Answer:
Point A, B, and C are collinear points.
Step-by-step explanation:
When points lie on one line, meaning all of the points are on the same line --> this is known as collinear points.
Set up a proportion. 6/10 = 9/x. cross multiply so x times 6 = 6x. And 10 times 9 = 90. so 6x=90. Then 90 and 6x divided by 6. which gets you x=15. The 9 ft tall elephant will cast a 15 ft shadow.
Answer:
9(n + 22) ≤ -15
Step-by-step explanation:
9 times the sum of a number and 22 is at most −15
Let n = number
Times = multiplication
Sum = Addition
9 * n + 22
We must add parenthesis on the end on 22 and before n
We must do this because it says 9 times the sum of a number and 22 which means that 9 is being multiplied by both n and 22
We would have 9(n + 22)
9(n + 22) is at most -15
At most meaning that -15 is the highest number that 9(n + 22) can equal
Because it says at most 9(n + 22) can equal -15 or anything less than -15
So at most can be replaced with ≤
9(n + 22) ≤ -15

Step-by-step explanation:
PLATO
2(3x+16)
Step-by-step explanation:
Identify the expression equivalent to 4(x + x + 7) − 2x + 8 − 4
4(x + x + 7) − 2x + 8 − 4
When x=1 , the expression becomes 4(1+1+7)-2(1)+8-4=38
When x=2 , the expression becomes 4(2+2+7)-2(1)+8-4=44
Plug in x=1 and check with each expression
6x + 11 =6(1) +11= 16
3(x + 7) = 3(1+7)= 3(8)= 24
2(3x + 16) = 2(3(1)+16)= 38 , we got same answer when x=1, now check with x=2
2(3x + 16) = 2(3(2)+16)= 44
3x + 16= 3+16= 19
