Step-by-step explanation:
Answer:
(4,0)
Step-by-step explanation:
The object is first at (0,0)
It is reflected across line x=-2, this means you draw the mirror line at x=-2 and count 2 equal units backwards to get the image.The image will be at ;
The image (-4,0) is then reflected on the y-axis
You know reflection on the y-axis, the y-coordinate remains the same but the x-coordinate is changed to its opposite sign.
Hence;
(- -4,0)= (4,0)
The image will move 8 units towards positive x-axis.This is the same as moving 4 units from the mirror line at (0,0) and land at (4,0)
When it tells you to find h(2), that means you plug in 2 for x.
If 2x^3 (to the third power)
2(2)^3-3
1. PEMDAS, exponents first
2^3=8
2. multiply
8x2=16
3. subtract
16-3=13
Hope this helps!
Answer:
60ml of the 50% alcohol solution and 20ml of the 6% alcohol solution
Step-by-step explanation:
We can build a system of equation for solve this problem
x = first solution
y = second solution
x + y = 80
0.5x + 0.06y = 80 * 0.39
x + y = 80
0.5x + 0.06y = 31.2
x = 80 -y
0.5(80-y) + 0.06y = 31.2
40 - 0.5y + 0.06y = 31.2
-0.44y = -8.8
y = 20
x = 80 - 20 = 60
