Consider the equation:
X^2-6 = 2 – 18x
1) Rewrite the equation by completing the square
2) What are the solutions to the equation?
The equation should be rewritten by completing the square as x² + 18x + (18/2)² = 8 + (18/2)².
The solutions to the equation is x = -9 + √89 or x = -9 - √89.
What is a quadratic equation?In Mathematics and Geometry, the standard form of a quadratic equation is represented by the following equation;
ax² + bx + c = 0
Next, we would solve the given quadratic equation by using the completing the square method;
x² - 6 = 2 - 18x
x² + 18x = 8
In order to complete the square, we would have to add (half the coefficient of the x-term)² to both sides of the quadratic equation as follows:
x² + 18x + (18/2)² = 8 + (18/2)²
x² + 18x + 81 = 8 + 81
Part 2.
x² + 18x + 81 = 89
x² + 9x + 9x + 81 = 89
x(x + 9) + 9(x + 9) = 89
(x + 9)(x + 9) = 89
x = -9 + √89 or x = -9 - √89.

Jay organised a large wedding and 1/3 of them chose beef 5/12 of them chose Chicken and 69 of them chose vegetarian so how many guest were at the wedding ?
Answer:
276 Guests
Step-by-step explanation:
Calculation to determine how many guest were at the wedding
Guests that choose beef =1/3
Guests that choose chicken= 5/12
Guests that choose vegetarian=69
Now let calculate the how many guest were at the wedding
Let x represent the numbers of guest that were present at the wedding
Hence,
x/3 + 5x/12 + 69 = x
9x/12 + 69 = x
12x/12 - 9x/12 = 69
3x/12 = 69
x/4 = 69
x=69*4
x = 276 guests
Therefore the numbers of guests that were at the wedding is 276
Answer: 276
Step-by-step explanation: Let “x” be the number of guest.
1/3 x +5/12x + 69 = x Simplifying and solving for x … where x = 276
1/3(276) + 5/12(276) + 69 = 276
92 + 115 + 69 = 276
solve the linear system
Eq 1: 2x -4y = -2, Eq 2: 3x + y =4
Answer:
(1, 1 )
Step-by-step explanation:
Given the 2 equations
2x - 4y = - 2 → (1)
3x + y = 4 → (2)
Multiplying (2) by 4 and adding the result to (1) will eliminate the y- term
12x + 4y = 16 → (3)
Add (1) and (3) term by term to eliminate y
14x + 0 = 14
14x = 14 ( divide both sides by 14 )
x = 1
Substitute x = 1 into either of the 2 equations and solve for y
Substituting into (2)
3(1) + y = 4
3 + y = 4 ( subtract 3 from both sides )
y = 1
solution is (1, 1 )

Anita has a cellphone contract that costs her R100 per month plus 85 cents per peak time SMS,and 25 cents per off-peak time SMS.if she sends 45 SMSs during peak time and 105 SMSs during off-peak time In a month, what will her monthly bill come to?
Answer:
Anita's monthly bill will be $164.25.
Step-by-step explanation:
Since Anita has a cellphone contract that costs her R100 per month plus 85 cents per peak time SMS, and 25 cents per off-peak time SMS, if she sends 45 SMSs during peak time and 105 SMSs during off-peak time In a month To determine what will her monthly bill come to, the following calculation must be performed:
100 + (0.85 x 45) + (0.25 x 105) = X
100 + 38.25 + 26.25 = X
138.25 + 26.25 = X
164.25 = X
Therefore, her monthly bill will be $ 164.25.

Answer:
x=2, y = -4.
or as an ordered pair it is (2, -4).
Step-by-step explanation:
-x + 6y = -26
x + 5y = -18 Add these 2 equations to eliminate x:
0 + 11y = -44
y = -44/11 = -4.
Now substitute y = -4 in the first equation:
-x + 6(-4) = -26
-x - 24 = -26
-x = -26 + 24 = -2
x = 2.
Check the result by substituting in equation 2:
x + 5y = 2 + 5(-4) = 2 - 20 = -18 - checks out.
Use the distance formula to find the distance to the nearest tenth, from R17, -2) to W(-2, 3).
Answer:
17.7
Step-by-step explanation:
I'm assuming you meant R(17, -2) to W(-2, 3). Here the x-coordinate changes by 17 - (-2), or 19, and the y-coordinate by 5. Think of these as the legs of a right triangle. The distance between these points is the length of the hypotenuse of this triangle: d = √(5^2 + 17^2)
or √314, which, to the nearest tenth is 17.7.

Answer: y=5/3x-4
Step-by-step explanation:
Hi, you could find the slope with any 2 points on the line. For accuracy, I will choose the points (6, 6) and (0, -4), meaning when x =6, y=6, and when x=0, y=-4. Then you can set up an equation. Because the line on this graph is linear (meaning straight), the form of the equation would be y=ax+b. (If it was a parabola, it would be y=ax^2+bx+c).
y=mx+b (Or some people prefer y=ax+b, but the same thing).
Now, plug in the x and y values, getting:
6 = 6m+b and -4=0*m+b
When you simplify, you will get that b is -4, and then m is 5/3
So the equation is y=5/3x-4
You can plug the numbers of x and y in to check your answer.
Hope this helps!
