Answer:
B
Step-by-step explanation:
Given
(4x + 3)(3x - 4)
Each term in the second factor is multiplied by each term in the first factor, that is
4x(3x - 4) + 3(3x - 4) ← distribute both parenthesis
= 12x² - 16x + 9x - 12 ← collect like terms
= 12x² - 7x - 12
The coefficient of the x- term is - 7 → B
Make M the subject of the expression T=WPLM² - (M-S)²
Answer:
The answer is
[tex]M = \sqrt{WPLM^{2} - T } + S[/tex]Step-by-step explanation:
First move (M-S)² to the right side of the equation
That's
(M-S)² = WPLM² - T
Find the square root of both sides
That's
[tex]M-S = \sqrt{WPLM^{2} - T }[/tex]Move S to the right side of the equation to make M stand alone
We have the final answer as
[tex]M = \sqrt{WPLM^{2} - T } + S[/tex]Hope this helps you
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.

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)

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:
[tex]2 \frac{59}{72}[/tex]
Step-by-step explanation:
3 3/8 = 3 + 3/8 = 24/8 + 3/8 = 27/8
then:
-5/9 + 3 3/8 = -5/9 + 27/8
= -40/72 + 243/72
= 203/72
203/72 = 144/72 + 59/72 = 2 + 59/72
= 2 59/72
Express the interval set builder notation
Answer:
{x | -1 < x ≤ 2}
Step-by-step explanation:
Interval given in the notation of (a, b) denotes,
Upper limit at 'b' and lower limit at 'a'
Sign () denotes the interval between a and b exclusive of the numbers a and b.
Interval given as [a, b] represents,
a = lower limit
b = higher limit
Notation of [] show the interval inclusive of these numbers.
Given set in the question is (-1, 2]
Here (-1) is the lower limit and 2 is the upper limit.
(] notation shows exclusive of (-1) and inclusive of 2.
Therefore, solution set in set-builder notation will be {x | -1 < x ≤ 2}
The number of birds (b) in a park increases when the number of dogs in the park (d) decreases. Write the correct equation for this scenario, and solve for the number of birds when there are 10 dogs.
Complete question :
The number of birds (b) in a park increases when the number of dogs in the park (d) decreases. Write the correct equation for this scenario, and solve for the number of birds when there are 10 dogs.
Dogs(d) - - birds(b)
40 - - - - - - 10
50 - - - - - - 8
Answer:
b = k/d ; 40
Step-by-step explanation:
From the table:
Dogs(d) - - birds(b)
40 - - - - - - 10
50 - - - - - - 8
The number of birds(b) in a park increases when the number of dogs (d) decreases.
Hence we can infer that an inverse relationship exists between them.
Number of birds(b) ∝ 1 / number of birds
b ∝ 1 / d
b = k/d
k = (b × d)
Where k is the proportionality constant
When d = 40, b = 10
Solve for k
k = (40 * 10)
k = 400
Therefore, number of birds(b), when there are 10 dogs;
b = k/d
k = 400, d = 10
b = 400 / 10
b = 40
40 birds when dogs = 10
Create a table of points from the equation f(x)=3x2−8x+2.
Answer:
(See explanation below for further details)
Step-by-step explanation:
A second order polynomial (quadratic function) can be well represented with at least three distinct points. Let is take five equidistant different points:
x = 0
[tex]f(0) = 3\cdot (0)^{2}-8\cdot (0) +2[/tex]
[tex]f(0) = 2[/tex]
x = 1
[tex]f(1) = 3\cdot (1)^{2}-8\cdot (1)+2[/tex]
[tex]f(1) = -3[/tex]
x = 2
[tex]f(2) = 3\cdot (2)^{2}-8\cdot (2)+2[/tex]
[tex]f(2) = -2[/tex]
x = 3
[tex]f(3) = 3\cdot (3)^{2}-8\cdot (3)+2[/tex]
[tex]f(3) = 5[/tex]
x = 4
[tex]f(4) = 3\cdot (4)^{2}-8\cdot (4) + 2[/tex]
[tex]f(4) = 18[/tex]
The table of points from the equation [tex]f(x) = 3\cdot x^{2}-8\cdot x +2[/tex] is:

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.

Answer:
This is not a function.
Step-by-step explanation:
A function by definition will map one element of the domain to one element of the range. In this example, we would need one element of A to match one element of B for all elements of A.
Note, there are two elements in set A that map to one element in set B, while one element in set B has no mapping from any element in set A.

the market price of an article is rs 6000 13 percentage vat is levied after allowing 15 percent discount an the article what will be the price of the article find it also find the amount of vat
Answer:
[tex] \boxed{ \bold{ \sf{Price \: of \: the \: article = \: Rs \: 6678.3}}}[/tex]
[tex] \boxed{ \bold{ \sf{Vat \: amount = \: \: Rs \: 768.3}}}[/tex]
Step-by-step explanation:
Given,
Marked Price ( MP ) = Rs 6000
Vat percent = 13 %
Discount percent = 15%
▪️Finding the discount amount
Discount amount = Discount % of MP
= 15 % of 6000
= Rs 900
▪️Finding the selling price
Selling price ( SP )= Marked price - Discount amount
= Rs 6000 - Rs 900
= Rs 5910
▪️Finding the vat amount
Vat amount = Vat % of SP
= 13 % of 5910
= Rs 768.3
▪️Finding SP with VAT
SP with vat = SP + vat amount
= Rs 5910 + Rs 768.3
= Rs 6678.3

15-8x Choose ALL of the statements that are TRUE. The factors are 8 and x. The coefficient is -8. The constant is -8. The terms are 15 and -8x. The coefficient is 15. The constant is 15.
Explanation:
The coefficient is the number just to the left of the variable. So that's why -8 is the coefficient for -8x. This is the variable term while 15 is the constant (it has no variable multiplied with it). The two terms are 15 and -8x since we can write 15-8x as 15+(-8x). Terms are separated by a plus sign.
