the equation is exactly the same on both sides but just expressed differently
Edge: Which equation has a focus at (–6, 12) and directrix of x = –12?
The solution is, b. x² = 12(y + 3) equation represents a parabola that has a focus of (0, 0) and a directrix of y = −6
What is parabola?The parabola is a plane curve which is mirror symmetrical and is approximately U-shaped. It fits several superficial different mathematical descriptions.
here, we have,
If the focus is (0,0) and the directrix is y=-6, the equation will be found as follows:
Let (x,y) be any point on the parabola. Find the distance between (x,y) and the directrix, then find the distance between (x,y) and the focus. Equate these two distance equations and the simplified equation in x and y is equation of the parabola.
The distance between (x,y) and (0,0) is √(x²+y²)
The distance between (x,y) and the directrix, y=-6 is ly+6l
Equate the two distance expressions and square on both sides
√(x²+y²)=ly+6l
x²+y²=(y+6)²
simplifying and bringing terms together we get:
x²-12y-36=0
make x² the subject:
x²=12y+36
x²=12(y+3)
Hence, Answer :b. x² = 12(y + 3)

The price of a washing machine was decreased by 20% to £640.
What was the price before the decrease?
Answer:
£800
Step-by-step explanation:
Use the percentage formula: NV = m x OV
NV is New Value;
m is Multiplier;
and OV is Old Value.
£640 in the New value, so now we have to convert 20% to a multiplier and find out the Old value.
Make OV the subject of the formula: OV = NV / m
So 20% decrease would mean: 100 - 20 = 80 * 100 = 0.80
Divide 640 (NV) by 0.80 (m) and it will give you:
£800
And it would make sense that the OV is higher, and it matches the statement -> as the NV is the decrease.

Answer:
1/10 or 10%Step-by-step explanation:
Probability = favorable outcome / total number of outcomes
p(5) = 1/65 numbers left and 3 of them are even.
p(even) = 3/5So combined probability is:
p(5 and even) = 1/6*3/5 = 1/10Find the value of x, y, and z
Answer:
Step-by-step explanation:
x + 28 + 39 = 180
x + 67 = 180
x = 113
y + 113= 180
y = 67
z + 67 + 64 = 180
z + 131 = 180
z = 49
Mercury is the closest planet to the sun at a distance of 36 million miles. The closest star to the sun is Proxima Centauri, which is 4.24 light years away. A light year is 5.9 x 10 to the 12th power. How many miles from the sun is Proxima Centauri?
Answer:
2.36 * 10^13 miles
Step-by-step explanation:
Given that :
Proxima centauri is at a distance of 4.24 light years away from the sun.
Distance in miles of Proxima centauri from the sun ;
1 light year = 5.9 * 10^12 miles
Number of light years from the sun * 5.9 * 10^12
= 4 * (5.9 * 10^12)
= 23.6 * 10^12 miles
= 2.36 * 10^13 miles
