2.3 + r = 7.1
solve for r

Answers

Answer 1

Answer:

2.3+r=7.1

move all terms to the left:

2.3+r-(7.1)=0

add all the numbers together, and all the variables

r-4.8=0

move all terms containing r to the left, all other terms to the right

r=4.8 is the answer

Answer 2

Answer:

r = 4.8

Step-by-step explanation:

2.3 + r = 7.1

r + 2.3 = 7.1

r = 7.1 - 2.3

r = 4.8

The United States had no chance at stopping

so.
The United States might not have been able
to stop the attacks, but it could have made a

Since the plotters were flexible and

Suppose the system of linear equations has no solution. Which is NOT a possible value of the constant for the second equation?

6x + 9y = 15
2x + 3y = __

A) 5
B) 10
C) 15
D) 20

Answers

Answer:

  A)  5

Step-by-step explanation:

The coefficients of the second equation are 1/3 of those of the first equation. If the constant of the second equation is also 1/3 of the constant of the first equation, then the equations are dependent, and will have an infinite number of solutions.

The constant must be something other than 1/3·15 = 5 to make the equations inconsistent, having no solutions.


Find the slope of the line that passes through (57, -27) and (-19, -34)

Answers

Answer:

10.86

Step-by-step explanation:

m = Y2 - Y1 / X2 - X1 = -19 -57 / -34 +27 = -76 / -7 = 10.86

Answer:

y=7/76x-129/4

Step-by-step explanation:

I'm going to assume you want this in slope intercept form.

The equation of a line is equal to y = mx+b

Where m is the slope and b is the y-intercept.

The slope of a line is a measure of how steep the line is.

For lines like these, the slope is always defined as "the change in y over the change in x" or, in equation form:

y2-y1/x2-x1

So what we need now are the two points you gave that the line passes through. Let's call the first point you gave, (57,-27), point #1, so the x and y numbers given will be called x1 and y1, and the second point will be x2 and y2.

So we just plug in the numbers, and find the slope to be 7/76.

What about b(the y-intercept), I can already hear you typing. Well, to do that, you plug in the coordinates of the points given and solve for b.

And there you have it:

y=7/76x-129/4 is the equation of the line.

What is a rectangle?

A rectangle is defined as a four-sided shape with opposite sides that are equal in length and parallel to each other.

A parallelogram is defined as a special type of quadrilateral that has both pairs of opposite sides parallel and equal.

The dimensions of the rectangle that Michael should draw are:

Length = AB = CD = 4 units (horizontal side of the parallelogram)

Width = AD = BC = 4 units (vertical side of the parallelogram)

This creates a rectangle with dimensions of 4 units by 4 units.

What are Vertical and Horizontal Asymptotes?

A vertical asymptote of a function is the vertical line x = c such that the function tends to approach to infinity as the value of x approaches a.

Horizontal asymptote is the horizontal line y = d, such that the function approaches this line as the value of x approaches positive or negative infinity.

Given function is,

y = 2 (3)⁽ˣ⁺⁷⁾ - 5.

Horizontal asymptote of an exponential function y = kˣ is the line y = 0.

If the parent function is transformed and becomes something of the form y = akˣ + d, then the horizontal asymptote if the line y = d.

Here, the value instead of d = -5.

So the horizontal asymptote is y = -5.

Hence the correct option is C. y = -5.

An airplane is preparing to land an airport. It is 34,800 feet above the ground and descending at the rate of 3,000 feet per minute. At the same airport, another airplane is taking off and will ascending at the rate of 2,800 feet per minute. When will the two airplanes be at the same altitude and what will that altitude be?

Answers

Answer:

6 mins, and the altitude will be 16,800 ft

Step-by-step explanation:

1st: Subtract 3000 from 34800

2nd: Multiply 2 to 2800

Keep doing this until you get the same altitude for each one.

Final answer:

After 6 minutes, both airplanes will be at an altitude of 16,800 feet. This is found by solving two equations for the descending and ascending planes and determining the time when their altitudes are equal.

Explanation:

To determine when two airplanes will be at the same altitude, we can set up an equation where the altitude of the descending airplane equals the altitude of the ascending airplane.

Let t be the time in minutes after the planes have begun their ascent and descent respectively.

The descending airplane starts at 34,800 feet and descends at 3,000 feet per minute. Therefore, its altitude after time t will be:

Altitude of descending plane = 34,800 feet - (3,000 feet/minute × t)

The ascending airplane starts at the ground level and ascends at 2,800 feet per minute. Thus, its altitude after time t will be:

Altitude of ascending plane = 0 feet + (2,800 feet/minute × t)

To find the time when the altitudes are equal:

34,800 feet - (3,000 feet/minute × t) = (2,800 feet/minute × t)

Solving for t, we get:

t = 34,800 feet / (3,000 feet/minute + 2,800 feet/minute)

t = 34,800 feet / 5,800 feet/minute

t = 6 minutes

Now, to find the altitude at which they will be at the same level, we can plug t back into either equation for altitude:

Altitude at 6 minutes = 2,800 feet/minute × 6 minutes

Altitude at 6 minutes = 16,800 feet

Therefore, after 6 minutes, both airplanes will be at an altitude of 16,800 feet.

Answers

Answer:

Camels has to pay $42 more as interest

Step-by-step explanation:

We are given that Carmela borrows $400 and will pay 5.25% yearly simple interest.

Principal = $400

Rate of interest = 5.25%

Time = 2 years

Formula :[tex]SI = \frac{P \times T \times R}{100}[/tex]

So, [tex]SI =\frac{400 \times 2 \times 5.25}{100}[/tex]

SI=42

She borrows the money for 4 years instead of 2 years,

So,[tex]SI =\frac{400 \times 4 \times 5.25}{100}[/tex]

SI=84

Difference in interests = 84-42 = 42

Hence Camels has to pay $42 more as interest

Answer:she has to pay 42 dollars more

Jon’s weight loss for each week of the month is 5 lbs., 2.5 lbs., and 2.5 lbs. He gained 3.5 lbs. the last week. If Jon originally weighed 198 lbs., how much does he weigh now? *

Answers

Answer:

191.5 lbs.

Step-by-step explanation:

His weight loss for each week of the month is:

Week 1: 5 lbs. Week 2: 2.5 lbs. Week 3: 2.5 lbs.     On the final week he gained 3.5 Ibs.

We know his original weigh was 198 lbs. So subtract 198 from 10 (sum from adding his weight loss). You get 188 lbs. Finally add the amount of pounds he gained on the final week. 188 lbs. + 3.5 lbs. = 191.5 lbs.

Please mark as brainliest if you found helpful.

Final answer:

Jon's total weight loss for the month is 10 lbs., but he gained 3.5 lbs. the final week. This makes his total weight change 6.5 lbs. Thus, from his original weight of 198 lbs., his weight after a month is 191.5 lbs.

Explanation:

To find out Jon's weight now, we must calculate the total weight change. Jon lost 5 lbs. in the first week, then 2.5 lbs. both in the second and third week. He, however, gained 3.5 lbs. in the last week. Therefore, the total change in weight is calculated as follows:

Weight loss in the first three weeks = 5 lbs. + 2.5 lbs. + 2.5 lbs. = 10 lbs. Total weight change = Weight loss - Weight gain = 10 lbs. - 3.5 lbs. = 6.5 lbs.Jon's weight after the month = Original weight - Total weight change = 198 lbs. - 6.5 lbs. = 191.5 lbs.

So, Jon now weighs 191.5 lbs.
