7.5d = 2.5d Lin divided each side by 2.5d and Elena subtracted 2.5d from each side with both leads to the solution

Answers

Answer:

Elena's move will lead to the solution of the problem

Step-by-step explanation:

To solve the equation 7.5d=2.5d, Lin divides each side by 2.5d, and Elena subtracts 2.5d from each side. Will both moves lead to the solution? Explain your reasoning

Given:

7.5d = 2.5d

Lin divides each side by 2.5d, Lin:

7.5d / 2.5d = 2.5d / 2.5d

3 = 1

This can not be the solution to the problem because 3 can not be Equal to 1

Elena subtracts 2.5d from each side

7.5d = 2.5d

7.5d - 2.5d = 2.5d - 2.5d

5d = 0

This can lead to the solution of the problem

Elena's move will lead to the solution of the problem

How do you get the fully simplified slope-intercept form?​

Answers

Answer:

y = 3x - 7

Step-by-step explanation:

Slope-intercept form:

y = mx + b

Where:

y is the y value.

m is the slope.

x is the x value.

And b is the y-intercept.

First, you want to find your slope. To do this, you can either use the slope formula to find the slope, or just count on the picture:

m = rise/run

m = 3/1

m = 3

With the slope formula, you first need to choose two points.

I chose:

(2, -1) and (3, 2)

Slope formula:

m = (y2 - y1) / (x2 - x1) {It doesn't matter which point you choose to be x2 and x1, just be consistent when you plug it into the formula}

m = (2 - (-1)) / (3 - 2)

m = 3/1

m = 3

Now that you have your slope, all you need is your y-intercept. To find your y-intercept, you can either look at the graph (again) to see where the line intersects with the y-axis, or you can solve it algebraically:

y-int = -7

To solve algebraically, choose a random point on the line and plug it into what you have for your equation so far and then solve for b.

I chose:

(2, -1)

y = 3x + b

-1 = 3(2) + b

-1 = 6 + b

-1 - 6 = b

b = -7

Now you have your final answer:

y = 3x - 7

What is equation of a line?

The equation of a line is a form of representing the set of points, which form a line in a coordinate system. 

The general equation of a straight line is given as:

y = mx + c,

where m = slope of the line and c = y-intercept.

We have,

y = mx + b _____(1)

y - y1 = m(x - 1) _____(2)

Ax + By = 0 _____(3)

y=kx ______(4)

From all the equations given above, we see that,

Equation (1) is in the form of a point-slope.

Thus,

The point-slope form of a linear equation is represented by y = mx + b.

Option A is the correct answer.

Answers

The possible amount of money in the other piggy bank correct is x < 2.69.

Given that,

Teddy has two piggy banks.

And, The difference in the amount of money between the two banks is no more than $10.

Here, One piggy bank has $7.31 in it.

Let us assume that,

The amount of money in the other piggy bank  = x

Hence, the inequality is,

7.31 + x < 10

Solve for x,

x < 10 - 7.31

x < 2.69

Therefore, x < 2.69 is the possible amount of money in the other piggy bank.

Step-by-step explanation:

Given

5x³ - 2x² + 5x - 2 = 0 ( factor the first/second and third/fourth terms )

x²(5x - 2) + 1(5x - 2) = 0 ← factor out (x - 2) from each term

(5x - 2)(x² + 1) = 0

Equate each factor to zero and solve for x

Casey wants to buy a gym membership. One gym has a $248 joining fee and costs $27 per month. Another gym has no joining fee and costs $58 per month. In how many months will both gym memberships cost the same? What will that cost be?

Answers

Answer:

In 8 months both gym memberships will cost the same and that cost will be $464

Step-by-step explanation:

Linear Models

To compare two gym memberships, we can help Casey to form one model for each gym.

One of them charges a $248 joining fee plus $27 per month. The model for this gym is:

G1 = 27m + 248

Where m is the number of months.

The other gym has no joining fee but charges $58 per month. It's model is:

G2 = 58m

The number of months where both gyms end up charging the same can be found by equating G1 = G2, or equivalently:

27m + 248 = 58m

Subtracting 27m and swapping the equation:

58m - 27m = 248

Simplifying:

31m = 248

Solving:

m = 248/31

m = 8

When m=8, both gyms charge the same:

G1 =27*8 + 248= $464

G2 = 58*8 = $464

Thus, in 8 months both gym memberships will cost the same and that cost will be $464

express cos6mcos2m as a sum or difference

Answers

Given :

An expression (cos 6m)(cos 2m) .

To Find :

We need to express it in terms as sum or difference.

Solution :

We know,

cos( A + B ) = cosA cos B - sin A sin B

cos( A - B ) = cosA cos B + sin A sin B

Adding both the equations we get :

2cos A cos B = cos( A + B) + cos( A - B )

or

cos A cos B = cos( A + B) + cos( A - B )/2

Putting value of A = 6m and B = 2m in above equation, we get :

(cos 6m)(cos 2m) = cos( 6m + 2m ) + cos( 6m - 2m )/2

(cos 6m)(cos 2m) = cos(8m) + cos(4m)/2

Hence, this is the required solution.
