Step-by-step explanation:
The process of elimination is a method of solving a system of equations. This process includes manipulating a system of equations such that one variable present in both equations has its coefficients as additive inverses. When one adds the equation, this variable will cancel, one can solve for the other variable using inverse operations, and then back solve for the eliminated variable.
[tex]\left \{ {{x+y=11} \atop {x-y=-5}} \right.[/tex]
As one can see, the coefficients of variable (y) are already additive inverses of each other (1), (-1), therefore, one can add the systems right away.
[tex]\left \{ {{x+y=11} \atop {x-y=-5}} \right.[/tex]
[tex](x)+(y)+(x)+(-y)=(11)+(-5)[/tex]
Simplify,
[tex]2x=6[/tex]
Inverse operations,
[tex]x=3[/tex]
Backsolve for (y), substitute the value of (x) into one of the original equations to find the value of (y),
[tex]x+y=11\\[/tex]
Substitute,
[tex](3)+y=11[/tex]
Inverse operations,
[tex]y=8[/tex]

What are the coordinates of the turning point of the parabola whose equation is y=-x^2+4x+1
PLEASEEE ANSWERRRRRR
Answer:
The maximum of the parabola lands at (2,5).
The coordinates of the turning point of the parabola whose equation is y=-x²+4x+1 are (2, 5)
What is Coordinate system?A coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points.
The equation of Parabola is y=-x²+4x+1
The turning point (vertex) is the point where the derivative is equal to zero.
y=-x²+4x+1
Differentiate the equation
dy/dx=-2x+4
Now equate dy/dx with zero
dy/dx=0
-2x+4=0
-2x=-4
x=2
Now put x value in the equation
y=-(2)²+4(2)+1
y=-4+8+1
y=5
Hence the coordinates of the turning point of the parabola whose equation is y=-x²+4x+1 are (2, 5)

A rectangle has a area of 30 square units and a width of 6. Find its length
Answer:
Step-by-step explanation:
If the overall area of the square is 30 units with a width of 6 units, all you need to do is divide 30 by 6. Or, if you add 6 till you get 30, which is much simpler.
If we start from six and count up till we get to/close to 30 without passing the number, we can do this.
6, 12, 18, 24, 30
Right on the dot of thirty! How lucky! Now we notice that while counting up, there were 5 variables (Don't know if I'm using this word correctly :\) of thirty in total. Then, if you want to double check, multiply 5 by 6 to get thirty and show proof that your answer is correct!
Good job! You survived the maths!
Anyways, here's the answer: The missing length of the 30 unit square is 5.
Answer:
5 is its length, divide the given length to the total area to get your missing length
Whenever given an area and a length or a width either ONE of those, you always divide the given length. Why? Because the number you get from dividing will make sense! That number you got from dividing times the give length will equal your area! Which is why you divide your given length to your total area.

−8x+4y=24
−7x+7y=28
x=?
y=?
Answer:
x = -2y = 2Step-by-step explanation:
You want the solution to the system of equations ...
-8x +4y = 24-7x +7y = 28SolutionWe notice that each of these equations has a leading minus sign, and has coefficients that have a common factor. We can multiply by -1 to make the leading coefficient positive, and we can divide by the common factor. Doing this puts the equations in standard form:
2x -y = -6
x -y = -4
Subtracting the second equation from the first gives ...
(2x -y) -(x -y) = (-6) -(-4)
x = -2
Rearranging the second equation to find y, we have ...
y = x +4
y = -2 +4 = 2
The solution is (x, y) = (-2, 2).

At a sale this week, a suit is being sold for $296.40. This is a 62% discount from the original price. What was the original price?
Answer:
Rounded: $478.06
Step-by-step explanation:
Set up an equation:
Variable x = original price
62/100 = 296.40/x
Cross multiply
62 × x = 100 × 296.40
62x = 29,640
Divide both sides by 62:
x = 478.064516....
Round to nearest cent (hundredths place):
x = 478.06
Check your work (using the rounded estimate will be close to $296.40 but not exact because it is rounded; once you round your answer and it should match):
478.06 × 62%
Convert the percentage into a decimal:

Make x the subject of the formula: m=x−3b
Answer:
x = m + 3b
Step-by-step explanation:
add 3b to each side
x = m + 3b
Answer:
x=m+3b
Step-by-step explanation:
Hi there!
Our goal to make x the subject of the formula is to isolate x on one side and have everything else on the other side
here's the given formula:
m=x-3b
-3b is on the same side as x, which we don't want
add 3b to both sides (-3b+3b=0)
m=x-3b

________
m+3b=x

Random samples of female and male UVA undergraduates are asked to estimate the number of alcoholic drinks that each consumes on a typical weekend. The data is below:
Females (Population 1): 5, 5, 6, 6, 6, 3, 4, 6, 6, 6
Males (Population 2): 7, 3, 4, 7, 4, 7, 3, 3, 7, 4
Give a 93% confidence interval for the difference between mean female and male drink consumption. (Assume that the population variances are equal.)
Answer:
Confidence Interval =-0.76,+1.56
Step-by-step explanation:
The confidence interval can be determined by
(x1`- x2`) ± z∝/2 √s1²/n1 + s2²/n2
z∝/2 for 93% is 1.81
The mean and the standard deviations can be calculated using the calculator.
The mean x1`= ∑x/ n= 5+ 5+ 6+ 6+ 6+ 3+ 4+ 6+ 6+ 6
= 53/10= 5.3
Standard deviation = s1`= 1.0049= 1.005
The mean x2`= ∑x/ n= 7+ 3+ 4 +7+ 4+ 7+ 3+ 3+ 7+ 4/10
= 49/10= 4.9
Standard Deviation = s2= 1.75783= 1.76
Putting the values
(x1`- x2`) ± z∝/2 √s1²/n1 + s2²/n2
(5.3-4.9 ) ± 1.81 √1.005²/10 +1.76²/10
0.4 ± 1.81 √ 1.010025/10 + 3.0976/10
-0.76,+1.56
The confidence interval for 93% two tailed test is [-0.76,+1.56]
