5 *10 + 4, a = 5 b = 4, right?
The sum of a two digit number is 4.
a + b = 4
If the order of the digits are reversed, the result is a number that exceeds the original number by 18.
10b + a = 10a + b + 18
9b = 9a + 18
b = a + 2
We can replace in the first equation,
a + a + 2 = 4
2a = 2
a = 1
and then, b = 3
So the number is 13.
thank you

(8x2 + 8x) – (-9x2 + 8x)
Answer:
17 x^2
Step-by-step explanation:
(8x^2 + 8x) – (-9x^2 + 8x)
Distribute the minus sign
8x^2 + 8x + 9x^2 - 8x
Combine like terms
17 x^2 +0x
17x^2
Answer:
17x^2
Step-by-step explanation:
(8x^2 + 8x) – (-9x^2 + 8x) =
The parentheses on the left side are unnecessary, so just remove them.
= 8x^2 + 8x – (-9x^2 + 8x)
To remove the right set of parentheses, distribute the negative sign.
= 8x^2 + 8x + 9x^2 - 8x
Now combine like terms.
= 8x^2 + 9x^2 + 8x - 8x
= 17x^2

The first two terms of an arithmetic progression are 27 and 24 respectively. How many terms of the progression are to be added to get - 30?
Answer:
20 terms
Step-by-step explanation:
Given AP with the first two terms:
a₁= 27 and a₂=24Common difference:
d= 24-27 = -3To find
n for which Sₙ= -30SolutionSₙ = 1/2*n*(a₁+aₙ) = 1/2n(a₁+a₁+(n-1)d) =1/2n(27+27+(n-1)(-3))= 1/2n(54 - 3n + 3) = 1/2n(57 - 3n)Since Sₙ = -30
1/2n(57 - 3n) = -3057n - 3n² = -6019n - n²- 20 = 0n² -19 n -20= 0Solving the quadratic equation we get:
n =20So the sum of 20 terms will add up - 30
Will had $4355.19 in his checking account. He writes checks for $1,204.90 and $890.99. How much does Will have left in his account?
Answer:
$2259.30
Step-by-step explanation:
If will started with 4355.19$ in his checking account and wrote two checks, that mean he has taken money out of his account (subtraction operation). We can represent this with the expression:
4355.19 -1204.90 - 890.99
Using this expression, we can simplify to find the remainder of money Will has in his account once the two checks clear.
4355.19 - 1204.90 - 890.99
= 4355.19 - (1204.90 + 890.99)
= 4355.19 - (2095.89)
= 2259.30
So once the two checks Will wrote clears, he will have $2259.30 left in his checking account.
Cheers.
Answer:
$2259.28
Step-by-step explanation:
Will have $4355.19
Check writes ($1204.90+$890.99)
= $2098.89
Will have left in his account ( $4355.19 - $2098.89)
= $2259.28 (ans.)

Step 2: Add 6x to both sides.
−8x+4+6x=−6x−14+6x

Answer:
2
Step-by-step explanation:
This is our equation-
-4(2x-1)=-6(x+2)
We are trying to isolate x in a side, but first, we must multiply the numbers in between the brackets. A negative number multiplied by a positive number gives a negative number, and a negative times a negative is positive, so-
-8x·4=-6x+(-12)
Now we have to multiply -8x times 4
-32x=-6x-12
Now we isolate x-
-24x=-12
We divide and get the final result of x=2

Find two consecutive even integers such that 5 times their sum is 26 more than their product. (Enter your answers as a comma-separated list.)
Answer:
The two consecutive even integers = (4, 6)
Step-by-step explanation:
We are asked in the question to find two consecutive even integers such that 5 times their sum is 26 more than their product.
Two consecutive even integers is represented as: x, x + 2
Five times their sum is 26 more than their products
5( x + x + 2) = [x × (x + 2)] + 26
5( 2x + 2) = (x² + 2x) + 26
10x + 10 = (x² + 2x ) + 26
x² + 2x + 26 - 10x - 10 = 0
x² - 8x + 16 = 0
We factorise
x² - 4x - 4x + 16 = 0
(x² - 4x) -(4x + 16) = 0
x(x - 4) -4(x - 4) = 0
(x - 4)(x - 4) = 0
(x - 4)²
Hence
x - 4 = 0
x = 4
Since, we know that two consecutive even integers = (x , x + 2)
First even integer = x = 4
Second even integer = x + 2 = 4 + 2
= 6
Therefore, the two consecutive even integers = (4, 6)
