Consider solving 푥2+12푥+5=0by completing the square. What number should be added to both sides of the equation? 푥2+12푥+_____=−5+_____a. -36b. 36c. 16d. -16
Answer:
B. 36
Step-by-step explanation:
The equation in question is not well written. Let the equation be;
x²+12x+5 = 0
In order to know what number should be added to both sides of the equation, we will take the square of the half of coefficient of x as shown;
Coefficient of x = 12
Half of 12 = 1/2(12) = 6
Square of 6 = 6² = 36
Hence the required number to add to both sides of the equation by completing the square method is 36

what eqwation of a parabola with a focus(6,-2) and a directrix x=-2
Answer:
The equation of the parabola
( y +2 )² = 16 (x-2)
Step-by-step explanation:
Step(i):-
Given the focus of the Parabola ( 6, -2 )
we know that the Focus of the Parabola
( h + a , k ) = ( 6 , -2 )
Comparing
h + a = 6 ...(i)
and k = -2
Given directrix of the parabola
x = -2
The directrix of the parabola x = h - a = -2
h - a = -2 ...(ii)
Adding (i) and (ii) equations , we get
h + a + h-a = 6 -2
2 h = 4
⇒ h = 2
Substitute 'h' = 2 in equation (i) , we get
h + a = 6
2 + a = 6
a = 6 -2 =4
Step(ii):-
The equation of the parabola having Vertex ( h,k) = (2 , -2) and a = 4
[tex](y-k)^{2} = 4a ( x-h)[/tex]
( y - (-2))² = 4 (4) ( x -2)
Final answer:-
The equation of the parabola
[tex](y-(-2))^{2} = 4(4) ( x-2)[/tex]
( y +2 )² = 16 (x-2)

Avery has a points card for a movie theater. She receives 75 rewards points just for signing up. She earns 6.5 points for each visit to the movie theater. She needs 140 points for a free movie ticket. How many visits must Avery make to earn a free movie ticket?
Answer:
10 times
Step-by-step explanation:
After signing up she received 75 points, so the number of points he needs to get a free ticket : 140 - 75 = 65
If she earns 6.5 points or each visit, she would have to visit 65/6.5 times to get a free ticket
65/6.5 = 10

Answer:
Step-by-step explanation:
Function rule:
y = 10(0.95)ˣ
If a function is given as,
y = a(b)ˣ
a represents 'Initial value'
b represents the growth factor
If 0 < b < 1, function is a decay function.
If b > 1, function is a growth function.
For 2 = 10(0.95)ˣ,
Here, b = 0.95 which is in the interval of 0 < 0.95 < 1
So it's a decay function.
[tex]\frac{2}{10}=(0.95)^x[/tex]
log(0.2) = log[(0.95)ˣ]
log(0.2) = x[log(0.95)]
-0.6989 = -x(0.0223)
x = 31.44
x ≈ 31
Meaning → For 'x' = 31, value of the function is 2.
For 8 = 10(0.95)ˣ,
0.8 = (0.95)ˣ
log(0.8) = log(0.95ˣ)
log(0.8) = xlog(0.95)
x = 4.35 ≈ 4.4
Means, at x = 4.4, value of the function was 8.

Step-by-step explanation:
robert gets a loan from his bank.
he agrees to borrow £6000 at a fixed annual simple interest rate of 7%.
he also agrees to pay the loan back over a 10 year period.
how much money in total will he have paid back at the end of 10 years?
Answer:
the total amount that should be paid back at the end of 10 years is £10,200
Step-by-step explanation:
The total amount that should be paid back at the end of 10 years is shown below:
= Borrowed amount + simple interest
= £6000 + (£6000 × 0.07 × 10)
= £6000 + £4,200
= £10,200
Hence, the total amount that should be paid back at the end of 10 years is £10,200

Answer:
B ($905)
Step-by-step explanation:
Plug in $17 for the h value in the equation, and you get this:
c = 50 (17) + 55
c = 850 + 55
c = 905
So the answer is $905 for 17 hours of work (plus the service fee)

Which property best describes the congruence statement below?
ДАВС = ДАВС
A. Symmetric property
OB. Reflexive property
OC. Commutative property
O O O
D. Transitive property
Answer:
I think B.Reflexive property
The property best describes the congruence statement is
Symmetric property.
What is Congruence?Congruent means same shape and same size. So congruent has to do with comparing two figures, and equivalent means two expressions are equal. So to say two line segments are congruent relates to the measures of the two lines are equal.
We know,
The Symmetric Property states that for all real numbers
if x = y then y=x
and, Transitive Property
The Transitive Property states that for all real numbers
if x = y and y = z then z=x.
and, Reflexive Property
for any x, x = x.
Here, the property used is Symmetric.

An ounce of almonds costs $1.40. If Joey buys 2.4 ounces of almonds, how much will he have to pay?
Answer:
Joey will pay $3.36 for 2.4 ounces of almonds.
Step-by-step explanation:
Given that:
Cost of almonds = $1.40 per ounces
Number of ounces bought by Joey = 2.4 ounces
Cost of 2.4 ounces = Ounces of almond * Cost per ounce of almond
Cost of 2.4 ounces = 2.4 * 1.40
Cost of 2.4 ounces = $3.36
Hence,
Joey will pay $3.36 for 2.4 ounces of almonds.
Refer to the diagram shown.

Find the slope of this Linear Function.
Answer:
The slope is 2/3 and the y intercept is -1
Step-by-step explanation:
you find the y-intercept (where the line passes through the y-axis) which is -1 and you go straight up 2 spots and then you go over 3 spots. Slope is rise over run. You could also use the slope formula y2-y1/x2-x1. I hope this made sense.
