Which best explains why you can use multiplication to solve equations involving division?
A. Multiplication is easier to do than division.
B. Multiplication involves the same facts as division.
C. Multiplication is the inverse operation of division so it can undo division.
D. Multiplication involves commutative Property so it can undo division.
Answer:
C
Step-by-step explanation:
Write an equation for the line parallel to the given line that contains C.
C(2,8); y = - 2x + 1
y =
Okay!
Whenever a line is parallel to another, that means they ALWAYS have the same slope!
So the slope of our new line is -2 as well !
Now let's use point C (2, 8) to find the y-intercept!
This is easy! All we need to do is plug the point in our new equation!
Remember that in point C, 2 = x and 8 = y
Time to plug in all these numbers in y = mx + b
8 = -2 (2) + y intercept
→ the 8 is in the y's place
→the -2 is in the slope place
→2 is in the x place
Now we solve for the y-intercept using basic math!
8 = -2(2) + y-intercept
8 = -4 + y-intercept
8 + 4 = y-intercept
We did it! We found the y-intercept
The y-intercept is 12!
Now let's create our final equation ...
y = -2x + 12

Which ordered pair is a solution of the equation y+1=3(x-4)
Step-by-step explanation:
When x = 4 and y = -1,
(-1) + 1 = 3(4 - 4) = 0.
Hence (4, -1) is an ordered pair.
When x = 5 and y = 2,
(2) + 1 = 3(5 - 4) = 3.
Hence (5, 2) is an ordered pair.
Therefore the answer is C.
The polynomial x^4+px^3+qx^2+rx+6 is exactly divisible by each of (x-1), (x-2) and (x-3).
Find the values of p, q and r.
The remainder theorem says that a polynomial f(x) has a remainder of f(c) upon getting divided by x - c. So if
f(x) = x⁴ + p x³ + q x² + r x + 6
is divisible by x - 1, x - 2, and x - 3, then we have
f (1) = 7 + p + q + r = 0
f (2) = 22 + 8p + 4q + 2r = 0
f (3) = 87 + 27p + 9q + 3r = 0
Solve the system for p, q, r. You can eliminate r by substituting the first equation into the other two:
p + q + r = -7
8p + 4q + 2r = -22 → 6p + 2q - 14 = -22 → 3p + q = -4
27p + 9q + 3r = -87 → 24p + 6q - 21 = -87 → 4p + q = -11
Eliminate q by adding (-1) times the first equation to the second one, then solve for p :
- (3p + q) + (4p + q) = - (-4) + (-11)
-3p - q + 4p + q = 4 - 11
p = -7
Solve for q :
3p + q = -4 → 3 (-7) + q = -4 → q = 17
Solve for r :
p + q + r = -7 → -7 + 17 + r = -7 → r = -17

What is the check digit, d, for the credit card number shown below?
6424 9813 2720 008d
А. 1
B. 3
с. 5
D. 7
Answer:
A.1
Step-by-step explanation:
I did a check digit calculator and it said that this would be the check digit
The check digit is 1.
Step-by-step explanation:
The check digit on credit is calculated by the following step:
Mark each digit odd and even from the right side.Now multiply each digit at an even place with '2'.And if the number after multiplication is double-digit then add both the digit to obtain a single digit.Now add all the digits obtained in the previous step along with digits at odd places.To this sum obtained check by adding what digit it becomes next multiple of '10'.And that digit will be our check digit.Given:
The creditcard number: 6424 9813 2720 008d
To find :
Check digit,d
Solution:
6424 9813 2720 008d
Marking odd and even places from right side:
(e:even place,o:odd place)
e,o,e,o e,o,e,o e,o,e,o e,o,e,o
6 4 2 4 9 8 1 3 2 7 2 0 0 0 8 d
Multipling every even place digit with '2'.
12,4,18,2,4,4,0,16
If two digit number then add both digits to have single digit
12,4,18,2,4,4,0,16 → 1+2,4,1+8,2,4,4,0,1+6 → 3,4,9,2,4,4,0,7
Now adding all the digits obtained in prevoius step with digits at odd place:
(3+4+9+2+4+4+0+7)+(4+4+8+3+7+0+0)= 59
The next multiply of 10 can be obtained by adding 1 to '59' that is 60. So, the check digit will be'1'.
59+1 = 60
(60 is a multiple of the number '10'.)
The check digit is 1.

Answer: Original expression: 2x - 11 + 4x + 7 + 3(x-4)
Simplified: 9x - 16
Step-by-step explanation:
2x - 11 + 4x + 7 + 3(x-4) becomes 2x - 11 + 4x + 7 + 3x -12
Group like terms, then combine to simplify:
2x + 4x + 3x -11 + 7 - 12
2x + 4x + 3x = 9x
-11 -12 + 7 = =23+7= -16
Simplified expression: 9x - 16

Gabriel needs to purchase 15.2 gallons of gasoline for his truck, and 9.5 gallons of diesel fuel for his tractor. What is the total Gabriel will spend on gasoline and diesel fuel? Show your work.
Answer: $70.49
Step-by-step explanation:
Cost of gasoline = $2.75 per gallon
Cost of diesel fuel = $3.02 per gallon.
Since Gabriel needs to purchase 15.2 gallons of gasoline for his truck, the amount spent on gasoline will be:
= 15.2 × $2.75
= $41.80
Since he needs to spend 9.5 gallons of diesel fuel for his tractor, the amount spent on diesel fuel will be:
= 9.5 × $3.02
= $28.69
Total cost spent will be:
= $41.80 + $28.69
= $70.49

Left on together the cold and hot water faucets of a certain bathtub takes 6 minutes to fill the tub. If it takes the hot water faucet 15 minutes to fill the tub by itself , how long will it take the cold water faucet to fill the tub on its own ?
Answer:
10 minutes
Step-by-step explanation:
We have
1/ hot water faucet + 1/ cold water faucet = 1/6
= 1/15 + 1/c = 1/6
1/c = 1/6 - 1/15
Lowest Common Denominator
= 30
Hence:
1/c = 5 - 2/30
1/c = 3/30
1/c = 1/10
Cross Multiply
c = 10 minutes
Hence, it will take the cold water faucet 10 minutes to fill the tub on its own

If Danny gains 40 yards on the football field and then looses 15, What was the end result?
Answer:
25 yards
Step-by-step explanation:
Subtract 15 from 40.
Hope this helped :)
Answer:
25 yards
Step-by-step explanation:
Arithmetics
Imagine a straight line divided into 1-yard marks.
Danny runs for 40 marks and locates at mark 40.
He later loses 15 yards and his new position is 40 - 15 = 25 yards
Therefore, the end result is that Danny is at the 25-yard mark.

Find the volume of a rectangular prism with the width of x-1, a length of x+1 and a height of 2x-3.
Answer:
The Volume is equal to 2x^3-3x^2+2x-3
Step-by-step explanation:
Formula for the volume of a rectangular prism is V=WHL
We know that:
W=x-1
L=x+1
H=2x-3
So, V= (x-1)(x-1)(2x-3)
Simplify
(x^2+1)(2x-3)
2x^3-3x^2+2x-3
