please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

Because..
y = °
I solved this by:
Please help
Answer:
x = 35° and y = 72.5
Step-by-step explanation:
The value of x = 35° {because they are vertically opposite angles )
Now, the the value of y
=> y + y + 35° = 180° { sum of angles on a straight line is 180° }
=> 2y + 35 = 180°
=> 2y = 180 - 35
=> 2y = 145
=> y = 145/2
=> y = 72.5
Hey how do you divide A fraction?

Find the value of k. Give your answer in degrees.
Answer is 25 degrees.
Answer:
k=12
Step-by-step explanation:
Top left angle is 84 degrees also, due to alternate interior angles cut by the transveral.
2 sides are congruent, leaving bottom left corner angle also 84 degrees.
Write an equation to solve for k:
84+84+k=180
simplify
168+k=180
subtract 168 from both sides
k=12

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30

Answer:
1st) Surface Area = 178.7 cm²
Volume = 105 cm³
2nd) Surface Area = 51 m²
Volume = 15 m³

A group of fifth grade students was asked how much time they spend each night on homework. The results are shown in the line plot. Which of the following statements are true? 4 students said they do more than 1 hour of homework each night. 20 students were questioned. All of the students said they do homework every night. The range of the results is 2 hours. The mode of the results is 1 hour.
There is more than 1 answer
Answer:
0-16
Step-by-step explanation:
since it tells you 4 students does homework does more then one hour and 20 students were questions there is a chance that the other students who answered will take less time. A mode is when one number appears the most in your case it’s the number of students that appears the most in you line plot. Example: 2 students take one hour (put 2 dot on one) 5 students take 2 hours (put 5 dot on two hour) and 1 student takes 2.5 hours (put a dot on 2.5) then the mode for this example the mode is 5

Pls, help! A standard number cube with the numbers 1 through 6 is rolled. Find the probability of rolling a number less than 3. Find the probability of not rolling a number less than 3.
1/3; 2/3
1/2; 1/2
5/6; 1/2
1/6; 5/6
Brainlist for positive attitude and correct answer :D
Answer: The correct answer is:
Probability of rolling a number less than 3: 2/6 or 1/3
Step-by-step explanation:
Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.
Probability of not rolling a number less than 3: 4/6 or 2/3.
Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D
