Answer:
that correct answer is D, Substitute the coordinates x and y-value in the equation, (12 is the x-value, 10 is the y-value). 10 is not equal to 22 + 12, so the correct answer is D.
Hope this helps!
Step-by-step explanation:
A=(1,2,3)
B=(0,1,2)
A×B=(1,2,3)×(0,1,2)
A×B=((0,1),(1,1),(1,2),(0,2),(1,2),(2,2),(0,3),(1,3),(2,3))
<em>In 4 hours.</em>
Just equate f(x) = g(x). So:
15x + 90 = 30x + 30
60 = 15x
<em>x = 4 hours.</em>
