Answer: Divide by -2
Step-by-step explanation: In an equation where you have ab = n, then you divide by a. So then you get b = n/a.
If my answer was helpful, please mark it as brainliest.
Answer:
Divide by -2
Step-by-step explanation:
Since we need to isolate h, we need to do the opposite operation that -2 is doing to h. In this case, -2 is being multiplied by h, and the opposite operation to multiplication is division.
This means that we need to divide both sides by -2.
Using a directrix of y = −2 and a focus of (2, 6), what quadratic function is created?
here are the answers given
\/
f(x) = −one eighth (x − 2)2 − 2
f(x) = one sixteenth (x − 2)2 + 2
f(x) = one eighth (x − 2)2 − 2
f(x) = −one sixteenth (x + 2)2 − 2
Answer:
f(x)=1/16(x-2)^2+2
Step-by-step explanation:
The Equation can be written like this:
f(x) = 1/(4p)(x -h)^2 +(k-p)
where (h, k) is the focus, and p is half the distance between focus and directrix. Here, (h, k) = (2, 6) and p=(6-(-2))/2 = 4. So the equation is ...
f(x) = 1/16(x -2)^2 +2
HELP MEEEE Distances in space are measured in light-years. The distance from Earth to a star is 6.8 × 10^13 kilometers. What is the distance, in light-years, from Earth to the star (1 light-year = 9.46 × 10^12 kilometers)?
Answer:
≈ 7.188 LY
Step-by-step explanation:
1 LY = 9.46 * 10¹²
S = 6.8 * 10¹³
S = 6.8 * 10¹³/9.46 * 10¹² ≈ 7.188 LY

[tex]\large{\boxed{ \sf x = 1, \ x = 0 }[/tex]
Explanation:[tex]\sf \Rightarrow \dfrac{x}{x-2\:}+\:\dfrac{x-1}{x+1}=\:-1[/tex]
[tex]\sf \Rightarrow \dfrac{x(x+1)+(x-1)(x-2)}{(x-2)(x+1)}=\:-1[/tex]
[tex]\sf \Rightarrow \dfrac{x^2+x+x^2-2x-x + 2}{x^2 - 2x + x - 2}=\:-1[/tex]
[tex]\sf \Rightarrow 2x^2-2x+ 2=\:-1(x^2 - 2x + x - 2)[/tex]
[tex]\sf \Rightarrow 2x^2-2x+ 2=\:-x^2 + 2x - x + 2[/tex]
[tex]\sf \Rightarrow 2x^2+x^2 -2x - x+ 2-2=0[/tex]
[tex]\sf \Rightarrow 3x^2 - 3x = 0[/tex]
[tex]\sf \Rightarrow 3x(x - 1) = 0[/tex]
[tex]\sf \Rightarrow 3x = 0 , \ x - 1 = 0[/tex]
[tex]\sf \Rightarrow x = 0 , \ x =1[/tex]
Answer:
x = 0 or x = 1
Step-by-step explanation:
Given equation:
[tex]\dfrac{x}{x-2}+\dfrac{x-1}{x+1}=-1[/tex]
Multiply the two denominators to get the same denominator:
Multiply the numerator of the first fraction by the denominator of the second fraction to get the new numerator of the first fraction.
Multiply the numerator of the second fraction by the denominator of the first fraction to get the new numerator of the second fraction.
[tex]\implies \dfrac{x(x+1)}{(x-2)(x+1)}+\dfrac{(x-2)(x-1)}{(x-2)(x+1)}=-1[/tex]
Add the numerators and keep the denominator so that there is now one fraction:
[tex]\implies \dfrac{x(x+1)+(x-2)(x-1)}{(x-2)(x+1)}=-1[/tex]
Simplify the numerator by expanding the brackets:
[tex]\implies \dfrac{x^2+x+x^2-3x+2}{(x-2)(x+1)}=-1[/tex]
[tex]\implies \dfrac{2x^2-2x+2}{(x-2)(x+1)}=-1[/tex]
Simplify the denominator by expanding the brackets:
[tex]\implies \dfrac{2x^2-2x+2}{x^2-x-2}=-1[/tex]
Multiply both sides by the denominator of the left side:
[tex]\implies 2x^2-2x+2=-1(x^2-x-2)[/tex]
Simplify and move everything to the left side:
[tex]\implies 2x^2-2x+2=-x^2+x+2[/tex]
[tex]\implies 3x^2-3x=0[/tex]
Factor:
[tex]\implies 3x(x-1)=0[/tex]
Therefore:
[tex]\implies 3x=0 \implies x=0[/tex]
[tex]\implies x-1=0 \implies x=1[/tex]
Therefore, x = 0 or x = 1

Lou's shoe was 9.178 inches long, Helen's shoe was 7.093 inches long, Jay's shoe was 10.554 inches long and Craig's shoe was 4.112 longer than Helen's. How long will the row of shoes be if someone placed them in a line from end to end?
Answer:
38.03 in
Step-by-step explanation:
Step 1: Calculate Craig's shoe length.
It's 4.112 in longer than Helen's shoe, which is 7.093 in. So, we simply add those two numbers to get 11.205.
Step 2: Add up all of the numbers
Now that we have everyone's shoe lengths, we just add them all up to get 38.03 in.

The number of pages that Ana, Hillary, Roger, and Juan can read in a day is shown below:
Ana read 15% of her 46-page book.
Hillary read 11% of her 72-page book.
Roger read 12% of his 68-page book.
Juan read 14% of his 69-page book.
Who can read the greatest number of pages in a day?
Ana
Hillary
Roger
Juan
Answer: Juan
Step-by-step explanation:
Step 1: Find how many pages each person read.
ANA
15% of her 46 page book
Whenever you have something% OF something, you just turn the 'of' into a multiplication sign.
15% x 46
Next, turn 15% into a decimal. There are 3 ways to do this. (1. put a decimal point right before the number (2. move it 2 places to the right, (3. just divide by 100. Either way, 15% becomes 0.15
0.15x46= 6.9
Ana can read 6.9 pages in a day.
HILARY
11% of a 72 page book
Same method I used for Ana. turn "of" into multiplication, convert the percentage to a fraction by moving the point 2 places left, and multiply.
**11 is the same as 11.0, which becomes 0.11.**
11% x 72
0.11x72= 7.92
Hilary can read 7.92 pages in a day.
ROGER
12% of 68 pages
of becomes multiply
12% becomes 0.12 because 12 is the same as 12.0, and you move 12 2 places to the left.
now we have 0.12x68= 8.16
JUAN
14% of 69 pages
of becomes multiply, 14 is the same as 14.0, move it 2 places to the left and it becomes 0.14. boom.
0.14x69= 9.66
Juan can read 9.66 pages in a day.
Step 2: Line up all of the numbers and find the biggest one.
Ana: 6.9 pages per day
Hilary: 7.92 pages per day
Roger: 8.16 pages per day
Juan: 9.66 pages per day
9.66 is the greatest number.
Juan can read the most pages per day

Answer:
the second option from the top is correct. (the one with the dot on -4)
Step-by-step explanation:
d/-2 + 5 = 7
d/-2 = 7 - 5
d/-2 = 2
d = 2 * -2
d = -4
Answer:
Option 2, d = -4
Step-by-step explanation:
d/-2 + 5 = 7 (subtract 5 from both sides)
d/-2 = 2 (multiply by -2 to both sides)
d = -4

Yes, because the quotient of Fraction 1 and 3 over 4 ÷ fraction 2 over 3 is 2 and 5 over 8
No, because the quotient of Fraction 2 over 3 ÷ Fraction 1 and 3 over 4 is 1 and 2 over 12
No, because the quotient of Fraction 1 and 3 over 4 ÷ fraction 2 over 3 is 1 and 2 over 12

The surface areas of the solids shown above are equal, but their lateral
surface areas are not.
A. True
B. False
Answer:
Flase
Step-by-step explanation:
Solid a has a surface area of 170 sq ft.
Solid b has a surface area of 126 sq ft.
Just knowing this information we already know that the statement is false
Answer:
False
Step-by-step explanation:
1. Find the surface area
Shape 1 Shape 2
(4 x 5)2 + (5x5)4 = 140 (6 x 3)2 + (3 x 5)2 + (6 x 5)2 = 126
2. Exclude the bases
Shape 1 Shape 2
140 - 40 = 100 126 - 36 = 90
All in all, this is FALSE
