Answer: 60%
Step-by-step explanation:
Given: Climbing rate at the end of week 1 = 25 steps per minute.
Climbing rate at the end of week 4 = 60 steps per minute
The percent increase in Maggie's rate of climbing steps from the end of week 1 to the end of week 4 will be :
[tex]\dfrac{\text{Climbing rate after week 4 - Climbing rate after of week 1}}{\text{Climbing rate after week 1}}\times100[/tex]
[tex]=\dfrac{40-25}{25}\times100\\\\=\dfrac{15}{25}\times100=15\times4=60\%[/tex]
Hence, the percent increase in Maggie's rate of climbing steps from the end of week 1 to the end of week 4 = 60%
is a relation that is also a function.
{(1,6), (1,7), (7, 8), (8, 9)}
{(2,3), (3, 2), (2, 4), (4, 2)}
{(0, 1), (0, 2), (0, 3), (0,4)}
|{(1, 1), (3, 2), (6,3), (8,4)}
Answer:
The relation {(1, 1), (3, 2), (6,3), (8,4)} is also a function ⇒ D
Step-by-step explanation:
The relation formed from a set of ordered pairs could be a function if every x-coordinate has only one y-coordinate corresponding to it
Examples:
The relation {(1, 3), (-2, 5), (1, -2)} is not a function because x = 1 has two values of y 3 and -2The relation {(2, -3), (-2, 0), (1, 5)} is a function because x = 2 has only y = -3, x = -2 has only y = 0, and x = 1 has only y = 5Let us check all the relation to find which one is a function
∵ The relation is {(1, 6), (1, 7), (7, 8), (8, 9)}
∵ At x = 1, y = 6 and 7
→ x has two values of y
∴ The relation is not a function
∵ The relation is {(2, 3), (3, 2), (2, 4), (4, 2)}
∵ At x = 2, y = 3 and 4
→ x has two values of y
∴ The relation is not a function
∵ The relation is {(0, 1), (0, 2), (0, 3), (0,4)}
∵ At x = 0, y = 1, 2, 3, and 4
→ x has four values of y
∴ The relation is not a function
∵ The relation is {(1, 1), (3, 2), (6,3), (8,4)}
∵ At x = 1, y = 1
∵ At x = 3, y = 2
∵ At x = 6, y = 3
∵ At x = 8, y = 4
→ Every x has only one value of y
∴ The relation is a function
∴The relation {(1, 1), (3, 2), (6,3), (8,4)} is a function

Point Slope Form : y - y1 = m(x- x1) Write the equation of the line described that passes through (-8,-5), parallel to y = -3x + 9
Answer:
y + 5 = -3(x + 8)
General Formulas and Concepts:
Point-Slope Form: y - y₁ = m(x - x₁)
x₁ - x coordinate
y₁ - y coordinate
m - slope
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Parallel Lines always have the same slope but different y-intercepts.
Step-by-step explanation:
Step 1: Define
Given (Parallel Line): y = -3x + 9
Point (-8, -5)
Step 2: Find variables
Slope m of parallel lines = -3
Step 3: Find parallel line equation
y₁ = -5
x₁ = -8
m = -3
y + 5 = -3(x + 8)

Answer:
The correct option is;
1, 6, 11, 15
Step-by-step explanation:
The given information are;
The function that defines the terms of the sequence is f(n) = f(n - 1) + 5
Where;
n = The number of the term
For n = 1, we have, f(1) = -4
The first four terms are therefore;
f(2) = f(2 - 1) + 5 = f(1) + 5 = - 4 + 5 = 1
f(3) = f(3 - 1) + 5 = f(2) + 5 = 1 + 5 = 6
f(4) = f(4 - 1) + 5 = f(3) + 5 = 6 + 5 = 11
f(5) = f(5 - 1) + 5 = f(4) + 5 = 11 + 5 = 15
The first four terms are; 1, 6, 11, 15

Please help!!! Tony wants to build a fence around his rectangular garden that has
dimensions 20 ft by 35 ft. His fence posts need to be placed 5 ft apart.
How many posts will Tony need to buy?
I
Answer:
22 posts
Step-by-step explanation:
on the side of 20 feet you have 5 fence posts each in including one on each of the corners. On the 35 feet side you would have 8 including the corners, but since the corner posts are done its 6 on each 35 feet side. So you get 5+5+6+6=22

Which of the following values of x solves 3(x−6)=18?
Answer: X=12
Step-by-step explanation: 3(x-6)=18 becomes 3x-18=18 which is 3x=36 because you add 18 to both sides. Then you simplify 36/3 which is 12
Answer:
x=12
Step-by-step explanation:
3(x-6) = 18 - distrubute ( you are solving for x )
3x - 18 = 18 - add 18 to both sides
3x = 36 - divide
x =12

Which statement or statements accurately describe a good way to avoid excessive service fees?
1. Try to deposit money in large batches rather than in small amounts.
II. Try to limit the number of withdrawals you make from out-of-network ATMs.
III. Try to avoid using your debit card online.
a. I and II
b. ll only
c. Ill only
d. I and III
Answer:
b. ll only
Explanation:
Remember, service fees often refer to an amount deducted to pay for the cost of providing particular services, such as ATM service charges, etc.
We can this conclusion because if one decides to deposit money in large batches rather than in small amounts; they will be directly subjecting themselves to excessive charges. Consider, most financial institutions often charge higher fees for larger deposits.
Also, if one decides to avoid using your debit card online they will tend to spend more using traditional cash methods which require increasing the number of one's ATM withdrawal.
However, by trying to limit the number of withdrawals you make from out-of-network ATMs, one saves him or herself of excessive service fees.

Question 2
Solve for y. Write your answer in slope-intercept form y= mx + b.
6x+2y = -10
Question 3
Answer:
y=-3x-5
Step-by-step explanation:
6x+2y=-10
2y = -6x-10 (you need to isolate the y and so i took 6x and subtracted it from both sides)
y = -6/2x-10/2 ( dont feel like explaining)
divide them (-6/2 and -10/2) to get
y=-3x-5

Gina tracks the low temperatures for a city over six days. Identify the days colder than-1.75°F. Monday Tuesday Wednesday Thursday Friday -2.5°F -1.9°F 0°F -1.5°F 0.5°F
Answer:
Monday
Tuesday
Step-by-step explanation:
Given the temperature data:
Mon _____ Tue _____ Wed _____ Thur ___ Fri
-2.5°F ___ - 1.9°F _____ 0°F _____ - 1.5°F _0.5°F
Days colder than - 1.75°F
Days colder than - 1.75°F are days whereby the temperature value is less than - 1.75
Hence,
-2.5°F < - 1.75°F = (Monday)
-1.9°F < - 1.75°F = (Tuesday)
Hence, temperature on Monday and Tuesday is colder than - 1.75°F
