What is the equation of the line that is perpendicular to the given line and passes through the point (3, 0)? 3x + 5y = −9 3x + 5y = 9 5x − 3y = −15 5x − 3y = 15
Answers
Answer:
5x - 3y = 15
Step-by-step explanation:
3x + 5y = −9 can be solved for y (and thus for the slope explicitly):
5y = -3x - 9, or y = (-3/5)x - 9/5. The slope of the given line is -3/5. The slope of a line perpendicular to the given line is the negative reciprocal of this -3/5, which is 5/3. Substituting 3 for x and 0 for y, our slope-intercept equation y = mx + b becomes 0 = (5/3)(3) + b, which leads to b = -5:
y = (5/3)x - 5. We must put this back into standard form, starting by multiplying all three terms by 3:
3y = 5x - 15, or -5x + 3y = -15. This is equivalent to 5x - 3y = 15 (which is the last answer choice).

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
Answers
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

Final Answer:
\(1\frac{13}{20}\)
--------------------------------------------------------------------------------------------------------------
*Please mark brainliest if that helped!*
Answer:
1 \(\frac{13}{20}\)
Step-by-step explanation:
1. Convert both \(\frac{1}{4}\) and \(\frac{3}{5}\) into a common denominator. 4 multiplied by 5 is 20. 20 works for both 4 and five. So convert the denominator into 20. Multiply \(\frac{1}{4}\) by \(\frac{5}{5}\) and multiply \(\frac{3}{5}\) by \(\frac{4}{4}\)
2. You should've gotten, \(\frac{5}{20}\) and \(\frac{12}{20}\)
3. 6 - 4 = 2, so 2 \(\frac{5}{20}\) - \(\frac{12}{20}\)
4. You have to convert 1 into \(\frac{20}{20}\) and add that to \(\frac{5}{20}\). You should've got \(\frac{25}{20}\)
5. Subtract.
The Answer is 1 \(\frac{13}{20}\)

What evidence supports a conservation law?
Carbon dioxide becomes glucose and oxygen during photosynthesis.
Hydrogen is made from the breakdown of carbon dioxide during photosynthesis.
Chlorophyll converts sunlight to chemical energy during photosynthesis.
Glucose and oxygen become carbon dioxide and water during photosynthesis.
Answers
Answer:
Chlorophyll converts sunlight to chemical energy during photosynthesis.
Step-by-step explanation:
Three forms of energy come into play in the functioning of an ecosystem:
* the electromagnetic radiation of short-wavelength (light),
* the electromagnetic radiation of long-wavelength (infrared: heat),
* chemical energy (in the form of organic molecules: sugars, etc.).
The conversion of light energy into chemical energy takes place in plants: it's photosynthesis.
Answer:
Carbon dioxide react with water and becomes glucose and oxygen during photosynthesis.
Step-by-step explanation:
6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, form glucose and oxygen.( during photosynthesis carbon dioxide and H2O in presence of sunlight and chlorophyll form glucose and oxygen)

to solve how much ice there is you need to do 16 • .30, which would get you 4.8
Now you need to subtract 4.8 from 16, since the 4.8 is the amount of ice in the glass of juice.

What is the equation of the line that passes through the point (-2,7) and is perpendicular to the line x-4y = 24?
Answers
step by step—
Answer:y = -4x - 1
Step-by-step explanation:
x - 4y = 24
-4y = -x + 24
y = x - 6
m⊥ = -4
y = -4x + b
7 = -4 ( -2 ) + b
7 = 8 + b
b = -1
y = -4x - 1

what value of x makes this equation true -(x+3)=2(x-3)
A. 0
B. 1
C. 2
D. 3
Answers
Answer:
To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:
Step 1: Distribute the negative sign on the left side of the equation:
-(x + 3) = 2(x - 3)
=> -x - 3 = 2(x - 3) (using the distributive property)
Step 2: Expand the right side of the equation:
-x - 3 = 2x - 6
Step 3: Add x to both sides of the equation to isolate the x term on one side:
-x + x - 3 = 2x + x - 6
=> -3 = 3x - 6
Step 4: Add 6 to both sides of the equation:
-3 + 6 = 3x - 6 + 6
=> 3 = 3x
Step 5: Divide both sides of the equation by 3 to solve for x:
3/3 = 3x/3
=> 1 = x
So, the correct value of x that makes the equation true is B. 1.
PLEASE MARK BRAILYISTT :D
Answer:
B, one
Step-by-step explanation:
In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.

How to use a pattern to find the product of a decimal
Answers
Answer:
A decimal sequence is a set of decimals that follow each other in order, and we use a rule, or pattern, to go from one number to the next. To find the rule for a sequence, we take two consecutive numbers and subtract them.
Answer:
Step-by-step explanation:
So I don't know if this will help or is the answer that you're looking for but here:
If you're multiplying a decimal by 1, it obviously stays the same.
ex: 1 x 0.25 = 0.25
If you multiply by 10 then you move the decimal place once to the right, as it gets bigger
ex: 10 x 0.25 = 2.5
you can do this for any number:
10 x 3.44 = 34.4
you can also use any power of 10.
10^2/100
100 x 2.75 = 275/275.0
