Answer:
B
Step-by-step explanation:
Plug in coordinates to see if they match the answer.
It's easier in slope-intercept form, so lets change it first.
-2x+y=7
+2x +2x
y=2x+7
Now we can plug in the coordinates to see if they match.
Lets try A.
11=2(-2)+7
11=-4+7
11=3
A is incorrect.
Lets try B.
11=2(2)+7
11=4+7
11=11
B is a solution, therefore is on the graph.
Answer:
On the circle
Step-by-step explanation:
The distance between D and G is:
If point J is not exactly this far, then it is not on the circle.
Therefore, it is on the circle. Hope this helps!
10 students averaged 80, so the sum of their scores was (10 x 80) = 800
20 students averaged 89, so the sum of their scores was (20 x 89) = 1,780
All together, the sum of all 30 scores was (800 + 1,780) = 2,580
30 students totaled 2,580, so their average was (2,580 / 30) = <em> 86</em> .
<span>3x</span>² <span>- 8x -3 = 3x</span>² - 9x + x - 3 =
= 3x² - 9x + x - 3 = 3x* ( x - 3) + 1* (x - 3) =
= 3x * (x - 3) + 1 * (x - 3) = (3x + 1) (x - 3)
Answer (3x + 1) (x - 3)
A real world problem is considered a problem that can either be A: Solved in any method. B:has words and numbers So you would write for instant Charlie went to the store he bought 7 items that costed 21.99 how much money does he have left after spending it on the items? Can you solve it no you cannot why? Because it doesnt have the amount of money he was allowed to spend thats what missing information is. Now extra information is when there is something in the problem <span>you DO NOT NEED to solve. Hope that helps you out.</span>
