The scale factor would be 1/1
Answer:
(-4,1)
Step-by-step explanation:
The answer is (-4,1) because if you reflect any point on the y axis, the y will stay the same, but the x will become the opposite. The opposite of 4 is -4, so the coordinates are (-4,1).
Answer: 4x√5
Step-by-step explanation:
√2x • √40x=
√(2*40*x*x)=
√80x^2=
√(16*5x^2)=4x√5
There is no way to factor this so i would assume the answer is no solution.
Answer:
$150
Step-by-step explanation:
You can do this by forming an equation.
30% = 0.30. Let the original price be x dollars. Then:-
x - 0.30x = 105
0.70x = 105
x = 105/0.70
x = $150
