How do you write y - 3 -
(x + 4) in slope intercept form?
Answer:
y = x + 7
Step-by-step explanation:
Your original equation was:
y - 3 = (x+4)
First distribute
= (x+4)
Since there is no a value, then there is an invisible one and your result is:
y - 3 = x + 4
Then add 3 to both sides to get:
y = x +4 +3
y = x + 7
Since the slope-intercept form of a line is y = mx + b
where m is the slope and b is the intercept, then your equation is now in slope-intercept form.

suppose that grade point averages of undergraduate students at one university have a bell shaped distribution with a mean of 2.61 and a standard deviation of 0.45.
Using the empirical rule, what percentage of the students have grade point averages that are at least 2.16? Please do not round your answer.
84% of the students have grade point averages that are at least 2.16
Empirical rule
Empirical rule states that for a normal distribution, 68% are within one standard deviation from the mean, 95% are within two standard deviation from the mean, 99.7% are within three standard deviation from the mean.
68% = mean ± standard deviation = 2.61 ± 0.45 = (2.16, 3.06)
The percentage of the students have grade point averages that are at least 2.16 = 68% + (100% - 68%)/2 = 84%
84% of the students have grade point averages that are at least 2.16

The radius is 7 and Center is at (- 2, 5).The equation is:
(x - h)² + (y - k)² = r² or(x + 2)² + (y - 5)² = 7² or(x + 2)² + (y - 5)² = 49----------------------------------------------

Find the equation of the exponential function represented by the table below:
Answer:
[tex]y=0.1(4)^x[/tex]
Step-by-step explanation:
Exponential functions are represented by the formula [tex]y=a(b)^x[/tex], where a is the initial value, and b is the multiplier.
Here, we can see that when x = 0, or our initial value, y = 0.1.
Thus, a = 0.1.
Since b is the multiplier, or like the slope, we can do 0.4/0.1 and get 4 for our multiplier.
Now plug everything into the formula [tex]y=a(b)^x\\y=0.1(4)^x[/tex]

Answer:
n = 11Step-by-step explanation:
We can observe general terms of n:
aₙ = n + 1 + 2n + 2 + 3n + 3 + ... + (n - 1)n + (n - 1)Rewrite it as:
aₙ = (n + 1) + 2(n + 1) + 3(n + 1) + ... (n - 1)(n + 1) = (n + 1)(1 + 2 + 3 + ... + n - 1) = (n + 1)(1 + n - 1)(n - 1)/2 = (n - 1)n(n + 1)/2We need to find the least n for which aₙ > 500:
(n - 1)n(n + 1)/2 > 500 ⇒ (n - 1)n(n + 1) > 1000If n = 10:
a₁₀ = 9*10*11 = 990 < 1000If n = 11:
a₁₁ = 10*11*12 = 1320 > 1000So the least n is 11
If I'm understanding the construction of this sequence correctly, we have
• a₁ = 0
(the sum is empty since there is no positive integer b such that b•1 + b = 1)
• a₂ = 3
(since 3 = 1•2 + 1)
• a₃ = 4 + 8 = 12
(since 4 = 1•3 + 1 and 8 = 2•3 + 2)
• a₄ = 5 + 10 + 15 = 30
(since 5 = 1•4 + 1, 10 = 2•4 + 2, and 15 = 3•4 + 3)
and so on.
Notice that for n ≥ 2, aₙ is simply the sum of the first n - 1 multiples of n + 1. So
[tex]\displaystyle a_n = \sum_{i = 1}^{n - 1} (n+1)i[/tex]
Recall that
[tex]\displaystyle \sum_{i=1}^n i = \frac{n(n+1)}2[/tex]
Then
[tex]\displaystyle a_n = (n+1) \sum_{i=1}^{n-1} i = (n+1) \cdot \frac{(n-1)n}2 = \frac{n(n^2-1)}2[/tex]
Solve for n such that aₙ > 500 :
n (n² - 1)/2 > 500
n (n² - 1) > 1000
n³ - n > 1000
We can solve this by inspection. Noticing that 10³ = 1000, if we replace n = 10 we get
10³ - 10 = 990 > 1000
which is false, but the difference is quite small. So we move up to n = 11 and find
11³ - 11 = 1320 > 1000
which is true, so n = 11 is the least number such that aₙ > 500.

Lily works 14 hours and earns $329. Aaron's hourly rate is 3/5 of Lily's. Aaron earns $310.20. What is Aaron's hourly rate? How many hours does Aaron work?
Pls help!
The time of work for Aaron is 22 hours and Aaron's hourly rate is $14.1.
What is multiplication?One of the four fundamental mathematical operations, along with addition, subtraction, and division, is multiplication. Multiply in mathematics refers to the continual addition of sets of identical sizes.
Given:
Lily works 14 hours and earns $329, Aaron's hourly rate is 3/5 of Lily's, Aaron earns $310.20,
Calculate Aaron's hourly rate as shown below,
Aaron's hourly rate = 3 / 5 of Lily's
Aaron's hourly rate = 3 / 5 × 329 / 14
Aaron's hourly rate = 987 / 70
Aaron's hourly rate = 14.1
Thus, Aaron's hourly rate is $14.1.
The time of work for Aaron = 310.2 / 14.1
The time of work for Aaron = 22 hours

The next element in sequence is 13, so completed sequence would look like 29,23,19,17,13,11
How to find the missing element in a sequence?For that we need to figure out how the sequence's elements are getting generated. Then we can apply the same formula to find the next values of the sequence.
The sequence given in the problem is: 29,23,19,17,13,?
We can see that the numbers listed are prime numbers, starting from 29, and going decreasing.
The number that will come in place of "?" is going to be such that it is prime number and come exactly before 13. Before 13, there are primes 2,3,5,7, 11
11 is closest to 13,
Thus, the next element in sequence is 13, so completed sequence would look like 29,23,19,17,13,11
