Answer: n^2+5n+4r+7
Step-by-step explanation:
5x+3-4x=15-4x+3
x+3=18-4x
5x+3=18
5x=15
x=3
Answer:
[-1, 7]
Step-by-step explanation:
If you mean ...
y = 4sin(2x) +3
then you can substitute the range of the sine function into the equation and evaluate it to find the range of y.
The range of sin( ) is [-1, 1], so the range of y is ...
4[-1, 1] +3 = [4(-1)+3, 4(1)+3] = [-1, 7]
_____
<em>Comment on the problem statement</em>
The range of y = 4sin²(x)+3 will be different, and the range of 4sin(2x+3) will be different yet. It is usually a good idea to use parentheses around function arguments.
Answer:
NM corresponds with DC, and the scale factor is 3
Answer:
29.12
Step-by-step explanation:
£ : rubles
26 : 500
X : 560
X/560 = 26/500
X = 560 × 26/500
X = 728/25
