Answer:
thats a tough one
Step-by-step explanation:
Step 2, she didn't multiply 8 by 0.75.
Hope this helps :)
5x + 3y = 7> (4) 5x + (4) 3y = (4) 7
4x + 5y = 3> (-5) 4x + (-5) 5y = (-5) 3
20y + 12y = 28
-20x -25y = -15
(X's cross out) 12y - 25y = 28 -15
-13y = 13
Y = -1
(Plug in for y) 5x + 3(-1) = 7
5x -3 =7 (add 3 to 7)
5x = 10 (divide by 5)
X= 2
Ordered Pair= (2, -1)
Answer:
D. Positive association
Step-by-step explanation:
The line of best fit would have a positive slope
Hello!
In order to create a complete triangle, the sum of the two smaller sides must be greater than the largest side. This can be expressed using the following formula:
(S1) + (S2) > (S3)
We'll begin by inserting the first set of values into the inequality above:
3 + 6 > 10
Simplify the left side:
9 > 10
The inequality (9 > 10) is false. Therefore, the first set of values can be eliminated. Now complete the same process for the next set of values:
3 + 6 > 9
9 > 9
The inequality (9 > 9) is false. Therefore, we can eliminate the second set of values as well. Now complete the same process for the third set of values:
4 + 6 > 9
10 > 9
The inequality (10 > 9) is true. Therefore, we can confirm the third set of values (4 ft - 9 ft - 6ft) as a valid answer.
I hope this helps!
