Answer:
y = 4x-7
Step-by-step explanation:
We have a slope and a point
m = 4 (2,1)
Using the slope intercept form of the equation
y = mx+b
y = 4x+b
From the point x=2 and y =1
1 = 4(2)+b
1 = 8+b
Subtract 8 from each side
1-8 =8-8+b
-7 = b
We can write the equation by using m=4 and b = -7
y = 4x-7

What’s the area of this figure?
Awnser:
14.5 cm
Step-by-step explanation:
1*7=7, 5*3=15/2=7.5
Answer:
14.5 cm^2
Step-by-step explanation:
We can find the area by adding the area of the long rectangle and the triangle
The rectangle is 1 cm by 7 cm
A = 1*7 = 7 cm^2
The triangle is 5 cm by (7-4) =3 cm
A = 1/2 (5*3)
A = 7.5 cm^2
The total area is
7+7.5 = 14.5 cm^2

four hundred seventy-one of the one thousand contestants were girls. Girls made up what fraction of the contestants?
Answer:
The fraction is 470/1000, which can be simplified to 47/100, and that is 47%.
Step-by-step explanation:
Basically you take what is asked for and you divide it by the total amount.
470 is the amount of girls as contestants.
1000 is the total amount of contestants.
And that gives you the ratio 470/1000.

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?
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.
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.

Identify asymptote of a function y = 2(3)^x+7 – 5
O y=7
O x=7
O y=-5
Ox=-5
The asymptote of the function is y = -5.
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.

Carmela borrows $400 and will pay 5.25% yearly simple interest. How much
more interest will Carmela owe if she borrows the money for 4 years instead.
of 2 years? Show your work.
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? *
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.
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.

A) 5
B) 10
C) 15

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.

What is the data point that is the farthest from other data points when the box plot is NOT symmetrical?
A. Median
B. Outliner
C. Greatest Point
need an answer ASAP
Answer: B. Outlier
Step-by-step explanation:
An outlier is an extremely large or extremely small data value in a data set such that it appears far from the other data points when we plot data points on scatter plot or box plot.
Thus, the data point that is the farthest from other data points when the box plot is NOT symmetrical is Outlier.
Its presence affects the value of mean directly. So when a data set have outliers , we prefer Median(Mid value of a data set) as the best measure of central tendency because existence of outliers does not effect Median .
Hence, the correct option is B. Outlier.
A pathway made of slate tiles measures 513 yards long. A tile measuring 2 feet is added to the end of the pathway. What is the total length of the pathway now? 513 ft 1023 ft 18 ft 22 ft
Answer:
The total length of the pathway now is 1,541 ft
Step-by-step explanation:
To calculate the length of the pathway now, what we need to do is to have a consistency in units.
Thus, we need to convert the 513 yards to ft
Mathematically 1 yard = 3 feet
Thus 513 yards will be = 513 * 3 = 1,539 ft
Thus the total length of the pathway now will be 1539 ft + 2 ft = 1541 ft

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