Answer:
A #1 ( x+2)2 (x-2)2
Step-by-step explanation:
it is the only one that could possibly work
Answer= c
In this case you've got to place the vector from the origin, so you have to get the difference from both points (x2-x1) and (y2-y1)
So you get that the vector from the origin is (18,-7)
Know you know the vector v is three times the vector u, so you multiply three times the vertex, but remember the vector v goes int he opposite direction, so the vector v from origin the the terminal point is (-54, 21)
The <u>correct answers</u> are:
#1) Open; there is a variable;
#2) Yes;
#3) No;
#4) (-10, -30); and
#5) (10, -86).
Explanation:
#1) An open sentence is one that contains a variable. This has a variable, p, on each side, so it is an open sentence.
#2) Solving the equation
2 - 8x = -6
Subtract 2 from each side:
2 - 8x - 2 = -6 - 2
-8x = -8
Divide both sides by -8:
-8x/-8 = -8/-8
x = 1
The answer is yes.
#3) For the equation y = 4x, to see if (3, 13) is a solution, substitute 3 for x:
y = 4(3)
y = 12
Since it is not 13, (3, 13) is not a solution.
#4) For the equation y = 3x, if we substitute -10 for x, we have:
y = 3(-10) = -30
The solution would be (-10, -30).
#5) For the equation y = -9x + 4, substitute 10 for x:
y = -9(10) + 4
y = -90 + 4
y = -86
The solution would be (10, -86).
Answer:
mean: 8.4 median: 7 mode: 6
Step-by-step explanation:
mean add all the numbers up and divide them by how many of them there are.
median put them in order smallest to largest then find the middle number
mode the number that comes up in the line the most
