Solve the system of equations using subtraction. y = -2x + 1 4x + 2y = -3 a. Infinity many solutions b. No solution c. (0,-5) d. (-5,0)
Answers
Given:
The given system of equation is:
[tex]y=-2x+1[/tex]
[tex]4x+2y=-3[/tex]
To find:
The solution of given system of equations using subtraction.
Solution:
We have,
[tex]y=-2x+1[/tex] ...(i)
[tex]4x+2y=-3[/tex] ...(ii)
First equation can be rewritten as
[tex]2x+y=1[/tex] (Adding 2x on both sides)
[tex]4x+2y=2[/tex] ...(iii) (Multiplying both sides by 2)
After subtracting (ii) from (iii), we get
[tex]4x+2y-(4x+2y)=2-(-3)[/tex]
[tex]4x+2y-4x-2y=2+3[/tex]
[tex]0=5[/tex]
This statement is false because [tex]0\neq 5[/tex]. It means, there is no value of x and y for which the given system of equations are true.
Therefore, the given system of equations has no solution and the correct option is b.

Let C represent the cost in dollars and R represent the revenue in dollars. What is the break-even point? Use a table to help if necessary.
C=24x+80
R=44x
Break Even point (_ , _)
Answers
Answer:
Please check the explanation.
Step-by-step explanation:
Given
C=24x+80
R=44x
To determine
What is the break-even point?
Given that
C represents the cost in dollars
R represents the revenue in dollars.
At the break-even point Cost (C) equals Revenue (R), so
R = C
44x = 24x+80
44x-24x = 80
20x = 80
divide both sides by 20
20x/20 = 80/20
x = 4
Thus, at x = 4 the value of Cost (C) equals Revenue (R).
i.e.
C = 24x+80 = 24(4)+80 = $176
R = 44x = 44(4) = $176

Answers
Hi. you've asked an incomplete question. However, I provided some explanation about algebraic expressions and numerical expression.
Step-by-step explanation:
First, we may wonder: What is a numerical expression? In simple words, they are mathematical expressions that contain numbers and operations (like +, -, ÷, ×).
For example, 7+70, 90-10, 60÷10, 5×4 are numerical expressions.
While an algebraic expression on the other hand is a mathematical expression that contains at least one variable.
Variables are letters or symbols (like x, y, p, q, etc) that represent an unknown number or value in a mathematical expression.
For example, 7x+70, 90y-10 are algebraic expressions since they contain at least one variable.

Best Buy is having a HUGE sale. All items are 60% off. How much will you pay for a tv that originally cost $1200 including 5% sales tax?
Answers
Answer:
$480
Step-by-step explanation:
According to the problem, calculation of the given data are as follows,
Original cost including sales tax = $1,200
Discount = 60%
So, we can calculate the cost of TV after discount by using following formula:
Cost of TV after discount = $1,200 - ( $1,200 × 60%)
= $1,200 - $720
= $480
Hence, Cost of TV after discount is $480.

if y=3x^3+x^2-5 and z=x^2-12 what polynomial is equivalent to 2(y+z)
Answers
Answer:
2y + 2z
6x³+2x²-10 + 2x²-24
6x³+4x²-34 ■
Step-by-step explanation:
The polynomial which is equivalent to 2 (y + z) is 6x³ + 4x² - 34.
What is Polynomial?A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number. The exponents of the variables in any polynomial have to be a non-negative integer.
Here, y = 3x³+x²-5 and z = x²-12
Now,
2 ( y + z ) = 2 ( 3x³+x²-5 + x²-12 )
2 ( y + z ) = 2 ( 3x³ + 2x² - 17 )
2 ( y + z ) = 6x³ + 4x² - 34
Thus, the polynomial which is equivalent to 2 (y + z) is 6x³ + 4x² - 34.

Natalie is making costumes each costume has 4 buttons that costs 3 cents and a zipper costs 7 cents how much does she spend on buttons and a zipper for each costume?
Answers
Answer:
19 cents
Step-by-step explanation:
Natalie buys 4 buttons at 3 cents each. She also buys 1 zipper at 7 cents
We are to find the total amount that she spends for each costume
I converted cents to dollars.
4 buttons at 3 cents = 4x0.03 (3 cents is 0.03 dollars)
= 0.12
The zipper = 7 cents = 0.07 dollars
The total amount she spent = 0.12+ 0.07
= 0.19 dollars = 19 cents
Therefore she 19 cents in total for each costume

Determine the coordinates of the midpoint of the line
segment with endpoints R(6,-2) and S(-3,-2).
O (1,2)
O (1.5, 2)
O (1.5, -2)
(3,-2)
Answers
Answer:
(1.5, -2)
Step-by-step explanation:
First subract -3 from 6 to find the total distance of the line segment.
6 - (-3)
Two negatives make a positive
6 + 3
9 units distance
Knowing this, the midpoint is 4 1/2 units away from either end. (1/2 * 9 = 9/2 = 4 1/2 units) Either add 4.5 to -3, or subtract 4.5 from 6 (keep the -2 though, as this line is straight!) to get the coordinates of the midpoint.
-3 + 4.5
-3 + 3 + 1.5
(1.5, -2)
6 - 4.5
6 - 4 - 0.5
2 - 0.5
(1.5, -2)
The midpoint of segment RS is (1.5, -2).
