Answer:
B. is the answer
Step-by-step explanation:
y>-3x+2
let's do one by one
A. Is 2>-3(-4)+2? negative times negative is positive so 2 is not greater than 12 +2 or 14
B. is 2>-3(4)+2? -3•4=-12 +2 =-10 so yes 2>-10
C. is -2>-3(-2)+2? negative •negative is positive 6+2=8 so -2 is not greater than 8
D. is 0>-3(-4)+2? -•-=+ so 12+2=14. so 0 is not greater than 14

- <u>length</u><u> </u>= 12km
- <u>brea</u><u>d</u><u>t</u><u>h</u><u> </u>= 2km

- Area of rectangle = length × breadth .
<u>procedure</u><u> </u><u>:</u>
putting value of the given data into formula :
Area of rectangle = 12km ×2 km
= 24km ^2
Ans = 24km^2

Answer:
8x + 20 ≥ 25
Step-by-step explanation:
Well 8 times the sum of a number "x" plus 20,
So we can write the following,
8x + 20
and that should be greater than or equal to 25
8x + 20 ≥ 25
<em>Thus,</em>
<em>as an inequality it is 8x + 20 ≥ 25.</em>

Answer:
xy ≈ 2.3
Step-by-step explanation:
Logarithms can be used to find x and y.
3^x = 4
x·log(3) = log(4)
x = log(4)/log(3)
__
4^y = 12
y = log(12)/log(4)
__
Then xy is ...
xy = log(4)/log(3) × log(12)/log(4) = log(12)/log(3)
xy ≈ 1.079/0.477
xy ≈ 2.26
Answer:
87.471
Step-by-step explanation:
Given that scores for test, quiz, final exam , average quizzes.
There are weight given as 55% for quiz, 30% for homework, 5% Final Exam 10% Tests:
Now to calculate the student final grade, we can use weighted average method.
Final exam average
67
90
44
29
100
100
100
75.71428571
Use the averages to find:
Score Weight Score*weight
Quizzes 90 55% 49.5
Homework 85 30% 25.5
Tests 75.71 10% 7.571
final exam 98 5% 4.9
total 87.471
Hence answer is 87.471
