Y = mx + b
slope(m) = 3/4
(3,7)...x = 3 and y = 7
now we sub and find b, the y int
7 = 3/4(3) + b
7 = 9/4 + b
7 - 9/4 = b
28/4 - 9/4 = b
19/4 = b
so ur equation is : y = 3/4x + 19/4
if point A (x,5) lies on the line.....
y = 3/4x + 19/4......when y = 5
5 = 3/4x + 19/4
5 - 19/4 = 3/4x
20/4 - 19/4 = 3/4x
1/4 = 3/4x
(1/4) / (3/4) = x
1/4 * 4/3 = x
4/12 reduces to 1/3 = x......so point A is (1/3,5)...with x being 1/3
To know how far your values differ apart from the mean of the records
Answer:
55.5F
Step-by-step explanation:
y = mx + b
m = slope = -3.5/1000
distance = x = 1000
b = temperature at x = 0 = 59F according to https://www.universalweather.com/blog/international-standard-atmosphere-how-it-affects-flight-understanding-the-basics/
temperature = y = ?
y = -.0035(1000) + 59
y = 55.5
Answer:
- housing, $1056
- food, $552
- transportation, $408
- savings, $240
- clothing, $144
Step-by-step explanation:
Multiply the budget total by the percentage for each category:
- housing: 44% × $2400 = $1056
- food: 23% × $2400 = $552
- clothing: 6% × $2400 = $144
- transportation: 17% × $2400 = $408
- savings: 10% × $2400 = $240
__
Find "the rest" by subtracting the total of percentages from 100%, or by subtracting the total of budget categories from $2400. Here, everything (not including savings) adds to 90% × $2400 = $2160, so the amount to savings is 10%, or $240.
Answer:
D. –5.2 + (–6.4) = –11.6
Step-by-step explanation:
First, you can eliminate A and C because 5.2 is positive. Since the red arrow is pointing left, it indicates that the number (-5.2) is negative.
Then, you look at the second arrow, the green one. It is pointing left, so it would be -6.4.
I hope this helps :)
