The value of y varies directly with x and y= 125 when x = 25. what is the value of y when x=2?
Answer:
Y = 10
Step-by-step explanation:
As, Y / X = 125/25
125/25 = 5
Therefore, y = 5x
So when x = 2
Y = 5x
So, Y = 5x2
Therefore, Y = 10
[y] will be equivalent to 10, if [x] is equal to 2
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
y = mx also represents direct proportionality. We can write [m] as -
m = y/x
OR
y₁/x₁ = y₂/x₂
Given is the value of [y] varies directly with [x] and y = 125 when x = 25.
Using the formula for direct proportionality -
y₁/x₁ = y₂/x₂
125/25 = y₂/2
y₂ = (125 x 2)/25
y₂ = 5 x 2
y₂ = 10
Therefore, [y] will be equivalent to 10, if [x] is equal to 2

Earth is represented on a map of a portion of the solar system so that its surface is the circle with equation x2+y2+8x+2y−4883=0. A weather satellite circles 0.4 unit above Earth with the center of its circular orbit at the center of Earth. Find the general form of the equation for the orbit of the satellite on this map.
Answer:
The general form of the equation for the orbit of the satellite is [tex]x^{2}+y^{2}+8\cdot x+2\cdot y = 4939.16[/tex].
Step-by-step explanation:
From statement we have the general equation of the elliptic form of Earth. First we have to transform this formula to the standard form of the equation of the circle. That is:
1) [tex]x^{2}+y^{2}+8\cdot x +2\cdot y -4883=0[/tex] Given
2) [tex](x^{2}+8\cdot x)+(y^{2}+2\cdot y) = 4883[/tex] Associative, commutative and modulative properties/Compatibility with addition/Existence of additive inverse.
3) [tex](x^{2}+8\cdot x +16)+(y^{2}+2\cdot y+1)-17=4883[/tex] Associative, commutative and modulative properties/Compatibility with addition/Existence of additive inverse.
4) [tex](x+4)^{2}+(y+1)^{2} = 4900[/tex] Square perfect trinomial/Result
According the result, the center of Earth is [tex]C(x,y) = (4, 1)[/tex] and the square of the radius of Earth equals 4900. That is: [tex]r = 70[/tex]
If satellite circles 0.4 unit above Earth, then the equation of the orbit of the satellite is:
[tex](x+4)^{2}+(y+1)^{2}=70.4^{2}[/tex]
[tex](x+4)^{2}+(y+1)^{2} = 4956.16[/tex]
Now we transform this into its general form:
1) [tex](x+4)^{2}+(y+1)^{2} = 4956.16[/tex] Given
2) [tex]x^{2}+8\cdot x +16+y^{2}+2\cdot y+1 = 4956.16[/tex] Square perfect trinomial
3) [tex]x^{2}+y^{2}+8\cdot x+2\cdot y = 4939.16[/tex] Associative, commutative and modulative properties/Compatibility with addition/Existence of additive inverse/Result
The general form of the equation for the orbit of the satellite is [tex]x^{2}+y^{2}+8\cdot x+2\cdot y = 4939.16[/tex].

What is the m< BAD? ( If you are confused look at the picture provided)
Answer:
The measurement of angle BAD would be 120°.
How To Do It:
You set the expressions equal to each other & solve for x. Then you plug x into each expression & add them.
Set Expressions Equal To Each Other To Find The Value Of X:
(13x-31)=(x+53)----------add 31 to each side
13x=(x+84)----------subtract x from both sides
12x=84----------divide both sides by 12
x=7
Plug-In The Value Of X To Each Expression & Add:
(13(7)-31)+((7)+53)----------distribute the 7 to each coefficient
(91-31)+(7+53)----------add/subtract numbers inside the parentheses
(60)+(60)----------add the final products together
120----------*Final Answer*

what is 2x+54+4x-6=180
Answer:
=22
Step-by-step explanation:
Subtract the numbers
2+54+4−6=180
2+48+4=180
Combine like terms
2+48+4=180
6+48=180
Subtract 48 from both sides of the equation
6+48=180
6+48−48=180−48
Simplify
Subtract the numbers
Subtract the numbers again
6=132
Divide both sides of the equation by the same term
6=132
6/6=132/6
Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
=22

A market buys mixed nuts at $12.50 per pound. They want to make a 22% profit. What should they charge for retail price? Please help I’m begging!
Answer:
the answer is 15.25/lbs
Step-by-step explanation:
you just plug in 1.22 (12.50) pls vote if my answer was right
Answer:
$15.25
Step-by-step explanation:
Divide 12.50 by 100 to get 0.125
Multiply 0.125 times 122 to get 15.25
You divide by 100 to get 1% of what $12.50 is, then multiply that by 122 to get $12.50 + a 22% profit.
Finally, just add your units to get the answer of $15.25 per pound.

Mrs. Wright sold t-shirts for $12.00, which was a 30% markup from what she paid for each. How much did Mrs. Wright pay for each t-shirt originally? (remember to round to the nearest hundredth so it looks like money
Answer:
She originally paid $3.60
Step-by-step explanation:
She originally paid for them $3.60 before the markup of 30%.
We can use this equation [tex]12 x 0.3 = 3.60[/tex] to confirm our answer. We also add a zero at the end because we are using units of money.

What is the greatest common factor?The largest number among all the common factors of the given numbers is known as the GCF (Greatest Common Factor) of two or more numbers. The greatest integer that may be used to divide two natural numbers x and y without producing any remainders is called their GCF.
The greatest common factor is the largest positive number which can be divided into given numbers evenly.
Given that you are filling picnic baskets. You have 18 sandwiches, 24 granola bars, and 42 apples.
The greatest common factor between the numbers 42, 18, and 24 will be 6.
42 / 6 = 7
18 / 6 = 3
24 / 6 = 4
Therefore, the greatest number of baskets will be 6.

Find the solution set for this inequality:
-4(3x-5)<2(3x+4)
Answer: x> 2/3
Step-by-step explanation:
Answer:
x > 2/3 OR (2/3, ∞ )
What’s the answer
Apparently didn’t paid attention in class
This equation can be written as :-
= 6 + 4x = x + 15
= 4x+6=x+15
= 4x + 6 − x = x + 15 − x
= 3x + 6 = 15
= 3x + 6 − 6 = 15 − 6
= 3x = 9
= 3 x 3 = 9
= x = 9 ÷ 3
= x = 3
Using this , let us solve the equation :-
= 6 + 4 × 3 = 3 + 15
= 6 + 12 = 3 + 15
= 18 = 18
Therefore , 6 + 4x = x + 15 = 18 ( x = 3 ) .

V /(lw) = h
V /(lw) = h
V = lwh
Divide each side by lw
V/ ( lw) = lwh/(lw)

How many times farther from the Sun is Neptune than Mercury?
How long does it take light to reach neptune?
80 times farther from the Sun is Neptune than Mercury.
Given that, the distance between Mercury and Sun = 35,000,000 miles and the distance between Neptune and Sun = [tex]2.8\times10^9[/tex].
What is an average distance?An average distance is the average of the greatest and least distances of a celestial body from its primary.
Now, number of times farther from the Sun is Neptune than Mercury
= [tex]\frac{2.8\times10^9}{3.5\times10^7}[/tex]
