Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

  (a)  -2

  (b)  y -120 = -2(x -10)

  (c)  y = -2x +140

  (d) 2x +y = 140

Step-by-step explanation:

Given a graph with y-intercept 140 and x-intercept 70, you want the slope and various equations describing the graph.

The line drops from a y-value of 140 to 0 as x increases from 0 to 70. The slope is ...

  m = rise/run = -140/70 = -2

The slope of the line is -2.

The point-slope equation of the line with slope m through point (h, k) is ...

  y -k = m(x -h)

We have a line with slope -2 that goes through the point (10, 120), so we can write the equation as ...

  y -120 = -2(x -10)

In part (a) we identified the y-intercept as 140, so we can write the equation as ...

  y = mx + b . . . . . line with slope m and y-intercept b

  y = -2x +140 . . . . . . line with slope -2 and y-intercept 140

The slope-intercept equation can be converted to standard form by adding the opposite of the x-term to both sides.

  y +2x = -2x +2x +140 . . . . . 2x added to both sides

  2x +y = 140 . . . . . . . . . standard form equation of the line

The equation that represents the graph that gives the number of servings, y, in x pints of frozen yogurt is: y = 3x.

A proportional relationship graph is a straight line graph that passes through the point of origin, (0, 0), which has an equation that can be expressed in the slope-intercept form as y = kx.

"k" is the constant of proportionality, which is the ratio of y to x. k = y/x.

Given the graph above, we need to find the constant of proportionality, k. To do this, use the coordinates of one point on the graph, say (1, 3):

Constant of proportionality, k = y/x = 3/1

k = 3

To write the equation that gives the number of servings, y, in x pints of frozen yogurt, substitute k = 3 into y = kx:

y = 3x

The equation is: y = 3x.

The value of x in the parallel lines is 102 degrees.

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angle, linear angles, alternate interior angles, alternate exterior angles, vertically opposite angles etc.

Therefore, let's find the value of x using the angle relationships.

Alternate exterior angles are the pair of angles on the outer side of the two parallel lines but on the opposite side of the transversal.

Therefore,

x = 102 degrees(alternate exterior angles)

Alternate exterior angles are congruent.

Part (a)

The compound interest formula is

A = P*(1+r/n)^(n*t)

where,

For option 1, we have these values:

Plug them into the formula to get:

A = P*(1+r/n)^(n*t)

A = 4000*(1+0.018/4)^(4*3)

A = 4221.4270078004

A = 4221.43

The account balance after three years is $4221.43

Then subtract off the deposit to find the interest made.

i = A - P

i = 4221.43 - 4000

i = 221.43

Answer: Option 1 pays $221.43 in interest.

====================================================

Part (b)

If n heads to infinity, then the compound interest formula is replaced with the continuously compounded interest formula.

That formula is

A = P*e^(r*t)

where the new item 'e' is a special constant.

e = 2.718...

It's similar to how pi = 3.14...

Most calculators have an "e" button, so it's best to let the calculator handle the decimal digits of "e".

For option 2, we have:

So,

A = P*e^(r*t)

A = 4000*e^(0.015*3)

A = 4184.11143963493

A = 4184.11

and,

i = A - P

i = 4184.11 - 4000

i = 184.11

Answer: Option 2 pays $184.11 in interest.

Using percentage error, the error factor is ± 2.15 inches and the smallest size is 40.85 inches and largest size is 45.15 inches.

Percent error is the difference between estimated value and the actual value in comparison to the actual value and is expressed as a percentage. In other words, the percent error is the relative error multiplied by 100.

The formula of percentage error is given as

P.E = [(actual value - estimated value) / actual value] × 100

Since we know the percentage error and actual value, we can find the difference or actual error by;

5 / 100 = x / 43

0.05 = x / 43

x = 2.15

The increase of decrease in size is by a factor of ± 2.15

The smallest size = 43 - 2.15 = 40.85 in

The largest size = 43 + 2.15 =  45.15 in

The smallest and largest size are 45.15 and 40.85 inches respectively

Answer:

Step-by-step explanation:

To find the cost of Wilson's bus ticket, we first need to determine how many additional miles he traveled beyond the first 10 miles. Since the ticket price was $0.50 per 1/2 mile, we can divide the number of additional miles by 0.5 to find the number of additional 1/2 miles. For example, if Wilson traveled 12 miles, he would have traveled 2 miles beyond the first 10 miles. Dividing 2 by 0.5, we get 4, so he would have traveled an additional 4 1/2 miles.

Once we know the number of additional 1/2 miles, we can multiply that number by the ticket price per 1/2 mile to find the cost of the additional portion of the ticket. For example, if the ticket price was $0.50 per 1/2 mile and Wilson traveled an additional 4 1/2 miles, the cost of the additional portion of the ticket would be 4.5 * $0.50 = $2.25.

Finally, we can add the cost of the initial portion of the ticket, which was $5.00 for the first 10 miles, to the cost of the additional portion to find the total cost of the ticket. For example, if the initial portion of the ticket was $5.00 and the additional portion was $2.25, the total cost of the ticket would be $5.00 + $2.25 = $7.25.

In conclusion, to find the cost of Wilson's bus ticket, we need to divide the number of additional miles he traveled beyond the first 10 miles by 0.5 to find the number of additional 1/2 miles, multiply that number by the ticket price per 1/2 mile to find the cost of the additional portion of the ticket, and then add that amount to the cost of the initial portion of the ticket to find the total cost.

An equation whose solution is the number of months, m, it takes for the account balance to reach $2000 would be the initial balance minus the monthly rent times the number of months equals $2000.

Given:

initial balance : $4800

Since the account starts with $4,800 and decreases by $400 each month, there will be 4800−400m dollars left in the account after m months have passed.
