Answer:
B, E and F.
Step-by-step explanation:
The transformation f(x) ------> f(x + a) moves f(x) a units to the left.
So when there is an increase in the number added to x in the parentheses the graph moves to the left.
So B is one because of the (x - 1)2 ---> (x + 1)2
The others are E and F.
Answer:
6. x = 15
7. JL = 78
Step-by-step explanation:
6. 8x - 23 = ½(10x + 44) (midsegment theorem)
Multiply both sides by 2
2(8x - 23) = 10x + 44
16x - 46 = 10x + 44
Collect like terms
16x - 10x = 46 + 44
6x = 90
Divide both sides by 6
x = 90/6
x = 15
7. MN = 5x - 16
JL = 4x + 34
MN = ½(JL) (midsegment theorem)
5x - 16 = ½(4x + 34) (substitution)
2(5x - 16) = 4x + 34
10x - 32 = 4x + 34
Collect like terms
10x - 4x = 32 + 34
6x = 66
x = 66/6
x = 11
JL = 4x + 34
Plug in the value of x
JL = 4(11) + 34 = 44 + 34
JL = 78
MEAN means ADVERAGE
MODE means MOST
RANGE means LARGEST # - SMALLEST # = the "CHANGE" OF RANGE
MEDIAN means MIDDLE
ANSWER B》MODE
Answer:
3 2/3
Step-by-step explanation:
7(3x-4)=49
21x-28=49
21x=77
x=3 2/3
Answer:
x = 9
y = 6
Step-by-step explanation:
ΔABC ~ ΔPQR
Therefore, corresponding sides of these similar triangles will be in the proportional.
x = 
x = 9
Similarly, 
y = 
y = 6
