Answer:
The correct option is C.
Step-by-step explanation:
The quadratic parent function is
The translation is defined as
.... (1)
Where, k is vertical stretch, a is horizontal shift and b is vertical shift.
If |k|>1, then graph of parent function stretch vertically by factor |k| and if 0<|k|<1, then parent function compressed vertically by factor |k|. Negative k represents the reflection across x axis.
If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
The graph shift 1 unit right,vertically stretch by a factor of 5 , reflect over the x-axis. So, a=-1, |k|=5 and k=-5
Substitute a=-1 and k=5 in equation (1).
Therefore the correct option is C.
Answer:
5x + y = 9
3x + 2y = 4
-10x - 2y = -18
3x + 2y = 4
-7x = -14
x = 2
5(2) + y = 9
10 + y = 9
y = -1
(2, -1)
the answer is c

Answer:
2.21
Step-by-step explanation:
Total meters of wood = 7.58
first time shopping: 2.25
second time shopping: 3.12
total = 2.25 + 3.12
total = 5.37
How many more meters of wood does Jack need to buy for his school project?
Meters needed = 7.58 - 5.37
Meters needed = 2.21
Each term adds 9 to the previous term.
The first term is 57, and to find the 250th term, we'd add 9 a total of 249 times.
That's the same as adding 9 times 249, which is 2241.
57 + 2241 =
2298.
(By the way, you can represent any term
of this equation with the expression
. What we do is count one step back to find our "zeroth" term, per se, and then each addition is represented as 9 times the n. This could also be
.)
