Solve the following equation for B
y=mx+b

Answers

The answer is:
__________
b = y − mx .
__________
Explanation:
__________
Given:
__________
y = mx + b ;
_________
We want to isolate "b" on one side of the equation to solve for "b".
_______________________
→ y = mx + b ; Subtract "mx" from BOTH sides of the equation; to isolate "b" one side of the equation; and solve for "b":
____________________________________
y = mx + b → y − mx = mx + b − mx ;
____________________________________
→ y − mx = b ; ↔ b = y − mx
____________________________________
→ b = y − mx .
____________________________________

In the slope intercept form, or y = mx + b, m represents the slope, and b represents the y-intercept.

To solve for b, you just have to replace x and y in the formula with the given coordinates and replace m with the calculated value.

For example, you have to find the equation of a line with the coordinate points (1, -2) and (6, 5). Replace one set of ordered pairs in the slope intercept formula.

Graph both of the coordinate points in a coordinate plane, or a graph, to find it's slope. Use rise over run. Simply count how many points it takes to go the other ordered pair.

The slope of (1, -2) and (6, 5) is 7/5.

If you found the slope, plug those numbers in.

I used (1, -2). I plugged in the slope.
-2 = 7/5(1) + b

You just have to solve for b by simplifying the equation.

Erica went shopping for new clothes for school. She bought a pair of jeans for $70.19 and several shirts for $8.63 each. If x represents the number of shirts she bought, which of the following equations should be used to find y, the total cost of Erica's shopping trip? Explain your choice.

it's at least y=$8.63x+$70.19

Y=70.19+(8.63*X)

To find the total she spent all you have to do is add everything together. The cost of the pants was $70.19, to find how much she spent on shirts you take the amount each shirt was, which in this case is $8.63, and multiply it by how many shirts she bought. We don't know how many shirts she bought so we use the varriable of X to represent that number.

A ball on a string moves around a complete circle, once a second, on a frictionless, horizontal table. The tension in the string is measured to be 6.0N . What would the tension be if the ball went around in only half a second?

Answers

The tension in the string balances out, and thus equals the centripetal force of the ball

T = mv^2/r

if it only takes half the time to finish one orbit it has to be moving at twice the original speed.

And since v is squared T will increase by 4

T' = m(2v)^2/r

T' = 4mv^/r = 4T

T' = 24.0 N

I hope my answer has come to your help. Have a nice day ahead and may God bless you always!

Final answer:

If the ball went around in half a second, the tension in the string would be 24.0 N.

Explanation:

To find the tension in the string if the ball went around in half a second, we can use the equation for centripetal force. The tension T in the string provides the centripetal force, which is equal to the mass of the ball times the square of its velocity divided by the radius of the circle:

T = (m * v^2) / r

In this case, the mass of the ball and the radius of the circle remain the same, but the velocity changes. Since the ball takes half the time to complete the circle, the velocity is twice as fast. Therefore, the tension in the string would be four times greater:

Tension = 4 * 6.0 = 24.0 N

Jen and Heather went to lunch. When the bill came Jen discovered that she had only 8.00 dollars, luckly Heather had enough money to pay the other part or 3/5 of the bill. ...?

Answers

To answer this question, let's analyze the given problem above.
Given that Heather paid the other part of the bill which is 3/5 of the bill, then this means that, Jen paid only 2/5 of the bill. Now that Jen has only 8 dollars, this 8 dollars is equivalent to 2/5 of the bill. The next thing we are going to find out is how much did Heather pay which is 3/5 of the bill.
So 2/5 = 8 dollars
3/5 = ?dollars
Therefore, the answer would be $12. The amount that Heather paid is $12. Hope this answer helps.

The intensity I of light bulb varies inversely as the square of the distance d from the light bulb. Suppose I is 250 w/m^2 when the distance is 5 m. How much farther would it be to a point where the intensity is 40 w/m^2? ...?

Answers

Final answer:

The intensity of a light bulb varies inversely as the square of the distance from the light bulb. To find the distance where the intensity is 40 w/m², use the inverse square law formula to solve for the distance.

Explanation:

The intensity of a light bulb varies inversely as the square of the distance from the light bulb. This means that as the distance increases, the intensity decreases.

If the intensity is 250 w/m² at a distance of 5 m, and we want to find the distance where the intensity is 40 w/m², we can use the inverse square law formula:

I₁d₁² = I₂d₂²

Plugging in the values, we get:

250 × (5)² = 40 × (d₂)²

Simplifying, we find that d₂² = 250 × (5)² / 40

d₂² = 312.5

Therefore, d₂ = √312.5 ≈ 17.68

So, it would be approximately 17.68 - 5 = 12.68 meters farther to a point where the intensity is 40 w/m².

https://brainly.com/question/30562749

#SPJ12

Sure, let's solve it step by step.

First, we know that the initial intensity (I1) is 250 w/m^2 and the initial distance (d1) is 5 m. We are asked to find a distance where the intensity is 40 w/m^2, which would be our final intensity (I2).

According to the inverse square law, the intensity of light is inversely proportional to the square of the distance from the source, i.e., I ∝ 1/d². Therefore, we can say that I1 * d1² = I2 * d2². This equation allows us to find the distance at which the intensity is I2.

So, substituting the given values in the equation, we have 250 * (5)² = 40 * d2².

Now, we can solve for d2. Rearranging terms, d2 = √((250 * (5)²) / 40), which will give us d2 = 12.5 m.

So, the distance at which the intensity of light is 40 w/m^2 is 12.5 m.

However, we have been asked to find the additional distance that needs to be traveled to reach a point where the intensity is 40 w/m^2. This additional distance is the difference between the final distance (d2) and the initial distance (d1), that is, distance_travelled = d2 - d1 = 12.5 - 5 = 7.5 m.

Therefore, you would need to travel an additional 7.5 m to reach a point with an intensity of 40 w/m^2.

Chickens have 2 legs and sheep have 4 legs. If x is the number of chickens and y is the number of sheep, then we have the system of equations: x + y = 48, 2 x + 4 y = 134. We can solve this system : x = 48 - y, then we will put it into the 2nd equation: 2 * ( 48 - y ) + 4 y = 134, 96 - 2 y + 4 y = 134, 2 y = 134 - 96, 2 y = 38, y = 38 : 2, y = 19.

What value(s) of x make the equation x2 - 18x + 81 = 0 true?

Answers

1. x =(18-√648)/2=9-9√ 2 = -3.728
2. x =(18+√648)/2=9+9√ 2 = 21.728

To solve for the values of X that will make the equation true, all you have to do is factor this trinomial. Basically find 2 numbers that multiply to give you 81 and also add to give you -18, in this case the numbers would be -9 and -9. Since -9 + -9 = -18 and -9 • -9 = 81. Thus the factored expression would be like this:

(X-9)(X-9) = 0
X - 9 = 0 and X - 9 = 0
In both cases the solutions for X is that X is equal to 9.

The value of X that will make this equation true, is if X is equal to 9.

To win at LOTTO in one state, one must correctly select 6 numbers from a collection of 62 numbers (1 through 62). The order in which the selection is made does not matter. How many different selections are possible? ...?

Answers

Final answer:

The number of different selections possible when picking 6 numbers from a collection of 62 numbers for a LOTTO game is 62,891,499.

Explanation:

The question asks how many different selections are possible when picking 6 numbers from a collection of 62 numbers for a LOTTO game. Since the order of the selection does not matter, we can use the concept of combinations to solve this problem. The formula for combinations is given by C(n, r) = n! / (r! * (n-r)!), where n is the total number of items and r is the number of items selected. Plugging in the values, we have C(62, 6) = 62! / (6! * (62-6)!), which simplifies to 62! / (6! * 56!). Using a calculator or computer program to calculate the factorial, we find that C(62, 6) is equal to 62,891,499.

Final answer:

To find the number of different selections possible in a lotto where 6 numbers are chosen from 62, we use the combination formula: C(62, 6). This yields 45,057,474 possible selections.

Explanation:

Calculation of Different Selections in Lotto

To calculate the number of different selections possible when choosing 6 numbers from a set of 62 without regard to the order of selection, we use the combination formula:

The combination formula is C(n, r) = n! / (r! * (n-r)!), where C(n, r) is the number of combinations, n is the total number of items to choose from, r is the number of items to be chosen, and ! denotes factorial.

In this case, n = 62 and r = 6:

C(62, 6) = 62! / (6! * (62-6)!) = 62! / (6! * 56!)

Calculating the factorials and the division, we find that there are 45,057,474 possible selections.

Therefore, the probability of winning by correctly selecting all 6 numbers is 1 in 45,057,474, making lottery tickets a game of very low probability for individual success.

Hope this helps you

To subtract the polynomials, change the signs of the second polynomial and combine like terms. The result is -6m² + 11m - 6, which is option D.

To subtract the given polynomials, we need to subtract the second polynomial from the first one. We do this by changing the signs of the second polynomial and then combining like terms with the first.

(m² + 6m - 5) - (7m² - 5m + 1) becomes (m² + 6m - 5) + (-7m² + 5m - 1).

Now, combine the like terms:

m² - 7m² = -6m²,6m + 5m = 11m,-5 + (-1) = -6.

So, the simplified form of the polynomial after subtraction is -6m² + 11m - 6, which corresponds to option D.
