Percent means parts out of 100
105%=105/100=1.05
'of' means multiply
105% of 260=1.05 times 260=273
Answer:
y = -2x -3
Step-by-step explanation:
- the altitude trough F is a perpendicular line to the line DE
- find slope of line DE
D ( x2 = -5, y2 = -1); E (x1 = 3, y1 = 3)
slope m = (y2-y1) / (x2-x1) = (-1-3) / (-5-3) = -4/ -8 = 1/2
-find equation of the altitude trough F
lines that are perpendicular have the slope negative reciprocal (negative reciprocal of 1/2 is -2)
y= -2x +b , for point F(1, -5)
-5 = -2*1 +b, add 2 to both sides
-5 +2 = b, combine like terms
-3 =b
equation of the altitude trough F is y = -2x -3
Answer:
Step-by-step explanation:
Using the quadratic formula:
Since the discriminant is negative, -31, there are no real roots

<u>Question </u>
Select the three equations that this diagram could represent.
<u> </u>
<u>Answer</u>
<em>Well, we first have to find out what the diagram says.</em>
<em>So what the diagram says is that 18 + 18 + 18 = 54.</em>
<em>Given this information, we have to figure what other answers = 54.</em>
<em>Therefore the answers are </em>
(A) 18 * 3 = 54.
(D) 54/18 = 3
(E) 54/3 =18
