This table gives a few (x, y) pairs of a line in the coordinate plane.
x...........y
48 -30
61 -45
74 -60
What is the x-intercept of the line?
Answers
Answer:
The x-intercept is : (22, 0)
Step-by-step explanation:
From the table values, we determine that it is a straight line as there is a constant change in x and y values.
i.e.
Any previous value of y can be obtained by subtracting 15 from the successor y value.
i.e.
60 - 15 = 45
45 - 15 = 30
so if continue, we can also determine some of the other values of y such as
30 - 15 = 15
15 - 15 = 0
Also, there is a constant change in x values. so, any previous value of x is obtained by subtracting 13 from the successor x value.
i.e.
74-13 = 61
61-13 = 48
48-13=35
35-13=22
So, from the above analysis, we determine that when the value of y = 0, the value of x = 22.
We also know that the x-intercept is the point where the line crosses the x-axis. At this point y = 0.
so, at y = 0, the value of x = 22.
Therefore, the x-intercept is : (22, 0)
Answer:
(22, 0)

HELP ME PLEASE! how do you write 610 as a scientific notation ??
Answers
If you have been looking for 610 in exponential form, 610 as a power of 10, or what is 610 in scientific notation, then you are right here, too.
In this post you can find everything about the scientific notation of 610, including the normalized form and the number written in e-notation.
Read on to learn everything about the scientific notation of six hundred and ten.
To answer the question what is 610 in scientific notation let’s recall how to convert 610 to scientific notation as detailed on our home page.
When you split the number 610 into a coefficient and a power of 10 you do get 610 in exponential form, but there is an indefinite number of possibilities.
As you probably want 610 in normalized scientific notation, the coefficient or significand of 610 in scientific notation must be in the interval [1,10[.
As there are many ways to express 610 in scientific notation, in this post we mean 610 in normalized scientific notation, unless stated otherwise. Therefore:
610 in scientific notation = 6.1 × 102.
This can also be expressed as 6.1 × 10^2, using the caret symbol, or as 6.1e+2, which is called 610 in e-notation, further discussed in the section ahead.
Regarding our converter:
Our tool changes any decimal number including 610 to standard index form. If your press the swap button, then 610 is changed back to decimal form.
Our tool displays converted numbers in a special form of scientific notation, which means that the superscripted part of × 102 is denoted by ^2.

Gavin has 50 tokens in KG use the weather roller coaster three times every hour. Gibson has 12 tokens And fines two more tokens on the ground each hour. How long until they have the same amount number of tokens
Answers
Answer:
They have the same amount of tokens after t = 7.6 hours
Step-by-step explanation:
Since Gavin initially has 50 token and rides the roller coaster three times per hour, he uses 3 token per hour. So, the number of token he losses after t hours is 3 token per hour × t hours = 3t. Thus, the number of tokens left after t hours is T = 50 - 3t
Since Gibson initially has 12 tokens and finds two tokens on the ground per hour, he gains 2 tokens per hour. So, the number of token he gains after t hours is 2 token per hour × t hours = 2t. Thus, the number of tokens he has after t hours is T' = 12 + 2t
To calculate the time t when they will have the same tokens, T must be equal to T', that is T = T'.
So, 50 - 3t = 12 + 2t
collecting like terms, we have
50 - 12 = 3t + 2t
38 = 5t
dividing both sides by 5, we have
t = 38/5
t = 7.6 hours
So, they have the same amount of tokens after t = 7.6 hours

Find the constant of variation for the relation and use it to write an equation for the statement. Then solve the equation.
If y varies as directly as the square of x, and y = 75/8 when x = 5, find y when x= 2
Answers
Answer:y=15/4
Step-by-step explanation:
start with general form y = kx. substitute in the pair of values you know for x and y.
75/8 = k(5) multiply both sides by 1/5 to solve for k, getting
15/8 = k
So your equation is y = (15/8)x substitute 2 for x to find your new y.
y = (15/8)2
y = 15/4

Formula 1 can be written alternatively as formula 2. Use algebra to show your steps how formula 1 can be manipulated to create formula 2.
Formula 1:
[tex]f(n)=\left\\ ({\sqrt[{12}]{2}}\,\right)^{n-49}\times 440\,{\text{Hz}}\,}[/tex]
Formula 2:
[tex]f(n) = 440 (2)^{\frac{n-49}{12} }[/tex]
Answers
Answer:
Steps are shown
Step-by-step explanation:
Exponent Rules
We need to recall this fundamental rule for exponents:
[tex]\displaystyle \sqrt[n]{a^m}=a^{m/n}[/tex]
We are given the expression:
[tex]f(n)=\left ({\sqrt[{12}]{2}}\,\right)^{n-49}\times 440\,{\text{Hz}}[/tex]
We'll use algebra and the above rule to manipulate the expression.
First, get rid of the unit Hz and move the coefficient 440 to the left:
[tex]f(n)=440\left ({\sqrt[{12}]{2}}\,\right)^{n-49}[/tex]
Now we convert the radical into an exponent form:
[tex]\displaystyle \left ({\sqrt[{12}]{2}}\,\right)^{n-49}=(2)^{\frac{n-49}{12}}[/tex]
Substitute:
[tex]f(n)=440\left ({\sqrt[{12}]{2}}\,\right)^{n-49}=440~(2)^{\frac{n-49}{12}}[/tex]
This is the very same expression in formula 2, as required.

write the equation of a line perpendicular to y=-2x+8 that passes through the point (-4,1)
Answers
Answer:
y = 1/2x + 3.
Step-by-step explanation:
y = -2x + 8
Gradient = -2
Gradient of the line passing through point (-4,1)
is given as 1/2. i.e it is perpendicular to y = -2x + 8
Its equation is given as:
y - y1 = m(x - x1)
y - 1 = 1/2(x -(-4))
y - 1 = 1/2(x + 4)
y - 1 = 1/2x + 2
y = 1/2x + 3.

If a die is rolled once, determine the probability of rolling a 4: Rolling a 4 is an event with 1 favorable outcome (a roll of 4) and the total number of possible outcomes is 6 (a roll of 1, 2, 3, 4, 5, or 6).
